Laryngitis
Clinical Snapshot
Laryngitis is inflammation of the larynx — most often the vocal folds themselves — and the single most common cause of an acute change in voice quality (dysphonia/hoarseness) seen in primary care and community pharmacy.[1] The overwhelming majority of cases are acute and viral, occurring alongside an upper respiratory tract infection, self-limited, and resolving within roughly 1-3 weeks without any disease-specific treatment.[1][2] This chapter also covers the genuinely distinct causes of persistent or chronic laryngitis (conventionally, symptoms lasting longer than 3 weeks) — reflux-related (laryngopharyngeal reflux, LPR) laryngitis, phonotraumatic/vocal-strain laryngitis in professional and occupational voice users, irritant and allergic laryngitis, fungal (candida) laryngitis, and the rarer autoimmune, radiation-induced, and structural causes — each of which needs its own specific workup rather than being treated as "the same laryngitis, just longer."
The single most consequential decision point in this chapter is when to look at the larynx: current guidance is that dysphonia not resolving or improving within 4 weeks, or accompanied by any of a defined set of red-flag features regardless of duration, needs laryngoscopy — because the differential at that point includes vocal fold nodules/polyps, vocal fold paralysis, and laryngeal malignancy, none of which respond to empiric medication.[1] Antibiotics and corticosteroids are both explicitly not routine therapy: acute laryngitis is a viral illness, and current evidence does not support an antibiotic benefit that outweighs the harms of unnecessary use,[2] while corticosteroids should not be prescribed for dysphonia before the larynx has actually been visualized.[1] A distinct, genuine emergency — epiglottitis/supraglottitis — can be mistaken for severe laryngitis and needs to be recognized and acted on separately (see Red Flags & Refer).
Recognize the Condition
Core symptoms
The hallmark symptom is a change in voice quality — variably described as hoarse, rough, breathy, strained, raspy, or, in severe cases, reduced to a whisper or lost entirely (aphonia). Associated features commonly include odynophonia (pain or discomfort specifically with speaking or singing — distinct from odynophagia, pain with swallowing, which points toward a pharyngeal rather than laryngeal process), a sensation of throat fullness or a lump (globus), frequent throat clearing, and a dry or mildly productive cough. Mild sore throat and low-grade systemic viral symptoms are common in the acute setting; high fever, marked systemic illness, or a rapidly worsening course point away from simple viral laryngitis (see Red Flags & Refer).
Three patterns worth distinguishing early
3 common presentations
Acute viral laryngitis
Sudden-onset hoarseness accompanying or immediately following typical upper respiratory infection symptoms — rhinorrhea, nasal congestion, sore throat, mild cough, low-grade fever. Self-limited, with the voice typically improving over 1-2 weeks as the associated URI resolves, though some residual hoarseness can persist a little longer as laryngeal mucosal inflammation settles.[1]
Reflux (laryngopharyngeal reflux, LPR) laryngitis
A more insidious, often chronic pattern: frequent throat clearing, globus sensation, a chronic non-productive cough, and a hoarse or "gravelly" voice that is often worse in the morning, with a sensation of postnasal drip or mucus stuck in the throat. Classic heartburn and regurgitation — the symptoms that define typical GERD — are frequently mild, intermittent, or entirely absent, which is exactly why LPR is under-recognized as "silent reflux" rather than reliably self-reported as a reflux problem.[3]
Chronic phonotraumatic / vocal-strain laryngitis
Gradual-onset, often fluctuating hoarseness that is worse after heavy voice use and improves with rest, in a patient with sustained high vocal demand — teachers, singers, clergy, coaches, call-centre staff, lawyers, and other professional voice users. Persistent vocal overuse and misuse can progress from simple inflammation to structural change: vocal fold nodules or polyps, and — particularly with concurrent smoking — Reinke's edema (diffuse, gelatinous submucosal swelling of the vocal folds, producing a characteristically low-pitched, rough voice).
