The half-life of Amoxicillin is 61.3 minutes. Approximately 60% of an orally administered dose of Amoxicillin is excreted in the urine within 6 to 8 hours.

Antibiotics can take two to three weeks to leave your system. They seem to work overtime to clean up your system even after you stop taking the pills. Also, some antibiotics work longer or shorter depending on the kind. For instance, Neomycin, is not completely absorbed into the blood system and is excreted out through urine and fecal matter. In this case, it is only in the system for 4-5 days.
