Product introduction
Metolar XR 50 is an extended-release capsule containing metoprolol succinate, a heart-selective beta blocker used mainly for long-term control of blood pressure and certain heart conditions. Because it is an extended-release formulation, it releases the medicine gradually through the day, allowing once-daily dosing. It is also prescribed at times to reduce the frequency of migraine attacks and to lower the strain on the heart in people with angina or irregular heart rhythms. This is a long-term maintenance medicine rather than one used for sudden relief.

Uses of Metolar XR 50 Capsule
- Hypertension (high blood pressure)
- Angina (chest pain)
- Arrhythmia (irregular heartbeat)
- Migraine prevention
- Prevention of heart attack and stroke
Benefits of Metolar XR 50 Capsule
Taken consistently, it helps keep blood pressure within a healthier range and reduces the heart's workload, which can ease chest pain in people with angina and help stabilise irregular heartbeats. In people prone to migraines, regular use may reduce how often attacks occur, and by controlling blood pressure and heart strain over time it also lowers the long-term risk of heart attack and stroke.

- Dizziness
- Tiredness
- Slow heart rate

How to use Metolar XR 50 Capsule
Take the capsule once daily at the same time each day, generally in the morning, with or without food, exactly as prescribed by the doctor. It should be swallowed whole and not broken, crushed, or chewed, since doing so can disrupt the extended-release action. The dose should not be stopped suddenly without medical advice, as abrupt discontinuation can cause a rebound rise in heart rate or blood pressure.
How Metolar XR 50 Capsule works
Metoprolol succinate is a cardioselective beta blocker that acts mainly on beta-1 receptors in the heart. It slows the heart rate and reduces the force of each heartbeat, which lowers blood pressure and eases the heart's oxygen demand. In migraine prevention, it is thought to work by stabilising blood vessel tone and reducing the nerve activity associated with triggering attacks.

Safety advice
Alcohol can add to the blood-pressure-lowering effect of this medicine, so it should be consumed cautiously, if at all.
Safety in pregnancy is not firmly established, so it should only be used if a doctor decides the benefit clearly outweighs the potential risk.
It is not expected to pass into breast milk in significant amounts, so it is generally considered acceptable while breastfeeding under medical supervision.
It may cause dizziness, tiredness, or reduced alertness, so driving or operating machinery should be avoided until you know how it affects you.
Generally does not require a dose adjustment in people with kidney impairment, though monitoring may still be advised.
People with liver impairment may need a lower dose, so it should be used carefully and only under medical guidance.
Quick tips
- Take the capsule at the same time daily to maintain a steady level of medicine in the body.
- Swallow the capsule whole; do not crush or chew it, as this affects its slow-release action.
- Never stop taking it abruptly without consulting your doctor, even if you feel well.
- Monitor your blood pressure and pulse periodically as advised, and report unusually slow heartbeats or dizziness.
- Limit alcohol intake, as it can add to the blood-pressure-lowering effect and increase the risk of dizziness.

Its blood-pressure-lowering effect can begin within a few hours of the first dose, but the fuller benefit usually builds up over about a week of regular use.

Its effect on sleep varies between individuals; some people may notice mild changes such as vivid dreams or disturbed sleep, while others notice no difference.