What this is not
Stridor, drooling, a muffled ("hot potato") voice, tripod positioning, or rapid deterioration point toward epiglottitis/supraglottitis rather than simple laryngitis and need emergency assessment, not reassurance (see Red Flags & Refer). A breathy voice with aspiration on liquids, rather than a rough or hoarse quality, suggests vocal fold paralysis rather than laryngitis. Pain concentrated with swallowing rather than speaking, especially with drooling, trismus, or neck swelling, suggests a pharyngeal or deep neck space process rather than an isolated laryngeal one.
Risk Factors
- Recent or concurrent viral upper respiratory tract infection — by far the most common precipitant of acute laryngitis.
- Smoking and vaping — direct thermal/chemical irritation of the vocal folds; the dominant risk factor for Reinke's edema and an independent risk factor for laryngeal malignancy, which changes the urgency of any persistent hoarseness in a smoker (see Red Flags & Refer).
- Heavy alcohol use — a mucosal irritant in its own right, and a synergistic risk factor with smoking for laryngeal malignancy.
- Occupational or professional voice use — teachers, singers, clergy, coaches, actors, call-centre and customer-service staff, and other roles with sustained high vocal demand.[1]
- Gastroesophageal reflux disease and laryngopharyngeal reflux.[3]
- Allergic rhinitis and chronic postnasal drip.
- Dry, dusty, or chemically irritant occupational or environmental air, and low-humidity environments (winter heating, aircraft cabins).
- Inhaled corticosteroid use without a spacer and without rinsing/gargling afterward — a specific, correctable risk factor for candida laryngitis.
- Immunocompromise (chemotherapy, chronic systemic corticosteroids, poorly controlled diabetes, HIV) — raises the risk of fungal and atypical laryngitis and lowers the threshold for specialist referral.
- Prior radiation therapy to the head or neck.
- Recent endotracheal intubation or head/neck/chest surgery — a specific trigger for expedited laryngoscopy regardless of symptom duration (see Red Flags & Refer).[1]
- Excessive caffeine intake and inadequate systemic hydration.
- Rheumatologic and autoimmune disease (rheumatoid arthritis with cricoarytenoid joint involvement, granulomatosis with polyangiitis, sarcoidosis, relapsing polychondritis) — rare but genuine causes of chronic laryngitis.
- Menopause-related hormonal change — a recognized, often under-recognized contributor to voice change in some women.
Red Flags & Refer
Most laryngitis is genuinely self-limited and appropriate for supportive self-care — but any of the following changes the plan from reassurance to urgent action or prompt/expedited referral:
- Stridor, drooling, a muffled ("hot potato") voice, tripod positioning, or rapidly progressive throat pain and difficulty managing secretions — treat as possible epiglottitis/supraglottitis, a genuine airway emergency, until proven otherwise. Do not attempt to examine the oropharynx with a tongue depressor, especially in a child, since this can precipitate sudden complete airway obstruction — arrange emergency transport instead.[4][5]
- Any sign of respiratory distress — tachypnea, accessory muscle use, cyanosis, or the patient's own report of difficulty breathing rather than just difficulty speaking.
- Hemoptysis.
- Significant or progressive odynophagia or dysphagia, especially with drooling, trismus, or neck swelling — evaluate for a deep neck space infection (peritonsillar or retropharyngeal abscess) or, without infectious features, angioedema.
- Dysphonia persisting beyond 4 weeks without improvement — needs laryngoscopy, or referral to a clinician who can perform it, regardless of how mild the voice change now seems.[1]
- Any of the following, regardless of duration — these mean laryngoscopy should happen promptly rather than waiting out the usual 4-week window:[1]
- Recent surgery involving the head, neck, or chest
- Recent endotracheal intubation
- A palpable neck mass
- A history of significant tobacco use
- Professional voice user status
- Unexplained weight loss, particularly alongside hoarseness in a smoker or heavy alcohol user.
