Answer by DrLact: About TFP usage in lactation

Limited information indicates that maternal doses of TFP up to 10 mg daily do not affect the breastfed infant. Very limited long-term follow-up data indicate no adverse developmental effects when other phenothiazines are used alone. Because there is little published experience with TFP during breastfeeding, other antipsychotic agents may be preferred, especially wile nursing an newborn or preterm infant.

TFP Side Effects in Breastfeeding

One infant was breastfed from birth during maternal TFP 10 mg daily in addition to clonazepam 0.25 mg daily and valproic acid 500 mg daily. No adverse effects in the infant were reported by the mother (follow-up time unspecified).[2] One mother began taking TFP (dosage unspecified) 2 months postpartum while breastfeeding her infant. She also started olanzapine 10 mg daily, paroxetine and procyclidine (dosages unspecified). The infant experiences no adverse reactions.[3] Two mothers taking TFP 5 and 10 mg per day orally breastfed their infants from 1 week and 8 weeks of age, respectively. Mental and psychomotor development were measured at various time up to 30 months of age and were found to be normal.[1]

TFP Possible Effects in Breastfeeding

Phenothiazines cause galactorrhea in 26 to 40% of female patients.[4][5] Hyperprolactinemia appears to be the cause of the galactorrhea.[6][7][8] The hyperprolactinemia is caused by the drug's dopamine-blocking action in the tuberoinfundibular pathway.[9]
