Why do some people not use thalidomide?

Some people do not use thalidomide due to its severe side effects, including the risk of birth defects if taken during pregnancy. Additionally, its use is restricted to specific medical conditions, such as multiple myeloma and certain skin conditions related to leprosy, which limits its availability. Concerns over potential side effects and the need for careful monitoring also contribute to its cautious use. Furthermore, regulatory guidelines and the need for patient education play a critical role in its prescription.
