What this trial studies

This observational study aims to assess the transfer of galcanezumab, a medication for migraines, into the breastmilk of nursing mothers. It will involve collecting milk samples from 30 women aged 18-45 who are postpartum and experiencing migraines. The study will also evaluate the health outcomes of both mothers and their infants, including growth and development, over a period of up to 12 months. Participants will complete questionnaires and provide health records to help analyze the effects of the medication on breastfeeding.

Who should consider this trial

Good fit: Ideal candidates are women aged 18-45 with a diagnosis of migraine who are between 14 days and 9 months postpartum and still nursing.

Not a fit: Patients who are not breastfeeding or have contraindications to breastfeeding or galcanezumab will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide critical insights into the safety and effects of migraine treatment in breastfeeding mothers, potentially improving their quality of life.

How similar studies have performed: While studies on migraine treatments exist, this specific focus on breastfeeding and galcanezumab is relatively novel and has not been extensively tested.
