What it is used for

TARGRETIN is a prescription medicine used to treat the skin problems that happen with a type of cancer called cutaneous T-cell lymphoma (CTCL) after treatment with at least one other type of medicine by mouth or injection, did not work or has stopped working.

It is not known if TARGRETIN is safe and effective in children.

The most important thing to know

TARGRETIN can cause serious side effects, including major birth defects to an unborn baby, if taken during pregnancy.

For females who can become pregnant:

• You should avoid becoming pregnant during treatment with TARGRETIN.
• Do not take TARGRETIN if you are pregnant or plan to become pregnant.
• Your healthcare provider will do a pregnancy test, within 1 week before you start TARGRETIN, and each month during treatment with TARGRETIN to make sure that you are not pregnant.
• You must use two effective forms of birth control together starting 1 month before you begin treatment with TARGRETIN, during treatment, and for 1 month after stopping TARGRETIN. Birth control pills (oral contraceptives) and other hormonal forms of birth control may not be effective if used with TARGRETIN. At least one of the forms of birth control that you choose should not contain hormones. Talk to your healthcare provider about what forms of birth control may be right for you during treatment with TARGRETIN.
• You should start taking TARGRETIN on the second or third day of a normal menstrual period. Follow your healthcare provider’s instructions about when to start TARGRETIN.
• Call your healthcare provider right away, if you become pregnant or think that you are pregnant during treatment with TARGRETIN, and for 1 month after you stop taking TARGRETIN.

For males:

• You must use a condom with female partners who are pregnant, might be pregnant, or who are able to become pregnant, during treatment with TARGRETIN and for at least 1 month after your last dose.

How to take it

• Take TARGRETIN exactly as your healthcare provider tells you.
• Your healthcare provider will tell you how many TARGRETIN capsules to take each day. Your healthcare provider may change your daily dose of TARGRETIN as needed to treat your CTCL or if you get certain side effects. You should not change your dose unless your healthcare provider tells you to.

Take your dose of TARGRETIN one time a day with a meal. Your healthcare provider will do blood tests before you start TARGRETIN and during treatment to check for side effects.

Side effects, and when to stop

TARGRETIN can cause serious side effects, including:

• Increased levels of fats (lipids) called cholesterol or triglycerides, in your blood are common with TARGRETIN, but can also be serious. Your healthcare provider may prescribe you medicines to treat high cholesterol or triglycerides levels, reduce your dose, temporarily stop treatment or completely stop treatment with TARGRETIN if you have this problem.
• Inflammation of the pancreas (acute pancreatitis). TARGRETIN can sometimes cause pancreatitis that comes on suddenly (acute), and that can lead to death. Your risk of developing acute pancreatitis may be greater if you:
  • o have had pancreatitis in the past
  • o high levels of fats in your blood that are not controlled
  • o drink large amounts of alcohol
  • o have gallbladder problems
  • o have diabetes that is not controlled
  • o take certain medicines that can increase the amount of triglycerides in your blood
  • o take medicines that can harm your pancreas

Tell your healthcare provider right away if you develop signs or symptoms of pancreatitis during treatment with TARGRETIN, including:

• • o nausea that will not go away
  • o vomiting
  • o stomach-area (abdominal) or back pain
• Liver problems, including liver failure. TARGRETIN can cause increased liver function blood test results, or liver problems that can lead to death.
• Thyroid problems (hypothyroidism) are common with TARGRETIN. Your healthcare provider may prescribe thyroid hormone treatment for you if needed.
• Low white blood cell count is common with TARGRETIN, but may sometimes be severe.
• New or worse cataracts. Tell your healthcare provider about any changes in your vision during treatment with TARGRETIN. You may need to have an eye examination.
• Risk of low blood sugar in people who have diabetes. TARGRETIN can interact with certain medicines used to treat diabetes, such as insulin, sulfonylurea medicines, and thiazolinedione medicines. If you have diabetes, talk to your healthcare provider about your diabetes medicines and your risk for low blood sugar if you take TARGRETIN.

The most common side effects of TARGRETIN include:

• headache
• asthenia
• rash
• nausea
• infection
• stomach-area (abdomen) pain
• swelling of your hands, arms, feet or legs
• dry skin

These are not all the possible side effects of TARGRETIN. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
