Question 3

How does Imiquimod work?

Accepted Answer

Mechanism of Action

Imiquimod is classified as an immune response modifier. Unlike many other topical treatments, it does not directly kill viruses or destroy cancer cells. Instead, it works by stimulating the body's own immune system to attack the skin condition being treated.

When the medication is applied to the skin, it triggers the production of natural substances called cytokines, such as interferon. These substances are part of the body's signaling system that helps regulate immune responses. By increasing these signals locally, imiquimod encourages the immune system to recognize and eliminate abnormal cells or the virus that causes certain types of warts.

The exact mechanism of how imiquimod works for all its approved uses is not completely understood. However, research indicates that it activates specific receptors in the immune system, which then leads to the destruction of targeted skin lesions.

Question 8

What is the dosage of Imiquimod and how do I take it?

Accepted Answer

How to Apply

Before applying the cream, wash your hands and the treatment area with mild soap and water. Allow the skin to dry completely. Apply a thin layer of the cream to the affected area and rub it in gently until it is no longer visible. Wash your hands thoroughly after application.

Application Schedule

Imiquimod is typically used several times per week. The exact schedule depends on the condition being treated. It is usually applied just before going to sleep and should remain on the skin for the recommended amount of time, such as overnight. After this period, the cream must be washed off with mild soap and water.

Do not cover the treated area with airtight bandages or waterproof dressings. You may use breathable cotton gauze if necessary.

Avoid getting the cream in your eyes, nose, mouth, or on your lips.

Do not use the cream inside the vagina or anus.

Use a new packet or measured amount for each application. Do not reuse opened packets.

Missed Dose

If you miss a dose, apply it as soon as you remember. However, if it is almost time for your next scheduled application, skip the missed dose and continue with your regular routine. Do not apply extra cream to make up for a missed dose.

Question 9

Is Imiquimod safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There are no adequate and well-controlled studies of imiquimod use in pregnant women. In animal studies where imiquimod was administered orally at high doses, some evidence of developmental toxicity was observed. However, the amount of medication absorbed through the skin in humans is generally much lower than the doses used in these animal studies. Because animal studies are not always predictive of human response, imiquimod should be used during pregnancy only if clearly needed and after consultation with a healthcare provider.

Breastfeeding

It is not known whether imiquimod is excreted in human milk following topical application. Because many drugs can be passed to an infant through breast milk, healthcare providers recommend exercising caution when using imiquimod cream while nursing. It is important to discuss the potential risks and benefits with a doctor before using this medication if you are breastfeeding.

Question 10

What forms and strengths does Imiquimod come in?

Accepted Answer

Topical Cream

Imiquimod is available as a cream for application to the skin. It is commonly found in the following strengths:

2.5%

3.75%

5%

The medication is typically packaged in single-use packets or multi-dose pump bottles. Single-use packets are designed to be used once and then discarded, even if some cream remains. Pump bottles dispense a specific amount of medication with each use.

Question 11

What is the FDA approval status of Imiquimod?

Accepted Answer

FDA Approval Status

Imiquimod was first approved by the U.S. Food and Drug Administration (FDA) in 1997. It is classified as an immune response modifier and is available by prescription only.

Approved Indications

The FDA has approved imiquimod for the treatment of the following conditions:

Actinic Keratoses: Treatment of clinically typical, nonhyperkeratotic, nonhypertrophic actinic keratoses on the face or scalp in immunocompetent adults.

Superficial Basal Cell Carcinoma: Treatment of biopsy-confirmed, primary superficial basal cell carcinoma in immunocompetent adults when surgical methods are less appropriate.

External Genital and Perianal Warts: Treatment of external genital and perianal warts (condyloma acuminata) in patients 12 years of age and older.

Safety and Regulatory Oversight

There are currently no FDA boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) associated with imiquimod. Regulatory approval is specific to the concentration of the cream and the specific condition being treated. It is not approved for use inside the vagina, anus, or urethra.

Question 12

What should I know about Imiquimod and cream?

Accepted Answer

Uses and Application

Imiquimod cream is primarily prescribed for the treatment of actinic keratoses on the face or scalp, superficial basal cell carcinoma when surgery is not appropriate, and external genital or perianal warts. It works as an immune response modifier, helping the body recognize and fight specific skin issues.

The cream is applied directly to the affected area, typically before bedtime. The frequency of application varies based on the condition being treated:

For actinic keratosis, it is usually applied twice a week for 16 weeks.

For superficial basal cell carcinoma, it is typically applied five times a week for 6 weeks.

For genital or perianal warts, it is often applied three times a week for up to 16 weeks.

Proper Use

It is important to wash the hands and the treatment area with mild soap and water before application. After applying a thin layer and rubbing it in until it vanishes, the area should be left uncovered; bandages or waterproof dressings should not be used. The cream should remain on the skin for the amount of time directed by a healthcare provider (usually 6 to 10 hours) before being washed off.

Imiquimod cream is for external use only and should not be used in the eyes, nose, mouth, or inside the vagina or anus. Because the medication can weaken condoms and diaphragms, alternative forms of protection or abstinence may be necessary during treatment for genital warts.

Storage and Handling

The cream is often supplied in single-use packets. Once a packet is opened, any remaining cream should be discarded and not saved for future use. If using a pump, follow specific priming instructions provided with the product. The medication should be stored at room temperature and kept away from heat or freezing temperatures.
