IPLEDGE program
Although the goal of the program is to prevent pregnancies of women who take the drug, male patients must also participate in anti-pregnancy restrictions, primarily due to fears that male isotretinoin users might share their prescriptions with females without their physicians' knowledge. There has been no link to birth defects from Accutane associated with males using the drug, though male sexual dysfunction has been suggested by one study. As this has not been conclusively proven, this is not acknowledged as a side effect in the official literature accompanying the medication.
Chronic myelomonocytic leukemia
Azacitidine is a drug approved by the US Food & Drug Administration (FDA) for the treatment of CMML and by the European Medicines Agency for high risk non-proliferative CMML with 10-19% marrow blasts. It is a cytidine analogue that causes hypomethylation of DNA by inhibition of DNA methyltransferase. Decitabine is a similar drug to azacitidine and is approved by the FDA for treatments of all subtypes of MDS, including CMML. Hydroxyurea is a chemotherapy that is used in the myeloproliferative form of CMML to reduce cell numbers.