- Referred otalgia (ear pain with a normal ear exam) — a classic, easily missed feature of a laryngeal or pharyngeal lesion carried via the vagus and glossopharyngeal nerves.
- A breathy voice with aspiration on thin liquids, rather than a rough or hoarse quality — suggests vocal fold paralysis (from recurrent laryngeal nerve injury or compression by thyroid disease, lung or esophageal malignancy, or prior neck surgery) rather than laryngitis.
- Progressive or biphasic stridor in a child, especially recurrent — consider recurrent respiratory papillomatosis rather than assuming recurrent croup or laryngitis.
- Immunocompromised patients with unusually severe, rapidly progressive, or atypical laryngitis symptoms.
- Suspected caustic, thermal, or chemical injury to the airway.
Assessment & Diagnosis
History
- Onset, duration, and course — sudden versus gradual, improving versus static versus worsening.
- Voice quality — breathy, rough, strained, or aphonic — and whether it varies with vocal effort or time of day.
- Associated upper respiratory symptoms (rhinorrhea, congestion, sore throat, cough, fever).
- Reflux-type symptoms: heartburn, regurgitation, sour taste, chronic throat clearing, globus, chronic cough, morning hoarseness — remembering that classic heartburn is frequently absent in LPR specifically.[3]
- Vocal demands and occupation; smoking, vaping, and alcohol use; inhaled corticosteroid technique and rinsing habit.
- Allergen and occupational irritant exposure.
- Immunocompromise, diabetes, recent radiation therapy, recent intubation or head/neck/chest surgery.
- Systematic red-flag screen: duration beyond 4 weeks, weight loss, hemoptysis, significant odynophagia/dysphagia, otalgia, palpable neck mass, breathy voice with aspiration, and any airway-distress feature (see Red Flags & Refer).
Physical examination
Listen to the voice quality itself. Palpate the neck for a mass, asymmetry, or lymphadenopathy. Examine the oropharynx for concurrent pharyngitis, tonsillar asymmetry, or exudate. Assess for signs of a concurrent URI. Check vital signs and work of breathing specifically when any red flag is present.
When to visualize the larynx
Laryngoscopy — performed by, or on referral to, a clinician equipped to do it (typically otolaryngology, sometimes primary care with the appropriate training and equipment) — is indicated when dysphonia fails to resolve or improve within 4 weeks, or immediately, regardless of duration, if any red-flag feature is present (see Red Flags & Refer).[1] This is a genuine change from older guidance that allowed up to 3 months of empiric management before laryngeal visualization; current guidance shortens that window specifically because a meaningful minority of persistent dysphonia has a structural or malignant cause that benign empiric therapy will not address.[1] Community pharmacy and most primary care settings do not have laryngoscopy directly available, which makes this threshold a genuine referral trigger rather than something to defer.
