Why is Ketoconazole Cream Prescribed for Groin Itch?
Ketoconazole cream is used to treat tinea corporis (ringworm; fungal skin infection that causes a red scaly rash on different parts of the body), tinea cruris (jock itch; fungal infection of the skin in the groin or buttocks), tinea pedis (athlete's foot; fungal infection of the skin on the feet and between the toes), tinea versicolor (fungal infection that causes brown or light colored spots on the chest, back, arms, legs, or neck), and yeast infections of the skin. Prescription ketoconazole shampoo is used to treat tinea versicolor. Ketoconazole is in a class of antifungal medications called imidazoles. It works by slowing the growth of fungi that cause infection.
How should this Medicine be used?
Prescription ketoconazole comes as a cream and a shampoo to apply to the skin. Ketoconazole cream is usually applied once a day for 2 to 6 weeks. Prescription ketoconazole shampoo is usually applied one time to treat the infection. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use ketoconazole exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
If you are using ketoconazole cream, your symptoms should improve at the beginning of your treatment. Continue to use ketoconazole cream even if you are feeling well. If you stop using ketoconazole cream too soon, your infection may not be completely cured and your symptoms may return.
To use the cream, apply enough cream to cover the affected area and all of the skin around it.
What Special Precautions should I follow?
Before using ketoconazole,
- tell your doctor and pharmacist if you are allergic to ketoconazole or any other medications, creams, or shampoos. If you will be using the cream, tell your doctor if you are allergic to sulfites.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor if you have or have ever had any medical condition. If you will be using the cream, tell your doctor if you have or have ever had asthma.
What special dietary instructions should I follow? Unless your doctor tells you otherwise, continue your normal diet.
What should I do if I forget a dose? Apply the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not apply a double dose to make up for a missed one.
