How does metoprolol work?
Metoprolol blocks beta receptors in the heart, slowing the heart rate and reducing blood pressure, which helps improve circulation and reduce strain on the heart.
What is metoprolol used to treat?
Metoprolol is commonly prescribed for:
- High blood pressure (hypertension)
- Angina (chest pain caused by reduced blood flow to the heart)
- Preventing heart attacks and improving recovery after a heart attack
- Managing irregular heart rhythms (arrhythmias)
- Preventing migraines (in some cases)
Who can take metoprolol?
Metoprolol is suitable for most adults with heart-related conditions, as prescribed by a doctor.
Who might not be able to take metoprolol?
Metoprolol may not be suitable if you:
- Have severe asthma or chronic obstructive pulmonary disease (COPD)
- Have low blood pressure (hypotension)
- Have a slow heart rate (bradycardia) or heart block
- Have circulatory problems (such as Raynaud’s disease)
Can I take metoprolol if I’m pregnant or breastfeeding?
Metoprolol isn’t usually recommended during pregnancy or breastfeeding, as it may affect the baby. Speak to your doctor about safer alternatives.
What if I miss a dose?
If you forget a dose, take it as soon as you remember. If it’s close to your next dose, skip the missed one—do not take two doses at once.
How effective is metoprolol?
Metoprolol is highly effective at lowering blood pressure, reducing angina symptoms, and preventing heart-related complications when taken consistently.
What should I do if I take too much?
Taking too much metoprolol can cause dangerously low blood pressure, slow heart rate, dizziness, or fainting. If you think you’ve taken too much, seek emergency medical help immediately.
What dose of metoprolol is usually taken?
- For high blood pressure: 50mg to 100mg once or twice daily
- For angina: 50mg to 100mg once or twice daily
- For heart attack prevention: 100mg twice daily
- For arrhythmias: 50mg to 100mg daily, as prescribed
Your doctor will determine the correct dose based on your condition.
