10 Important Side Effects of Metoprolol That You Need to Know

New swelling should be evaluated in context. In someone with heart failure, increasing ankle swelling may indicate fluid retention or worsening disease rather than a simple medication side effect.
Can metoprolol affect blood sugar?

The more important concern for many people with diabetes is that beta blockers can reduce awareness of some warning symptoms of hypoglycemia.
Should I stop taking metoprolol if I feel dizzy?

Do not stop it abruptly. Contact your healthcare professional, especially if dizziness is persistent, severe, or associated with fainting or unusually low blood pressure.
Can metoprolol be taken long term?

Yes. Many people use metoprolol for years when it remains appropriate for their condition and is monitored properly.
What happens if I suddenly stop metoprolol?

Stopping suddenly may cause rebound increases in heart rate and blood pressure and can worsen angina or cardiovascular risk in susceptible individuals.
Can I exercise while taking metoprolol?

Many people can exercise while taking it, but heart-rate response will usually be lower. People with heart disease should follow individualized exercise recommendations.
Can I take metoprolol only when my blood pressure is high?

Do not convert a regularly prescribed medication into an “as needed” treatment unless your clinician specifically instructs you to do so.
What Should You Do if Side Effects Become Troublesome?

Keep track of:

When symptoms started
Whether they began after a dose change
Your blood pressure if you have been asked to monitor it
Your heart rate
Other new medications
Whether symptoms occur after standing, exercising, or eating

This information can help your clinician determine whether metoprolol is responsible and whether the dose or treatment plan needs adjustment.
Do Not Compare Your Dose With Someone Else’s

Metoprolol doses vary substantially depending on the condition being treated and the formulation prescribed.

A dose appropriate for one patient may be inappropriate for another.

Never increase, reduce, split, or discontinue your medication based on someone else’s prescription.
Final Thoughts

Metoprolol is an important cardiovascular medication that can lower blood pressure, reduce heart rate, control certain rhythm problems, relieve angina, and improve outcomes in selected patients with heart disease.

Most people do not experience every side effect listed above.
