Active Ingredient: Metoprolol Tartrate (50mg).
What it does: It is a selective beta-blocker ($\beta_1$-blocker) that blocks stress hormones like adrenaline, lowering your heart rate and reducing blood pressure.
Prescribed for: High blood pressure (hypertension), chest pain (angina pectoris), irregular heart rhythms (arrhythmias), recovery after a heart attack, and the prevention of migraine headaches.
Standard Regimen: The dose ranges widely based on the condition (from 50mg to 200mg daily) and is taken either as a single dose or divided into 2 separate doses throughout the day.
Important Rules: Take your tablet at the same time every day, preferably with or immediately following a meal to enhance absorption. Swallow the tablet whole with water.
Crucial Safety Rule: NEVER stop taking this medicine suddenly. Abruptly halting a beta-blocker can cause a severe spike in blood pressure, heart palpitations, or trigger a heart attack. Your doctor will taper your dose slowly over 1 to 2 weeks.
Diabetes Warning: This medicine can hide the standard symptoms of low blood sugar (hypoglycemia), such as a fast heart rate or tremors.
Dizziness, lightheadedness, or feeling unusually tired or fatigued.
Slow heart rate (bradycardia), low blood pressure, and cold hands or feet.
Nausea, minor stomach upset, or mild shortness of breath.
