Ketoconazole can cause serious (possibly fatal) side effects and drug interactions. It should only be used when other treatments have not worked, are not available, or cannot be taken by you. Discuss the risks and benefits of this medication, as well as other effective and possibly safer treatments for fungal infections, with your doctor.

Ketoconazole has rarely caused very serious (possibly fatal) liver problems. Get medical help right away if you develop symptoms of liver problems, including nausea/vomiting that doesn't stop, stomach/abdominal pain, dark urine, yellowing eyes/skin, loss of appetite, or light colored stools. To reduce your risk for liver problems, your doctor should obtain liver function tests every week while you are taking this medication. Do not drink alcoholic beverages while taking ketoconazole because alcohol increases the risk of serious liver problems. See also Notes section.

Ketoconazole must not be used with certain other medications because a serious, possibly fatal, drug interaction may occur. Ketoconazole interacts with drugs such as disopyramide, dofetilide, dronedarone, methadone, pimozide, quinidine, ranolazine, among others. These interactions may increase the risk of a certain condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away. Tell your doctor and pharmacist about all the medications and products you may be taking before you start ketoconazole treatment. See also Precautions section.

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional.

Wet hair and scalp completely with water. Apply enough shampoo to produce enough lather to clean hair and scalp. Massage gently over entire scalp. Rinse hair with warm water. Repeat this process if directed to do so by your doctor. Dry hair thoroughly after the final rinse.

If using the over-the-counter strength of the shampoo (1%), apply the shampoo, lather, and rinse thoroughly. Repeat this process. Dry hair thoroughly after the second rinse.

If treating skin other than the scalp, wet the skin and apply the shampoo to affected area and the surrounding healthy skin. Lather and leave in place for 5 minutes, then rinse off with water.

The dosage, number of applications, and the length of treatment depends on the strength of the shampoo (2% or 1%) and the condition being treated. Carefully follow your doctor's instructions or the package directions.

Avoid contact with the eyes. If the shampoo gets into the eyes, rinse thoroughly with water.

Do not begin using the shampoo if your scalp/skin is broken or swollen.
