What is metoprolol?


Metoprolol is a beta-blocker which alters the heart as well as circulation (blood flows through veins and arteries).

This medication is used in the treatment of angina (chest pain) and hypertension (high blood pressure).

Metoprolol can also be utilized to reduce the chance of dying or having to be hospitalized due to heart failure. Metoprolol injection is administered during the first stage after a heart attack in order to lower the risk of dying.


Metoprolol should not be used in the event of a severe heart issue (heart block or sick sinus syndrome, low heart beat) or have severe circulation issues and heart failure severe or have a background of heartbeats that are slow which led to fainting.


Before taking this medication, you must consult your physician

It is not recommended to use this medication if you have an allergy to metoprolol, or any other beta-blockers (atenolol or carvedilol, labetalol, and nebivolol), nadolol, propranolol, sotalol, or other) or are suffering from:

  • an issue with the heart that is serious, like heart block or sick sinus syndrome or a slow rate of heartbeat;
  • chronic circulation problems;
  • severe heart failure of the heart (that forced you to be admitted to the hospital) •
  • A history of heartbeats that are slow and may have led to your fainting.

To ensure that this medication is suitable for you, inform your doctor if:

  • asthma, chronic obstructive lung disease (COPD) sleep apnea, or other breathing disorders.
  • diabetes (taking metoprolol can make it difficult to detect the condition of having low glucose);
  • liver disease;
  • congestive heart failure;
  • issues that affect circulatory issues (such as Raynaud’s Syndrome);
  • a thyroid disorder; or
  • Pheochromocytoma (a tumor that affects the adrenal gland).

Don’t give the medication to any child without medical guidance.

Consult your doctor if are expecting or planning to be pregnant. It’s not clear if metoprolol can harm an unborn baby. But being pregnant with high blood pressure could lead to complications, such as eclampsia or diabetes (dangerously hypertension that could cause medical issues in both the mother and the baby). The benefits of treating hypertension could outweigh any risk for the baby.
