why do you have to finish your antibiotics course

Here’s why you should ALWAYS finish your antibiotics:

• 1. Antibiotic resistance When you don’t finish your antibiotic, those “bugs” still left in your body can develop resistance to that antibiotic. If so, you may get sick again and it will be even harder to treat because that antibiotic may not work as well. You could potentially spread this to others as well.
• 2. Antibiotic effectiveness

Should you always finish your full course of antibiotics?

Until now, the advice has always been to finish taking a prescribed course of antibiotics, even if you already feel better (unless a doctor tells you otherwise). Most experts believe that if you stop taking an antibiotic part way through a course, the bacteria you're trying to get rid of can become resistant to the medication.

If the latter is true, the persistent population in your body that is causing your recurrent infection could well be resistant to that first set of antibiotics, meaning those antibiotics may well be useless against your infection.

The original article bases its findings on a very limited set of clinical trial data for some specific infections.

Do antibiotics cause bacteria to die?

Why do we have to take antibiotics?

The idea that you have to take all the antibiotics you’re prescribed is based on the assumption that all the bacteria causing the infection have to be killed, so the surviving minority don’t become resistant. In fact, for most otherwise healthy people, significantly reducing, but not necessarily totally eliminating, the bacteria causing the infection allows the body’s natural defences to take over and mop up the remaining few.

What are regimens based on?

Regimens are based on clinical studies done when the drugs were first tested, Boucher said. Newer, more refined studies often reveal more effective lengths that strike the balance between killing the bacteria causing an infection and not flooding the environment with more antibiotics.

How long does it take for an antibiotic to kill a bacteria?

The original theory was this: Treating bacterial infections with an antibiotic kills those bacteria, but this may take a week or more to accomplish. If you stop treatment early, you have only killed the weaker of the bacteria, those bugs most readily wiped out by the antibiotic. The ones leftover are the tougher bacteria, which would have been killed if the treatment continued but now, in the absence of antibiotics, have room to multiply and pass their genetic-based resilience to their progeny. Next time around, the infection is that much tougher.
