I was prescribed this medicine for 10 days due to a cyst like skin infection on my inner thigh. On day 5 My right eye on the left side was very bloodshot. Not sure if its related as I had pink eye a couple weeks ago and thought it was gone. I also have gout and take allopurinol which sometimes causes my eyes to get bloodshot for extended periods. On day 9 I had a headache (throbbing behind my eyes), slight fatigue and that night it felt like I might be getting the flu (aches, nose passageway closing a little). Today has been the worst, still not sure if its related to the meds as this has been the season of the swine flu as well. I have positional vertigo which makes me dizzy sometimes, I've been free of dizziness from the vertigo for 3 years and just started again tonight. My teeth have been sensitive to cold all day too and even though it was 98 degrees outside and 77 in the house I was freezing. Feel a little bit of heart flutters as well. I did miss one dose on day 8. I probably didn't drink enough water with the prescription either. Lastly, I've been a bit stressed from work and an upcoming trip so take these "side effects" with a grain of salt. Either that or my body is week from all the other problems I have. Thankfully I haven't been itchy as others describe.
