Pomalyst (pomalidomide) is an oral anticancer medication. It treats multiple myeloma in people who’ve received at least 2 prior therapies, including lenalidomide (Revlimid) and a proteasome inhibitor, like bortezomib (Velcade). It can also treat Kaposi sarcoma in adults. Pomalyst (pomalidomide) is convenient to take because you only take it once daily for 3 weeks out of every 4-week anticancer treatment cycle. But because of the risk of serious side effects (e.g., blood clots and birth defects), Pomalyst (pomalidomide) is only available under a restricted distribution program called a Risk Evaluation and Mitigation Strategy (REMS) program.
Multiple myeloma, previously treated with at least 2 prior therapies
Kaposi sarcoma
Pomalyst (pomalidomide) works by stimulating the immune system to fight cancer cells. In addition, it targets specific proteins within cancer cells and stops the cancer cells from growing. Pomalyst (pomalidomide) also works by blocking the blood supply to myeloma cells, which helps minimize the growth of new myeloma cells.

Taken once a day
Taken by mouth, so good for people who don’t like needles
Works well to treat people who didn’t respond well to other treatments for myeloma
Commonly causes tiredness, diarrhea, and rash
Can cause blood clots so might also need to take a blood thinner
Can only be filled at certified pharmacies enrolled in the Pomalyst (pomalidomide) REMs program
You should take Pomalyst (pomalidomide) by mouth once a day with or without food. Swallow the capsule whole with water. Don’t chew, crush, or break open the capsule.
If you’ve kidney problems and are currently getting hemodialysis, you should take Pomalyst (pomalidomide) after your hemodialysis session on dialysis days.
If you miss a dose of Pomalyst (pomalidomide) or vomit after taking a dose, you can take the missed dose if it’s more than 12 hours before your next dose. However, if it’s less than 12 hours before your next dose, you can skip the missed dose. Just resume your next dose at the normally scheduled time.
Because Pomalyst (pomalidomide) raises your risk for blood clots, your healthcare provider will most likely prescribe medications to help prevent blood clots. Depending on your risk for blood clots this can include medications like aspirin, warfarin (Coumadin), or enoxaparin (Lovenox).
Certain medications, like fluvoxamine (Luvox) and ciprofloxacin (Cipro) can raise the level of Pomalyst (pomalidomide) in your body and put you at higher risk for serious side effects, such as blood clots. It’s important to tell your provider and pharmacist about all the medications you take, including supplements and over-the-counter (OTC) medications. Your provider can guide you to safer alternatives or on how to best take your medications.
Due to the risk of harm to an unborn baby, you shouldn’t donate blood while on treatment with Pomalyst (pomalidomide) and for at least a month after your last dose.
Ask your provider or pharmacist about the best way to handle and throw away Pomalyst (pomalidomide) safely. Anticancer medications can be very harmful to people who handle or come into contact with them.
Pomalyst (pomalidomide) 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.
Pomalyst (pomalidomide) can’t be used in pregnancy because it can cause severe birth defects and death to the unborn baby. If you’re a female who’s able to become pregnant, you either need to avoid heterosexual intercourse or use 2 methods of effective birth control for at least a month before starting Pomalyst (pomalidomide) treatment, during treatment, and for at least a month after your last dose. You also need to have 2 negative pregnancy tests—one test 2 weeks before, then another test within 24 hours of starting Pomalyst (pomalidomide). You’ll also need to take pregnancy tests biweekly or monthly while on treatment. If you become pregnant while taking Pomalyst (pomalidomide), stop taking it right away and let your healthcare provider know.
Pomalyst (pomalidomide) is also present in the semen of males who take Pomalyst (pomalidomide). Because of this, males taking Pomalyst (pomalidomide) with female partners who can become pregnant should use a latex or synthetic condom during sexual intercourse while on treatment and for a month after the last dose. This is recommended even if the male has had a vasectomy. Males taking Pomalyst (pomalidomide) must not donate sperm.
Due to the risk of harm to an unborn baby, Pomalyst (pomalidomide) is only available through a restricted program called Pomalyst (pomalidomide) REMS. This program requires people treated with Pomalyst (pomalidomide) to sign a Patient-Physician Agreement Form and complete specific requirements to receive Pomalyst (pomalidomide). For females who are able to become pregnant, this includes complying with pregnancy testing, contraception requirements, and monthly telephone surveys. For males, this includes complying with contraception requirements. Pomalyst (pomalidomide) is available only from certain pharmacies that are certified in the Pomalyst (pomalidomide) REMS program.
