The U.S. Food and Drug Administration classifies Kapvay (clonidine ER) as a pregnancy Category C medication, which means that it may not be safe for pregnant women to take this medicine. Some animal studies indicated that the drug increased the risk for miscarriages. However, a healthcare provider may prescribe this drug to a pregnant woman if the benefits outweigh the risks.
I'm Pregnant -- Can I Take Kapvay?Kapvay™ (clonidine ER) is a prescription medication approved to treat attention deficit hyperactivity disorder (ADHD) in children and adolescents age 6 to 17 years old. Based on the results of animal studies, this drug may not be safe for use in pregnant women, although the full risks are currently unknown.
What Is Pregnancy Category C?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 C is given to medicines that have not been studied in pregnant humans, but do appear to cause harm to the fetus in animal studies.
Medicines that have not been studied in any pregnant women or animals are automatically given a pregnancy Category C rating.
There is no evidence that clonidine (the active ingredient in Kapvay) causes problems during pregnancy in humans. However, giving clonidine to rats and mice before and during pregnancy increased the risk for miscarriages.
However, it is important to note that animals do not always respond to medicines in the same way that humans do. Therefore, a pregnancy Category C medicine may be given to a pregnant woman if the healthcare provider believes that the benefits to the woman outweigh any possible risks to the unborn child.
