For Sinusitis "I've used Zithromax 6-Packs 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'."

For Bacterial Infection "Severe anxiety and nervousness, horrible diarrhea, awful stomach ache, intense nausea, freaky nightmare, horrific headache. I only took 2 pills, they were 250 mg apiece. Don't recommend whatsoever. Now I'm feeling like death, wondering when the effects will wear off."

For Chlamydia Infection "The nurse gave me two Zithromax pills to take for chlamydia. An hour later, my stomach was killing me, and I had diarrhea! I can’t even finish my meals, halfway through my meals, I feel nauseous. I am also very bloated, and I get headaches, dizziness, discharge, and itchiness! Use a condom! You don’t want to go through this."

For Sinusitis "I am one of the few that have not had a good experience. High anxiety because my heart won't slow down, bad headache, little nausea, and loose stool. I'm going tomorrow to get different antibiotics."
