Metoprolol is a medication that belongs to a class of drugs known as beta-blockers. It is commonly prescribed by doctors to treat a range of cardiovascular conditions, including:
- High blood pressure (hypertension): Metoprolol is effective in reducing blood pressure and preventing complications of high blood pressure, such as stroke and heart attacks.
- Angina: Metoprolol is used to treat chest pain (angina) by reducing the workload on the heart and improving blood flow.
- Arrhythmia: Metoprolol is effective in treating certain types of irregular heartbeat (arrhythmia) by slowing down the heart rate and reducing the workload on the heart.
- Heart attack: Metoprolol is used to prevent future heart attacks and to help reduce the risk of death in people who have had a heart attack.
- Heart failure: Metoprolol is prescribed to improve the symptoms and survival rate of people with heart failure, a condition in which the heart becomes weak and cannot pump blood effectively.
Overall, Metoprolol is a versatile medication that is widely used to treat various heart-related conditions. It works by blocking the effects of the hormone adrenaline on the heart, which reduces the heart rate and blood pressure, and helps to prevent or manage cardiovascular events.

Here are some general guidelines for taking Metoprolol:

Metoprolol Interactions
Metoprolol can interact with other medications, supplements, and certain foods. Some of the most common drug interactions with Metoprolol include:
- Calcium channel blockers: Combining Metoprolol with calcium channel blockers can increase the risk of side effects such as low blood pressure, slow heart rate, and dizziness.
- Antidepressants: Certain antidepressants, such as fluoxetine and paroxetine, can increase the concentration of Metoprolol in the body, increasing the risk of side effects.
- NSAIDs: Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and aspirin, can reduce the effectiveness of Metoprolol and may increase the risk of side effects.
- CYP2D6 inhibitors: Some medications, such as fluoxetine and quinidine, can inhibit the CYP2D6 enzyme, which is responsible for metabolizing Metoprolol, leading to higher levels of the drug in the body.
- Certain supplements: Supplements that lower blood pressure or affect heart rate, such as potassium supplements and fish oil, may interact with Metoprolol.
It’s important to talk to your healthcare provider about all medications, supplements, and foods you are taking before starting Metoprolol. Your healthcare provider may need to adjust your dose or monitor you more closely for side effects.
