For Sinusitis "The medicine worked great to counter my sinusitis, and I was breathing better after just one dose. But the side effects are almost unbearable: nausea, dizziness, headache, lightheadedness, dry mouth, and constipation. The dizziness and lightheadedness kick in after about an hour of taking the pill and last for about 5 hours. Very difficult to function normally and trying to work while taking this medicine."

For Bacterial Infection "The next day after taking it, I began to have twitching in my hands and fingers, dizzy, could not walk a straight line, and was extremely tired, sleeping 20 hours (I usually sleep 6 hours). After being taken off, after 3 days, most of my strength has returned, still a bit lightheaded. Apparently, these effects affect 2% who take the medicine."

For Sinusitis "If you take SSRIs (antidepressants) for anxiety and/or depression, watch it while on this medicine. In addition to the dizziness, lightheadedness, and stomach problems, it might reduce the overall effectiveness of your SSRI."

For Pneumonia "I am on my sixth day of Avelox 400 mg for pneumonia. I have noticed a big change in my breathing, and I do feel better. Still counting down to the last 4. Mostly because after I take it, I start feeling depressed, ill, tired, and still cannot eat or drink much. So I dehydrated to the point that I could not understand what people were saying. Nothing made any sense. That is better now, but still get confused, dizzy, lightheaded when I walk, depressed, and so on."

For Sinusitis "I have chronic sinus infections that are not unbearable...mostly annoying. I was prescribed Avelox recently and am halfway done with my dose. I have had some seriously horrible reactions to this drug. Granted, it is obviously helping with my sinus infection, but the dizziness, nausea, lightheadedness, dehydration, and overall sick feeling are worse than the sinus infection itself. I am glad that I will no longer have an infection in my body, but isn't there another way? This is awful!"

For Pneumonia "I felt good the next day after one pill. My chest felt better, but the side effects scare me. I get quick light-headed and dizzy the whole time on this drug. I could not sleep, I felt very restless. But the medicine cleared up my lungs."

For Sinusitis "Yes, it works! However, the side effects are horrible. Light-headed and majorly dizzy, to the point where I was very uncomfortable driving. This is the 2nd time I've used it and the same results each time. Caused me to call out of work for a whole week until the side effects were gone."

For Sinusitis "The only problem I have with this medication so far is how expensive it is. So far, the only side effects I have had are a light-headed feeling, similar to a feeling of an antihistamine with pseudoephedrine in the mix. I am already starting to feel better."

For Bacterial Infection "This past Wednesday, my right nostril was a little sore, figured I was a little overly aggressive with the allergy early morning blowing. By Friday, 3:30 a.m., I woke up to stabbing pain all on the right side of my face! Swollen, and the tissue was HARD, nasal passage (where the infection started) was 3/4 closed! Today is day 4, my face is pliable again, still a little stiff close to my right nostril, but my lips, cheeks, and eyes feel great, nostril very slightly tender in comparison to Wednesday. This Avelox works, only problem I've had is dry mouth (drinking plenty of water) and a little lightheaded/dizzy, but I'm not driving, so that's okay!"
