Public Advisory
Health Canada Endorsed Important Safety Information on Arava (leflunomide)

June 21, 2004

Subject: Arava® (leflunomide) and lung inflammation causing difficulty breathing

Aventis Pharma Inc. in consultation with Health Canada would like to update you on Arava®, a drug indicated in adults for the treatment of active rheumatoid arthritis (RA), and spontaneous reports of lung inflammation causing difficulty breathing.

Rare spontaneous reports of lung inflammation occurring during treatment with Arava® have been received worldwide. Several of these cases had a fatal outcome.

Please note that it is difficult to determine whether lung inflammation causing difficulty breathing is specifically associated with Arava® because many people with RA develop lung inflammation whether or not they are being treated with medication. Other factors that can cause this condition were present in the patients such as pre-existing lung disease and use of other drugs known to induce lung inflammation, taken before or during Arava® therapy.

The prescribing information for Arava® is being revised to provide doctors and pharmacists with updated information regarding lung inflammation. The "Information for the Patient" section of the prescribing information will also be updated to ask you to tell your doctor without delay if you experience new or worsening of shortness of breath and/or cough, with or without associated fever, at any time while you are taking Arava®.

RA treatment should not be stopped without consulting your doctor. Stopping treatment may result in deteriorating RA control. People with RA who have any questions regarding their current prescription or treatment should contact their doctor or pharmacist directly.

This advisory is in addition to a letter issued to health care professionals reminding them of the above-mentioned information. The letter that was sent to health care professionals can be found on the Health Canada website.

Inquiries from patients and health care professionals should be directed to Aventis Pharma Inc. at 1-800-265-7927 between 9:00 am and 5:00 pm. For media inquiries, please contact Michel G. Tremblay, Aventis Pharma Inc., at (514) 956-4098.

The identification, characterization, and management of marketed health product-adverse reactions are dependent on the active participation of health care professionals in adverse reaction reporting programmes. Any occurrences of lung inflammation causing difficulty breathing or other serious and/or unexpected adverse reactions in patients receiving Arava® should be reported to Aventis Pharma Inc. or Health Canada at the following addresses:
