Metoprolol: Are you experiencing side effects?

Thanks, everyone, for sharing your experiences with Metoprolol. I also posted a question about increasing dizziness about 10 days ago. After reading so many helpful posts on this site, I’m wondering if my dizziness is a side effect of Metoprolol or hocm or both? Some have said that their dizziness w/ Metoprolol eventually goes away…I wonder how long until that occurred? I’ve been on the drug for almost 5 mos now - seems long enough to adjust to the med. I’m scheduled for a consult at Keck USC in early Oct & am hoping to receive good advice re meds or surgery.

@luckyhowreyou Welcome to Connect! You are going through an unsettled time right now - meds that you could not take and a scheduled ablation that you are very nervous about ((HUG)). It is not uncommon to experience side effects from Metoprolol - if you scroll to near the bottom of this article, you can read all about the side effects. (Sometimes I do wonder how people choose to take a drug knowing the seemingly endless list of side effects.) https://www.mayoclinic.org/drugs-supplements/metoprolol-oral-route/description/drg-20071141 I take 50mg of Metoprolol each morning.

I hope others chime in about their ablation experience, I had a septal myectomy, ablation would have been less effective in my case.

Where are you receiving care?

@walkinggirl. My doctors are at Northwell - L I J
Ablation pvc is scheduled for 9/28. More nervous about meds as I have a stomach that cannot tolerate any, but my dr scared me and said I could die!

@luckyhowreyou I was diagnosed 4 yrs ago, but obviously it got worse recently as shownona monitor and echo. My stomach issues have me throwing up occasionally, but the dr said that. Wouldn’t. Cause. The recent decline. Suffer. From. Depression. As. A. Result where I have never suffered this. Before. Where are the. Golden years?

@danafitz I agree that 5 months is probably enough time to adjust to Metoprolol. On a different post, @bbisno asked about the side effects and I posted this article in the reply.

I did not have dizziness from the Metoprolol, 50 mg each morning ever since a septal myectomy 4 years ago. I did develop an electrical problem causing arrythmia after the surgery, I experienced dizziness and giddiness and 2 syncope. I acquired Buddy, my ICD, to pace my heart. Worked wonderfully.

Have you been diagnosed with HCM?

@walkinggirl
Yes - obstructive hcm, diagnosed in March 2026. I had a little dizziness when I first went on 25 mg of Metoprolol, then it subsided after a few days. Dizziness again when the dose was increased to 50 mg, and then it subsided. But it seems to me now that the dizziness is increasing and is much worse than before. Especially during and after exercise, to the point where I feel unable to function, sometimes with visual disturbances. Is it from the hocm? Metoprolol? Who knows?

@danafitz
I had a bout of vertigo when lying down last week while at Chautauqua Ny - gone when returned to Chicago - cause? Been on Metropolol for a few years - have to deal with constant fatigue - sleep well

@luckyhowreyou @bbisno @danafitz I wish to add one more thing to this helpful discussion on Metoprolol side effects - dizziness - vertigo - fatigue and the rest of it. Hydration. Are each of you well hydrated? I find that if I am not well hydrated, I get that dizzy-not-feel-like-myself. I am always asked by my cardiologist and PCP how much I drink each day, both recommend 2 liters/quarts each day for me. I have a 32 oz refillable water bottle that I fill twice a day. Both HCM and Metoprolol have a negative effect on kidneys; water keeps them well flushed. Hearts and related matters function better when hydrated. We get more liquid from food (think juicy apples and oranges) that adds to the 60+ ounces. Ask your doctors how much water you need to drink every day.
