Monthly recap of health product safety information
Alaris Infusion Sets
Becton Dickinson (BD) has recalled affected lots of the Alaris Pump Infusion Sets due to a manufacturing defect that can cause unintended delivery which can result in over-infusion. BD has requested Canadian facilities to remove and destroy all affected products and is investigating whether additional lots may be affected. Healthcare professionals should only use Alaris Pump Infusion Sets that have not been identified as part of the affected lots and follow the instructions provided in the communication.
One lot of Auro-Irbesartan HCT (irbesartan/hydrochlorothiazide) tablets was recalled because of a nitrosamine impurity, N-nitrosodiethylamine (NDEA). NDEA is classified as a probable human carcinogen. The affected lot was released in August 2018 and distributed only in Ontario and Quebec.
In a recent post-marketing study, depression, suicidal ideation or behaviour, and self-injury were reported more frequently in patients receiving Benlysta plus standard therapy, when compared to patients taking placebo plus standard therapy. Healthcare professionals are advised to follow the recommendations provided in the communication. Health Canada is currently working with the manufacturer to update the Canadian product monograph for Benlysta regarding this risk.
Biocell breast implants
Health Canada advised Allergan that the Department intends to suspend its licences for Biocell breast implants. This is being done as a precautionary measure to protect Canadian patients from the rare but serious risk of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). Health Canada continues to monitor and review all available scientific and clinical information regarding the safety of textured breast implants. Canadians and healthcare professionals will be informed of any further decisions related to the licensing of Biocell breast implants. Since this communication, Health Canada has suspended the licences for Allergan's Biocell breast implants.
Foreign health products
These foreign health products have been found by regulators in the United States and Australia to contain undeclared drug ingredients which may pose serious health risks. The products are not authorized for sale in Canada and have not been found in the Canadian marketplace, but it is possible they may have been brought into the country by travellers or purchased over the Internet.
This safety review evaluated the risk of gastric and esophageal perforation, acute pancreatitis, and spontaneous balloon overinflation associated with intragastric balloons (IBs). Health Canada's review of the available information has confirmed a link between the use of fluid-filled IBs and all of the risks previously mentioned. Health Canada will work with the medical device manufacturers to strengthen the Instructions for Use for all fluid-filled IBs by including these potential risks. Health Canada has also communicated this information to healthcare professionals.
Mifegymiso (mifepristone and misoprostol)
The Canadian product monograph for Mifegymiso has been updated to reflect that an ultrasound is no longer required before the drug is prescribed. Previously, the product monograph indicated that an ultrasound was required before prescribing Mifegymiso to confirm the gestational age and to rule out an ectopic pregnancy. With the changes to the product monograph, prescribers now have the flexibility to use their medical judgement on how best to determine the gestational age and to rule out an ectopic pregnancy.
Unauthorized health products
Health Canada advised Canadians about various unauthorized health products being sold at retail locations across Canada or online that may pose serious health risks.
Advisory – Multiple unauthorized prescription drugs from Gigi's Market in Ottawa, Ontario
Advisory – Multiple unauthorized eye solutions and an acne gel in Lower Mainland, British Columbia
Advisory – Multiple unauthorized health products at Sunrise Lee Chinese Herbs Centre in Calgary, Alberta
Advisory – Unauthorized products sold by A1 Herbal Ayurvedic Clinic Ltd.
Update – Multiple unauthorized health products
New health product safety information
The following topics have been selected to raise awareness and, in some cases, to stimulate reporting of similar adverse reactions.
Fentora (fentanyl citrate, buccal/sublingual effervescent tablets) safety reminders
Fentora (fentanyl citrate, buccal/sublingual effervescent tablets) is indicated only for the management of breakthrough pain in cancer patients 18 years of age and older who are already receiving and who are tolerant to continuous opioid therapy for their persistent baseline cancer pain. Footnote 1 It has been available in Canada since May 2014.
In an ongoing effort to ensure the safe and effective use of medications, Health Canada has reviewed 2 surveys of Fentora prescribers in Canada, which were conducted by the manufacturer. These surveys indicated that some prescribers did not demonstrate a full understanding of the risks of respiratory depression, coma and death when Fentora is used concomitantly with central nervous depressant drugs such as benzodiazepines.
Health Canada would like to remind healthcare professionals of the following important safety and usage information related to the risks of respiratory depression, coma and death that is in the Fentora Canadian product monograph.
Fentora therapy should only be initiated in patients 18 years of age and older who are opioid tolerant and should only be used for the management of breakthrough cancer pain.
