Bexarotene Topical : Uses, Side Effects, Interactions & More

Why is this medication prescribed?

Topical bexarotene is used to treat cutaneous T-cell lymphoma (CTCL, a type of skin cancer) that cannot be treated with other medications. Bexarotene is in a class of medications called retinoids. It works by stopping the growth of cancer cells.

How should this medicine be used?

Topical bexarotene comes as a gel to apply to the skin. It is usually applied once every two days in the beginning and is applied gradually more frequently up to two to four times a day. Use topical bexarotene at around the same time every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Use bexarotene exactly as directed. Do not use more or less or use it more often than prescribed by your doctor.

Your doctor will likely prescribe a low dose of topical bexarotene and increase it gradually, no more than once a week. Your doctor may lower your dose if you experience side effects.

Your condition may improve as soon as 4 weeks after you start using topical bexarotene, or it may take several months before you notice any improvement. Continue using topical bexarotene after noticing improvement; your condition may continue to improve. Do not stop using bexarotene topical without talking to your doctor.

Bexarotene gel can catch fire. Do not use this medicine near a heat source or near an open flame, such as a cigarette.

Bexarotene gel is for external use only. Do not take the medicine and keep it away from the eyes, nostrils, mouth, lips, vagina, tip of penis, rectum, and anus.

You can bathe, shower, or swim during your topical bexarotene treatment, but you should only use a mild, non-deodorant soap. You should wait at least 20 minutes after bathing or showering before applying bexarotene topical. After applying the medicine, do not bathe, swim, or shower for at least 3 hours.

Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.

To use the gel, follow these steps:

  1. Wash your hands.
  2. If you are using a new tube of bexarotene gel, remove the cap and verify that the tube opening is covered with a metal security seal. Do not use the tube if you do not see the security seal or if the seal has been punctured. If you see the security seal, turn the cap over and use the sharp point to pierce the seal.
  3. Use a clean finger to apply a generous layer of gel to the area to be treated only. Be careful not to apply gel to healthy skin around the affected area. Do not rub the gel on the skin. You should be able to see some gel on the affected area once you are done applying it.
  4. Do not cover the treated area with a tight bandage or dressing unless your doctor tells you to.
  5. Wipe the finger that you used to apply the gel with a tissue and throw it away. Wash your hands with soap and water.
  6. Allow the gel to dry for 5-10 minutes before covering it with loose clothing. Do not wear tight clothing over the affected area.

What should I know about storage and disposal of this medication?

Keep this medicine in the container it came in, tightly closed, and out of the reach and sight of children. Store at room temperature and away from light, excess heat, open flames, and moisture (not in the bathroom).

Unnecessary medications must be disposed of in special ways to ensure they cannot be consumed by pets, children, and others. However, you should not flush this medicine down the toilet. Instead, the best way to dispose of your medications is through a drug take-back program. Talk to your pharmacist or contact your local garbage / recycling department to learn about take-back programs in your community. Check out the FDA drug safe disposal website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medicines out of the sight and reach of children, as many containers (such as those containing weekly pills and those for eye drops, creams, patches and inhalers) are not child-resistant and small children can easily open them. To protect young children from poisoning, always close the safety caps and immediately place the medicine in a safe place, one that is upright and out of their sight and reach. http://www.upandaway.org
