What medication is appropriate for a lactating woman diagnosed with migraine headaches who wishes to continue breastfeeding?

Sumatriptan is a medication that is considered safe for use in lactating women who experience migraine headaches. As a selective serotonin receptor agonist belonging to the triptan class, sumatriptan is effective for the acute treatment of migraines. Studies have shown that it has minimal levels in breast milk and that its use does not pose significant risks to a breastfeeding infant.

In contrast, some other treatments for migraines can have potential risks when it comes to lactation. Ergotamine, for instance, can inhibit lactation and may have adverse effects on a nursing infant, making it an inappropriate choice. While ibuprofen and acetaminophen are generally safe for treating mild to moderate headaches and are often used in breastfeeding women, they may not provide adequate relief for the specific symptoms and intensity of migraine headaches compared to sumatriptan. Thus, sumatriptan stands out as the most suitable option for a lactating woman who needs effective migraine management while continuing to breastfeed.
