Summary
Imiquimod is used to treat skin conditions like actinic keratosis, which are rough, scaly patches on the skin caused by sun damage, superficial basal cell carcinoma, which is a type of skin cancer, and genital warts, which are growths caused by certain types of human papillomavirus (HPV).
Imiquimod works by stimulating the immune system, which is the body's defense system against infections and diseases. It activates immune cells in the skin to attack abnormal cells or viruses causing the condition, helping to clear up lesions or warts.
Imiquimod is applied as a cream directly to the affected skin area. The usual dose for adults is a thin layer applied once daily, typically at bedtime. The frequency and duration depend on the condition being treated, so always follow your doctor's instructions.
Common side effects of imiquimod include redness, itching, and burning at the application site. These effects are usually mild and temporary. If you notice any new or worsening symptoms, contact your doctor for advice.
Imiquimod should not be used on broken or inflamed skin. Avoid use if allergic to its ingredients. It's not recommended for people with autoimmune disorders, which are conditions where the immune system attacks the body. Pregnant or breastfeeding women should consult their doctor before use.
