Hello! I was wondering if anyone else's tinnitus started from taking an H2 blocker, such as Zantac/Ranitidine...I have GERD and I was taking a PPI for 8 months.. I started transitioning off of it and my doctor recommended Zantac, 300 mg daily. I have never had tinnitus in my life, but a few days after starting the Zantac, I started waking up in the middle of the night to very loud ringing in my ears. I thought it was just a freak side effect but unfortunately, it continued. Now, everytime I am in a quiet room, or when I lay down in bed at night, I'm bombarded by an extremely loud ringing in both of my ears. It's very unnerving... I called my doctor and two pharmacists to ask about it and all of them said that tinnitus "isn't listed" as a side effect of Zantac and they've never heard of it. My doctor told me to lower my dose of Zantac, so I did, but I still have the tinnitus.... I'm scared that it's permanent. Is it possible that it's a vitamin deficiency like B12? Does anyone have that? Thank you for your help and support. This is very worrisome.
