How long does it take a ten day course of augmentin 875-125 to leave your system? i finished the medication seven days ago.

Definitely out: The medication has quite a short half-life, which is why it is taken 2x a day- since the first dose in the morning wears away, then you need a second dose. Generally we think of 5x the half-life as a 'complete' elimination of the drug - so you are well beyond that... it would have been totally gone after a couple days. If you're having symptoms of some kind though, you should check with a doc.
