Suprenza and Pregnancy
As a pregnancy Category X medicine, Suprenza (orally disintegrating phentermine) should not be taken if you are pregnant -- the risks clearly outweigh the benefits. This is mainly due to the fact that this product is used to help people lose weight, which is not recommended for women who are pregnant.
Can Pregnant Women Use Suprenza?Suprenza™ (orally disintegrating phentermine) is a prescription weight loss medication approved for short-term use only. This medication is considered a pregnancy Category X medication, meaning it should not be used by pregnant women.
What Is Pregnancy Category X?The U.S. Food and Drug Administration (FDA) uses a pregnancy category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. 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 potential benefits.
Suprenza has not been adequately studied in pregnant women or pregnant animals. Therefore, the effects of the medicine on a developing baby are not completely known. A similar medication was shown to increase the risk for lung problems and miscarriage when given to pregnant rats.
There have been reports of miscarriage or stillbirth occurring in women who took phentermine (the active ingredient in Suprenza) in early and late pregnancy. There have also been reports of heart valve problems in infants born to women who took phentermine early in pregnancy. However, it is difficult to say for certain whether the medication or something else caused these problems.
Perhaps more importantly, a pregnant woman is unlikely to benefit from the use of Suprenza. This is because pregnant women are generally advised to not lose weight while pregnant, even if they are already overweight when becoming pregnant. Because Suprenza would not be absolutely necessary for a pregnant woman, it is recommended that this product be avoided during pregnancy.
