Bacterial Infection
"Every time I get a sinus infection I ask for Doxy it clears me up in a few days. I don&#039;t have any bad side effects, guess I&#039;m lucky. I would recommend this medicine highly for sinus infections since it works so fast. I have to work and don&#039;t have time to be sick, I&#039;m also a single mother and can&#039;t be down too long and this medicine never let&#039;s me down!"
