Protocol
Use the prescribed antibiotic plan, not leftovers from a similar illness
Similar symptoms are not a prescription match.
When it fits
- An antibiotic has been prescribed or leftover tablets seem tempting.
When to avoid it
- Antibiotics do not treat viral infections, and this card cannot diagnose the cause of symptoms. Serious reactions or rapidly worsening symptoms require urgent medical help.
Why it matters
Take an antibiotic exactly as prescribed for the current illness. Do not borrow another person's supply, share yours or keep leftovers as a future treatment plan. Ask a healthcare professional about concerns, side effects and any proposed change rather than independently shortening, extending or restarting treatment.
Steps
- Confirm the current medicine, instructions and any uncertainty with the prescriber or pharmacist.
- Keep treatment changes tied to professional advice.
- Ask a pharmacist how to dispose of unused medicine locally.
An example
A previous course is not restarted merely because a sore throat feels familiar.
Check your result
The medicine is being used for the current prescribed purpose with understood instructions.
Keep this limit in mind
- Antibiotics do not treat viral infections, and this card cannot diagnose the cause of symptoms. Serious reactions or rapidly worsening symptoms require urgent medical help.
