Drugs to AVOID While Breastfeeding
As your favourite pharmacist, this is something I always educate nursing mothers on.
Your breast milk is powerful, it nourishes, protects, and strengthens that special bond with your baby. 💞
But did you know that some medications can pass into your milk and harm your baby?
Here are 10 drugs to avoid (or only use under strict medical guidance):
1. Chloramphenicol
Can suppress your baby’s bone marrow — potentially life-threatening.
2. Tetracyclines
May discolor baby’s teeth and affect bone development.
3. Aspirin (High doses)
Linked to Reye’s syndrome ,a rare but serious illness in babies.
4. High-dose / IV Metronidazole
Can cause gastrointestinal upset and toxicity in babies.
5. Amiodarone
Affects thyroid function and can impact your baby’s heart.
6. Methotrexate & Cyclophosphamide
Very toxic cancer drugs — strictly not for breastfeeding mothers.
7. Ergotamine / Bromocriptine
Reduces milk supply + risk of seizures in babies.
8. Isotretinoin (Accutane)
Highly teratogenic ,absolutely contraindicated.
9. Lithium
Easily builds up in baby’s system, leading to potential toxicity.
10. Codeine / Tramadol
Can cause drowsiness, poor feeding, or even breathing problems.
✅ Always consult your pharmacist or doctor before taking any drug including over-the-counter (OTC) drugs.
