Nizoral (ketoconazole) is applied topically to address fungal skin conditions within the dermatological infection spectrum. - Seborrheic dermatitis: reduces inflammation and flaking caused by Malassezia yeast. - Dandruff (pityriasis capitis): controls scalp scaling and itching. - Tinea corporis: clears body ringworm lesions. - Tinea cruris: treats groin fungal infection. - Tinea versicolor: eliminates pigment‑changing yeast overgrowth.

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

Common Side Effects: - Burning or stinging sensation at the application site. - Itching (pruritus) of the treated area. - Redness or erythema. - Dryness or flaking of skin. - Contact dermatitis.

Serious or Rare Side Effects: - Severe allergic reaction (angioedema, anaphylaxis). - Hepatotoxicity (rare with extensive use). - Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Significant skin discoloration. - Systemic absorption leading to endocrine effects (e.g., gynecomastia) – extremely rare.

Before using Nizoral, consider the following safety measures. - Assess skin integrity: avoid application on broken or inflamed skin. - Review medical history: caution in patients with known liver disease. - Pregnancy and lactation: consult a healthcare professional before use. - Concomitant topical agents: do not combine with other irritating products. - Allergic reactions: discontinue if signs of hypersensitivity appear. - Store at room temperature: keep in original container, protect from moisture and direct sunlight.

Ketoconazole can interact with other medicines, primarily through inhibition of hepatic enzymes.

Major Interactions (Avoid): - Systemic azole antifungals: increased risk of cumulative toxicity. - Warfarin: potentiation of anticoagulant effect. - Cyclosporine: elevated blood levels leading to nephrotoxicity.

Moderate Interactions (Monitor Closely): - Oral contraceptives: possible reduction in efficacy. - Antihistamines: may increase sedation. - Topical corticosteroids: enhanced skin irritation.
