Effects on Lactation and Breastmilk

Loxapine can elevate serum prolactin.[1] The hyperprolactinemia is caused by the drug's dopamine-blocking action in the tuberoinfundibular pathway.[2]

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

Alternate Drugs to Consider

Haloperidol, Olanzapine, Quetiapine, Risperidone
