Propranolol for Anxiety: Uses, Side Effects & What to Expect
Propranolol — a beta-blocker (brand name Inderal) — is commonly used off-label, as needed, for performance or situational anxiety. It calms the physical symptoms — pounding heart, shaky hands, sweating — without sedating you or clouding your thinking. Taken about 30–60 minutes before a stressful event. It is not addictive.

What is propranolol?
Propranolol is a beta-blocker — a heart and blood-pressure medication. In psychiatry it’s used off-label because it blocks the effects of adrenaline on the body, quieting the physical “fight-or-flight” symptoms that make anxiety feel worse. It’s sold as Inderal and as a generic.
What is it used for in anxiety?
Propranolol is most useful for performance and situational anxiety — public speaking, presentations, auditions, interviews. It targets the physical symptoms (racing heart, trembling, sweating) rather than ongoing worry, so it’s typically used as needed rather than every day. (For chronic, day-to-day anxiety, other options are usually a better fit.)
How fast does it work?
Taken about 30–60 minutes before an event, propranolol’s calming effect on the body lasts a few hours. Because it works on the body rather than the brain, it doesn’t make you drowsy or “foggy” the way some anxiety medicines can.
Common side effects
Propranolol is generally well tolerated at the low doses used for anxiety. Possible side effects include:
- Tiredness or low energy
- Dizziness or lightheadedness
- Cold hands or feet
- A slower heartbeat or lower blood pressure
If you feel faint or very lightheaded, let your prescriber know.
A note on dosing
For anxiety, propranolol is usually taken as a low, as-needed dose before a specific event. Your prescriber sets the right dose and approach; this page intentionally doesn’t give a specific number.
Who should be cautious
Propranolol is not for everyone. It’s generally avoided in people with asthma or certain lung conditions (it can trigger breathing problems), and in some heart-rhythm or blood-pressure conditions — so your prescriber will review your heart and lung history first. It can also interact with other medications. It is not addictive.
If you take it daily, don't stop abruptly
If you’re taking propranolol on a regular daily schedule (rather than occasionally), don’t stop it suddenly — that can cause a rebound spike in heart rate and blood pressure. Taper off with your prescriber. (Occasional, as-needed use for events doesn’t carry this concern in the same way.)