Reflux-specific assessment tools
Two validated instruments, developed together, are widely used for suspected LPR. The Reflux Symptom Index (RSI) is a 9-item, patient-completed questionnaire — each item scored 0-5, maximum 45, with a score above 13 considered abnormal — that can reasonably be used in a primary-care or pharmacy consultation to structure the reflux-symptom history and support the decision to trial therapy.[6] The Reflux Finding Score (RFS) is an 8-item, laryngoscopy-based scale (0-26, higher is worse) scored by the clinician performing the laryngoscopy — it requires direct visualization and is therefore a specialist tool, not something completed in a symptom-only consultation.[7]
Differential diagnosis
| Category | Distinguishing features |
|---|---|
| Viral (acute) laryngitis | Sudden onset with concurrent URI symptoms; self-limited, improving within 1-2 weeks. |
| Bacterial laryngitis | Genuinely uncommon as a primary cause; consider with unusually severe, high-fever, or worsening-after-initial-improvement presentations, or in an unimmunized patient (historically, diphtheria). |
| Candida (fungal) laryngitis | Inhaled corticosteroid use without rinsing, immunocompromise, or diabetes; often coexists with oral thrush; confirmed on laryngoscopy, not diagnosed empirically. |
| Reflux (LPR) laryngitis | Chronic throat clearing, globus, morning hoarseness, chronic cough; classic heartburn often absent. |
| Phonotraumatic laryngitis / vocal fold nodules or polyps / Reinke's edema | Chronic or fluctuating hoarseness in a professional or heavy voice user, worse after vocal effort; smoking history in Reinke's edema. |
| Allergic/irritant laryngitis | Temporal association with an allergen or irritant exposure; concurrent allergic rhinitis symptoms. |
| Autoimmune/rheumatologic laryngitis | Known or emerging rheumatoid arthritis, granulomatosis with polyangiitis, sarcoidosis, or relapsing polychondritis; other systemic features usually present. |
| Radiation-induced laryngitis | History of head/neck radiotherapy; onset can be delayed well beyond the treatment course. |
| Vocal fold paralysis | Breathy voice, aspiration with thin liquids, rather than a rough/hoarse quality; investigate for recurrent laryngeal nerve compression or injury. |
| Presbylaryngis | Gradual, age-related vocal fold atrophy in an older adult; a weak, breathy voice without an acute inflammatory trigger. |
| Spasmodic dysphonia | A task-specific, strained-strangled or breathy-breaks voice pattern, often worse on the telephone, with normal mucosa on laryngoscopy — a neurologic voice disorder, not inflammation. |
| Laryngeal malignancy | Persistent hoarseness beyond 4 weeks, especially with smoking/alcohol history, weight loss, hemoptysis, otalgia, or a neck mass — see Red Flags & Refer. |
| Epiglottitis/supraglottitis | Stridor, drooling, muffled voice, toxic appearance, rapid progression — a distinct emergency, not managed in this chapter's pathway. |
| Recurrent respiratory papillomatosis | Recurrent or progressive hoarseness and stridor, typically presenting in childhood; needs pediatric ENT referral, not adult-pattern management. |
Treatment Targets
- Relieve symptoms and restore voice quality, using the least invasive effective option first.
- Identify and address the actual underlying driver — viral, reflux, phonotraumatic, irritant/allergic, fungal, or structural — rather than treating every presentation identically.
- Avoid unnecessary antibiotics for a viral illness that will not respond to them.
- Avoid empiric corticosteroids and empiric antireflux medication before the larynx has actually been assessed or reflux symptoms genuinely support it.
- Recognize and act on red-flag features (see Red Flags & Refer) rather than treating them as routine laryngitis.
- Meet the 4-week laryngoscopy threshold — do not let an empiric therapy trial quietly extend past it.
- Support vocal hygiene and prevention, particularly in professional voice users and smokers, to reduce recurrence and progression to structural disease.
- Refer promptly for voice therapy (speech-language pathology) or specialist evaluation when the driver is phonotraumatic, structural, or refractory rather than a genuinely self-limited viral illness.
Choose Initial Treatment
Uncomplicated acute viral laryngitis, no red flags
1st line supportive care only — voice rest/reduced voice use, hydration, humidification, and avoidance of irritants (see Non-Pharmacologic Treatment); expect gradual improvement over 1-2 weeks.[1] Do not use antibiotics — acute laryngitis is a viral illness, and the modest, inconsistent subjective benefits reported for some antibiotics in trials do not outweigh the cost, adverse effects, and antimicrobial-resistance implications of routine use.[2] Do not use corticosteroids before the larynx has been visualized — current guidance recommends against prescribing corticosteroids for dysphonia prior to laryngoscopy, given limited demonstrated benefit and real potential harm.[1]
Suspected bacterial superinfection (genuinely uncommon)
Special situation a short antibiotic course (see Drug Tables) only for features that actually suggest bacterial superinfection — worsening after an initial period of improvement, high fever, purulent findings, or marked systemic illness — not for typical, self-limited viral laryngitis.[2]
Suspected reflux (LPR) laryngitis
1st line reflux-directed lifestyle and dietary modification (see Non-Pharmacologic Treatment) for every patient with a history suggestive of LPR. If lifestyle measures alone are insufficient, or reflux symptoms are prominent a twice-daily proton pump inhibitor trial for 8-12 weeks is reasonable — but set expectations honestly: placebo-controlled trials of empiric PPI therapy for isolated laryngeal symptoms without confirmed reflux have shown inconsistent, often minimal benefit over placebo, so this is a genuine therapeutic trial to be reassessed on its own merits, not a guaranteed fix.[3] Adjunct an alginate-based reflux suppressant after meals and at bedtime is a reasonable add-on, particularly for nocturnal or morning-predominant symptoms.
