Precautions
Conditions predisposing to seizures, presence of coronary risk factors, cardiac arrhythmias, renal or hepatic impairment, elderly, pregnancy, lactation.
Lactation: Excreted in breast milk at very low levels; minimize infant to potential exposure by avoiding breastfeeding for 8-12 hours after administration
Pregnancy-Lactation
Pregnancy
Data from a prospective pregnancy exposure registry and epidemiological studies of pregnant women have not detected increased frequency of birth defects or consistent pattern of birth defects among women exposed to sumatriptan compared with general population; in developmental toxicity studies in rats and rabbits, oral administration of sumatriptan to pregnant animals was associated with embryolethality, fetal abnormalities, and pup mortality; when administered by intravenous route to pregnant rabbits, sumatriptan was embryolethal
However, possible disease-associated maternal and/or embryo/fetal risk reported; several studies have suggested that women with migraine may be at increased risk of preeclampsia during pregnancy
Lactation
Sumatriptan is excreted in human milk following subcutaneous administration; there are no data on effects of sumatriptan on breastfed infant or effects of sumatriptan on milk production; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for injection and any potential adverse effects on breastfed infant from sumatriptan or from underlying maternal condition
Infant exposure to sumatriptan can be minimized by avoiding breastfeeding for 12 hr after therapy
