This safety review evaluated the potential risk of thrombotic microangiopathy associated with the use of Avonex. Health Canada's review concluded that there is evidence of a potential link between Avonex and the risk of thrombotic microangiopathy. Health Canada has requested that the manufacturer update the Canadian prescribing information to include this risk. Health Canada will continue to monitor this issue.
This safety review evaluated the potential link between serious hypersensitivity reactions and over-the-counter topical acne products containing either benzoyl peroxide or salicylic acid. Health Canada concluded there was evidence supporting a link between the use of over-the-counter topical acne products containing either benzoyl peroxide or salicylic acid and serious hypersensitivity reactions. Health Canada will update the directions of use and warnings sections of the Health Canada Acne Therapy Monograph for these products. Health Canada has also communicated this information to Canadians.
This safety review further evaluated the risk of serious breathing problems in children and adolescents treated with codeine prescription products for cough. Health Canada maintains its warnings and recommendations to manage the risk of serious breathing problems and death, that codeine prescription products not be recommended in children less than 12 years of age. Health Canada will continue to monitor this issue.
Shoppers Drug Mart, in consultation with Health Canada, voluntarily recalled Life Brand Instant Read Digital Temple Thermometers (Model No. 057800711568), due to some devices displaying temperatures that are lower than actual body temperatures.
This safety review evaluated the potential risk of suicidality associated with the use of finasteride. Health Canada's review concluded that the evidence was too limited to determine whether or not a link between finasteride and suicidality exists. Health Canada will continue to monitor this issue. Health Canada has also communicated this information to healthcare professionals.
This safety review evaluated the potential risk of autoimmune diseases and cardiovascular diseases associated with the use of Gardasil. Health Canada's review did not find any new safety issues concerning Gardasil. Health Canada has communicated this information to Canadians and will continue to monitor this issue. The safety of all vaccines, including Gardasil, is under continuous monitoring by Health Canada and the Public Health Agency of Canada.
Fourteen health products manufactured by Hospira had incorrect, outdated or missing safety information on the inner/outer labels and/or package insert of certain lots. The labels on the products and/or the package inserts are being corrected as soon as possible to include the most updated information approved by Health Canada.
This safety review evaluated the potential risk of neurological side effects associated with the use of melatonin in the pediatric population (newborn to 18 years old). Health Canada's review concluded that there is limited data about neurological side effects associated with the use of melatonin in the pediatric population. Health Canada will continue to monitor this issue.
Reports of infection have been associated with the use of System 83 Plus reprocessing devices in the United States. An infection could result from inadequate reprocessing of complex endoscopes such as duodenoscopes with a closed elevator (lifter) channel. At this time, it is recommended not to use the System 83 Plus device to reprocess complex endoscopes and to use an alternative method.
Health Canada seized five unauthorized drugs from retailers in British Columbia and Ontario. The products were labelled to contain prescription drugs, a narcotic or found to contain a prescription drug that was not listed on the label. The seized products have not been approved by Health Canada.
Health Canada advised Canadians that several clinics in Ontario and at least one in Québec are currently using illegally imported medical devices, Cryosaunas, which are potentially linked to a death in the US. Health Canada has requested that the manufacturer stop the sale and immediately recall the unlicensed medical devices.
Cases of radiation sensitization and radiation recall reaction have been reported in patients treated with radiation prior to, during, or following Zelboraf (vemurafenib) treatment. It is recommended that Zelboraf not be used concomitantly with radiation therapy, unless the potential benefit justifies the potential risk. New warnings have been added to the Canadian prescribing information for Zelboraf advising of this serious risk.
The following topics have been selected to raise awareness and, in some cases, to stimulate reporting of similar adverse reactions.

Adverse reactions (ARs) to health products are considered to be suspicions, as a definite causal association often cannot be determined. Spontaneous reports of ARs cannot be used to estimate the incidence of ARs because ARs remain underreported and patient exposure is unknown.
Due to time constraints relating to the production of this publication, information published may not reflect the most current information.
