Propranolol Dosing for Anxiety
For adults with anxiety, propranolol 20-40 mg orally 2-3 times daily is the recommended starting dose, with typical effective doses ranging from 80-240 mg daily in divided doses, though evidence supporting its use specifically for anxiety disorders remains limited.
Evidence Base and Limitations
The available evidence for propranolol in anxiety is notably weak. No major clinical practice guidelines specifically recommend propranolol for anxiety disorders. The 2023 Japanese guidelines for social anxiety disorder 1 recommend SSRIs and SNRIs as first-line pharmacotherapy, with cognitive behavioral therapy as the primary psychotherapy—beta-blockers are conspicuously absent from these recommendations.
The most recent systematic review and meta-analysis 2 (2025) found no evidence for beneficial effects of beta-blockers compared with placebo or benzodiazepines in patients with social phobia or panic disorder (p ≥ 0.54 for all comparisons). This directly contradicts the increasing prescription trend and highlights a significant evidence-practice gap.
Practical Dosing When Used Off-Label
Despite limited evidence, when clinicians choose to use propranolol for anxiety (particularly performance anxiety or somatic symptoms):
Starting Regimen
- Initial dose: 20-40 mg orally, 2-3 times daily 3, 4
- Adjust every 2-3 days based on response
- Target: resting heart rate of 55-60 bpm 5
Maintenance Dosing
- Typical effective range: 80-240 mg daily in divided doses 6, 3
- Some patients required 80-320 mg daily in older studies 4
- Maximum: 320 mg daily in patients without ascites 5
Performance Anxiety (Situational Use)
- Single dose: 20-40 mg taken 1-2 hours before the anxiety-provoking event 7, 8
- The 20 mg dose provides significant anxiety reduction with minimal side effects 7
Clinical Context and Contraindications
Absolute Contraindications
- Asthma or obstructive pulmonary disease 9, 10, 9
- Sinus bradycardia (heart rate <55-60 bpm)
- Second- or third-degree heart block 11
- Decompensated heart failure 9, 10
- Cardiogenic shock 11
- Severe peripheral arterial insufficiency 5
Relative Contraindications Requiring Caution
Important Caveats
The evidence supporting propranolol for generalized anxiety disorders is insufficient. Older studies 12, 4 showed some benefit, but these had significant methodological limitations including small sample sizes, high risk of bias, and missing data 2.
Propranolol may be most appropriate for:
- Anxiety with prominent somatic/autonomic symptoms (tremor, palpitations, sweating) 12, 8
- Performance anxiety or specific situational phobias 8
- Patients who cannot tolerate or have contraindications to first-line treatments (SSRIs, SNRIs, benzodiazepines)
Common side effects include dizziness, fatigue, insomnia, hypotension, and bradycardia 9, 10, 12—many of which overlap with anxiety symptoms themselves, making assessment challenging.
Monitoring Requirements
- Blood pressure and heart rate before each dose adjustment
- Assess for depression (reported in some patients) 8
- Evaluate effectiveness after 4-6 weeks 3
- If ineffective by 4-6 weeks at maximum tolerated dose, discontinue and consider alternatives
Do not abruptly discontinue propranolol, as this may precipitate rebound anxiety or cardiovascular events; taper gradually over several weeks 5, 3.
