S Metoprolol
About S Metoprolol
S Metoprolol is a prescription medicine containing the S-enantiomer (active form) of metoprolol, called S-metoprolol. It is primarily used to manage high blood pressure and prevent chest pain caused by angina. Doctors also prescribe it to support heart health following a heart attack and to manage chronic heart failure. By controlling the heart's workload, it helps reduce the risk of future cardiovascular complications such as stroke and heart attack.
To get the most benefit, you should take S Metoprolol consistently at the same time every day. You can take this oral tablet either with food or on an empty stomach, but it is best to stick to the same routine daily. Combining this medicine with a low-sodium diet and regular physical activity can greatly improve your long-term cardiovascular health.
While taking S Metoprolol, you may experience mild effects like feeling tired, dizzy, or having cold hands and feet. These are generally temporary, but you must contact your doctor immediately if you notice serious issues such as an unusually slow heartbeat or severe breathing difficulties.
Do not take this medicine if you have certain conditions, such as severe asthma, a very slow heart rate, cardiogenic shock, second- or third-degree heart block without a pacemaker, sick sinus syndrome, or severe untreated heart failure. Before starting treatment, tell your doctor if you have diabetes, thyroid problems, liver disease, or kidney disease so that appropriate monitoring can be arranged.
Additionally, certain substances like alcohol can increase drowsiness, and smoking may reduce how well this medicine works. If you are pregnant, breastfeeding, or an elderly individual, consult your doctor to ensure this medication is safe for your specific situation.

If treatment needs to be stopped, your doctor will gradually reduce the dose over several days to weeks to allow your body to adjust safely.
- Monitor Blood Sugar if You Have Diabetes: S Metoprolol may mask common warning signs of low blood sugar, such as a rapid heartbeat. Check your blood glucose regularly if you have diabetes.
- Inform Healthcare Providers: Tell your doctor, dentist, surgeon, or anaesthesiologist that you are taking S Metoprolol before any medical, surgical, or dental procedure.
- Check Your Pulse Regularly: Monitor your pulse as advised by your doctor and seek medical advice if it becomes significantly slower than recommended.
- Use Caution While Driving: Avoid driving or operating machinery until you know how S Metoprolol affects you, as it may cause dizziness or drowsiness.
- Check Before Taking Other Medicines: Consult your doctor or pharmacist before using over-the-counter medicines, especially cold or allergy remedies, as some decongestants may increase blood pressure or interfere with your treatment.
Drug Interactions
Drug-Drug Interactions
Some medicines may affect how S Metoprolol works or increase the risk of side effects. Tell your doctor about all the medicines you are taking, including:
- Calcium channel blockers (such as diltiazem or verapamil): May cause a dangerously slow heart rate, heart block, or low blood pressure.
- Certain antidepressants (such as fluoxetine or paroxetine): May increase the levels of S Metoprolol in your body, raising the risk of side effects.
- Digoxin: May further slow the heart rate and increase the risk of heart rhythm problems.
- Clonidine: Stopping clonidine while continuing S Metoprolol may cause a dangerous rise in blood pressure. Always follow your doctor's instructions when stopping either medicine.
- Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen: May reduce the blood-pressure-lowering effect of S Metoprolol.
- Other blood pressure medicines or antiarrhythmic medicines: May further lower blood pressure or slow the heart rate, requiring careful monitoring.
- Insulin and oral antidiabetic medicines: S Metoprolol may mask warning signs of low blood sugar, such as a rapid heartbeat, making hypoglycaemia more difficult to recognise. Monitor your blood glucose as advised by your doctor.
- Monoamine oxidase inhibitors (MAO inhibitors): These medicines may enhance the blood-pressure-lowering effects of S Metoprolol, increasing the risk of dizziness, fainting, or low blood pressure. Your doctor may recommend closer monitoring.
Drug-Food Interactions
Certain foods and drinks may affect how S Metoprolol works or increase the risk of side effects.
- Alcohol: May increase drowsiness and cause a sudden, unsafe drop in blood pressure.
Drug-Disease Interactions
Certain medical conditions may affect how S Metoprolol works or increase the risk of side effects. Inform your doctor if you have any of the following conditions before starting treatment.
- Asthma or COPD: May cause breathing difficulties or airway narrowing.
- Diabetes: May hide the symptoms of low blood sugar (hypoglycemia), such as a racing heart.
- Severe liver damage: May cause the medication to build up in your body, requiring lower doses.
- Severe kidney disease: Dose adjustment is generally not required, but people with significant kidney disease should be monitored by their doctor, particularly if they have other heart or kidney conditions.

- Adopt a low-sodium diet: Reducing salt intake helps lower your blood pressure naturally, supporting the action of the medication.
- Track your pulse: Check your pulse rate regularly at home. Talk to your doctor if your resting pulse rate falls below the range they recommend.
- Limit caffeine: Avoid excessive consumption of coffee, energy drinks, or tea, as caffeine can counteract the heart-rate-lowering effects of your medication.

- Do not stop taking S Metoprolol suddenly as it can cause your blood pressure to rise suddenly, thereby increasing the risk of heart attack and stroke.
Patients Concern
Disease/Condition Glossary
Hypertension: High blood pressure is a chronic condition when the blood pressure and the heart's workload is too high. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Raised blood pressure can cause chest pain (angina) and heart attack (when blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. High blood pressure can be diagnosed with the help of a blood pressure monitor or sphygmomanometer. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg and, diastolic pressure is 90 mm of Hg. Ideal blood pressure should be between 90/60 mm of Hg and 120/80 mm of Hg.
