The length of treatment varies depending on the specific infection and the age of the individual receiving treatment It is important to note that Azirun is not always prescribed for a duration of 3 days For most bacterial infections a 3day course consists of a single 500 mg dose However there is an alternative dosing regimen where a 500 mg dose is given on the first day followed by a reduced dose of 250 mg from day 2 to day 5 In certain cases such as genital ulcer disease a single 1 gram dose may be administered To ensure optimal results and prevent the development of antibiotic resistance it is crucial to strictly adhere to the treatment regimen recommended by your healthcare professional
