Feeling anxious before a speech, event or social engagement? Originally designed to treat heart conditions, propranolol is also a highly effective medication for treating the physical symptoms of social and performance anxiety.

Below, we’ve explained what propranolol is, how it works and how you can use it to manage most performance anxiety symptoms. We’ve also explained how propranolol differs from the other drugs used to treat anxiety, such as alprazolam (Xanax) and diazepam (Valium).

What is Propranolol?

Propranolol is a beta blocker -- a type of medication that works by blocking the beta receptors found in your body.

Developed in the 1960s, propranolol is one of the oldest and most widely used beta blockers in existence. There are millions of prescriptions for propranolol in the US alone, making it an incredibly popular medication.

Propranolol is available in a variety of forms, from an oral tablet to an injection. The majority of people who use propranolol on a regular basis are prescribed the oral version of the medication.

Like other beta blockers, propranolol was originally designed as a treatment for heart conditions, such as irregular heart rate or high blood pressure. Most people who are prescribed propranolol use it for this purpose.

In addition to treating certain heart conditions, propranolol also works as a treatment for some of the effects of anxiety. Today, it’s commonly prescribed off-label to treat performance anxiety and social anxiety.

How Does Propranolol Treat Performance Anxiety?

First off, it’s important to understand that propranolol technically isn’t an anti-anxiety medication like Xanax (alprazolam, a benzodiazepine) or Zoloft (sertraline, an SSRI).

These drugs work by targeting specific parts of your brain and central nervous system, causing you to feel relaxed and calm. Although the specifics are complicated, they essentially work by stopping you from feeling the physical and psychological effects of anxiety.

Medications like Xanax and Zoloft are usually prescribed to treat long-term, persistent anxiety disorders such as panic disorder and generalized anxiety disorder (GAD).

On the other hand, propranolol works by specifically targeting receptors in your body to block the action of stress hormones that cause the physical effects of anxiety. It’s prescribed off-label as a treatment for specific types of anxiety that occur in certain situations, such as social anxiety or performance anxiety.

Social anxiety usually occurs when you’re around other people. Many people feel anxiety about being judged by others or by doing or saying something embarrassing in a social environment.

Performance anxiety is a type of anxiety that can occur when you’re required to perform in front of others. It can strike when you need to perform in public, such as giving a speech, as well as in private, such as having an interview one on one with someone.

When you feel anxiety, such as before meeting a new person or performing in front of others, it can trigger certain physical symptoms. These include:

  • A dry mouth, taut throat and difficulty speaking

  • A faster pulse and rapid breathing

  • Nausea, discomfort and dizziness

  • Shakiness in your hands, jaw and lips

  • Sweating, especially from your hands  

These symptoms don’t just develop out of nowhere. Instead, they’re a physical reaction caused by the presence of specific stress hormones in your body, particularly the hormones adrenaline (epinephrine) and noradrenaline (norepinephrine).

When you feel nervous and stressed, such as before delivering a speech, your body ramps up its production of these stress hormones. These hormones work by attaching to beta receptors throughout your body.

Once these hormones attach to your beta receptors, they trigger the anxiety symptoms listed above, from shaky hands to sweating, nausea and a rapid heartbeat.

Propranolol works by blocking these receptors. With these receptors blocked, stress hormones like adrenaline don’t have their normal effects on your heart and other tissue. This means you’re less likely to experience physical symptoms like shaking, sweating or a rapid pulse.

Since propranolol only blocks beta receptors, it doesn’t actually stop the psychological effects of anxiety. You might still feel nervous before delivering a speech or meeting someone, but it’s less likely to result in any kind of physical reaction.

Interestingly, although propranolol doesn’t directly affect your brain, it can help to make you feel less nervous. Without the shaking, rapid heartbeat and sweating that usually happens when you feel anxious, it can become easier to relax, perform and stay focused.

Studies show that propranolol works best as a short-term treatment for specific types of anxiety, such as performance anxiety, social anxiety and specific phobias. Propranolol isn’t beneficial for treating other types of anxiety, such as generalized anxiety disorder.

How to Use Propranolol for Performance Anxiety

Propranolol is a prescription medication, meaning you’ll need to talk to your doctor before you can buy and use it.

Using propranolol to treat performance or social anxiety is a simple process. Many people prescribed propranolol off-label take 10mg to 80mg of propranolol approximately one hour before the event that’s likely to cause stress, depending on the severity of their anxiety.

However, only use the dosage recommended by your healthcare provider.

Propranolol has a half-life of three to six hours, meaning it can last a few hours with one dose. Using a lower dose of propranolol than is recommended by your healthcare provider can reduce the drug’s effects and provide shorter-acting relief from anxiety symptoms.

Like with other medications for anxiety, it can take time to work out the right dose of propranolol for you. Most doctors recommend starting with a low to moderate dose and adjusting your dose based on your results and side effects.

Propranolol vs. Benzodiazepines for Performance Anxiety

Benzodiazepines such as alprazolam (Xanax) and diazepam (Valium) are also commonly used to treat anxiety. Although they might seem similar, beta blockers such as propranolol differ from benzodiazepines in several ways:

  • Propranolol is not physically addictive. Although it’s possible to abuse propranolol and other beta blockers, these drugs aren’t physically addictive. Benzodiazepines such as Valium and Xanax, on the other hand, have a high risk of causing physical addiction.

  • Propranolol is designed for short-term, event-based anxiety. Benzodiazepines are normally prescribed for long-term, generalized anxiety, whereas propranolol works best as a treatment for short-term, event-based anxiety.

  • Propranolol primarily affects the body’s response to stress, not the brain. Benzodiazepines like Xanax® reduce anxiety by targeting parts of the brain and central nervous system. Propranolol primarily works by targeting the heart and other tissue with beta receptors.

In general, propranolol works best as a treatment for event-based anxiety, whereas drugs like benzodiazepines and SSRIs are normally used to treat recurrent, persistent anxiety disorders that aren’t triggered by specific events or settings.

Does Propranolol Have Side Effects?

Used responsibly at a normal dose, propranolol is a safe, effective treatment for performance and social anxiety. However, like other beta blockers, it can result in some side effects.
