Epiduo Gel (Adapalene + Benzoyl Peroxide)

How to use Epiduo|Precautions & warnings|Side effects|Interactions|Dosage

Epiduo

Epiduo is the brand name of a topical gel containing two ingredients, adapalene and benzoyl peroxide. Adapalene is a retinoid (vitamin A derivative) and benzoyl peroxide works as an antibiotic and skin-peeling agent.

Adapalene works by affecting the growth of cells and decreasing swelling and inflammation. Benzoyl peroxide works by reducing the amount of acne-causing bacteria and by causing the skin to dry and peel off.

Together, these ingredients help to kill the bacteria that cause pimples and reduce inflammation. This product may reduce the number and severity of acne pimples and promote quick healing of pimples that do appear.

This product is not available over-the-counter (OTC), therefore it can only be purchased if you have a prescription from a doctor or dermatologist.

How to use Epiduo

How should I apply it?

Wash your hands before applying this medication. Gently clean the affected skin with a mild or soap-free cleanser and pat dry. Apply a thin layer of this medication usually once daily or as directed by your doctor. Use your fingertips to apply a small amount of medication (about the size of a pea) to the affected areas of skin.

Use this medication on the skin only. Do not apply to the inner lip area, inside the nose/mouth, or on mucous membranes. Do not apply to cut, scraped, sunburned or eczema-affected skin.

Avoid getting this medication in your eyes. If this medication gets into your eyes, flush with large amounts of water. Call your doctor if eye irritation develops. Wash your hands after using the medication to avoid accidentally getting it in your eyes.

Your dosage and treatment plan is based on your medical condition and response to treatment.

During the first few weeks of using adapalene, your acne might appear worse because the medication is working on pimples forming inside the skin.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time each day. Do not use a larger amount or use it more frequently than recommended. Your skin will not improve any faster, and it will increase the risk of developing redness, peeling, and pain.

Tell your doctor if your condition does not improve or if it worsens.

How do I store it?

Epiduo is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store Epiduo in the bathroom or the freezer. There may be different brands of adapalene + benzoyl peroxide that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

You should not flush this product down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.

Precautions & warnings

What should I know before using Epiduo?
