i once went to see this girl that had a bottle of amoxicillin 750mg on the table.. i was so surprised it was out in the open, i asked if she was ok, and if she knew what that was.. she had no clue, she said the doctor told her to take it.. the bottle was almost empty but i didnt do anything that was not with a cover.. i had been tested since then, i didnt catch anything.. there are lots of bacterial infections treated with amoxicillin, so who knows..
