Overdosage

Taking any medicine in large doses can have severe consequences for your health. If you feel an overdose, contact your healthcare professional instantly.

Propranolol is known to cause severe toxicity when used in overdose. Therefore, patients should be informed of the signs of overdose and advised to seek urgent medical assistance if an overdose of propranolol has been taken.

Cardiac Clinical Features

Bradycardia, hypotension, pulmonary edema, syncope, and cardiogenic shock may develop. QRS complex prolongation, ventricular tachycardia, first to third degree AV block, ventricular fibrillation, or asystole may also occur. Cardiovascular complications are more likely if other cardioactive drugs, especially calcium channel blockers, digoxin, cyclic antidepressants, or neuroleptics, have also been ingested. Older patients and those with underlying ischaemic heart disease are at risk of developing severe cardiovascular compromise.

CNS

Drowsiness, confusion, seizures, hallucinations, dilated pupils, and in severe cases, coma may occur. Neurological signs such as coma or absence of pupil reactivity are unreliable prognostic indicators during resuscitation.

Bronchospasm, hyperkalemia, and occasionally CNS-mediated respiratory depression may occur.

What to Do in Case of Overdose

In cases of overdose, treatment with propranolol must be stopped. Treatment should include general symptomatic and supportive measures, including a clear airway and monitoring vital signs until stable. 

Early discussion with critical care should be considered in symptomatic patients or patients with abnormal ECG.

If You Forget about a Dose

If you miss the dose, try to take it as soon as you have the opportunity. If it is time for your next dose, take only one dose. You don’t have to double the dose.
