What Does Imiquimod Treatment Treat?

Imiquimod is a topical medicine that activates an immune response in treated skin. Clinicians may prescribe it for certain [Actinic Keratosis](/conditions/actinic-keratosis/), selected superficial [Basal Cell Carcinoma](/conditions/basal-cell-carcinoma/), and external [Genital Warts](/conditions/genital-warts/). Some ordinary [Warts](/conditions/warts/) may also be treated, depending on their site and type.

The cream is applied only to the area and schedule prescribed. Redness, swelling, scaling, crusting, soreness, or itching can occur as the skin reacts. This response does not by itself show whether a lesion has cleared, so follow-up matters. A clinician may need to examine or sample a suspicious lesion before choosing [Imiquimod](/materials/imiquimod/).

Use the prescribed amount and frequency, wash hands after application, and keep the cream away from eyes, lips, and broken skin unless specifically instructed. Do not cover the area with an occlusive dressing or add other products without checking first. Protect treated skin from unnecessary sun exposure and attend the planned review.

Ask what to do if the reaction becomes difficult to tolerate or a dose is missed. For some lesions, [Cryotherapy (Lesion Removal)](/treatments/surgical-dermatology/cryotherapy-lesion-removal/) may be considered instead. The choice depends on lesion type, depth, location, immune status, and previous treatment.

Contact the prescriber if severe pain, extensive blistering, spreading swelling, pus, fever, or a reaction outside the treated area develops. Seek urgent help for facial swelling, breathing difficulty, or a severe allergic reaction. A lesion that bleeds repeatedly, grows, changes, or fails to heal needs reassessment rather than repeated self-treatment.

What lesion are we treating, and how was it diagnosed? Which areas should receive cream? What reaction is expected, and when should I pause or call? How will you confirm the lesion has responded? What alternatives are appropriate for its location?
