why do you have to complete antibiotic course

by Wilfredo Lehner 3 min read

So why is it that your doctor recommends finishing your course of antibiotics? It's because taking them regularly until the prescription is complete helps ensure that all of the illness-causing bacteria are killed or prevented from multiplying. Even if your symptoms go away, the bacteria may still be present in your body.

If you stop treatment before the antibiotic cycle is over, the remaining bacteria can continue to multiply. If these bacteria become resistant to the antibiotics, they can potentially do even more harm. It may take longer for you to recover from your illness, and your physician may have to prescribe more medication.Oct 2, 2016
