Migraine Prophylaxis with Propranolol

Introduction to Propranolol Therapy

• Propranolol has consistently demonstrated efficacy for migraine prevention at doses ranging from 80-240 mg/day, with the American College of Physicians recommending its use for migraine prophylaxis, based on evidence from the Annals of Internal Medicine 1

Dosing and Administration

• The recommended dose range for propranolol in migraine prophylaxis is 160-240 mg once daily for extended-release formulations, with a strength of evidence supported by the American Academy of Neurology 1
• Propranolol is more efficacious in patients with pure migraine headaches compared to those with mixed migraine and tension-type headaches, as stated by the American Headache Society 1

Patient Evaluation and Monitoring

• Cardiovascular and respiratory examination is required before starting propranolol, including auscultation, peripheral pulses, and abdominal examination, as recommended by the European Society of Cardiology 2

Adverse Effects and Contraindications

• Fatigue, depression, nausea, dizziness, and insomnia are commonly reported adverse effects of propranolol, with a strength of evidence supported by the National Institute of Neurological Disorders and Stroke 1

Special Considerations

• Propranolol extended-release capsules are not a simple mg-for-mg substitute for immediate-release tablets, and dosage should be adjusted accordingly, as recommended by the American College of Clinical Pharmacy 1
