Read the FAQ explanation of Comprehensible InputReal Context
An antibiotic is a medicine that inhibits the growth of or destroys bacteria. It is used to treat bacterial infections such as sinusitis, pneumonia, or urinary tract infections, and it is prescribed by a doctor after careful diagnosis. Antibiotics do not work against viruses, so they are not appropriate for colds or the flu. Overuse or stopping a course early can promote antibiotic resistance, which makes future infections harder to treat. Some antibiotics are broad-spectrum, affecting many kinds of bacteria, while others target specific species. Side effects can include upset stomach, rash, or allergies. Take the full course as prescribed and avoid sharing antibiotics with others.
Usage Reminders
- Take exactly as prescribed.
- Finish the full course even if you feel better.
- Antibiotics do not treat viruses.
- Do not share antibiotics with others.
- Ask about possible side effects and interactions with other medicines.
Common Misconceptions
- Antibiotics cure viruses like colds and the flu
- More antibiotics are better; you should always take the strongest one
- You can stop as soon as you feel better
- Every infection needs an antibiotic
- Antibiotics have no side effects
