Blackbox WarningTOP

Oral route (Capsule)

Thalidomide can cause severe birth defects or embryofetal death, even with 1 dose, if taken during pregnancy. Thalidomide distribution is restricted through the THALOMID REMS (TM) program (formerly known as the S.T.E.P.S. (R) program). The use of thalidomide in multiple myeloma patients results in an increased risk of VTE , such as DVT and pulmonary embolism. Coadministration of dexamethasone increases this risk. Monitor for thromboembolism and consider thromboprophylaxis for individualized cases .

OverviewTOP

Thalidomide is used to treat and prevent erythema nodosum leprosum, a painful skin disease associated with leprosy. It is also used together with dexamethasone (eg, Decadron®) to treat patients with multiple myeloma (a cancer of the blood). Thalidomide works on the immune system to reduce inflammation. It also interferes with the growth of multiple myeloma cells, which are eventually destroyed in the body. Thalidomide is an antineoplastic (cancer medicine) and leprostatic agent.

This medicine is available only under a restricted distribution program called the Thalomid® REMS (Risk Evaluation and Mitigation Strategy) program.

Before UsingTOP

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

AllergiesTOP

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

PediatricTOP

Appropriate studies have not been performed on the relationship of age to the effects of thalidomide in children younger than 12 years of age. Safety and efficacy have not been established.

GeriatricTOP

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of thalidomide in the elderly. However, elderly patients are more likely to have unwanted effects (eg, blood clotting problems, heart rhythm problem), which may require caution and an adjustment in the dose for patients receiving this medicine.

Breast FeedingTOP

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Drug InteractionsTOP

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Other InteractionsTOP

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

PrecautionsTOP

It is very important that your doctor check your progress closely at regular visits to see if the medicine is working properly and to allow for a change in the dose. Blood tests may be needed to check for unwanted effects.

Women should take the necessary precautions to avoid pregnancy while taking thalidomide. Begin 2 forms of effective birth control together 4 weeks before starting treatment, during treatment, even if the dose is stopped for a short time, and for at least 4 weeks after your last dose. Talk to your doctor about the most effective forms of birth control for you and your partner. Call your doctor right away if you think you are pregnant.

Women who can get pregnant must have a negative pregnancy test before starting treatment with this medicine. Pregnancy tests may be done weekly for the first month during treatment, and then every 2 to 4 weeks.

Men who are sexually active must protect their female partner from getting pregnant. Thalidomide will appear in the semen of male patients. If you are sexually active, you must use a latex or synthetic condom every time you have sex with a woman who could get pregnant. If you have had a vasectomy, you still have to use a latex condom during sex. You must use a condom during treatment, even if the dose is stopped for a short time, and for at least 4 weeks after your last dose. Call your doctor right away if you think your sexual partner may be pregnant.

Do not donate blood or sperm while you are taking this medicine and for at least 4 weeks after your last dose.

You must not share this medicine with anyone, even someone who has similar symptoms.

This medicine may increase your risk of having blood clots, a heart attack, or stroke. Check with your doctor right away if you have shortness of breath, chest pain, or leg pain or swelling. These could be symptoms of blood clots. Symptoms of stroke include confusion, difficulty with speaking, double vision, inability to move the arms, legs, or facial muscles, or slow speech.

Do not receive pembrolizumab together with thalidomide and dexamethasone if you have multiple myeloma.

This medicine may make you dizzy, drowsy, or lightheaded. Do not drive or do anything else that could be dangerous until you know how this medicine affects you. If you feel lightheaded, getting up slowing after sitting or lying down may help.

Thalidomide can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

If you can, avoid people with infections. Check with your doctor right away if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
Check with your doctor right away if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
Avoid contact sports or other situations where bruising or injury could occur.

This medicine may cause nerve damage. Check with your doctor right away if you have tingling, burning, numbness, or pain in your hands or feet. These could be symptoms of a nerve condition called peripheral neuropathy.

Serious skin reactions can occur with this medicine. Check with your doctor right away if you have blistering, peeling, or loosening of the skin, red skin lesions, severe acne or a skin rash, sores or ulcers on the skin, or fever or chills while you are using this medicine.

Thalidomide may cause a serious type of reaction called tumor lysis syndrome in patients with multiple myeloma. Call your doctor right away if you have less urine than normal, joint pain, stiffness, or swelling, lower back, side, or stomach pain, a rapid weight gain, swelling of the feet or lower legs, or unusual tiredness or weakness.

This medicine will add to the effects of alcohol and other CNS depressants (medicines that may make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicines for hay fever, allergies, or colds, sedatives, tranquilizers, or sleeping medicine, prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Check with your doctor before taking any of these medicines while you are using thalidomide.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
