Hi all, I've been trying to work out what happened 4 months ago for me to suddenly get severe tinnitus with no decline in volume yet. The only thing that happened is that I stopped taking antihistamines (phenergan 50mg), and I increased in Amitriptyline to 200mg. Initially I thought it was the increase in Amitrptyline that brought on tinnitus but I swapped over to another medication for a week and there was no difference so went back on it. The only other thing that happened is that I stopped taking phenergan. Could the tinnitus be the result of allergy related inflammation? I read that phenergan can be ototoxic so I am scared to go back on it, but could it potentially help? I'm now also on Nasonex nasal spray. Could this work also?
