This medication falls into category X.

You must use two acceptable forms of birth control for 1 month before you begin to take bexarotene, at all times during your treatment, and for 1 month after your treatment. Your doctor will tell you which forms of birth control are acceptable. Bexarotene may 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 along with this type of contraceptive.
- You will begin to take bexarotene on the second or third day of your menstrual period. You must have a negative pregnancy test within 1 week of the start of your treatment and every month during your treatment. After each negative pregnancy test, you will be given only 1 month's supply of bexarotene.
- Stop taking bexarotene and call your doctor right away if you think you are pregnant, you miss a menstrual period, or you have sex without using two forms of birth control.
- For male patients:
- You must use a condom every time you have sexual contact with a female who is pregnant or able to become pregnant while you are taking bexarotene and for 1 month after your treatment. Call your doctor if your partner becomes pregnant during this time.

The frequency of application should then be increased as tolerated at weekly intervals to once daily, then twice daily, then three times daily, and finally four times daily. Your health care provider may instruct you to apply bexarotene gel at a different frequency.
- What shoud I avoid?
- You should avoid applying bexarotene gel to areas of healthy skin around a CTCL lesion. Exposure of healthy skin to bexarotene gel may cause unnecessary irritation or redness.
