• Clotrimazole 1% cream is used to treat diaper rash infected with Candida albicans, when diagnosed by a physician.
• Clotrimazole 1% cream is not suitable for treating fungal infections of the nails or scalp.

• There are limited data on clotrimazole use in pregnant women, though animal studies have not shown harmful reproductive effects.
• Use during pregnancy, especially the first trimester or while trying to conceive, is not recommended unless a physician considers it essential.

• Clotrimazole and its breakdown products have been shown to pass into milk in animal studies.
• Breastfeeding should be discontinued during treatment, or use should only be on the advice of a physician, since topical application does still result in some systemic absorption.

• No specific dosing differences have been identified for older adults using topical clotrimazole cream.

• For diaper rash caused by Candida albicans and diagnosed by a physician, the cream may be used in children as directed by a doctor.
• Clotrimazole cream is not recommended for children under 2 years of age unless a doctor advises otherwise.

• For diaper rash in children, a thin layer of cream is applied and gently massaged into the affected and surrounding skin twice daily, morning and evening, at diaper changes, for no more than 14 days.
• For jock itch, athlete's foot, and ringworm in adults, a thin layer of cream is applied and gently massaged into the affected and surrounding skin twice daily, morning and evening.
• Athlete's foot typically requires at least 4 weeks of treatment; jock itch, ringworm, and diaper rash usually resolve within 2-4 weeks; candidiasis is generally treated for 2 weeks.
• Treatment should continue for about 2 weeks after symptoms clear to help prevent relapse, even if improvement occurs sooner.
• If there is no improvement after 4 weeks in adults, or after 14 days for diaper rash, a physician should be consulted.
• If a dose is missed, apply the next dose as scheduled; do not apply extra cream to make up for a missed application.

If overdose is suspected, seek emergency medical attention immediately or contact your regional Poison Control Centre without delay.

• Use with caution around the eyes, since clotrimazole cream is not intended for ophthalmic use; rinse thoroughly with water if accidental eye contact occurs.
• Do not cover the treated area with an occlusive dressing unless directed by a physician, since this can increase irritation; regular diaper use is not considered occlusive.

• Clotrimazole cream may reduce the effectiveness of latex-based contraceptive products, including condoms, diaphragms, and vaginal spermicides; this effect is temporary and limited to the treatment period.

• Food interactions do not apply, since clotrimazole cream is applied to the skin rather than taken by mouth.

• Clotrimazole cream is applied twice daily, morning and evening, rather than timed around meals, since it is a topical product.
