PublishedLast updated June 20, 2026Download evidence report

Why this drug?

After catastrophic teratogenicity halted its use as a sedative, thalidomide was repurposed for leprosy complications and later multiple myeloma based on anti-angiogenic and immunomodulatory mechanisms.

Known risks

  • Severe birth defects (absolute contraindication in pregnancy)
  • Peripheral neuropathy
  • Thromboembolism
  • Sedation and constipation
