I have been on metoprolol tartrate for quite a few years. I have what they call "burning mouth syndrome" for at least 6 years and have read that metoprolol is one of the blood pressure medications that can cause this. I can' t convince my cardiologist, but want to taper off for a few weeks to see if this is the culprit. I have a-fib and on Eliquis for this. The metoprolol is to keep my heart rate at an acceptable rate. I would like to hear from anyone who has had this burning mouth side efftect and if the metoprolol was the cause. Thanks for any help.
