Belviq and Pregnancy
Because women should not be trying to lose weight during pregnancy, Belviq (lorcaserin) should not be given to a pregnant woman. The U.S. Food and Drug Administration (FDA) has given this medication a pregnancy Category X rating, meaning it should be avoided during pregnancy. Although this product has not been adequately studied in pregnant women, it did cause problems during animal studies.
Can Pregnant Women Take Belviq?Belviq® (lorcaserin) is a prescription weight loss medication. Due to the potentially serious risks, pregnant women should not use this drug.
What Is Pregnancy Category X?The U.S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Belviq is classified as a pregnancy Category X medication.
Pregnancy Category X is given to medicines that show problems to the fetus in animal studies or in human use of the medication. With this category, the potential risks clearly outweigh the benefits.
Belviq has not been adequately studied in pregnant women. In animal studies, the drug did not appear to cause birth defects when given to pregnant rats and rabbits. However, in very high doses (about 44 times the recommended human dose), it increased the risk for miscarriage in the pregnant rats. In addition, baby rats born to mother rats given Belviq at any dose had lower-than-normal body weights, a problem which continued into their adulthood.
Perhaps more importantly, women are generally advised to gain weight -- not lose weight -- during pregnancy, even if they are already overweight or obese. Weight loss during pregnancy could be harmful to a developing fetus. A pregnant woman would gain no medical benefit from taking Belviq, and the medication should be avoided during pregnancy.
If you are pregnant and overweight or obese, talk to your healthcare provider about the best way to manage your weight during your pregnancy. He or she will tell you how much weight you should safely gain during pregnancy, and help you develop a weight management plan that includes eating a healthy diet and exercising. You should not take diet pills while you are pregnant.
