Sandoz Canada Inc., in consultation with Health Canada, is voluntarily recalling one lot of its health product, glimepiride, that is used to treat diabetes, due to the mislabelling of boxes. While the outer carton of the product is labelled as containing 1 mg tablets, the blister package inside may contain 2 mg tablets. This potentially poses a serious risk to consumers as a greater than prescribed dose of glimepiride can cause hypoglycemia (low blood sugar). Elderly patients are at increased risk of hypoglycemia, and their symptoms may be harder to notice. Symptoms include weakness, drowsiness, blurred vision, headache, sweating and confusion. In extreme cases, hypoglycemia may cause loss of consciousness, seizures, or death. No adverse reactions related to this problem have been reported to Health Canada or Sandoz Canada Inc.
