Revatio and Pregnancy
The FDA classifies Revatio (sildenafil citrate) as a pregnancy Category B medication, meaning it is generally considered safe for use during pregnancy. When large doses were given in animal studies, it did not cause problems in the offspring. However, animals do not always respond in the same way that humans do, so your healthcare provider should only prescribe Revatio if the benefits outweigh the risks.
Can Pregnant Women Take Revatio?Revatio® (sildenafil citrate) is a prescription medication used to improve the ability to exercise and to slow down worsening conditions in people with pulmonary arterial hypertension (PAH). In general, it is considered safe for pregnant women to take Revatio.
What Is Pregnancy Category B?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 B is given to medicines that have not been adequately studied in pregnant humans, but do not appear to cause harm to the fetus in animal studies.
Also, medications that have been shown to be safe for use in pregnancy in humans (but have caused problems in laboratory animals) are also given a Category B rating.
This medication is generally thought to be safe for use during pregnancy. In animal studies, giving very high doses to pregnant rats and rabbits did not cause any problems in the offspring. However, there are no studies of Revatio use in pregnant women.
It is important to note that animals do not always respond to medicines in the same way that humans do. Therefore, a pregnancy Category B 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.
