Before Using This Medicine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For bexarotene, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to bexarotene or other retinoid (vitamin A) preparations. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy—Bexarotene must not be taken during pregnancy because of the possible risks to the infant. In addition, bexarotene must not be taken if there is a chance that you may become pregnant 1 month before treatment, during treatment, and within 1 month after treatment is ended. Women who are able to have children must have a pregnancy test done within 1 week before starting bexarotene, to make sure they are not pregnant. The pregnancy test must be repeated once a month during treatment. For 1 month before treatment with bexarotene, during treatment, and for 1 month after treatment is over, you must use two effective forms of birth control at the same time. Bexarotene may interfere with the effectiveness of hormonal birth control (such as the pills), so one form of birth control should be non-hormonal, such as condoms. Male patients with sexual partners who are pregnant, possibly pregnant, or who could become pregnant must use condoms during sexual intercourse while taking bexarotene and for at least 1 month after taking the last dose. Be sure you have discussed this information with your doctor.

Breast-feeding—It is not known whether this medicine passes into breast milk. However, bexarotene is not recommended during breast-feeding, because it may cause unwanted effects in nursing babies.

Children—Studies of this medicine have been done only in adult patients, and there is no specific information comparing the use of bexarotene in children with use in other age groups.

Older adults—This medicine has been tested in patients 60 years of age or older and has not been shown to cause different side effects or problems in older people than it does in younger adults. However, elderly patients may be more sensitive to the effects of bexarotene.

Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose or other precautions may be necessary.

Precautions While Using This Medicine

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for unwanted effects.

While you are being treated with bexarotene, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor"s approval . Bexarotene may lower your body"s resistance, and there is a chance you might get the infection that the immunization is meant to prevent. In addition, other persons living in your household should not take oral polio vaccine, since there is a chance they could pass the polio virus on to you. Also, avoid persons who have taken oral polio vaccine within the last several months. Do not get close to them, and do not stay in the room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.

Bexarotene can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

  • If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
  • Check with your doctor immediately if you notice any unusual bleeding or bruising; black, tarry stools; blood in urine or stools; or pinpoint red spots on your skin.
  • Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
  • Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
  • Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
  • Avoid contact sports or other situations where bruising or injury could occur.

Bexarotene may cause your skin to be more sensitive to sunlight than it is normally. Exposure to sunlight, even for brief periods of time, may cause a skin rash, itching, redness or other discoloration of the skin, or a severe sunburn. When you begin taking this medicine:

  • Stay out of direct sunlight, especially between the hours of 10:00 a.m. and 3:00 p.m., if possible.
  • Wear protective clothing, including a hat. Also, wear sunglasses.
  • Apply a sun block product that has a skin protection factor (SPF) of at least 15. Some patients may require a product with a higher SPF number, especially if they have a fair complexion. If you have any questions about this, check with your health care professional.
  • Apply a sun block lipstick that has an SPF of at least 15 to protect your lips.
  • Do not use a sunlamp or tanning bed or booth.
