Metolazone and Pregnancy: An Overview
) is a pregnancy Category B medicine, meaning that the drug is probably safe for use during pregnancy, although the full risks are not known.
Metolazone and Pregnancy Category B
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. Pregnancy Category B is given to medicines that have not been studied in pregnant humans but that do not appear to cause harm to the fetus in animal studies.
However, it is important to note that animals do not always respond to medicines in the same way that humans do. Therefore, the full risks to the fetus are not known, and a pregnancy Category B medicine should be given to pregnant women only if the healthcare provider believes that the benefits to the woman outweigh any possible risks to the unborn child. In general, diuretics (including metolazone) should not be used to treat high blood pressure during pregnancy
