I'm a 45 yr-old male in pretty good health. Start Cipro for prostatitis, 500mg x2 / day. Eight days into therapy, starting experiencing tinnitus, tingling in hands & feet, and anxiety++. On day 9, actually experienced a significant facial 'tic'. Stopped drug on day 9; anxiety faded out 95% in less than 2 days, tingling has abated about 1/3 after 4 days, but still remains very noticable (of course, now I'm focused on it). Tinnitus remains at the same level. Have taken Floxin & Levequin several in the past with no adverse effects.
