Breastfeeding: Is Prozac safe while breastfeeding?

My family physician and family therapist have prescribed Prozac. However, I am breastfeeding my seven-week-old son and am concerned about the side effects. My doctor says that the drug won't have any effects on my baby, yet the pharmacist read the information from the manufacturer stating the opposite. Should I stop nursing?

Prozac (fluoxetine) is an antidepressant. It is excreted in breast milk. Peak levels occur in human milk within six hours. Fluoxetine is readily absorbed, has a long half-life and may accumulate in the infant. One study reported increased fussiness, crying and severe colic in babies whose moms used this medication.

If you do decide to use this medication to treat depression while nursing, you may want to discuss having your baby's doctor monitor blood concentrations of this drug.

Because of possible side effects associated with Prozac, nursing mothers may want to discuss using Zoloft (sertraline) with their doctor.
