Drugs that require careful monitoring by a physician when taken while breastfeeding
Whether these drugs and medications are safe to take while breastfeeding depends on many factors: the dosage, age of infant, duration of therapy, and timing of dosage and breastfeeding. Consult a physician knowledgeable about drugs during breastfeeding if you need to take any of the following medications long-term.
alcohol | general anesthetics* | morphine |
antidepressants | indomethacin | oral contraceptives |
aspirin | isoniazid | Paxil |
codeine | lithium** | phenobarbitol |
Demerol | metoclopramide | Prozac |
ergots | metronidazole (Flagyl)*** | Valium |

* It is safe to breastfeed six to twelve hours after most general anesthetics. ** Some authorities consider lithium absolutely contraindicated while breastfeeding; others believe lithium can be used cautiously, as long as blood lithium concentration in the baby is monitored. *** Authorities recommend giving the mother a single two-gram dose and having her discontinue breastfeeding for only twelve to twenty-four hours. |
