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.

Thromboprophylaxis is recommended, and the regimen choice should be based on assessment of the underlying risk factors of the patient.
