Nizol 200 tablets should only be used when other antifungal therapy is not available or tolerated. Your doctor may prescribe this antifungal medication only when the potential benefits are considered to outweigh the potential risks. The tablet contains ketoconazole that is used to treat fungal infections.

Each Nizol tablets contain 200 mg of Ketoconazole. The dose usually depends on the type of infection that is being treated. Your doctor may ask to take one tablet a day. You may take this 200 mg tablet with a meal. Do not take an antacid simultaneously since an acid environment in the stomach is required for Nizol to be well absorbed into the body. If you need to take an antacid, then consider taking it an hour before or two hours after the ketoconazole is used. If you are already using anti-ulcer medications that can reduce the acidity of the stomach, absorption may be improved by taking ketoconazole with carbonated cola or cranberry juice. Take the antifungal drug for the duration of time it is prescribed. If you discontinue treatment too early, your infection may return. If your infection worsens or persist, talk to your doctor.
