Propranolol: Comprehensive Clinical Guide

Primary Indications

Propranolol is indicated for cardiovascular conditions (hypertension, arrhythmias, angina, hypertrophic cardiomyopathy), infantile hemangiomas, situational/performance anxiety, migraine prophylaxis, essential tremor, hyperthyroidism symptom control, and portal hypertension bleeding prophylaxis. 1

Cardiovascular Uses

  • Hypertension: Propranolol is guideline-directed medical therapy but not first-line; ACE inhibitors, ARBs, calcium channel blockers, and thiazide diuretics are preferred initially 2
  • Supraventricular tachycardia (SVT): Effective for rate control when adenosine or vagal maneuvers fail, particularly when sympathetic tone is elevated 3, 1
  • Atrial fibrillation/flutter: Provides rate control through AV nodal blockade and increased refractoriness 1
  • Hypertrophic cardiomyopathy: Recommended for symptomatic patients with exertional gradients, doses up to 480 mg/day 1
  • Inappropriate sinus tachycardia: Highly effective for symptomatic relief, particularly in young women with anxiety-triggered tachycardia 4

Non-Cardiovascular Uses

  • Infantile hemangiomas: First-line systemic therapy with 60% complete/nearly complete resolution at 3.4 mg/kg/day for 6 months versus 4% with placebo 3, 1
  • Performance/situational anxiety: Highly effective for somatic symptoms (tremor, palpitations, sweating) when taken 30-60 minutes before events 2, 1
  • Ongoing anxiety: Effective at 80-160 mg/day in divided doses for chronic anxiety with prominent autonomic symptoms 2, 1

Absolute Contraindications

Screen for these conditions before any propranolol dose—presence of any one is an absolute contraindication: 2, 1, 4

  • Second- or third-degree atrioventricular block (without pacemaker)
  • Decompensated heart failure or severe left ventricular dysfunction
  • Cardiogenic shock
  • Sinus bradycardia or sinus node dysfunction (without pacemaker)
  • Asthma or obstructive airway disease (risk of life-threatening bronchospasm)
  • Severe hypotension
  • Known hypersensitivity to propranolol

Dosing Guidelines by Indication

Supraventricular Tachycardia

  • Acute IV: 1 mg over 1 minute, repeat every 2 minutes as needed, maximum 3 doses (total 3 mg) 3, 1
  • Oral maintenance: Start 30-60 mg/day divided or as single long-acting dose; maintenance 40-160 mg/day 2, 1

Atrial Fibrillation Rate Control

  • Immediate-release: 10-40 mg every 6 hours (3-4 times daily) 2, 1
  • Extended-release: 60-160 mg every 12 hours 1

Hypertension

  • Immediate-release: 80-160 mg/day divided into 2 doses (twice daily) 2
  • Long-acting: 80 mg once daily, titrate to 120-160 mg once daily 2
  • Maximum: 640 mg/day if needed 2

Performance/Situational Anxiety

  • Single-dose: 10-20 mg taken 30-60 minutes before event; maximum single dose 40 mg 2, 1
  • Not suitable for chronic daily use in this context 2

Ongoing Anxiety

  • Initial: 40 mg twice daily (80 mg total daily) 2, 1
  • Typical effective range: 80-160 mg/day in 2 divided doses 2, 1
  • Long-acting alternative: 80 mg once daily, titrate to 120-160 mg once daily 2

Infantile Hemangiomas

  • Initiation: Start 1 mg/kg/day, escalate to target 2-3 mg/kg/day (FDA-approved dose 3.4 mg/kg/day) 3, 1
  • Duration: Typically 6 months 3, 1
  • Administration: Divide into doses given no more than 8 hours apart (6 hours in infants <8 weeks); give with food 3, 2
  • Hospitalization recommended for: Infants ≤8 weeks, preterm <48 weeks postconceptional age, poor social support, cardiac/pulmonary risk factors 3

Hyperthyroidism

  • Symptom control: Doses spaced no more than 8 hours apart 2
  • Emergency IV: 0.15 mg/kg for rapid beta-blockade when urgent surgical preparation needed 2

Mandatory Pre-Treatment Assessment

Before initiating propranolol, obtain: 3, 2

  • Cardiovascular history: Screen for heart block, heart failure, bradycardia, hypotension, syncope
  • Respiratory history: Asthma, COPD, bronchospasm, wheezing
  • Metabolic history: Diabetes, hypoglycemia episodes
  • Physical examination: Heart rate, blood pressure, cardiac auscultation, lung auscultation
  • Medication review: Non-dihydropyridine calcium channel blockers (diltiazem, verapamil), dofetilide, CYP inhibitors

ECG and echocardiogram: Only needed in infants with cardiac examination abnormalities, family history of congenital heart disease, or segmental head/neck hemangiomas; routine cardiac screening has limited value in patients with unremarkable history/exam 3, 2

