Possible Effects on Lactation
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. 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.
