Updated Labelling for Antibiotic Avelox (Moxifloxacin) Regarding Rare Risk of Severe Liver Injury
OTTAWA - Health Canada is informing health care professionals and Canadians of changes to the labelling information for the prescription antibiotic Avelox (moxifloxacin). The updated labelling incorporates important safety information related to the rare risk of severe liver injury.
Avelox belongs to a family of antibiotic drugs known as quinolones and is used to treat a broad range of bacterial infections, including respiratory infections. It can be taken by mouth in a tablet format, or administered by injection. Health Canada has conducted a safety review and concluded that Avelox may be associated with the rare but potentially life threatening risk of liver injury, including liver failure.
Symptoms of liver problems include abdominal pain, loss of appetite, yellowing of the skin and eyes, severe itching, dark urine, and pale-coloured stools. Patients who experience any of these symptoms are advised to stop taking Avelox and contact a health care professional immediately.
This information has been incorporated into the Warnings and Precautions section, and also in the Consumer Information section of the product monograph for Avelox.
Patients are invited to read the Consumer Information section of the Canadian Product Monograph to familiarize themselves with the safety information for this antibiotic. Patients with questions or concerns regarding the use of Avelox should talk to their pharmacist or physician.
