FAQs
Common questions about propranolol
Below you’ll find answers to a few commonly asked questions about propranolol.
Can propranolol be used for anxiety?
Possibly. Propranolol isn’t approved to treat anxiety. But doctors may choose to prescribe it off-label for this condition. With off-label use, doctors prescribe a drug for a purpose other than what it’s approved for.
You can learn more about using propranolol to treat symptoms of anxiety by talking with your doctor.
How does propranolol work? And how long does it take to start working?
Propranolol works by relaxing your blood vessels. This lowers your blood pressure. It also makes it easier for your heart to pump and slow your heart rate. As a result, your heart doesn’t have to work as hard to pump blood.
Propranolol will usually start to work within a few hours of taking it. But it can take a few days to weeks to see the full effects of the drug.
If you’d like to know more about how propranolol works, talk with your doctor or pharmacist.
Uses
Uses of propranolol
The Food and Drug Administration (FDA) approves prescription drugs such as propranolol for certain conditions. Approved uses for propranolol are described below.
Use for certain heart and blood pressure problems
Doctors may prescribe the following forms of propranolol for treating certain heart conditions:
- oral tablet
- oral liquid
- extended-release (ER) oral capsule*
- injection given by intravenous (IV) infusion into your vein over time
They’re used for this purpose in adults. The oral tablet, oral liquid, and ER oral capsule* are usually prescribed as a long-term treatment. The IV injection is for short-term treatment, usually in a hospital or emergency room.
Propranolol can help lower the risk of dying after a heart attack. It can also help relieve symptoms of the following heart conditions:
- angina (chest pain) due to coronary artery disease
- heart muscle disease
- heart rhythm problems, including atrial fibrillation (AFib)
Doctors may prescribe propranolol oral tablet, oral liquid, or ER oral capsule* for treating high blood pressure. They’re used for this purpose in adults. They’re usually prescribed as a long-term treatment.
With high blood pressure, you usually don’t have any symptoms. But having high blood pressure puts you at risk of having serious, sometimes fatal, problems. This includes heart attack and stroke. Lowering your blood pressure with propranolol can help prevent these life threatening problems.
Propranolol can be prescribed together with other medications to lower blood pressure.
* “Extended release” means the drug is slowly released into your body over a long period of time.
Use for a certain type of tumor
Doctors may prescribe propranolol oral tablet or oral liquid for treating symptoms of pheochromocytoma (a rare tumor of the adrenal gland). It’s used for this purpose in adults. It may be prescribed as a short-term or long-term treatment.
With pheochromocytoma, tumors in your adrenal glands cause them to produce increased levels of certain hormones. These hormones support blood pressure, heart rate, how you respond to stress, and more. When these hormones are elevated, you may experience symptoms, including:
- fast heart rate
- high blood pressure
- headaches
- sweating
For this use, propranolol is prescribed together with an alpha-blocker drug, such as prazosin.
Use for migraine
Doctors may prescribe propranolol oral tablet, oral liquid, or ER oral capsule* to help prevent migraine headache. They’re used for this purpose in adults. They’re usually prescribed as a long-term treatment.
With migraine headache, people get attacks of pain, throbbing, or pounding in the head. Symptoms usually affect one side of the head and can be severe. Propranolol can help lower how often migraine headaches occur and their severity. Propranolol won’t stop a migraine headache once it has started.
* “ER” means the drug is slowly released into your body over a long period of time.
Use for tremor
Doctors may prescribe propranolol oral tablet or oral liquid for treating essential tremor. They’re used for this purpose in adults. They’re usually prescribed as a long-term treatment.
With essential tremor, you have shakiness that usually affects the hands or arms. The tremor happens when using your hands or arms or when holding them out. It doesn’t occur when resting your hands or arms. It’s a form of tremor that’s genetic, so children inherit it from a parent.
