Eli5 – why do you take antibiotics as a course and not all at once?

960 views

I’ve just started an antibiotics course which is 4 times a day for 10 days and that got me wondering if they would be just as effective if I took them all and why not.

It isn’t the antibiotics that cure the infection. It’s the body’s immunity system but the immunity system takes time to ramp up about ten days. The antibiotics are to keep the germs at bay while the immunity system is ramping up.