Critical Drug Interactions

Avoid Routine Combination

Non-dihydropyridine calcium channel blockers (diltiazem, verapamil): Markedly increased risk of severe bradycardia and heart block due to additive AV nodal blockade and CYP3A4 inhibition raising propranolol levels 3, 2, 1

Absolute Contraindication

Dofetilide: Propranolol is contraindicated with this antiarrhythmic 2

Use With Extreme Caution

Adenosine: Short half-life allows sequential use, but avoid overlapping with longer-acting AV nodal blockers 3

Adverse Effects and Monitoring

Common Adverse Effects

  • Cardiovascular: Bradycardia, hypotension, cold extremities 3, 2
  • Respiratory: Bronchospasm, wheezing (0.9-12.9% in pediatric series) 3
  • Neurological: Sleep disturbances, nightmares, night terrors (2-18.5%), fatigue, dizziness 3, 2
  • Gastrointestinal: Diarrhea, nausea 3
  • Metabolic: Hypoglycemia (especially in infants and diabetics) 3, 2

Signs of Excessive Beta-Blockade

Monitor for: 2

  • Heart rate <50 beats/min
  • Systolic blood pressure <90 mmHg
  • Dizziness, light-headedness, marked fatigue
  • New or worsening shortness of breath/wheezing

Hypoglycemia Risk Management

Propranolol masks adrenergic warning signs (tremor, tachycardia, sweating) of hypoglycemia: 3, 2, 1

  • Administer with food to reduce risk 3, 2
  • In infants: Feed at intervals ≤8 hours (≤6 hours if <8 weeks old) 3
  • In diabetics: Monitor glucose more frequently; rely on non-adrenergic cues (hunger, confusion, sweating) 2
  • Hold doses during vomiting, diarrhea, or reduced oral intake 3, 2

Post-Initiation Monitoring

  • Infantile hemangiomas: Reassess heart rate and blood pressure 1-2 hours after first dose and after any increase ≥0.5 mg/kg 2
  • Adults: No routine vital sign monitoring required between appointments if stable and asymptomatic 2

Discontinuation Protocol

Never abruptly discontinue propranolol after chronic use—this can precipitate rebound hypertension, tachycardia, or angina. 3, 2, 1

Taper gradually over 1-3 weeks when discontinuing. 3, 2, 1

Alternative Beta-Blockers

When propranolol is unsuitable, consider: 2

Clinical Situation Alternative Typical Adult Dosing
Renal dysfunction Metoprolol tartrate (cardioselective) 25 mg twice daily; max 200 mg twice daily
Once-daily dosing Metoprolol succinate (extended-release) 50 mg once daily; max 400 mg once daily
Renal impairment with once-daily dosing Atenolol 25-50 mg once daily; max 100 mg daily (reduce in severe renal impairment)
Renal impairment with once-daily dosing Nadolol 40 mg once daily; max 320 mg daily (reduce in renal impairment)

Note: Atenolol is less effective for blood pressure control and lacks proven benefit for anxiety 2

For reactive airway disease: Cardioselective beta-blockers (metoprolol, atenolol) may be used with extreme caution, but all beta-blockers retain some bronchospasm risk; non-dihydropyridine calcium channel blockers are not effective for tremor or anxiety 2

Special Populations

Pediatric (Infantile Hemangiomas)

  • Cardiology consultation if family history of congenital heart disease, though pretreatment screening has limited value with normal exam 3
  • Hospitalize for initiation if: age ≤8 weeks, preterm <48 weeks postconceptional age, poor social support, cardiac/pulmonary risk factors 3
  • Progressive improvement noted for at least 3 months; lightening and softening often within hours to days 3

Elderly

  • Lower doses may be required due to altered pharmacokinetics 2

Diabetics

  • Use with extreme caution; propranolol masks hypoglycemia symptoms 2, 1
  • Increase glucose monitoring frequency 2

Pharmacokinetics

  • Immediate-release half-life: 3-6 hours; requires 2-4 times daily dosing 2
  • Extended-release half-life: 8-20 hours; allows once-daily dosing 2
  • IV half-life: 2.4 hours 2
  • Metabolism: CYP2D6, CYP1A2, CYP2C19 2
  • Bioavailability: Long-acting formulation has 30-50% less bioavailability than immediate-release due to increased first-pass metabolism 5

Clinical Pearls

  • Pre-excited atrial fibrillation/flutter: AV nodal blockers (including propranolol) are contraindicated—may accelerate ventricular response; use antiarrhythmics instead 3
  • Dual indication (hypertension + performance anxiety): Maintain baseline antihypertensive dose and add supplemental 10-20 mg 30-60 minutes before events; max single situational dose 40 mg 2
  • Inappropriate sinus tachycardia: Predominantly affects women (90%), mean age 38; identify and address underlying cause first 4
  • Neurodevelopmental concerns: Large prospective trial showed no appreciable neurodevelopmental differences at 96 weeks in infants treated for hemangiomas 3
