Health Canada is advising Canadians that Pharmascience Inc. has initiated a voluntary recall of one lot of pms-Atenolol 100 mg, used to treat cardiovascular conditions such as hypertension (high blood pressure), due to a labelling error. The lot contains foil blister packs incorrectly labelled as pms-Atenolol 50 mg with the wrong Drug Identification Number (DIN). The information on the outer package is correct.

The labelling error could result in a patient taking a double dose of the product. This could result in excessively low blood pressure and decreased heart rate, particularly in elderly patients and patients with impaired kidney function, which may cause dizziness, fainting and falling. Other symptoms could include drowsiness, tiredness, nausea and diarrhea.
