• Who this is for: General public

Health Canada is advising the public that Gilead Sciences Incorporated recalled two lots (032168 and 033357) of the cystic fibrosis drug Cayston (aztreonam) (DIN 02329840) on March 1, 2023, due to the potential of cracked glass vials in those lots, which may introduce glass particles into the medication. A cracked glass vial could cause potential injury or lead to potential contamination or a reduced dose.

Cayston is a prescription antibacterial medicine used for the management of chronic infections in cystic fibrosis patients. It is a powder that needs to be reconstituted by adding a sterile diluent (0.17% sodium chloride) before inhaling it through a device (Altera Nebulizer System).

Product contamination may lead to localized lung infections, such as pneumonia, or systemic complications, such as bacterial sepsis. Patients with weakened immune systems or abnormal lung function, such as those with cystic fibrosis, may be at higher risk. Glass particles in Cayston may cause local tissue irritation, and may lead to local tissue infections, or abscesses, if undiagnosed. A reduced dose or reduced efficacy may worsen the health status of patients under treatment, due to not controlling chronic infections.

The manufacturer has not received any customer complaints in relation to cracked glass vials in the recalled lots, or any other Cayston lots distributed in Canada. While the company continues to work with distributors and retailers to inform all affected individuals, Health Canada is communicating, as an additional measure, to mitigate any potential risk to health of Canadians. The Department is monitoring the company's recall and will inform the public if any new health risks are identified.
