The BP medication; Metoprolol gave me tinnitus. I was given something else in it's place, but hasn't completely gone away. I've also read others reviews of taking Metoprolol and found that they also developed tinnitus while using it. I found that it may never fully go away. I did just order a supplement strictly for tinnitus sufferers; called Synapse XT and given an A+ rating. Probably wasted my money once again! I bought one bottle, but usually these companies want you to buy at three to guarantee that they will work.
