Ketoconazole is used topically to treat a range of superficial fungal infections of the skin.

- Tinea corporis: reduces fungal growth and promotes clearance of body ringworm lesions. - Tinea cruris: alleviates itching and eliminates the fungal cause of jock itch. - Tinea pedis: improves foot skin condition by eradicating dermatophyte infection. - Seborrheic dermatitis: controls yeast‑related scalp inflammation and scaling. - Pityriasis versicolor: restores normal skin pigmentation by eliminating Malassezia species.

Topical ketoconazole may cause local skin reactions, ranging from mild irritation to rare severe events.

Common Side Effects: - Itching: mild pruritus at the application site. - Burning sensation: transient heat feeling during or after use. - Redness: localized erythema around the treated area.

Serious or Rare Side Effects: - Allergic reaction: hives, swelling, or breathing difficulty. - Severe skin rash: widespread dermatitis or bullous eruptions. - Hepatic toxicity: rare systemic absorption causing liver enzyme elevation.

When using topical ketoconazole, observe the following precautions to ensure safe and effective treatment.

- Avoid application on broken or inflamed skin: may increase irritation or systemic absorption. - Discontinue if severe irritation occurs: seek medical advice promptly. - Keep away from eyes and mucous membranes: rinse thoroughly if contact happens. - Do not use with other topical antifungals unless directed: risk of additive irritation. - Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Ketoconazole can interact with other medicines, especially when systemic absorption is possible.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin): may increase ketoconazole levels and toxicity. - Oral antifungal agents (e.g., terbinafine): concurrent use can raise risk of liver injury.

Moderate Interactions (Monitor Closely): - Warfarin: ketoconazole may enhance anticoagulant effect, monitor INR. - Hormonal contraceptives: efficacy may be reduced, advise alternative contraception. - Topical steroids: may mask irritation, assess skin response regularly.
