What Are the 4 Major Harms of Taking Metoprolol?

The product name of Betaloc should be Metoprolol Tartrate Tablets. If abused without following medical advice, it may cause adverse effects such as gastrointestinal discomfort, slowed heart rate, lowered blood pressure, bronchospasm, and blood glucose fluctuations. Detailed explanations are as follows:

1. Gastrointestinal Discomfort: Prolonged use of the medication may irritate the gastrointestinal mucosa and affect normal intestinal function, leading to adverse effects such as nausea, vomiting, abdominal pain, and indigestion.

2. Slowed Heart Rate: Long-term misuse of the medication may potentially cause circulatory system dysfunction, resulting in bradycardia (slow heart rate) and cold extremities. Normally, Metoprolol Tartrate Tablets help return a rapid heart rate to the normal range. However, if the dosage is too high or the patient is particularly sensitive to the medication, excessive slowing of the heart rate may occur.

3. Lowered Blood Pressure: This medication reduces myocardial contractility and cardiac output, which may lead to decreased blood pressure. The risk of hypotension is especially increased during initial dose adjustment or when used in combination with other antihypertensive medications. When blood pressure drops suddenly, patients may experience symptoms such as dizziness, visual disturbances (e.g., darkening vision), and fatigue.

4. Bronchospasm: Metoprolol Tartrate Tablets may induce or worsen bronchospasm by blocking β₂-adrenergic receptors on bronchial smooth muscle, causing bronchoconstriction. Patients with a history of severe bronchial asthma should use Metoprolol Tartrate Tablets cautiously and under close observation.

5. Blood Glucose Fluctuations: Metoprolol Tartrate Tablets may inhibit β-receptors in the pancreas, potentially reducing glucose tolerance and causing blood glucose fluctuations.

Therefore, when taking Metoprolol Tartrate Tablets, it is essential to strictly follow medical instructions, monitor bodily reactions closely, and seek immediate medical attention if any discomfort occurs. Inform your doctor about your medication use promptly.
