Zolmitriptan Pregnancy and Breastfeeding Warnings
Zolmitriptan Pregnancy Warnings
The manufacturer lists miscarriage under adverse effects with a frequency of "rare".
Zolmitriptan has been assigned to pregnancy category C by the FDA. Animal studies have revealed evidence of embryolethality, and fetal abnormalities. Animal studies have also revealed maternal toxicity at high doses. There are no controlled data in human pregnancy. Zolmitriptan should only be given during pregnancy if the potential benefit justifies the potential risk to the fetus.
Zolmitriptan Breastfeeding Warnings
There are no data on the excretion of zolmitriptan into human milk. Because many drugs are excreted into human milk, caution is advised if zolmitriptan is to be administered to a nursing woman.
Animal studies have reported milk levels equivalent to maternal plasma levels at one hour after dose administration, and four times higher than plasma levels at four hours after dose administration (in the milk of lactating rats).
