Cautions with other medicines
Only tiny amounts of ketoconazole are absorbed into your body when you use it as a cream or shampoo. You can usually use ketoconazole skin treatments while taking most medicines.
Using ketoconazole with other skin treatments
If you're using a mild steroid cream (such as hydrocortisone) to help with swelling or inflammation caused by the skin infection, put the steroid cream on in the morning and the put the ketoconazole cream on in the evening.
If you're using ketoconazole twice a day, make sure you wait at least 30 minutes after putting it on before using the steroid cream.
Mixing ketoconazole with herbal remedies and supplements
There's not enough information to say that complementary medicines and herbal remedies are safe to take with ketoconazole. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
Important: Medicine safety
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
