Pfizer Canada is recalling all lots of Inderal-LA (propranolol hydrochloride) extended release capsules, in 60 mg, 80 mg, 120 mg and 160 mg strengths, due to the presence of a nitrosamine impurity (N-nitroso-propranolol) above the acceptable level.
Inderal-LA is a prescription medication known as a beta-blocker. It is used in adults to treat high blood pressure and prevent angina pectoris (a condition associated with sharp chest pain and difficulty breathing, often associated with exercise).
Nitrosamines are common in water and foods, including cured and grilled meats, dairy products and vegetables. Nitrosamine impurities may increase risk of cancer if people are exposed to them above acceptable levels and over long periods of time.
Health Canada advises that patients contact their health care provider to discuss other treatment options.
They add that while there are no other companies marketing extended release propranolol in Canada, immediate release propranolol products are available, along with other treatment options, so patients should continue taking their medication unless advised to stop by their health care provider. Not treating your condition poses a greater health risk.
Patients can call Pfizer Canada ULC at 1-800-463-6001 or online for medical inquiries and at 1-800-387-4974 for general inquiries if you have questions about the recall.
