About this medication
- Amoxicillin is an antibiotic used to treat infections caused by certain bacteria.
- It works by stopping bacteria from building their protective outer wall, which kills the bacteria causing your infection.
- It only works against bacterial infections and will not help with colds, flu, or other infections caused by viruses.
Treats susceptible bacterial infections; it does not treat viral colds.

Other medicines and products
- This medicine can be taken with or without food, though taking it with food may help reduce stomach upset.
- Tell the Care365 care team about all other medicines and supplements you take, since amoxicillin can interact with certain other drugs.

Missed doses, storage and accidental exposure
- If you have the liquid suspension: after it is mixed by the Care365 care team, store it at room temperature and keep the bottle tightly closed. Throw away any unused liquid after the number of days noted on the pharmacy label, since it does not stay effective indefinitely once mixed.
- Store unmixed granules at room temperature.
- Keep this medicine out of the reach and sight of children.
- Return unused or expired medicine to your pharmacy for safe disposal rather than throwing it in household trash.
Follow your own product’s missed-dose instructions. If you are unsure, ask the Care365 clinical team before taking an extra dose. Contraceptives, injections and modified-release medicines may need a specific plan.
Keep the original packaging and follow its storage, expiry and disposal instructions. Keep medicines away from children and pets. Ask about refrigeration, after-opening limits and safe sharps disposal when relevant.
For suspected overdose or accidental swallowing, contact poison control or urgent medical care promptly. Call emergency services for breathing difficulty, collapse or a seizure.
Key points to remember
- Complete the full course of antibiotics as prescribed, even if you feel better, to help fully clear the infection and reduce the risk of antibiotic resistance.
- Do not save leftover antibiotic for future infections or share it with anyone else.
- Tell every healthcare provider, including dentists, about any past allergic reactions to penicillin-type antibiotics.
- If your symptoms have not improved within a few days, follow up with your healthcare professional rather than stopping treatment on your own.
