Does Accidental Double Dosage Of Metoprolol Cause Adverse Effects?

Posted on Tue, 24 Apr 2018

Question: I'm a 50 year old male. I'm healthy but I take 1ea 25mg Metoprolol ER Succinate every morning for what my primary care, cardiologist, and ep doctors describe as "safe" palpitations related to mitral valve prolapse. This morning, I may have only taken 1 tablet but it's possible that I had 2. Should I worry about any issues or just go about my day normally and take 1 tomorrow morning out of a daily pill counter box and not the bottle (so dumb today!)?

Detailed Answer:
Hello!

Welcome and thank you for asking on HCM!

Regarding your concern, I would explain that a double dose of Metoprolol, may lead to lower blood pressure and heart rate values.

This may lead to dizziness and light-headedness or increased fatigue. In such case having some rest and taking plenty of fluids would help.

Anyway, this is a really low dose of Metoprolol (50mg), and I don't think that any serious adverse effects will occur.

Tomorrow, you can continue to take your daily dose as always.

So, just relax and don't worry about it!

Kind regards,

Dr. Iliri
