Menopause Home > Minivelle and Pregnancy

As a Category X medication, Minivelle should not be used during pregnancy. Although the full risks are not fully known, Minivelle could cause serious problems. Also, there is no accepted medical reason for a pregnant woman to use this product. If you are using Minivelle and pregnancy occurs, let your healthcare provider know right away.

Can Pregnant Women Use Minivelle?

Pregnant women should never use Minivelle™ (estradiol patch). It is important to understand that estrogens are not effective at preventing miscarriages or other problems in pregnancy; there is no accepted medical reason for pregnant women to use Minivelle.

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. Minivelle is classified as a pregnancy Category X medication.
Pregnancy Category X is given to medications that should not be used during pregnancy, usually due to serious problems that could occur, such as birth defects or miscarriages.
Although Minivelle is a Category X medication, it does not appear to increase the risk of birth defects or other problems. However, there is no accepted, legitimate medical reason for pregnant women to use Minivelle. Therefore, any risk -- no matter how minor or how theoretical -- outweighs the possible benefits. Because the risks are not fully understood, this product should not be used during pregnancy.

Final Thoughts

Minivelle is not approved for any use in pregnant women. If you unintentionally used Minivelle for a while before you realized you were pregnant, it will probably not cause any problems, although you should discuss this with your healthcare provider. If you think you may be pregnant, you should contact your healthcare provider for further instructions.
