Dose and duration are chosen for the infection; irregular use disrupts treatment.

Take the medicine at the prescribed times and for the prescribed duration, and do not share it. If side effects occur, contact a doctor or pharmacist instead of changing or replacing it on your own. Leftover antibiotics are not suitable for a future illness.
Medical principle
Effective prevention usually involves simple repeated habits: correct handwashing, food safety, appropriate vaccination and responsible medicine use. Excessive disinfection or unnecessary antibiotics do not replace these principles.
Practical steps that may help
- Wash hands with soap and water at key times, using suitable alcohol sanitiser when unavailable.
- Separate raw and cooked food, refrigerate perishables promptly and keep surfaces clean.
- Keep vaccination and medicine records and review them at routine visits.
When should you seek medical care?
Possible poisoning, a severe reaction after medicine or vaccination, significant fever and dehydration, or signs of severe infection need prompt assessment.
