Can multiple doses of antibiotics cure an infection?
if there is some improvement then the course can be repeated
HI, thanks for using healthcare magic
Antibiotics have different dosing schedules. This means that the effective course of one antibiotic differs from another.
Eg azithromycin is commonly used for 3 to 5 days but many other antibiotics require 7 days or more.
Repeated courses of an antibiotic can be used if an infection does not respond to the first course but if possible, it would be best to take a swab or some sort of sample of the infected area if possible, if there is no response to the first antibiotic course.
The sample can be sent to the lab to determine the exact bacteria causing the infection and also to find which antibiotics work and which ones do not.
In some cases, when an antibiotic does not work, it means that the person/infection is resistant to the medication/antibiotic and a different antibiotic should be used
So if you have a persisting infection with no improvement at all, it may be best to consider an alternative.
If there is slight improvement then the course of the original antibiotic can be extended/repeated
I hope this helps, feel free to ask any other questions
