Targretin : Uses, Side Effects, Interactions & More


Targretin should not be taken by patients who are pregnant or who may become pregnant. There is a high risk that Targretin will cause the baby to be born with birth defects (problems that are present at birth).

Talk to your doctor about the risks of taking Targretin.

For female patients:

If you are able to become pregnant, you should avoid becoming pregnant during your treatment with Targretin. You must use two acceptable methods of birth control for 1 month before you start taking Targretin, at all times during your treatment, and for 1 month after your treatment. Your doctor will tell you which birth control methods are acceptable. Targretin can decrease the effectiveness of hormonal contraceptives (birth control pills, patches, rings, implants, and injections), so it is especially important to use a second form of birth control in conjunction with this type of contraceptive.

You will start taking Targretin on the second or third day of your menstrual period. You must have a negative pregnancy test within a week of starting your treatment and every month during your treatment. After each negative pregnancy test, you will be given only a 1-month supply of Targretin.

Stop taking Targretin and call your doctor right away if you think you are pregnant, miss a menstrual period, or have sex without using two methods of birth control.

For male patients:

You should use a condom every time you have sexual contact with a woman who is pregnant or may become pregnant while taking Targretin and for 1 month after your treatment. Call your doctor if your partner becomes pregnant during this time.

Why is this medication prescribed?

Targretin (Bexarotene) is used to treat cutaneous T-cell lymphoma (CTCL, a type of skin cancer) in people whose disease could not be successfully treated with at least one other medicine. Targretin is in a class of medications called retinoids. It works by stopping the growth of cancer cells.

How should this medicine be used?

Targretin (Bexarotene) comes as capsules to take by mouth. It is usually taken once a day with food. Take Targretin 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. Take Targretin exactly as directed. Do not take more or less, or take it more often than prescribed by your doctor.

Swallow the capsules whole; do not chew the capsules or dissolve them in liquid or in your mouth. If you cannot swallow the capsules whole, talk to your doctor.

Targretin can be harmful if it comes in contact with your skin. Do not touch the capsules or capsule powder if they are broken or leaking. If the powder from a broken capsule gets on your skin, wash the area with soap and water immediately and call your doctor.

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.