Suspected fungal (candida) laryngitis
Refer first laryngoscopic confirmation before treating — this is not an empiric self-care diagnosis. Correct any inhaled-corticosteroid technique/rinsing issue and address immunocompromise or glycemic control where relevant; antifungal therapy (see Drug Tables) is directed by the confirming clinician.
Chronic phonotraumatic laryngitis / vocal fold nodules or polyps / Reinke's edema
1st line voice therapy with a speech-language pathologist and, for Reinke's edema, smoking cessation — not medication. Refer for laryngoscopy first per the 4-week/red-flag rule above; medication does not treat a structural phonotraumatic lesion.
Any red flag, at any point
Stop self-care refer per Red Flags & Refer instead of continuing or escalating an empiric trial.
Non-Pharmacologic Treatment
Vocal hygiene (every patient)
- Relative voice rest — reduce voice use, avoid shouting, cheering, or straining to be heard over background noise; complete voice rest is rarely practical or necessary, but professional voice users with a significant vocal demand should genuinely reduce or pause use where possible.[1]
- Do not whisper as a substitute for resting the voice — whispering can increase laryngeal muscle tension and strain more than soft, normal ("confidential") speech; teach this distinction explicitly.
- Adequate systemic hydration (water, not just local throat soothing) and use of a humidifier, particularly in dry indoor air.
- Avoid or reduce caffeine and alcohol, both of which have a diuretic/drying effect on the airway mucosa.
- Avoid smoking and vaping, and secondhand smoke exposure; see the Tobacco Use Disorder chapter for the full cessation approach.
- Avoid known irritant and allergen exposures where identifiable; treat concurrent allergic rhinitis (see the Allergic Rhinitis chapter).
- Warm up the voice before sustained heavy use (singers, public speakers) and use amplification where available rather than projecting over noise or distance.
Reflux-directed lifestyle measures (suspected LPR)
- Avoid eating within roughly 3 hours of lying down or going to bed.
- Smaller, more frequent meals rather than large meals.
- Elevate the head of the bed for patients with nocturnal or morning-predominant symptoms.
- Identify and reduce individual trigger foods/beverages where the patient recognizes a pattern (common examples: caffeine, alcohol, carbonated beverages, high-fat or spicy foods, chocolate, citrus) — evidence for any single universal dietary restriction is limited, so individualize rather than imposing a rigid list.[3]
- Weight loss where clinically appropriate for an overweight patient.
- Smoking cessation — an independent reflux and laryngeal-irritant contributor.
Referral for voice therapy
Speech-language pathology-directed voice therapy is the primary, non-pharmacologic treatment for phonotraumatic laryngitis, muscle tension dysphonia, and vocal fold nodules — refer after, not instead of, the laryngoscopy that confirms the diagnosis and rules out a different structural cause.
Special Populations
Pregnancy
Voice rest, hydration, and reflux-directed lifestyle measures are unrestricted and first-line throughout pregnancy. Acetaminophen is the preferred analgesic; use ibuprofen cautiously and avoid it in the third trimester per standard NSAID-in-pregnancy precautions. Proton pump inhibitors (omeprazole, pantoprazole) are generally considered compatible with pregnancy when reflux symptoms genuinely warrant treatment. Avoid unnecessary corticosteroid courses; reserve for a specifically indicated, specialist-directed situation. Dextromethorphan and guaifenesin have generally reassuring safety data at usual doses but should still be used only when genuinely needed rather than routinely.
