Propranolol
Generic: propranolol hydrochloride · Brand: Inderal® / Inderal LA® · Class: Beta-Blocker (Off-Label for Anxiety)
🧠
How It Works
Propranolol is a non-selective beta-adrenergic blocker primarily used for heart conditions but widely used off-label for performance and situational anxiety. It works by blocking the physical symptoms of anxiety — racing heart, trembling, sweating, and flushing — rather than directly reducing the psychological feeling of anxiety. By interrupting the body's adrenaline response, it prevents the physical cascade that often amplifies anxiety. It does not cause sedation, has no abuse potential, and is not a controlled substance. It is ideal for situational anxiety (public speaking, presentations, medical procedures) where the goal is to prevent physical symptoms.

Dosing Overview
| Population | Start | Typical Range | Max |
|---|---|---|---|
| Adults Performance Anxiety | 10–40 mg as needed | 10–40 mg before event | 40 mg per event |
| Adults Ongoing anxiety (off-label) | 10–40 mg twice daily | 20–80 mg/day | 320 mg/day |
| Older Adults Start low | 10 mg as needed | 10–20 mg | 20 mg per event |
For situational use: take 30–60 minutes before the anxiety-provoking event. For scheduled use: taken twice daily. Take with food to improve absorption. Do not stop abruptly if using regularly — can cause rebound hypertension and heart rate changes.

Propranolol is unique in that it targets the physical symptoms of anxiety — not the psychological experience. Patients often find it helpful precisely because it breaks the feedback loop where physical symptoms (racing heart) amplify the psychological anxiety. It does not cause sedation or impair cognitive performance.

Important Safety Information
Asthma and COPD Contraindication: Propranolol is contraindicated in asthma and COPD — it can cause severe bronchospasm by blocking beta-2 receptors in the lungs. Tell your provider about any respiratory conditions.
Cardiovascular Conditions: Tell your provider about any heart conditions, low blood pressure, or slow heart rate. Propranolol significantly lowers both heart rate and blood pressure.
Drug Interactions: Interacts with many medications including other blood pressure medications, antiarrhythmics, and diabetes medications. Always share your full medication list.
Pregnancy: Use with caution — discuss risks and benefits. Associated with fetal growth restriction with long-term use.
Do Not Stop Abruptly (Regular Use): If taking propranolol regularly, never stop suddenly — can cause rebound hypertension, angina, and dangerous heart rate changes. Always taper with your provider.
