Is it okay to take orlistat while pregnant?

No. Orlistat has not been tested on women who are pregnant so i would not recommend using it. It is important to eat well and stay active during pregnancy. Talk with your doctor about the right plan for you.
Yes. Orlistat is listed as category b in pregnancy, meaning that it is a safe medication to take, however, i would avoid use of any medication in the first few weeks of pregnancy to be completely safe, especially given the fact that orlistat is not an emergency medication to take.
