Provanol SR 40 Tablet

Provanol SR 40 Tablet is a sustained-release tablet of propranolol, with 40 mg in each tablet. Propranolol is a beta-blocker used for heart and blood pressure problems, and it is also prescribed for some migraine, tremor, and anxiety-related symptoms. The sustained-release design of Provanol SR 40 Tablet helps release the medicine gradually over time rather than all at once. It should be used only when a clinician has decided this 40 mg strength is appropriate.

How it works: Propranolol blocks beta receptors, which slows the heart rate and reduces how hard the heart has to work. In the Provanol SR 40 Tablet form, the medicine is released gradually from the tablet so its effect lasts longer through the day.

Provanol SR 40 Tablet is a mid-strength sustained-release option, sitting above Provanol 10 Tablet and Provanol 20 Tablet and below Provanol SR 80 Tablet. Because it releases medicine slowly, it may be chosen when a doctor wants steadier 24-hour coverage and a smoother effect than an immediate-release tablet. It is not meant for quick symptom relief or for people who need a lower starting dose.

• High blood pressure
• Fast or irregular heartbeat
• Chest pain related to the heart
• Migraine prevention
• Essential tremor
• Physical symptoms of anxiety

• Swallow Provanol SR 40 Tablet whole with water; do not crush, chew, or split it because it is a sustained-release tablet.
• Take it at the same time each day to keep a steady level of medicine in your body.
• You may take it with or without food, but taking it with food can help if it upsets your stomach.
• If you miss a dose, take it when you remember unless it is close to the next dose; do not double up.
• Do not stop taking Provanol SR 40 Tablet suddenly unless your doctor tells you to, because that can worsen heart symptoms or raise blood pressure.
• If your doctor changed you from a lower-strength propranolol tablet, follow the new schedule exactly because this 40 mg SR tablet lasts longer.

Each Provanol SR 40 Tablet provides 40 mg of propranolol in a sustained-release tablet. How often it is taken depends on the condition being treated, but extended-release propranolol is commonly prescribed once daily; some patients may need a different schedule based on their doctor’s plan. The maximum daily dose varies widely by indication and response, so your doctor should set the dose and any increase carefully, especially with this stronger sustained-release form.

Do not change your dose or stop the medicine without speaking to your doctor.
