I was an Antibiotic called Amoxocillen 800 miligrams. My doctor said that was the only bottle that he would prescribe me, he did not tell me why. So I was wondering if your body can get used to an Antibiotic, like a tollerence kind of thing. I used to have really bad acne and thats why he prescribe it to me. The Antibiotic really helped me with it and you could really tell if i had not taken it the night before. so the question is: Can i keep taking them???
