Description
Description
Merol 25mg 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, lowers blood pressure, and reduces the overall workload on the cardiovascular system. This lowest strength is often used as an initial dose, for elderly patients, or for those who are more sensitive to beta-blocker therapy.
Ingredients
Each tablet of Merol contains:
- Metoprolol – 25mg (a cardioselective beta-blocker)
Dosage Form
Merol 25mg is available as oral tablets, packed 30 tablets per strip/box.
Uses
Merol 25mg 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, often as a starting dose that is gradually increased 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. This lower strength is frequently used at the start of treatment or in patients requiring careful, gradual dose adjustments, such as those with heart failure or elderly patients. 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.
