What happens if you miss a dose of metoprolol?
If you forget a dose of metoprolol, what happens next usually depends on (1) how much time has passed and (2) whether you’re taking metoprolol tartrate or metoprolol succinate.
In general, missing one dose can let your blood pressure or heart rate rise back toward your pre-treatment levels. For some people, that can feel like increased palpitations, a “racing” heartbeat, dizziness, or shortness of breath—especially if metoprolol is helping control symptoms like angina (chest pain) or certain abnormal heart rhythms.
When should you take the missed dose?
A common safe approach for missed doses of metoprolol is:
- If you remember soon after the scheduled dose, take it.
- If it’s close to the time of your next dose, skip the missed dose and take your next dose on schedule.
- Do not take two doses at once to “make up” the missed one.
Because the exact instruction can vary by formulation and prescription directions, follow the instructions on your specific prescription label.
What if you miss multiple doses?
Forgetting more than one dose can lead to a more noticeable loss of heart-rate and blood-pressure control. That can increase the risk of symptoms returning—such as:
- chest pain (if you take metoprolol for angina)
- worse heart failure symptoms (if you take it for heart failure)
- increased irregular heart activity for some people
The risk level also depends on why you take metoprolol (hypertension, angina, heart failure, post-heart-attack, or rhythm control).
Can missing metoprolol be dangerous?
It can be, particularly if:
- you take it for angina, heart failure, or rhythm problems
- you stop suddenly after taking it regularly (beta-blockers are usually tapered if discontinuing long-term therapy)
- you have underlying heart disease and miss several doses
If you miss doses and then start feeling chest pain, fainting, severe shortness of breath, or new/worsening weakness, get urgent medical help.
What happens if you stop metoprolol suddenly (not just one missed dose)?
Suddenly stopping after regular use can cause rebound effects. People may experience worsening angina, increased heart rate and blood pressure, and in some cases more serious cardiovascular symptoms. This is one reason clinicians often recommend tapering rather than abrupt discontinuation—especially for people taking metoprolol for heart disease conditions.
What should you do right now?
If you missed a single dose:
- Take it only if you’re still within the “missed dose” window described on your label or prescriber instructions.
- Otherwise, skip and resume your next scheduled dose.
- Don’t double up.
If you tell me your metoprolol type (tartrate vs succinate), your dose, and how long ago you missed it, I can help you apply the timing rule more specifically.
