Drug class: Immunomodulatory agent; Anti-inflammatory; Antineoplastic

Overview

Thalidomide is a prescription medication used to treat multiple myeloma (a type of blood cancer) and certain complications of leprosy, such as erythema nodosum leprosum (ENL). It works by affecting the immune system and reducing inflammation, as well as slowing the growth of some cancer cells. Thalidomide is known for its serious risk of causing severe birth defects if taken during pregnancy. Because of this, it is only available under strict safety programs and is never used in pregnant women or women who could become pregnant unless all precautions are followed. Patients should be aware that thalidomide can cause drowsiness, nerve damage, and increase the risk of blood clots. Regular monitoring and adherence to safety instructions are essential while taking this medication.
