Bontril and Pregnancy
There are some situations in which it may not be safe to take Bontril, and pregnancy is one of them. The FDA has assigned this medication a pregnancy Category X rating, which means it should never be taken during pregnancy. Bontril may increase the risk of birth defects and miscarriages.
Bontril and Pregnancy: An OverviewBontril® (phendimetrazine tartrate) is a prescription weight loss aid. It is not known if the medication is safe for use during pregnancy.
Bontril and Pregnancy CategoriesThe 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. There are specific requirements for each category, but generally, the categories are defined as follows:
- Category A -- safe
- Category B -- probably safe
- Category C -- may or may not be safe
- Category D -- probably not safe
- Category X -- definitely not safe.
Initially Bontril was not assigned a pregnancy Category rating, probably because it is an older medication. However, in 2012 it was officially given a Category X rating, meaning that it should most certainly not be used during pregnancy. Bontril is closely related to amphetamines, a group of medications that can cause birth defects and miscarriages.
Perhaps more importantly, a pregnant woman is unlikely to benefit from the use of Bontril. This is because pregnant women are generally advised to not lose weight while pregnant, even if they are already overweight when becoming pregnant. Because Bontril would not be absolutely necessary for a pregnant woman, it is recommended that the medication be avoided during pregnancy.
