Description
Description
Merol 100mg is a cardioselective beta-blocker manufactured by ATCO Laboratories, formulated with Metoprolol. It works by blocking the effects of adrenaline on the heart, which slows the heart rate, reduces blood pressure, and eases the overall workload on the cardiovascular system. This makes it a widely prescribed option for managing hypertension, angina, and certain heart rhythm conditions.
Ingredients
Each tablet of Merol contains:
- Metoprolol – 100mg (a cardioselective beta-blocker)
Dosage Form
Merol 100mg is available as oral tablets, packed 30 tablets per strip/box.
Uses
Merol 100mg is commonly prescribed for:
- Management of essential hypertension (high blood pressure)
- Angina pectoris (chest pain due to reduced blood flow to the heart)
- Certain types of abnormal heart rhythms (arrhythmias)
- Long-term management after a heart attack, to help protect the heart
- Supporting treatment of heart failure, as part of a broader treatment plan under medical supervision
How to Use
Merol should be taken exactly as directed by a registered physician, typically once or twice daily, at the same times each day, with or without food. Swallow the tablet whole with a glass of water — do not crush or chew it. Your doctor will determine the right dose based on your condition and may adjust it gradually over time. Never stop taking Merol suddenly, as abrupt discontinuation can worsen chest pain or trigger heart-related complications; any dose changes should be made gradually under medical guidance.
Side Effects
Common side effects that may occur with Merol include:
- Fatigue or tiredness
- Dizziness
- Slow heart rate (bradycardia)
- Cold hands or feet
- Low blood pressure (hypotension)
- Headache
- Nausea
Seek immediate medical attention if you experience severe dizziness, fainting, difficulty breathing, or a very slow or irregular heartbeat.
Pregnancy & Breastfeeding
Merol should only be used during pregnancy if a doctor determines the benefits outweigh the potential risks, as beta-blockers may affect fetal growth and heart rate, particularly if used in later stages of pregnancy. Metoprolol passes into breast milk in small amounts, so breastfeeding mothers should consult their physician before use. Pregnant or breastfeeding women should never self-medicate with this drug.
Storage Instructions
Store Merol tablets below 30°C in a cool, dry place, away from direct sunlight and moisture. Keep the tablets in their original packaging until use, and store them out of reach of children.
FAQs
Q: Can Merol be stopped suddenly if I feel better?

Q: How long does it take for Merol to start working?
A: Blood pressure and heart rate effects are usually noticeable within a few hours, though full benefits may take a few weeks of consistent use.
Q: Can Merol be taken alongside other heart medicines?
A: Yes, but only under medical supervision, as combining it with certain other drugs may increase the risk of very low blood pressure or heart rate.
