Is it a problem if I take certain medications while breastfeeding?

The following medications should not be taken while breastfeeding:

  • Anti-cancer medications (antineoplastics)
  • Drugs of abuse (e.g. alcohol, cocaine, heroine)
  • Certain anti-seizure medications (e.g. Phenobarbital, ethosuximide, and primidone )
  • Ergot alkaloids
  • Radiopharmaceuticals

If you have a question, you should contact your doctor and ask whether the medication you are taking is safe while breastfeeding.
