Hello and hope you are doing well.
The adult azithromycin dose
is 500-2000 mg in multiple or single
doses. For most infections, azithromycin is taken once daily for a relatively short course of treatment (usually five days). The first dose is often a "double dose," twice as much as the remainder of the doses given. For acute bacterial sinusitis, azithromycin way be taken once daily for three days. So, you may not need any refills for Azithromycin.
