Inderal is a beta-adrenergic blocking agent. It works by slowing down the heart and reducing blood pressure, which helps it pump more efficiently and reduces the workload on the heart.
Missed Dose
If a dose is missed, take it as soon as possible. If several hours have passed or if it is nearing time for the next dose, do not double the dose to catch up, unless advised by your doctor. If more than one dose is missed, contact your doctor or pharmacist.
