When clinicians may prescribe propranolol

Propranolol belongs to the beta blocker class of medicines. A clinician may prescribe it for several problems, for example:

  • Control of certain cardiac rhythm disturbances and reduction of palpitations.
  • Reducing the risk of migraine recurring headaches when attacks are frequent or disabling.
  • Relief of prominent physical anxiety symptoms such as trembling hands and a racing pulse in performance situations.

Propranolol: proper way to take it

Follow the instructions on the prescription label coupled with the advice given by your doctor or pharmacist. Take your doses at the same times each day to keep blood levels stable. Small variations in timing are acceptable but try to be consistent.

How propranolol affects the body

Propranolol is a non-selective blocker of beta-adrenergic receptors. It reduces the influence of adrenaline-like substances on the heart and blood vessels, which can slow heart rate and reduce the force of contractions. These effects help control rhythm problems, reduce palpitations and often lower blood pressure. Because it affects multiple beta receptors, propranolol can also influence breathing, blood sugar responses and other systems; consult alerts for safety and precautionary measures for important safety reminders to remember.

Dose skipped protocol

Should you miss a dose, take it promptly when you remember, unless the next dose is due soon. If the next dose is near, skip the not taking my dose and continue the usual schedule. Do not use extra doses to replace a not taking my dose.

  • Active asthma or severe chronic obstructive pulmonary disease where bronchospasm is a major risk.
  • Severe peripheral vascular disease with critical ischemia in some patients.
  • Certain paediatric cardiac or metabolic conditions require specialist initiation and supervision.

Similar medications and an alternate possibility choices

Choice of an an additional choice depends on the condition being treated, other medical problems and health monitoring requirements. Do not switch or stop medicines without clinical advice.

  • Other beta blockers: bisoprolol, atenolol and metoprolol are more cardioselective options; nadolol and sotalol are multiple options for specific rhythm problems.
  • Calcium channel blockers: verapamil or diltiazem are options for rate control or angina in patients unsuitable for beta blockade.
  • Specific antiarrhythmic drugs: amiodarone or flecainide are specialist treatments for selected arrhythmias and usually require specialist supervision and vigilant monitoring.
  • Non-drug measures: reduce caffeine and alcohol intake, stress management, physiotherapy or procedural interventions where indicated.