Breastfeeding
Acetaminophen and ibuprofen are both compatible. Proton pump inhibitors are considered compatible given minimal milk transfer. Antibiotics used for a genuine bacterial superinfection should follow standard breastfeeding-compatible selection — amoxicillin/clavulanate and azithromycin are both reasonable.
Pediatrics
Isolated "laryngitis" in a young child needs to be distinguished from croup (viral laryngotracheitis), which presents with a barky cough, hoarse voice, and inspiratory stridor, typically in children 6 months to 3 years, worsens at night, and is managed with a single dose of oral dexamethasone (0.6 mg/kg) plus nebulized epinephrine for moderate-to-severe cases — a genuinely different, specifically pediatric management pathway from the adult approach in this chapter.[5] Croup itself has to be distinguished from its own more dangerous mimics — epiglottitis (absent barky cough, high fever, drooling, toxic appearance), bacterial tracheitis (high fever, poor response to epinephrine), retropharyngeal abscess (neck pain, dysphagia, torticollis), and foreign body aspiration (a choking history, biphasic stridor, asymmetric air entry) — recognizing these mimics, not just treating presumed croup, is the point of a careful pediatric assessment.[5][4] Recurrent or progressive hoarseness and stridor in a child should raise suspicion for recurrent respiratory papillomatosis and prompt pediatric ENT referral rather than repeated presumptive treatment for viral laryngitis or croup.
Older adults
Persistent hoarseness carries a higher baseline likelihood of malignancy in this group — apply the 4-week/red-flag laryngoscopy threshold without a higher bar for "probably nothing." Consider presbylaryngis (age-related vocal fold atrophy producing a weak, breathy voice without an acute inflammatory trigger) as a genuine, non-infectious explanation for gradual voice change, distinct from laryngitis, once other causes are excluded on laryngoscopy. Anticholinergic-heavy medication regimens can worsen laryngeal dryness and irritation — review the medication list where hoarseness is persistent.
Immunocompromised patients
Maintain a lower threshold for laryngoscopic evaluation and specialist referral; candida laryngitis, atypical infections, and a generally more severe or prolonged course are all more likely in this group.
Professional voice users
Apply the "professional voice user" criterion for expedited, rather than 4-week-delayed, laryngoscopy literally — this group's livelihood depends on a specific, testable functional outcome, and early laryngoscopy avoids both missing a structural lesion and unnecessary time off voice use.[1] Discuss the limited and largely unproven benefit, alongside the real risks, of a short corticosteroid course used specifically to get through an imminent, essential performance — this is a genuine, case-by-case discussion after laryngoscopy confirms it is safe to do so, not a routine option.[1] Early referral to voice therapy is appropriate for any recurrent or persistent phonotraumatic pattern.
Renal and hepatic impairment
Adjust or avoid acetaminophen dosing in significant hepatic impairment. Avoid or dose-adjust ibuprofen in significant renal impairment. Dose-adjust antibiotics per standard renal/hepatic references where relevant; fluconazole requires renal dose adjustment.
Monitoring & Follow-Up
For uncomplicated acute viral laryngitis, expect gradual improvement over 1-2 weeks; advise the patient to return, rather than continue self-care, if the voice has not meaningfully improved by 3 weeks — this positions the patient to meet the formal 4-week laryngoscopy threshold without unnecessary delay.[1]
- For a bacterial-superinfection antibiotic trial, reassess at completion — persistent symptoms should prompt reconsidering the diagnosis and pursuing laryngoscopy rather than a repeat or extended antibiotic course.
