Q&A: Can I Take Primidone?
Primidone isn't a strict no-no, but the American Academy of Pediatrics warns that it should be given to nursing mothers with caution. Primidone does cross into your milk in significant amounts, which can lead to a super-sleepy baby who nurses poorly (which can in turn keep her from gaining weight properly). If you take primidone while breastfeeding, you and your doctor will need to pay special attention to baby’s nursing habits and weight gain. Be sure baby actively feeds eight to 12 times every 24 hours.
