Drug interactions: when meds fight

📖 Lesson ──▶ 🎯 Quiz — pick the translation ──▶ ✅ Lesson done

Two harmless meds together can be poison. Classic: anticoagulants (Warfarin, Marcumar) + ibuprofen/aspirin = bleeding. Grapefruit + statins = overdose. Antibiotics + milk = no absorption. Sleeping pill + alcohol = respiratory arrest. Rule: every new med — tell the pharmacist WHAT you already take, including herbs and vitamins. St. John’s wort kills almost all pills.

⚠️ Grapefruit is the interaction champion: one fruit cancels or boosts 85+ meds for 3 days. Not a “vitamin” — a pharmacological agent.
