What to do if you miss a dose of Amoxicillin
Missing a dose of Amoxicillin (Amoxicillin) 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 Amoxicillin is taken event-driven or daily at 250mg, 500mg, 875mg, 500/125mg, 875/125mg, 1000/62.5mg. The wrong action — doubling up — is not recommended.
For daily Amoxicillin
If Amoxicillin 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, two doses should never be taken close together to "make up" for a miss.
For event-driven Amoxicillin
If Amoxicillin 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, which prevents the cross-linking of peptidoglycan layers and triggers bacterial autolysis.
Frequently asked questions