- For a reflux (LPR) PPI trial, reassess at 8-12 weeks; genuine improvement supports continuing at the lowest effective dose or a defined taper trial, while no improvement should prompt reconsidering the diagnosis — including confirming adherence to the concurrent lifestyle measures — rather than simply extending the trial indefinitely.[3]
- For candida laryngitis, confirm resolution and correct the underlying contributor (inhaled corticosteroid technique/rinsing, glycemic control, immunosuppression review) to reduce recurrence.
- For phonotraumatic laryngitis/vocal fold nodules referred for voice therapy, adherence and progress are tracked by the treating speech-language pathologist and ENT, typically with interval laryngoscopy.
- Reinforce the red-flag return criteria explicitly at every visit, given how infrequent but consequential they are: new stridor or breathing difficulty, hemoptysis, dysphagia/odynophagia progression, or hoarseness that has still not resolved by 4 weeks.
Common Errors to Avoid
- Prescribing antibiotics reflexively for acute laryngitis, which is overwhelmingly a viral illness.
- Prescribing or continuing corticosteroids for dysphonia before the larynx has actually been visualized.
- Recommending empiric antireflux medication for isolated hoarseness without any reflux-type symptoms, and without setting honest expectations about the modest, inconsistent trial evidence for empiric PPI therapy in LPR.
- Letting a course of empiric self-care or medication quietly extend past the 4-week laryngoscopy threshold instead of referring on time.
- Missing the "regardless of duration" red-flag list — recent head/neck/chest surgery or intubation, a neck mass, tobacco history, professional voice user status, respiratory distress — these override the 4-week rule and need prompt, not delayed, laryngoscopy.
- Recommending whispering as "resting the voice" — it typically increases laryngeal strain rather than reducing it.
- Mistaking early epiglottitis/supraglottitis for ordinary severe laryngitis, or attempting an oropharyngeal exam with a tongue depressor in a child with suspected epiglottitis.
- Overlooking referred otalgia, unexplained weight loss, or hemoptysis as the red flags they are.
- Treating gradual, age-related presbylaryngis in an older adult as ordinary infectious laryngitis without considering the alternative diagnosis once other causes are excluded.
- Assuming a chronically hoarse child has recurrent croup or laryngitis without considering recurrent respiratory papillomatosis.
- Diagnosing or treating candida laryngitis empirically without laryngoscopic confirmation.
- Treating vocal fold nodules, polyps, or Reinke's edema as a medication-responsive problem rather than referring for voice therapy and, for Reinke's edema, smoking cessation.
Clinical Decision Algorithm
Drug Tables
How to use this table: Doses are adult doses and require patient-specific confirmation (renal/hepatic function, weight, allergy history). Pediatric dosing is weight-based per the current product monograph unless stated. Drug pricing is intentionally omitted. Select any drug name to open its complete Pharmasist Drug Database page.
Analgesic and Symptomatic Cough Adjuncts
Adjunctive only — none of these treat the laryngitis itself. Persistent symptoms despite adequate use need reassessment, not escalating adjunct therapy.
| Drug | Dosage | Adverse effects | Drug interactions | Comments |
|---|---|---|---|---|
| Acetaminophen | Adults: 325-650 mg PO Q4-6H PRN, per product labelling | Hepatotoxicity with overdose or significant hepatic impairment | None significant at standard doses | First-line analgesic for sore throat/odynophonia. |
| Ibuprofen | Adults: 200-400 mg PO Q6-8H PRN with food, max 1200 mg/day OTC | GI upset; renal impairment with prolonged use | Increased bleeding risk with anticoagulants; avoid with other NSAIDs | Reasonable alternative if acetaminophen is insufficient or not appropriate. |
| Dextromethorphan | Adults: 10-20 mg PO Q4H PRN, or 30 mg Q6-8H PRN, max 120 mg/day | Drowsiness, dizziness | Serotonergic risk with MAOIs and certain antidepressants (serotonin syndrome) | For a bothersome dry cough specifically — not the hoarseness itself. |
| Guaifenesin | Adults: 200-400 mg PO Q4H PRN (immediate-release), max 2400 mg/day | GI upset | None significant | Weak evidence specific to laryngitis; adequate systemic hydration matters at least as much. |
Antireflux Therapy — Confirmed or Strongly Suspected LPR
Reserve for a history genuinely suggestive of laryngopharyngeal reflux, alongside lifestyle measures — not a default therapy for isolated hoarseness. Evidence for empiric PPI benefit in unselected patients is inconsistent.
