how long do antibiotics augmentin stay in your system
This came straight from the doctor, so that's reliable. Most antibiotics are designed to stay in your system at a therapeutic level for 7 to 10 days. That means that they are actually killing bacteria. However, the effects on your body after finishing the full course of the drug, can last up to 6 months.t depends on the specific antibiotic. The half-lives vary. Name one. I just had a relative with pneumonia, and the doctor gave him a strong (5 day)antibiotic, and said it would stay in his body for several days after he finished his last dose.
