Possible Effects on Lactation

Loxapine can elevate serum prolactin.[2] The hyperprolactinemia is caused by the drug's dopamine-blocking action in the tuberoinfundibular pathway.[3]

The prolactin level in a mother with established lactation may not affect her ability to breastfeed.

Alternate Drugs to Consider

Haloperidol, Olanzapine
