What to do if you miss a dose of Augmentin

Missing a dose of Augmentin (Amoxicillin/Clavulanate) is common — most people will skip a dose at some point during a course. The right action depends on how long since the missed dose and whether Augmentin is taken event-driven or daily at 500/125mg, 875/125mg, 1000/62.5mg. The wrong action — doubling up — is not recommended.

For daily Augmentin

If Augmentin is taken daily for a chronic condition, take the missed dose as soon as you remember, unless it is almost time for the next scheduled dose. In that case skip the missed dose and continue normally. According to the prescribing information for Amoxicillin, Clavulanate, two doses should never be taken close together to "make up" for a miss.

For event-driven Augmentin

If Augmentin is used as needed (not on a fixed schedule), there is no "missed dose" in the conventional sense — simply take the planned dose when needed and observe the recommended gap before re-dosing. Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), but is hydrolysed by beta-lactamase enzymes produced by some resistant bacteria.

Frequently asked questions

Should I double the dose if I missed Augmentin? ▾

No. Doubling doses of Augmentin to compensate is not recommended at any 500/125mg, 875/125mg, 1000/62.5mg strength and increases the risk of side effects without improving efficacy. Take the next scheduled dose normally.

How many missed doses are too many? ▾

Occasional missed doses of Augmentin are usually inconsequential. Repeated missed doses can compromise the therapeutic effect — for chronic conditions like those treated with Antibiotics, consistent dosing matters. If adherence is hard, discuss reminders, simpler schedules or alternative formulations with the prescriber.
