Antibiotics like penicillin or amoxicillin are commonly prescribed to fight infections, but have you ever wondered how they actually work?
Normally, your white blood cells can handle small amounts of bacteria on their own, but when harmful bacteria multiply faster than your immune system can keep up, antibiotics help by killing the bacteria and stopping their spread.
Here are some additional fast facts:
📈 Not all conditions require antibiotics — some just have to run their course.
🤧 Antibiotics are ineffective against viral infections like colds and the flu.
✅ Taking antibiotics only when needed prevents side effects and resistance.
⏰ It may take days after your first dose to start feeling better.
🗓️ Always finish your full course of antibiotics even if you feel better early.
🤢 Common side effects include nausea, diarrhea and yeast infections.
⚠️ Seek medical help if you experience hives, swelling or difficulty breathing.
