sinusitis
"I've used Zithromax 6-Paks for years to treat chronic sinus infections. They always work and have virtually no side effects for me. I have noticed that I need to take the treatment twice for a persistent sinus infection. Usually, one treatment does it. Azithromycin is the ONLY antibiotic that does NOT give me terrible side effects such as stomach aches, cramps, headaches, dizziness, "brain fog"."
