How Does It Work?Ketoconazole foam is part of a group of medications known as antifungals. Seborrhea has been linked to certain types of fungus, and ketoconazole foam is thought to work by killing the fungus, although this is not known for sure at this time.
When and How to Use This MedicationSome general considerations to keep in mind during treatment with ketoconazole foam include the following:
- This medication is typically used twice a day for four weeks.
- Turn the canister upside down and dispense into the cap or another cool surface. Dispensing it into a hand is not recommended, as it begins to melt immediately upon contact with warm skin.
- Gently massage the foam into the affected area, picking up only small bits of the foam at once. If your hands are warm, you might want to cool them off by rinsing in cold water and drying beforehand. If the foam still seems runny, try running the can under cold water for a few minutes.
- If you are applying the foam to a hairy area, such as the scalp, part the hair as you go and apply the medication directly to the skin rather than the hair.
- For the medication to work properly, it must be used as prescribed.
