How does this medication work? What will it do for me?

Ketoconazole belongs to the family of medications called antifungals. It is used to treat fungal infections of the skin (ringworm, athlete's foot, and jock itch) and nails. It is also used to treat "sun fungus" (tinea versicolor, pityriasis versicolor).

The shampoo is used to treat and prevent conditions such as dandruff and seborrheic dermatitis. Ketoconazole works by preventing the fungus from making normal cell walls, thereby stopping fungal growth.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.

How should I use this medication?

Ketoconazole shampoo: Apply 5 mL to 10 mL to the wet scalp, work into a lather, and leave on for 3 to 5 minutes before rinsing with water. Take care to keep the shampoo out of the eyes and off the eyelids. If contact occurs, flush the eyes thoroughly with water. If using as a treatment, apply twice weekly for 2 to 4 weeks. If using as a preventative measure, apply once every 1 to 2 weeks.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.

Ketoconazole should be used for the recommended duration of treatment, even if the symptoms seem to have disappeared. This will reduce the chance of the fungal infection returning.

It is important to use medication exactly as prescribed by your doctor. If you miss a dose, use it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not apply a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature, do not allow it to freeze, and keep it out of reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Allergy: If a reaction suggesting allergy or chemical irritation should occur, stop using ketoconazole cream or shampoo and contact your doctor. Signs of an allergic reaction may include itchiness, rash, or swelling of the affected area.

What other drugs could interact with this medication?

Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them. Depending on your specific circumstances, your doctor may want you to:

• stop taking one of the medications,
• change one of the medications to another,
• change how you are taking one or both of the medications, or
• leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. In many cases, interactions are intended or are managed by close monitoring. Speak to your doctor about how any drug interactions are being managed or should be managed.
