About This Drug
Thalidomide is a drug used to treat cancer. It is given by mouth.
Possible Side Effects
- Generalized weakness and discomfort (aches or pains)
- Feeling tired
- Effects on the nerves are called peripheral neuropathy. You may feel numbness, tingling, or pain in your hands and feet. It may be hard for you to button your clothes, open jars, or walk as usual. The effect on the nerves may get worse with more doses of the drug. These effects get better in some people after the drug is stopped but it does not get better in all people.

- Sensitivity to light (photosensitivity). Photosensitivity means that you may become more sensitive to the light from the sun, sun lamps, and tanning beds. Your eyes may water more, mostly in bright light.
- Blood clots. A blood clot in your leg may cause your leg to swell, appear red and warm, and/or cause pain. A blood clot in your lungs may cause trouble breathing, pain when breathing, and/or chest pain.
- Bone marrow depression. This is a decrease in the number of white blood cells, red blood cells, and platelets. This may raise your risk of infection, make you tired and weak (fatigue), and raise your risk of bleeding.
- Very harmful effects on an unborn child, including death. Even 1 dose taken by a pregnant woman can cause these very harmful effects. Your healthcare team will talk to you and give you written information about this risk.
