VHOSPITAL.CLINIC · Drug Reference
Labetalol dosing must be individualised to the patient's condition, weight, kidney and liver function, and other medications. Beta blockers are taken once or twice daily depending on the specific agent. Modified-release formulations allow once-daily dosing for some drugs. Doses are titrated based on heart rate and blood pressure.
Do not exceed the prescribed dose of Labetalol. If you miss a dose, follow the specific guidance provided with your prescription — generally take it as soon as you remember unless it is nearly time for the next dose.
Can I take a higher dose of Labetalol if my symptoms don't improve?
No. Never increase the dose of Labetalol without medical advice. If your current dose is insufficient, contact your healthcare provider to discuss a dose adjustment or alternative treatment.
Why can't I stop my beta blocker suddenly?
Long-term beta blockade causes upregulation of beta receptors. Sudden discontinuation leads to receptor hypersensitivity, which can cause rebound tachycardia, hypertension, and angina — potentially triggering a heart attack. Always taper gradually under medical supervision.
Describe your symptoms and concerns and get a structured clinical assessment — possible causes, red flags, and recommended next steps.
