For Sinusitis "Although there should be no negative drug interaction with this antibiotic and other medication I take daily, I had a severe allergic reaction: swelling of throat and tongue, vertigo and dizziness, bad taste in my mouth (even days after), and vomiting. I'm on my third day of the medication now and still feel sick and 'weird.' My throat and tongue are no longer swollen, but all my muscles hurt, and my skin feels painful, also major headache, and very sleepy."

For Sinusitis "I’ve taken this Azithromycin Dose Pack twice a year for about fourteen years for sinusitis and never had a problem with it, always worked great without any side effects. When I started taking it this time around, the headaches were so bad, and the diarrhea and loose stool are unbelievable, so after four days, I’ve stopped and won’t take the last pill, that’s how bad the side effects are this time. I know one day more for the last pill would be silly to stop, but I just can’t handle the side effects any longer. The brand that the pharmacy gave me this time is a different brand, so that may have something to do with it. The pharmacy I used for years has closed down, so the other one has different pills or brands for the same meds. I’ve always said a pill is just a pill, and it doesn’t matter what brand it is, but after this, I changed my mind completely on that."

For Upper Respiratory Tract Infection "5-day pack took 2. First day, no problem. Second day, 1. Third day, 1. That night, couldn't sleep at all, heart was pounding and skipping, diarrhea, headache, muscle pain from front wrapping around to back, felt anxious, dizzy, felt like I was spinning. Stopped taking. Next day, still had symptoms, can't wait till it is out of my body. Never had trouble with any antibiotics before. This was my first time taking this medicine. I wish I had read side effects before I took it."

On the 6th day, I experienced vomiting, dizziness, stomach cramps, constipation, black stool, hypertension, fast beating of the heart, low energy, hives on my face, headaches, swollen eyelids, and dark circles under my eyes. Day 11 after taking the last dose, still experiencing a fast heartbeat, swelling in my feet, and hives on my face. Low energy."
