Medicine information
Uses & overview
Propranolol SR 40 mg is a sustained-release formulation of propranolol, a beta-blocker used under medical supervision for certain cardiovascular conditions. It works by blocking the effects of adrenaline on beta receptors, helping slow the heartbeat and reduce the workload on the heart. Depending on the patient’s condition and the prescribing doctor’s assessment, propranolol may be used for conditions such as high blood pressure, angina, selected heart rhythm disorders, or prevention of migraine. It may also be prescribed in some situations to help control physical symptoms such as a rapid heartbeat or trembling. The SR, or sustained-release, formulation releases the medicine gradually over time. Its dosing schedule may differ from that of immediate-release propranolol tablets, so the two formulations should not be substituted without professional advice. The appropriate dose and duration depend on the condition being treated, the patient’s medical history, heart rate, blood pressure, and response to treatment. Possible side effects include tiredness, dizziness, nausea, cold hands or feet, and a slower heartbeat. Propranolol may not be suitable for people with asthma, certain heart conduction problems, a very slow heart rate, or low blood pressure. People with diabetes should discuss its use with their doctor because beta-blockers can mask some warning signs of low blood sugar. Tell your healthcare professional about all medicines you take and any kidney or liver conditions.
How to use
Follow your prescription: Take Propranolol SR 40 mg exactly as prescribed. Your dose and schedule depend on your diagnosis and individual response. Check the formulation: Confirm that your medicine is the sustained-release (SR) product. Do not replace it with immediate-release propranolol unless your doctor or pharmacist approves the change. Take it consistently: Follow the prescribed timing each day and read the product leaflet for instructions about taking it with or without food. Swallow the tablet as directed: Do not crush or chew a sustained-release tablet. Split it only if the specific product instructions or your pharmacist confirm that doing so is appropriate. Handle missed doses carefully: Follow the patient leaflet or ask your pharmacist what to do if you miss a dose. Do not take a double dose. Monitor your response: Your doctor may check your blood pressure and heart rate, especially when starting treatment or adjusting your dose. Discuss other medicines: Inform your doctor about prescription medicines, over-the-counter products, and supplements that may affect heart rate or blood pressure. Mention existing conditions: Tell your doctor if you have asthma, diabetes, a slow heartbeat, low blood pressure, or kidney or liver disease. Use caution with daily activities: If you experience dizziness, tiredness, or blurred vision, avoid driving or operating machinery until you feel well. Do not stop suddenly: Consult your doctor before discontinuing Propranolol SR 40 mg, as abrupt withdrawal may worsen certain heart-related conditions.
