 [ Symptoms ] i had strep about 2 weeks ago i finished the azithromycin 5 days ago my throat is sore again should i get retested [ Disease ] yes and have a throat culture not a rapid strep test the culture is more accurate many times a failure of azithromycin is because it was incorrect prescribed instead of the standard z pack dose of two pills the first day and then one pill per day for the next four days strep should be treated at a higher dose two pills per day for the entire five days
