Valchlor topical Uses

This medication is used on the skin to treat a certain type of cancer (cutaneous T-cell lymphoma) in people who have received previous skin treatment. Mechlorethamine belongs to a class of drugs known as alkylating agents. It works by slowing or stopping the growth of cancer cells that cause the skin condition.

How to use Valchlor topical

Read the Medication Guide provided by your pharmacist before you start using this medication and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Use this medication as directed by your doctor, usually once a day. After taking this medication out of the refrigerator, apply it within 30 minutes, and be sure to return it to the refrigerator right after each use. Apply a small amount of medication to completely dry skin at least 4 hours before or 30 minutes after showering or washing. Let the treated area(s) dry for 5 to 10 minutes before covering with clothing. You may apply moisturizers to the treated area(s) 2 hours before or 2 hours after applying mechlorethamine.

If someone helps you apply this medication, they must wear disposable gloves. If you are applying it to yourself, you can wear disposable gloves but you do not have to. Whoever applies this medication must wash their hands immediately afterward, even if they have worn gloves (see also Side Effects section). Safely throw away any used gloves in the trash.

Do not cover the treated area with tight dressings or plastic bandages. Ask your doctor whether you may cover the treated area loosely with gauze.

Avoid getting this medication in or around the eyes or eyelids. It can cause pain, burns, blurred vision, and even blindness. Also, do not apply this medication inside the nose or mouth. If you accidentally get this medication in the eyes, rinse for at least 15 minutes with plenty of water, normal saline, or an eye wash solution and get medical help right away (including consultation with an eye doctor). If you get this medication in the nose or mouth, rinse for at least 15 minutes with plenty of water and tell the doctor right away.

Use this medication exactly as prescribed. Do not increase your dose or use this drug more often than directed. Your condition will not improve any faster, and your risk of side effects will increase.
