The essentials
When are antibiotics needed?
The short answer
Antibiotic decisions depend on infection type, severity and individual risk. Do not use someone else’s prescription or leftover antibiotics.
Care and treatment approach
When prescribed, take antibiotics exactly as directed. Contact the healthcare team about side effects or treatment concerns rather than changing the plan yourself.
CDC ↗Clinical assessment note
Unnecessary use can cause adverse effects and contribute to resistance. Necessary treatment must not be delayed either; a clinical decision cannot rest on an online article alone.
NHS ↗Bring a question to your appointment
What does this mean for my test or care plan?
International evidence, local decisions
Each source’s country is identified. Vaccine access, reimbursement, isolation and reporting rules vary. Use current guidance and your clinician’s advice in your country; English does not imply UK or US eligibility.
