how long does amoxicillin stay in your system?

Very short half life: In general Ampicillin and it's derivatives have a very short half life and if one stops taking the medicine, it will be out of ones system in a matter of a few days. You should be able to smell it in your urine, when the odor is gone, the medication is likely gone as well.
