Hi guys. If there's one take away for me about the whole subject of ototoxic drugs, it's that it would be wise to proceed very cautiously with any medication one is considering. My tinnitus started with a single 25 mg dose of a supposedly relatively benign drug called Promethazine. I later discovered it can be prescribed in much lower quantities, so I would most likely have much less severe tinnitus had I done a lower dose instead.
It seems to me that people who end up with tinnitus from taking any kind of medication already had a susceptibility to it. And people who already have tinnitus end up with unusual susceptibility to just about all kinds of drugs. So when considering any kind of medication, why not start slowly with lower doses, and see if an unusual susceptibility manifests itself quickly? Which it turn might ward off catastrophic drug-induced tinnitus (as has been reported by many on this forum). I think there's a big difference between prudent caution and paranoia.