| Drug | Dosage | Adverse effects | Drug interactions | Comments |
|---|---|---|---|---|
| Pantoprazole | Adults: 40 mg PO BID for 8-12 weeks | Headache, GI upset; long-term risk (B12/magnesium deficiency, fracture) with prolonged use | Reduces absorption of drugs requiring an acidic environment (e.g., certain azole antifungals) | 8-12 week trial, then reassess; taper rather than stopping abruptly after prolonged use. |
| Omeprazole | Adults: 20 mg PO BID for 8-12 weeks | Headache, GI upset; long-term risk (B12/magnesium deficiency, fracture) with prolonged use | Reduces clopidogrel activation; reduces absorption of drugs requiring an acidic environment | Equivalent alternative to pantoprazole within the class. |
| Alginate / magnesium carbonate | Adults: 10-20 mL PO after meals and at bedtime | Generally well tolerated; mild GI upset | May reduce absorption of some concurrently administered oral drugs — separate dosing | Adjunct raft therapy for nocturnal/postprandial symptoms; add to, not substitute for, a PPI trial or lifestyle measures. |
Antibiotics — Confirmed Bacterial Superinfection Only
Not indicated for typical, self-limited viral laryngitis. Reserve for features genuinely suggesting bacterial superinfection (worsening after initial improvement, high fever, purulent findings, marked systemic illness).
| Drug | Dosage | Adverse effects | Drug interactions | Comments |
|---|---|---|---|---|
| Amoxicillin/clavulanate | Adults: 875 mg PO BID x 7-10 days | Nausea, vomiting, hypersensitivity; diarrhea more common than amoxicillin alone | May increase methotrexate levels; may increase INR with warfarin | Reasonable first choice when bacterial superinfection is genuinely suspected. |
| Azithromycin | Adults: 500 mg PO day 1, then 250 mg PO daily days 2-5 | GI upset, QT prolongation | Increases levels of several CYP3A4 substrates; additive QT risk with other QT-prolonging drugs | Reasonable alternative for a true penicillin allergy. |
Antifungals — Laryngoscopically Confirmed Candida Laryngitis Only
Not an empiric self-care diagnosis or treatment — confirm on laryngoscopy first and correct the underlying contributor (inhaled corticosteroid technique/rinsing, glycemic control, immunosuppression).
| Drug | Dosage | Adverse effects | Drug interactions | Comments |
|---|---|---|---|---|
| Fluconazole | Adults: 100-200 mg PO once daily for 14-21 days | Hepatotoxicity, QT prolongation | Numerous CYP2C9/CYP3A4-mediated interactions (e.g., warfarin, statins, sulfonylureas) — review the full medication list | Specialist-directed; renal dose adjustment required. |
Oral Corticosteroids — Not Routine Therapy
Current guidance recommends against prescribing corticosteroids for dysphonia before the larynx has been visualized. A short course is considered only case-by-case, after laryngoscopy, for a genuinely urgent professional-voice need — discussed explicitly with the patient, including the limited evidence of benefit and the real risks.
| Drug | Dosage | Adverse effects | Drug interactions | Comments |
|---|---|---|---|---|
| Dexamethasone | Adults: No default dose — case-by-case, post-laryngoscopy, specialist-directed only | Hyperglycemia, insomnia, mood change, GI upset; adrenal suppression with repeated use | Increased hyperglycemia risk with other glucose-elevating drugs; may reduce vaccine response | Not a default or repeated therapy — reassess the need for laryngoscopy/voice therapy rather than repeating a course. |
