  • For the majority of prescription drugs, only a small amount of medication enters the milk
  • It is very rare that a mother would need to avoid the pharmacological benefits of a medication to breastfeed or stop breastfeeding to take a medication


  • If the drug does not get into the blood it cannot get into the milk
    • Example: eye drops


  • Some drugs do not get into the milk:
    • Heparin (prevents blood clotting)
    • Interferons (used for many illnesses)
    • Ketorolac (short-term pain relief)
    • Diazepam (anti-anxiety medication)


  • Some drugs can get into the milk, but the baby does not absorb the drug:
    • Pantoprazole (used for gastro-esophageal reflux disease (GERD))
    • Some antibiotics
      • Gentamycin
      • Vancomycin


  • Some drugs are present in such low levels in the mother’s milk because the drug is mostly present elsewhere in the body:
    • Antidepressants
      • Citalopram
      • Sertraline


Consider the Following Before Taking Medications While Breastfeeding:

  • Use the safest medication
    • Some medications have alternatives that are safer for use while breastfeeding
  • Talk to your doctor or pharmacist about the best time to take medications to minimize the effects on your baby
  • Watch for potential side effects in your infant
    • Fussiness
    • Rash
    • Changes in feeding or sleeping


Medications Have Less Impact on Breastfed Babies Who Are:

  • Heavier
  • Older
  • Born healthy and full-term
  • Take solid foods at an appropriate age, as well as continuing breastfeeding
