What is the most important information I should know about Nizoral?

Do not take Nizoral if you are taking astemizole (Hismanal), cisapride (Propulsid), triazolam (Halcion) or midazolam (Versed). Combined with these drugs, Nizoral could cause serious, even fatal, side effects.

In rare cases, Nizoral has caused severe liver damage, sometimes resulting in death. Notify your doctor immediately if you develop nausea, vomiting, abdominal pain, unusual fatigue, loss of appetite, yellow skin or eyes, itching, dark urine or clay colored stools. These symptoms may be early signs of liver damage.

Take all of the Nizoral that has been prescribed for you even if you begin to feel better. Your symptoms may begin to improve before the infection is completely treated.
