About Ketydin Soap

Ketydin Soap is primarily used to prevent fungal infections of the skin, like seborrheic dermatitis. Seborrheic dermatitis is a type of dandruff that causes an itchy rash with dry, flaky scales on the skin that contains oil glands, such as the scalp, face, back, and upper chest.

Ketydin Soap contains ketoconazole and zinc pyrithione. It works by causing holes in the fungal cell membrane, which is essential for their survival, as it prevents the entry of unwanted substances into the cells and stops the leakage of cell contents.

Some people may experience itching, redness, irritation or a burning sensation at the application site. Most of these side effects do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

If you are known to be allergic to Ketydin Soap or any other medicines, please tell your doctor. If you are pregnant or a nursing mother, it is advised to consult a doctor before using Ketydin Soap. If you are using any steroidal cream, lotion, or ointment, inform your doctor before using Ketydin Soap. Do not swallow Ketydin Soap. In case of accidental swallowing, contact a nearby poison control centre or consult a doctor immediately.
