Dear Sara, How fortunate your friend to be able to call you for information. It is often difficult for moms to know what is truth & what is fact. A book you might want to obtain is MEDICATIONS & MOTHER'S MILK by Thomas Hale. Medela has it for less than $20. Dr. Hale says Medroxyprogesterone is approved by the AAP for use in breastfeeding mothers. Phil Anderson, a pharmacist, spoke at the May LLL convention in Fremont, CA. One can call the 900-288-8273 for a nominal fee to receive up-todate information on medication & breastfeeding. Sylvia Boyd, CLE, PT, ACCE mailto:[log in to unmask]
