Propranolol: functions, dosage, side effects, how to use

What is the drug propranolol?

What is propranolol for?

Propranolol is a beta-blocker drug with a function to treat high blood pressure, irregular heartbeats, shaking (tremors), and other conditions. This drug is used after a heart attack to increase the chance of survival. Propranolol is also used to prevent migraines and chest pain (angina). Lowering blood pressure helps prevent strokes, heart attacks, and kidney problems. Preventing chest pain can help improve your ability to perform activities.

This medication works by blocking the action of certain natural chemicals in your body (such as epinephrine) that affect the heart and blood vessels. This effect reduces heart rate, blood pressure, and strain on the heart muscles.

OTHER USES: This section lists uses for this drug that are not listed on approved labels, but may be prescribed by your healthcare professional. Use this medication for the conditions listed below only if it has been prescribed by your doctor and health care professional.

How is propranolol used?

Take this medication only by mouth, generally 2 - 4 times a day or as prescribed by your doctor. Take this medicine before meals (and at bedtime, if you schedule 4 times a day). Measure out liquid medicine with a spoon or the special medicine tool provided, if any. If not available, ask your pharmacist for a measuring spoon. Don't use a household spoon to avoid giving the wrong dose.

The dosage is always given based on your health condition and how you respond to therapy.

Take this medicine regularly to get optimal benefits. To help you remember, take this medication at the same time each day. It is important to continue taking this drug even if you feel better. Do not stop using this medication before consulting a doctor.

Propranolol is used to help prevent chest pain or migraines. This medicine should not be used to treat chest pain or migraines at the time of an attack. Use other medications (such as nitroglycerin tablets placed under the tongue for chest pain, sumatripan for migraines) to relieve seizures, as directed by your doctor. Consult your doctor or pharmacist for more information.

For treatment of high blood pressure, it may take 1 to 2 weeks before you feel the benefits of this drug.

Tell your doctor if your condition worsens (for example, your regular blood pressure reading goes up, your chest pain and migraines appear more frequently).
