Discovering the 10 Most Common Side Effects of MetoprololMetoprolol is a prescription medication called a beta blocker. It is commonly used to treat:
- High blood pressure
- Angina (chest pain)
- Heart failure (certain forms)
- Irregular heart rhythms
- To reduce the risk of future heart problems after a heart attack
Like all medications, metoprolol can cause side effects, although many people take it without significant problems.
10 Common Side Effects
- Fatigue or tiredness
- One of the most common side effects, especially when starting treatment or after a dose increase.
- Dizziness or lightheadedness
- May occur because metoprolol lowers blood pressure and slows the heart rate, particularly when standing up quickly.
- Slow heart rate (bradycardia)
- A slower pulse is expected to some degree, but an excessively slow heart rate should be evaluated.
- Cold hands and feet
- Reduced blood flow to the extremities can make them feel cold.
- Low blood pressure
- Symptoms may include dizziness, fainting, or blurred vision.
- Shortness of breath
- This is uncommon but may occur in some people, especially those with asthma or certain lung conditions.
- Digestive symptoms
- Nausea, diarrhea, constipation, or stomach discomfort can occur.
- Sleep disturbances
- Some people report insomnia, vivid dreams, or nightmares.
- Depressed mood
- Mood changes have been reported, although they are not common and the relationship is not always clear.
- Sexual side effects
- Some people experience decreased libido or erectile dysfunction.
Important precautions
- Do not stop taking metoprolol suddenly. Abruptly stopping it can lead to a rapid increase in heart rate or blood pressure and may increase the risk of chest pain or heart attack in some people. If it needs to be stopped, your healthcare provider will usually recommend tapering the dose.
- Take it exactly as prescribed and let your healthcare provider know about any new medications or supplements, as interactions are possible.
When to seek medical attention
Contact your healthcare provider promptly if you develop:
- Fainting or severe dizziness
- A very slow heart rate accompanied by symptoms
- Worsening shortness of breath or wheezing
- Swelling of the legs or sudden weight gain
- Chest pain
- Signs of an allergic reaction, such as swelling of the face, lips, or tongue, or difficulty breathing (seek emergency care)
The bottom line
Metoprolol is an effective medication that helps many people manage heart and blood pressure conditions. Most side effects are mild and often improve as the body adjusts to the medication, but any severe or persistent symptoms should be discussed with your healthcare provider.
If you’re taking metoprolol and have a specific symptom you’re concerned about, tell me your dose, how long you’ve been taking it, and the symptom you’re experiencing, and I can help you understand whether it could be related to the medication.
