How long does Amoxicillin and Clavulanate Potassium stay in your body?
The elimination half-life of amoxicillin and clavulanate potassium is about 1 hour (roughly 61 minutes) — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. The half-life is longer in newborns and young infants and in people with reduced kidney function, because amoxicillin is cleared mainly unchanged by the kidneys; it has no active metabolite.

Frequently asked questions
- How much does Augmentin '500' cost?
- Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.04 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
- Is there a coupon or discount for Augmentin '500'?
- pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Augmentin '500'. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay.

What people report to the FDA about AMOXICILLIN AND CLAVULANATE POTASSIUM
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 4,716 reports naming AMOXICILLIN AND CLAVULANATE POTASSIUM — the active ingredient in Augmentin '500', and the FDA flagged 80% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- diarrhoea430 reports
- dyspnoea361 reports
- nausea278 reports
- pyrexia266 reports
- fatigue253 reports
- rash248 reports
- pruritus242 reports
- vomiting236 reports
Read these as a signal, not a rate. A report does not mean AMOXICILLIN AND CLAVULANATE POTASSIUM caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.