Risk factors: History of blood clots | High cholesterol | Smoking | High blood pressure
Pomalyst (pomalidomide) can raise your risk of blood clots. These clots can occur anywhere in your body, including your lungs (pulmonary embolism, or PE), legs (deep vein thrombosis, or DVT), brain (stroke), and heart (heart attack). Get emergency help right away if you have any signs of a blood clot:
Brain: weakness or numbness in your arms, legs, or face on one side of the body, trouble speaking, blurred vision, dizziness, loss of balance, trouble walking, or confusion
Heart: chest pain, sweating, nausea, or dizziness
Lungs: trouble breathing, chest pain, or cough
Legs: cramps, swelling, pain, or muscle tightness
Due to the higher risk of blood clots while taking Pomalyst (pomalidomide), your healthcare provider might also recommend that you also take a blood thinner to help prevent blood clots.
Pomalyst (pomalidomide) can cause your white blood cells, red blood cells, and platelets to drop. When these cell counts are lower than normal, you have a higher risk of anemia, bleeding, bruising, and infections. Your provider will check your blood counts often while you’re receiving Pomalyst (pomalidomide). Let your provider know if you develop a fever or start to feel sick or have any unusual bruising or bleeding. If this happens you might need to have your dose lowered or stop this medication altogether. If your blood counts drop too low, you may need a blood transfusion.
Pomalyst (pomalidomide) can cause liver damage. Rarely, this can lead to life-threatening liver failure. Your provider will monitor your liver health through lab work at the start of treatment as well as monthly while you’re taking Pomalyst (pomalidomide). If you experience higher levels of liver enzymes, your provider might need to stop Pomalyst (pomalidomide) (either temporarily or permanent) or switch you to a different medication. Let your provider know if you experience tiredness, loss of appetite, nausea or vomiting, dark urine, right-side stomach pain, or yellowing of the eyes or skin, as these can be signs of liver problems.
Pomalyst (pomalidomide) can cause severe skin reactions like Stevens-Johnson syndrome (SJS), which can become life-threatening. Tell your provider immediately if you develop painful blisters, skin wounds, or peeling skin, as these are signs of a serious skin reaction that requires immediate medical attention.
Pomalyst (pomalidomide) can cause symptoms of nerve damage including tingling, numbness, pain, and a burning sensation in your hands, feet, or legs. Call your healthcare provider if you develop symptoms of nerve damage. Your provider will see how severe your symptoms are and talk with you about next steps.
Pomalyst (pomalidomide) can cause dizziness and confusion. Your risk is higher if you’re also taking other medications that can cause dizziness or confusion, and if you’re drinking alcohol. You should avoid situations where you need to be alert, such as driving, until you get used to how the medication affects you.
Although rare, taking Pomalyst (pomalidomide) may raise your risk of developing a new cancer, such as a blood cancer called acute myeloid leukemia (AML). This happened in people who took Pomalyst (pomalidomide) as an investigational therapy for reasons outside of multiple myeloma. Speak with your healthcare provider about your risk of developing new cancers while taking Pomalyst (pomalidomide).
Risk factors: High tumor burden
Treatment with Pomalyst (pomalidomide) can cause a serious reaction called tumor lysis syndrome (TLS). TLS is a condition where many cancer cells die quickly and suddenly break down in your body. In the process, these cells release their inner contents, like uric acid, potassium, and phosphorus, into your blood. High levels of uric acid and electrolytes in your body can cause serious problems, such as kidney damage and abnormal heart rhythms.
Your provider will order labs for you regularly to check for signs of TLS. Tell your provider right away if you’re urinating less than usual or have dark urine, muscle cramps, or a racing heartbeat.
Multiple myeloma: The typical dose is 4 mg by mouth once daily on days 1 through 21 of every 28-day cycle, in combination with dexamethasone.
Kaposi sarcoma: The typical dose is 5 mg by mouth once daily on days 1 through 21 of every 28-day cycle, in combination with dexamethasone.
Your dose might be different if you experience certain side effects, have kidney or liver problems, or you’re taking medications that might interact with Pomalyst (pomalidomide).
