Aldara : Uses, Side Effects, Interactions & More

Why is this medication prescribed?

Aldara (Imiquimod) cream is used to treat certain types of actinic keratoses (flat, scaly growths on the skin caused by too much sun exposure) on the face or scalp. Aldara cream is also used to treat superficial basal cell carcinoma (a type of skin cancer) on the trunk, neck, arms, hands, legs, or feet and warts on the skin of the genital areas and anal. Aldara is in a class of medications called immune response modifiers. Treats genital and anal warts by increasing the activity of the body’s immune system. It is not known exactly how Aldara cream works to treat actinic keratosis or superficial basal cell carcinoma.

Aldara cream does not cure warts and new warts may appear during treatment. It is not known if Aldara cream prevents the spread of warts to other people.

How should this medicine be used?

Aldara (Imiquimod) comes as a cream to apply to the skin.

If you are using Aldara cream to treat actinic keratosis, you will probably apply it once a day for 2 days a week, 3 to 4 days apart (for example, Monday and Thursday or Tuesday and Friday). Do not apply the cream to an area larger than your forehead or cheek (approximately 2 inches by 2 inches). Aldara cream should be left on the skin for about 8 hours. Continue to use Aldara cream for a full 16 weeks, even if all actinic keratoses have cleared, unless your doctor tells you otherwise.

If you are using Aldara cream to treat superficial basal cell carcinoma, you will probably apply it once a day for 5 days a week (for example, Monday through Friday). Apply the cream to the basal cell carcinoma and the immediate surrounding area. Aldara cream should be left on the skin for about 8 hours. Continue using Aldara for a full 6 weeks, even if the superficial basal cell carcinoma seems to have disappeared, unless your doctor tells you otherwise.

If you are using Aldara cream to treat genital and anal warts, you will probably apply it once a day for 3 days a week (for example, Monday, Wednesday, and Friday or Tuesday, Thursday, and Saturday). Aldara cream should be left on the skin for 6 to 10 hours. Continue using Aldara until all warts have healed, up to a maximum of 16 weeks.

Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Use Aldara exactly as directed. Do not use more or less or use it more often than prescribed by your doctor.

Do not cover the treated area with a tight bandage or dressing unless directed by your doctor. Cotton gauze dressings can be used if necessary. Cotton underwear can be worn after treating the genital or anal areas.

If you are using Aldara cream to treat genital or anal warts, you should avoid sexual contact (oral, anal, genital) while the cream is on your skin. Aldara cream can weaken condoms and vaginal diaphragms.

Uncircumcised men who are treating warts under the foreskin of the penis should pull the foreskin back and clean it every day and before each treatment.

Aldara cream is for use on the skin only. Do not apply Aldara cream in or near your eyes, lips, nostrils, vagina, or anus. If Aldara cream gets into your mouth or eyes, rinse well with water right away.

Aldara cream comes in single-use packets. Discard opened packages if you don’t use all of the cream.

To use the cream, follow these steps:

  1. Wash your hands.
  2. Wash the area to be treated with mild soap and water and allow it to dry.
  3. Apply a thin layer of cream to the area to be treated, just before going to sleep.
  4. Rub the cream on the skin until it disappears.
  5. Wash your hands.
  6. Leave the cream on the area for as long as your doctor has told you to. Do not bathe, shower, or swim during this time.
  7. After the treatment time is over, wash the area with mild soap and water to remove the cream.
