Which β‑blocker is recommended for anxiety, including appropriate dosing regimens, contraindications, and alternative options?

Beta-Blockers Are NOT Recommended for Anxiety Disorders

Beta-blockers, including propranolol and atenolol, should not be used for the treatment of anxiety disorders based on current high-quality evidence showing they are ineffective and potentially harmful. 1

The Evidence Against Beta-Blockers

The most recent and authoritative guidance comes from the 2023 Japanese Society of Anxiety and Related Disorders/Japanese Society of Neuropsychopharmacology clinical practice guideline, which explicitly states that the Canadian Clinical Practice Guideline deprecates beta-blockers (atenolol and propranolol) based on negative evidence 1. This represents the strongest current guideline position.

A 2025 systematic review and meta-analysis—the highest quality and most recent evidence available—found no beneficial effect of beta-blockers compared with either placebo or benzodiazepines in patients with social phobia or panic disorder (p ≥ 0.54 for all comparisons) 2. This directly contradicts the increasing prescription trend and confirms the lack of robust evidence for effectiveness.

What Should Be Used Instead

First-line pharmacotherapy for anxiety disorders:

• SSRIs: Escitalopram and sertraline (preferred first-line) 1
• Alternative SSRIs: Fluvoxamine, paroxetine 1
• SNRIs: Venlafaxine 1
• Pregabalin: Listed as first-line in Canadian guidelines 1

Second-line options:

• Benzodiazepines (alprazolam, bromazepam, clonazepam) for short-term use only 1
• Gabapentin 1

The Limited Exception: Performance Anxiety Only

Beta-blockers may have a role exclusively for situational performance anxiety (e.g., public speaking, musical performance) when:

• Symptoms are predominantly somatic (tremor, palpitations, sweating)
• Use is infrequent and as-needed
• The situation is time-limited and predictable

Propranolol 20-40 mg taken 1-2 hours before the performance is the typical approach for this narrow indication 3, 4. However, this is distinct from treating anxiety disorders and represents off-label use 5.

Why Beta-Blockers Fail for Anxiety Disorders

The mechanism explains the failure: beta-blockers only address peripheral autonomic symptoms (tremor, palpitations) but do not treat the core psychological symptoms of anxiety disorders 4. While older, small studies from the 1980s-1990s suggested some benefit 6, 3, 4, 7, these have not been replicated in modern, adequately powered trials 2.

Important Caveats

• Propranolol adversely affects mood, increasing tension, depression, fatigue, and confusion 8
• The 2025 meta-analysis noted that many studies had small sample sizes, missing data, and high risk of bias 2
• Despite lack of evidence, beta-blocker prescriptions for anxiety increased substantially between 2003-2018, representing inappropriate prescribing 2

Recommended Treatment Algorithm

1. Start with SSRIs (escitalopram or sertraline) as first-line pharmacotherapy
2. Add or switch to venlafaxine if inadequate response
3. Consider cognitive behavioral therapy (14 sessions over 4 months, 60-90 minutes each) either alone or combined with pharmacotherapy 1
4. Reserve benzodiazepines for acute anxiety requiring sedation, short-term use only
5. Avoid beta-blockers for chronic anxiety disorders entirely
