An osteoarthritis drug called Prexige has been taken off the shelves and can no longer be sold in Canada after Health Canada decided to pull the product. The drug was approved in November 2006 as a treatment for osteoarthritis of the knee and later was approved to treat general osteoarthritis symptoms in adults.

However, patients -- including two in Canada -- began reporting serious liver problems after taking the drug. Australia was the first country to pull Prexige and the United States rejected the drug altogether due to concerns over these side-effects.

Those who have been prescribed Prexige who want more information on the story can look here, and should visit their doctors in order to find an appropriate treatment to replace the drug.
