Effects on Lactation and Breastmilk

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.
