Monthly recap of health product safety information

The following is a list of health product advisories as well as summaries of completed safety reviews published in December 2016 by Health Canada.

Direct-acting antivirals

This safety review evaluated the risk of hepatitis B virus (HBV) reactivation associated with direct-acting antivirals (DAAs): Daklinza (daclatasvir), Epclusa (sofosbuvir, velpatasvir), Galexos (simeprevir), Harvoni (sofosbuvir, ledipasvir), Holkira Pak (dasabuvir, paritaprevir, ombitasvir, ritonavir), Sovaldi (sofosbuvir), Sunvepra (asunaprevir), Technivie (paritaprevir, ombitasvir, ritonavir), and Zepatier (grazoprevir, elbasvir). Health Canada's review concluded that there may be a link between the risk of HBV reactivation in patients infected with both HBV and hepatitis C virus that have been treated with certain DAAs. Health Canada has recommended that the Canadian product monographs for all DAAs be updated to inform about this risk, as a precaution. Health Canada has also communicated this information to Canadians.

General anesthetics and sedatives

Health Canada is reviewing the safety of certain drugs used for general anesthesia and sedation in children under the age of three, or in pregnant women during their third trimester. This follows a recent communication by the U.S. Food and Drug Administration warning the public that repeated or lengthy use of general anesthetics and sedatives in these groups may have potential negative effects on the development of children’s brains. Health Canada will continue to update Canadians as the review is completed.
