User Reviews for Metoprolol Succinate ER

This medicine works very well to keep the heart in rhythm, and the rate 65 to 90 (better than 160 when in A Fib 44 hours). Only drawback is that I can be very forgetful about routine tasks such as remembering to carry glass of water to the table.

This medication has made me extremely tired. I also have forgotten to do simple daily routine tasks such as setting up the coffee pot at night. One short store trip, and I am exhausted! I will try something else.

My doctor started me on Metoprolol after cardiac ablation for Atrial Fibrillation. It actually made my heart rate worse. I was waking up at 2am-5am every single morning in tachycardia of 115-148 bpm. I stopped taking Metoprolol, and have been in normal sinus rhythm ever since. I am glad it works for most, it just did not work for me. Atrial Fibrillation and/or tachycardia is horrible, and they have got to come up with something new for us sufferers soon.

Keeps my heart rate down to 54-75 which is way better than 170 but I still get AF. I was in AF most of yesterday. I am on low dose, 50mg. Think I need to up it maybe.

I've been on Flecainide 12 years for A-fib but have recently been have more and more episodes. So my cardiologist also prescribed metoprolol (the smallest dose possible - 1/4 of a 25mg tablet twice daily - due to my being very sensitive to other beta blockers). My blood pressure dropped (wasn't high in the first place) and my heart rate dropped to the mid/low 40's. I was also very light-headed, had low energy, some shortness of breath and sometimes nausea. Discontinued (by doctor) after one week.