Fentora must not be used in opioid non-tolerant patients including those using opioids intermittently, on an as needed basis, because life-threatening respiratory depression and death could occur at any dose in patients not on a chronic regimen of opioids.
Patients considered opioid-tolerant include those taking:
- at least 60 mg of oral morphine daily; or
- at least 25 μg/hr of transdermal fentanyl; or
- at least 30 mg of oral oxycodone daily; or
- at least 8 mg of oral hydromorphone daily; or
- at least 25 mg oral oxymorphone daily; or
- an equianalgesic dose of another opioid daily for a week or longer.
Co-administration of Fentora with central nervous system (CNS) depressants, including benzodiazepines, or with cytochrome P450 3A4 (CYP3A4) inhibitors, may result in respiratory depression, hypotension, profound sedation, coma and death.
Fentora should be used with caution and in a reduced dosage during concomitant administration with CNS depressants such as:
- Benzodiazepines, other opioid analgesics, general anesthetics, phenothiazines and other tranquilizers, sedative-hypnotics, antidepressants, antipsychotics, antihistamines, centrally-active anti-emetics, and other CNS depressants (including alcohol and illicit drugs).
Concomitant use of Fentora with CYP3A4 inhibitors may increase the plasma concentration of fentanyl, resulting in increased depressant effects. If concomitant use is necessary, consider dosage reduction of Fentora until stable drug effects are achieved. Monitor patients for respiratory depression and sedation at frequent intervals. CYP3A4 inhibitors may include:
- Indinavir, nelfinavir, ritonavir, clarithromycin, itraconazole, ketoconazole, nefazodone, saquinavir, telithromycin, aprepitant, diltiazem, erythromycin, fluconazole, grapefruit juice, verapamil, or cimetidine.
It is also important to note that patients should not discontinue Fentora without first talking to their physician. Withdrawal (abstinence) symptoms may occur following abrupt discontinuation of therapy. Patients on prolonged therapy should be withdrawn gradually from the drug if it is no longer required.
Health Canada will continue to monitor safety information involving Fentora, as it does for all health products on the Canadian market, to identify and assess potential harms. Healthcare professionals should be aware that Canadian product monographs are updated periodically as required and are available from the manufacturer or on Health Canada's Drug Product Database. Healthcare professionals are also encouraged to report to Health Canada any adverse reaction suspected of being associated with the use of Fentora.

Illegal marketing of drugs and devices
When making decisions about treatments for patients, healthcare providers consider many different information sources, including marketing materials. Health Canada is responsible for ensuring compliance with the legislation and regulations that apply to drug and device advertisements. To be compliant, information in health product marketing materials should not be false, misleading or deceptive, and should accurately convey the benefits and risks of a health product.
To learn more about illegal advertising and marketing in Canada, visit the Health Canada Stop Illegal Marketing of Drugs and Devices Web page.
The following cases have been selected to raise awareness and to stimulate reporting of illegal marketing. If you encounter any situations involving the dissemination of misleading or unauthorized health product claims, please report to Health Canada at: firstname.lastname@example.org.
Health Canada has become aware of the dissemination of false and misleading information for the following onychomycosis treatment options:
Jublia (efinaconazole topical solution)
Healthcare professionals may have received brochures containing information on Jublia that is inconsistent with the Canadian product monograph, with an unauthorized use of a logo of a Health Canada recognized advertising preclearance agency, misleading healthcare professionals to believing that the brochure has been precleared and was compliant with Health Canada's requirements. In addition, the product has been illegally marketed directly to consumers through brochures, educational Web sites, and television.
Healthcare professionals are reminded that:
- Jublia, a triazole antifungal agent, is indicated for the topical treatment of mild to moderate onychomycosis (tinea unguium) of toenails without lunula involvement due to Trichophyton rubrum and Trichophyton mentagrophytes in immunocompetent adult patients. Footnote 3
- Direct-to-consumer advertising of prescription drugs beyond name, price and quantity is prohibited as per section C.01.044 of the Food and Drug Regulations.
Laser treatment for onychomycosis
Over 60 clinics and numerous vendors in Canada have been involved in the dissemination of false or misleading claims of laser-based medical devices for the treatment of onychomycosis.
Healthcare professionals are reminded that:
- Health Canada has authorized some laser-based medical devices for "temporary increase of clear nail in patients with onychomycosis." These devices are NOT authorized for claims such as "treatment of onychomycosis" or "destruction of nail fungus."
- Statements indicating or implying Health Canada's authorization may only be used for claims that are in line with the authorized indications. To confirm the authorized indications for a medical device, please contact the Medical Devices Bureau at email@example.com.
