Poorly safe. Evaluate carefully.
Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives).

Seemingly a sympathomimetic drug with poor effect on Migraine relief.

On latest update relevant data on breastfeeding was not found.

Other medication for Migraine relief like Triptans, Ibuprofen, Diclofenac and Ketorolate are more effective and at a lower risk for breastfeeding than Isometheptene.
