Uses of Thalidomide

It is commonly used for:

• Erythema nodosum leprosum: Treats this painful inflammatory skin condition associated with leprosy.
• Certain other conditions: Used under strict specialist supervision for specific inflammatory and cancer-related conditions.

How Thalidomide works
Thalidomide works by modifying the activity of the immune system and reducing the growth of new blood vessels that tumours need to grow.
It affects certain immune cells and reduces the production of substances that promote inflammation.
Because thalidomide also affects the formation of blood vessels, it can help slow the growth of cancers such as multiple myeloma, but its use requires very strict medical supervision due to serious risks, including severe birth defects if used during pregnancy.
