Nizoral (Ketoconazole)

Nizoral is used for treating fungal infections. It may also be used for other conditions as determined by your doctor.

Use Nizoral as directed by your doctor. Check the label on the medicine for exact dosing instructions.

Take Nizoral by mouth with or without food.

Do not take an antacid within 1 hour before or 2 hours after you take Nizoral . If you are also taking an anticholinergic (eg, hyoscyamine), an H2 antagonist (eg, famotidine), or a proton pump inhibitor (eg, omeprazole), take Nizoral at least 2 hours before the H2 antagonist, proton pump inhibitor, or anticholinergic.

To clear up your infection completely, take Nizoral for the full course of treatment. Keep taking it even if you feel better in a few days.

Nizoral works best if it is taken at the same time each day.

Nizoral is an azole antifungal. It kills sensitive fungi by interfering with the formation of the fungal cell membrane.

If you miss a dose of Nizoral , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Nizoral tablets: store at 59-86degrees F, protect from moisture. Nizoral shampoo: store at a temperature not above 77 degrees F, protect from light.

Do NOT use Nizoral if:

• you are allergic to any ingredient in Nizoral
• you have a fungal infection in the brain membranes (fungal meningitis)
• you are taking an aldosterone blocker (eg, eplerenone), astemizole, cisapride, conivaptan, dofetilide, an ergot alkaloid (eg, ergotamine), erythromycin, midazolam, nevirapine, pimozide, a quinazoline (eg, alfuzosin), quinidine, rifabutin, rifampin, terfenadine, triazolam, or a 5-HT receptor agonist (eg, eletriptan)

• if you are pregnant, planning to become pregnant, or are breast-feeding
• if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
• if you have allergies to medicines, foods, or other substances

• Nevirapine, rifabutin, or rifampin because they may decrease Nizoral 's effectiveness
• Astemizole, cisapride, dofetilide, erythromycin, pimozide,quinidine, or terfenadine because the risk of severe heart effects may be increased
• Midazolam or triazolam because their actions and the risk of their side effects may be increased by Nizoral , resulting in increased risk of sedation and breathing difficulties
• Aldosterone blockers (eg, eplerenone), conivaptan, ergot alkaloids (eg, ergotamine), quinazolines (eg, alfuzosin) or 5-HT receptor agonists (eg, eletriptan) because the risk of their side effects may be increased by Nizoral
