Took one 500mg levaquin last night for sinus infection, sore throat, cough. Awoke several times during the night because my eyes were tearing, and felt "sticky", but did not get out of bed because I was too tired. At 5 a.m. I finally went to look in mirror, and my eyes were red and puffy, & my face was swollen. I felt dizzy and almost fainted. My legs also ached badly around the thigh/knee area, and it was painful to walk the stairs. I had some chest pains on and off during the day, and my rt. eye is still hurting. I am now on benadryl. My doctor wants me to take prednisone, a steroid, but at this point I am afraid to take any more prescriptions. The only reason I agreed to the levaquin is because I had taken it once in the past. 1999 according to my dr. He said he has noticed cases of patients who have a reaction to it the second time around. I am through with antibiotics. These side effects are too scary. I would rather have the sinus infections.
