Most medicines should be taken with plain water, because water does not interfere with absorption.
Examples of medicine types that must be taken with water:
- Antibiotics like azithromycin, amoxicillin (milk can reduce absorption for some)
- Painkillers like ibuprofen, diclofenac
- Paracetamol
- Thyroid medicines (e.g., levothyroxine)
- Iron supplements (milk blocks absorption)
- Antacids (some react with calcium)
- Blood pressure medicines
- Diabetes tablets
Rule: If unsure, always take with water because it is safest and non-reactive.
Medicines Usually Taken WITH MILK
These are medicines that can irritate the stomach and become gentler if taken with milk.
Common categories:
- NSAIDs like Ibuprofen (if doctor says it’s okay) — milk helps reduce stomach irritation
- Some antibiotics like doxycycline — milk reduces stomach upset but may reduce absorption slightly (doctor specific)
- Steroids (e.g., prednisolone) — often recommended with milk/food to protect stomach
- Vitamins that need fat, such as Vitamin D, A, E, K — milk improves absorption
- Calcium tablets — ok with milk since both contain calcium
➡️ Rule: Milk is mainly used to protect the stomach or improve absorption of fat-soluble vitamins.
| Medicine type | Take with | Why |
| Painkillers | Milk or food | Protect stomach |
| Antibiotics | Water | Calcium interferes |
| Vitamins (D, A, E, K) | Milk | Better absorption |
| Iron | Water | Milk blocks iron absorption |
| Thyroid meds | Empty stomach + water | Works best |
| Steroids | Milk or food | Prevent acidity |
Medicines You Should NEVER Take With Milk
Because calcium reduces absorption, avoid taking these with milk:
- Iron supplements
- Thyroid medication
- Some antibiotics like tetracycline/ciprofloxacin
- Ayurvedic churnas with mineral content (calcium interference)
