Why is this drug prescribed?
Nizoral, a broad-spectrum antifungal drug available in tablet form, may be given to treat several fungal infections within the body, including oral thrush and candidiasis.
It may also be given to treat severe, hard-to-treat fungal skin infections that have not cleared up after treatment with creams or ointments, or the oral drug griseofulvin (Fulvicin, Grisactin).
Most important fact about this drug
In some people, Nizoral may cause serious or even fatal damage to the liver. Before starting to take Nizoral, and at frequent intervals while you are taking it, you should have blood tests to evaluate your liver function. Tell your doctor immediately if you experience any signs or symptoms that could mean liver damage: these include unusual fatigue, loss of appetite, nausea or vomiting, jaundice, dark urine, or pale stools.
How should you take this medication?
Take Nizoral exactly as prescribed.
You should keep taking the drug until tests show that your fungal infection has subsided. If you stop too soon, the infection might return.
You may want to take Nizoral Tablets with meals to avoid stomach upset.
Avoid alcohol and do not take with antacids. If antacids are necessary, you should wait 2 to 3 hours before taking them.
