- If you’re a male taking bexarotene (Targretin) and have a partner who can become pregnant, use a condom during sex and continue to do so for at least 1 month after your last dose.
- Bexarotene (Targretin) can interact with other medications, herbals, and supplements. Share a list of everything you take with your care team before starting treatment.
- If you take vitamin A supplements, tell your oncology care team before starting bexarotene (Targretin). Taking too much vitamin A can raise the risk for side effects from this medication.
- Bexarotene (Targretin) can make some blood-sugar lowering medications (like insulin or sulfonylureas) work stronger. If you have diabetes, tell your care team if you notice symptoms of low blood sugar like shakiness, sweating, or dizziness.
- Get your lab tests done as scheduled during treatment with bexarotene (Targretin). The medication can cause side effects that don’t have symptoms right away, like changes in cholesterol, thyroid levels, liver function, or white blood cells.

Risks and warnings for Bexarotene (Targretin)
Bexarotene (Targretin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Harm to unborn baby
Bexarotene (Targretin) can cause harm to an unborn baby, so it’s not safe during pregnancy. If you’re able to get pregnant, you’ll need to take a pregnancy test within 1 week before starting the medication and then once a month during treatment. It’s recommended to use two forms of birth control starting 1 month before, during treatment, and for 1 more month after stopping bexarotene (Targretin). One of these should be non-hormonal because hormonal birth control might not work as well with this medication. Let your care team know right away if you become pregnant while taking this medication.
If you're a male taking bexarotene (Targretin) and your partner can become pregnant, you must use a condom during sex and continue to do so for at least 1 month after your last dose.
High cholesterol and triglycerides (fat) in the blood
Bexarotene (Targretin) can cause high levels of cholesterol and triglycerides (fat) in most people who take it. These changes can raise your risk for serious health problems, so it’s important for your care team to monitor your levels closely. Before you start treatment with bexarotene (Targretin), you will do a fasting blood test to check your cholesterol and triglyceride levels. These will be checked weekly at first, then every 2 months once your levels are stable. If your levels get too high during treatment, your oncologist might lower your dose, pause treatment, or give you medication to help manage cholesterol. One commonly used option is atorvastatin.
Inflammation of the pancreas (pancreatitis)
- Risk factors: History of pancreatitis | Uncontrolled high fat levels | Uncontrolled diabetes | Gallbladder problems | Drinking a lot of alcohol | Taking medications that raise fat levels | Taking medications that harm the pancreas
Bexarotene (Targretin) can cause pancreatitis (inflammation of the pancreas), which can be life-threatening. Your risk is higher if you’ve had pancreatitis before, drink a lot of alcohol, or take medications that raise fat levels or affect the pancreas. Tell your care team right away if you have nausea, vomiting, stomach pain, or back pain.
Liver problems
- Risk factors: High doses of bexarotene (Targretin)
Bexarotene (Targretin) can cause liver problems, especially if you’re taking a higher dose. You’ll have regular blood tests to check your liver before starting treatment, and again at 1, 2, and 4 weeks. If your liver tests stay stable, your care team will continue to check them at least every 2 months during treatment. Talk to your oncologist immediately if you notice yellowing of your eyes or skin, reduced appetite, unusual bleeding, or bruising.
Low thyroid hormone levels
Bexarotene (Targretin) can cause hypothyroidism (low thyroid hormone levels). Your care team will check your thyroid function before and during treatment. If your levels drop, your oncologist might have you start thyroid hormone replacement therapy. In studies, about one-third of people taking bexarotene (Targretin) needed these replacement medications. Tell your care team if you feel more tired than usual, cold, or gain weight since these could be signs of low thyroid hormone levels.
Low white blood cell count
Bexarotene (Targretin) can lower your white blood cell count, which might make it harder for your body to fight infections. In studies, this usually happened within 4 to 8 weeks of starting treatment, and got better within about 30 days after lowering the dose or stopping the medication. Your care team will check your blood counts before starting treatment and regularly during treatment to monitor for these changes. Let them know if you have symptoms like frequent infections, fever, or feeling more tired than usual.
Cataracts
In studies, some people had new or worsening cataracts after taking bexarotene (Targretin). If you notice vision changes or problems seeing, tell your oncologist. They might refer you for an eye exam to check for cataracts or other eye problems.
Low blood sugar in people with diabetes
If you're taking insulin or other diabetes medications like sulfonylureas or thiazolidinediones, bexarotene (Targretin) can make them work more strongly and raise your risk of low blood sugar (hypoglycemia). This hasn’t been seen when bexarotene (Targretin) is used by itself, but it’s important to watch for symptoms like shakiness, sweating, or dizziness. Talk to your care team before starting this medication if you're taking anything to manage your blood sugar.
Sensitivity to the sun
bexarotene (Targretin), like other retinoids, can make your skin more sensitive to sunlight. Some people have had sunburns or skin irritation after being in the sun while taking this medication. To help prevent this, limit direct sunlight and tanning beds during treatment. If you go outside, wear sunscreen, protective clothing, and a hat.
