Why the reason matters
Antibiotics treat certain bacterial infections. They do not treat colds or flu caused by viruses. A clinician decides whether an antibiotic is appropriate; having a fever alone does not identify the cause. Unnecessary use contributes to resistance.
Ask before the first dose
- What infection is this medicine intended to treat?
- How should I take it, and for how long?
- Do my other medicines, allergies, pregnancy or breastfeeding affect the choice?
- What should I do if I miss a dose or develop side effects?
Follow the individual instructions
Use the prescription and product leaflet, and ask a pharmacist about anything unclear. Do not borrow someone else's antibiotics or share yours. A previous prescription is not a treatment plan for a new illness.
When to get help
Contact your clinician if symptoms worsen or side effects concern you. Breathing difficulty or swelling of the mouth or throat can indicate a serious reaction: seek emergency care immediately. This article does not select an antibiotic or prescribe a dose.
