Nizoral : Dosage, Precautions Side EffectsWhen it comes to choosing one of the most well-rounded yeast infection treatments on the market, you may want to look into the many uses of Nizoral. From treating fungal skin rashes to eliminating yeast attacks of the lungs and bladder, Nizoral allows consumers to explore the many application options available with this multi-faceted prescription drug. When taking the oral form of Nizoral, you should not take a liquid or tablet form of antacid close to treatment time. This is because the absorption of the medication is affected by the administration of an antacid. If you are known to have an allergy towards sulfites, Nizoral may not be for you. If you are taking additional medication, such as cisapride, astemizole, terfenadine, you may experience heart problems when using Nizoral.
