Experts are raising alarms about the increasing use of propranolol, a low-cost beta-blocker, for managing anxiety symptoms. Marketed as a way to 'take the edge off' midlife anxieties, the drug, available for as little as £1.20, has seen a steady rise in prescriptions.
In the year leading up to June 2026, 8.4 million prescriptions for propranolol were dispensed, according to data cited by the Daily Mail. This surge has prompted concerns from health professionals about potential life-threatening risks associated with its off-label use for anxiety.
Propranolol, originally developed to treat high blood pressure, functions by blocking the effects of adrenaline on the heart. This action slows the heart rate and lowers blood pressure, which can alleviate physical anxiety symptoms like a racing heart, shaking, and sweating. However, this same mechanism can lead to dizziness, weakness, and fainting in susceptible individuals.
While propranolol is a legitimate medication for conditions such as high blood pressure and certain heart problems, its widespread adoption for anxiety without a formal prescription or medical supervision poses significant dangers. Health experts emphasize that using medication without proper diagnosis and guidance can lead to adverse health outcomes.
