Diabetes Home > Cycloset and Pregnancy

Based on the results of clinical studies on bromocriptine (the active ingredient in Cycloset), the medication is probably safe for pregnant women. However, this drug should only be used if the benefits clearly outweigh the potential risks. If pregnancy occurs while you are taking Cycloset, your healthcare provider will weigh the benefits and risks before making a recommendation for your situation.


Can You Take Cycloset While Pregnant?

Cycloset (bromocriptine mesylate) is a prescription medication approved to treat type 2 diabetes. Although the drug appears to be relatively safe for use during pregnancy, it should only be used if the benefits outweigh the risks.

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.
Although animal studies showed a few problems when bromocriptine (the active ingredient in Cycloset) was used during pregnancy, studies in humans suggest that the drug is probably safe for use during pregnancy.
However, it is important to note that the limited studies of bromocriptine in pregnancy cannot completely rule out the possibility of fetal harm. Therefore, a pregnant woman should take Cycloset only if her healthcare provider believes that the benefits outweigh any possible risks to the unborn child.
(If you are taking bromocriptine for any other reason other than type 2 diabetes, please see Parlodel and Pregnancy, as this article addresses the use of the medication for other reasons, including infertility.)
