The Indian Pharmacopoeia Commission has warned that beta-blockers, commonly prescribed for irregular heartbeat and hypertension, can cause hypokalaemia or dangerously low potassium levels. The alert stresses monitoring for adverse reactions and encourages reporting them. Elderly and diuretic-using patients should be especially cautious, though such side-effects are rare. Cardiologists advise careful use and monitoring of these drugs.
