Thalidomide, sold under the brand names Contergan and Thalomid among others, is an oral medication used to treat a number of cancers (e.g., multiple myeloma), graft-versus-host disease, and many skin disorders (e.g., complications of leprosy such as skin lesions).[6][7] Thalidomide has been used to treat conditions associated with HIV: aphthous ulcers, HIV-associated wasting syndrome, diarrhea, and Kaposi's sarcoma, but increases in HIV viral load have been reported.[6]

Common side effects include sleepiness, rash, and dizziness.[6] Severe side effects include tumor lysis syndrome, blood clots, and peripheral neuropathy.[8] Thalidomide is a known human teratogen and carries an extremely high risk of severe, life-threatening birth defects if administered during pregnancy. It causes skeletal deformities such as amelia (absence of legs and/or arms), absence of bones, and phocomelia (malformation of the limbs). A single dose of thalidomide, regardless of dosage, is enough to cause teratogenic effects.[6]

Thalidomide was first marketed in 1957 in West Germany, where it was available over the counter.[9][10] When first released, thalidomide was promoted for anxiety, trouble sleeping, "tension", and morning sickness.[10][11] While it was initially thought to be safe in pregnancy, concerns regarding birth defects arose, resulting in its removal from the market in Europe in 1961.[9][10] The total number of infants severely harmed by thalidomide use during pregnancy is estimated at over 10,000, possibly 20,000, of whom about 40% died around the time of birth.[6][10] Those who survived had limb, eye, urinary tract, and heart problems.[9] Its initial entry into the US market was prevented by Frances Kelsey, a reviewer at the FDA.[11] The birth defects caused by thalidomide led to the development of greater drug regulation and monitoring in many countries.[9][11]

It was approved in the United States in 1998 for use as a treatment for cancer.[6] It is on the World Health Organization's List of Essential Medicines.[12] It is available as a generic medication.[8][13]
