Oral route (Capsule)

Pomalidomide is contraindicated in pregnancy. Pomalidomide is a thalidomide analogue, and thalidomide is a known human teratogen that causes severe birth defects or embryo-fetal death. In females who can become pregnant, obtain 2 negative pregnancy test before treatment initiation. It is required that females of reproductive potential use 2 forms of contraception or abstain from heterosexual sex during and for 4 weeks after stopping treatment with pomalidomide. The only way to acquire pomalidomide is through a restricted distribution program called POMALYST REMS. DVT, pulmonary embolism, myocardial infarction, and stroke have been reported in patients with multiple myeloma treated with pomalidomide. Thromboprophylaxis is recommended, and the regimen choice should be based on assessment of the underlying risk factors of the patient.
