Asthma Home > Qvar and Pregnancy

The FDA has classified Qvar as a pregnancy Category C medicine, meaning that while it has not been studied in pregnant humans, it does appear to cause harm to the fetus in animal studies. In animal studies on Qvar and pregnancy, the medication caused birth defects and miscarriages when it was given to pregnant mice and rabbits. Be sure to notify your healthcare provider immediately if you are taking Qvar and pregnancy occurs.

Is Qvar Safe During Pregnancy?

Qvar® (beclomethasone inhaler) may not be safe for women who are pregnant. In animal studies that looked at the effects of Qvar during pregnancy, the drug caused birth defects and miscarriages.
 

Qvar and 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. Also, medicines that have not been studied in any pregnant women or animals are automatically given a pregnancy Category C rating.
 
Qvar was given a pregnancy Category C rating because of potential problems in animal studies. When given to pregnant mice and rabbits, Qvar increased the risk of birth defects and miscarriages.
 
However, it is important to note that animals do not always respond to medicines the same way that humans do. A pregnancy Category C medicine may be given to a pregnant woman if the healthcare provider believes that the benefits to the pregnant woman outweigh any possible risks to the unborn child. Because medications like Qvar can be essential for people with asthma, healthcare providers sometimes recommend that women continue to take Qvar during pregnancy.
