Do not change or skip your dose based only on one pulse reading unless a healthcare professional has specifically instructed you to do so.
When a Slow Heart Rate Needs Attention
A very slow pulse accompanied by fainting, severe weakness, difficulty breathing, chest discomfort, or confusion should be evaluated promptly.
Your clinician may review your dose and other medications that can also slow the heart.
Medicines That May Add to the Heart-Rate-Lowering Effect
Other drugs that affect heart rate or electrical conduction can sometimes amplify metoprolol’s effects.
This is why your doctor and pharmacist should know about every prescription medication, over-the-counter product, and supplement you take.
A slower pulse can be an intended effect of metoprolol, but slow heart rate plus fainting, severe weakness, or breathing difficulty is a different situation and should not simply be ignored.
4. Low Blood Pressure
Metoprolol is often prescribed specifically because it lowers blood pressure.
