Laryngitis

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).

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

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.

• 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.

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

• 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.

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.

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.

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.

1. Confirm the diagnosis and adherence first: was this genuinely self-limited viral laryngitis, has an adequate trial of voice rest/hydration/humidification actually been followed, and has 3-4 weeks genuinely elapsed — before assuming treatment has "failed."
2. Reconsider the differential (see Assessment & Diagnosis) — reflux, phonotraumatic/structural, allergic/irritant, fungal, and autoimmune causes all need a different specific approach than simply repeating supportive care.
3. If not already met, apply the 4-week laryngoscopy threshold now — refer rather than continuing empiric management further.^[1]
4. For a treated bacterial superinfection with persistent symptoms after a completed course: reconsider the diagnosis and pursue laryngoscopy rather than repeating or broadening antibiotics.
5. For an inadequate response to an 8-12 week PPI trial: confirm adherence to both medication and lifestyle measures, then refer for laryngoscopy and RFS scoring to confirm or exclude LPR as the actual driver, rather than continuing PPI therapy empirically.^[3][7]
6. For persistent hoarseness in a professional voice user or smoker despite initial measures: expedite laryngoscopy and voice therapy referral rather than extending a further trial of self-care.
7. Any red flag emerging at any point in this pathway: stop escalating self-care and refer per Red Flags & Refer instead.

• 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.

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.

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.

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).

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).

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.
