I accidentally took a second daily 24-hour Claritin on Wednesday morning after I forgot I had already had one a few minutes earlier. My Tinnitus spiked sharply on Thursday morning (including several instances of "fleeting" tinnitus) and is still driving me berserk. I've never had a problem with Claritin before, but I've read it's ototoxic, and the directions say not to take more than one every 24 hours. Is my T spike just a coincidence? Am I worrying over nothing?
