Nizoral is used for treating fungal infections. Nizoral is an azole antifungal. It kills sensitive fungi by interfering with the formation of the fungal cell membrane.
Use Nizoral as directed by your doctor!
- 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 H2antagonist (eg, famotidine), or a proton pump inhibitor (eg, omeprazole), take Nizoral at least 2 hours before the H2antagonist, 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.
- 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.
Ask your health care provider any questions you may have about how to use Nizoral.
Store Nizoral between 59 and 77 degrees F (15 and 25 degrees C). Store away from heat, moisture, and light. Do not store in the bathroom. Keep Nizoral out of the reach of children and away from pets.

Important safety information:
- Nizoral may cause dizziness or drowsiness. These effects may be worse if you take it with alcohol or certain medicines. Use Nizoral with caution. Do not drive or perform other possible unsafe tasks until you know how you react to it.
- Rarely, Nizoral may cause a severe allergic reaction right after you take the first dose. Symptoms may include difficulty breathing; tightness in the chest; swelling of the eyelids, face, or lips; or rash or hives. If this happens, seek medical care at once.
- Use of alcohol with Nizoral has rarely caused symptoms such as flushing, rash, swelling of the hands and feet, nausea, and headache. Talk with your doctor before drinking alcohol while taking Nizoral.
- Do NOT take more than the recommended dose or use for longer than prescribed without checking with your doctor.
- Nizoral only works against fungi; it does not treat viral infections (eg, the common cold) or bacterial infections.
- Be sure to use Nizoral for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The infection could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
- Diabetes patients - Nizoral may increase the risk of low blood sugar from your diabetes medicine. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Hormonal birth control (eg, birth control pills) may not work as well while you are using Nizoral. To prevent pregnancy, use an extra form of birth control (eg, condoms).

- Nizoral should be used with extreme caution in children; safety and effectiveness in children have not been confirmed.
- Pregnancy and breast-feeding: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Nizoral while you are pregnant. Nizoral is found in breast milk. Do not breastfeed while using Nizoral.
