The length of treatment is determined by the specific infection being addressed and the age of the individual receiving treatment Its worth noting that Azifed is not universally prescribed for a fixed duration of three days In the majority of cases involving bacterial infections a single 500 mg dose is administered daily for three days An alternative regimen involves a 500 mg dose on the first day followed by a 250 mg dose from the second to the fifth day In certain instances such as genital ulcer disease a single dose of 1 gram may be recommended Consequently it is essential to adhere to the treatment plan outlined by your healthcare provider This ensures the most effective use of Azifed and a successful resolution of your infection
