What is Metoprolol (Pill Imprint 564)?
Metoprolol is a beta-blocker, which works by blocking the effects of adrenaline (epinephrine) on the beta receptors of the heart. By doing so, it slows down the heart rate, reduces the force of the heart’s contractions, and helps lower blood pressure. It is primarily used for:
- Managing high blood pressure (Hypertension)
- Preventing and treating angina (chest pain)
- Reducing the risk of heart attack
- Managing heart failure and abnormal heart rhythms (like atrial fibrillation)
Additionally, Metoprolol has several off-label uses such as migraine prevention, and it can help treat benign essential tremors.

Uses of Metoprolol 25 mg (Imprint 564)
Metoprolol, with the imprint “564”, is most commonly prescribed for:
- High blood pressure (Hypertension): Reducing blood pressure helps prevent strokes, heart attacks, and kidney problems.
- Angina (Chest pain): Metoprolol helps to relieve chest pain caused by reduced blood flow to the heart.
- Heart failure: It is used to help improve symptoms in patients with heart failure by reducing the heart’s workload.
- Arrhythmias: Metoprolol helps regulate heart rhythm disorders like atrial fibrillation.
- Post-heart attack care: It can help in post-myocardial infarction treatment to improve recovery and prevent further complications.
It is important to note that Metoprolol 25 mg is just one of the several available doses, with others like 50 mg, 100 mg, and 200 mg also prescribed depending on the condition being treated.
How Does Metoprolol Work?
Metoprolol works by blocking beta-adrenergic receptors in the heart, specifically the beta-1 receptors. This results in:
- Slower heart rate: This reduces the oxygen demand of the heart and helps prevent heart attacks and reduce chest pain.
- Lower blood pressure: This helps reduce the risk of stroke, heart disease, and kidney damage.
- Reduced stress on the heart: It prevents the heart from overworking, especially in patients with heart failure.
Dosage and Administration
The recommended dose for Metoprolol 25 mg depends on the specific condition being treated. However, as a guideline:
- For High Blood Pressure (Hypertension): The initial dose is typically 25 mg to 50 mg once a day, which can be increased based on individual response.
- For Angina: 25 mg to 100 mg once a day, depending on how well the patient tolerates the medication.
- For Heart Failure or Post-Heart Attack Treatment: The dose can be gradually increased, with close monitoring for side effects.
Metoprolol is usually taken orally with or without food, and it is important to follow your healthcare provider’s instructions regarding timing and dosage adjustments.
Potential Side Effects
As with any medication, Metoprolol 25 mg can have side effects, some of which may be more common than others. Potential side effects include:
- Fatigue or tiredness
- Dizziness or lightheadedness
- Slow heart rate (bradycardia)
- Shortness of breath or wheezing
- Cold hands and feet
- Low blood pressure (hypotension)
- Nausea and stomach upset
- Sleep disturbances or vivid dreams
In some rare cases, more serious side effects can occur, such as severe allergic reactions, liver problems, and heart block. If any severe symptoms arise, immediate medical attention is needed.
Who Should Avoid Metoprolol?
Metoprolol should not be used by certain individuals, including:
- Those with a history of severe asthma or other lung diseases (because Metoprolol can worsen bronchospasm).
- Individuals with bradycardia (extremely low heart rate) or heart block.
- Those with severe liver problems.
- Individuals with hypotension (low blood pressure) should also avoid Metoprolol unless prescribed by a doctor.
Always consult with your healthcare provider before starting any new medication, especially if you have a history of other medical conditions or are taking other medications.
