Risk Summary

Sumatriptan is excreted in human milk following subcutaneous administration (see Data). There are no data on the effects of sumatriptan on the breastfed infant or the effects of sumatriptan on milk production.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for IMITREX injection and any potential adverse effects on the breastfed infant from sumatriptan or from the underlying maternal condition.

Clinical Considerations

Infant exposure to sumatriptan can be minimized by avoiding breastfeeding for 12 hours after treatment with IMITREX injection.

Data

Following subcutaneous administration of a 6 mg dose of IMITREX injection in 5 lactating volunteers, sumatriptan was present in milk.
