Is Amantadine safe while breastfeeding?

Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Amantadine. The text below is quoted from that source — it is not our own verdict.

Summary of use during breastfeeding

It is probably best to avoid amantadine during breastfeeding because of its potential negative effect on lactation. An alternative medication is recommended.

Effects on milk supply

Amantadine is a dopamine agonist. Clinical studies using amantadine dosages of 100 mg 2 or 3 times daily have demonstrated a decrease in serum prolactin and decreased galactorrhea in patients taking dopaminergic neuroleptic drugs such as phenothiazines, haloperidol and loxapine.[1,2] No studies have been reported on the effects of amantadine on the milk supply in nursing mothers. The maternal prolactin level in a mother with established lactation may not affect her ability to breastfeed.
