Dear All,
I would like to add some more reasons for joint pains please see to this ::
Joint pains have been reported in 10-30% of patients receiving deferiprone. These usually involve knees, ankles, elbows, hip and the lower back. In a few patients the small joints of the hands and feet have been involved. In some patients swelling of the joints with effusion has been seen. The exact mechanism of this arthropathy is not known, but it appears to be by a mechanism other than immunological. Joint pains have been seen more commonly in patients with a higher serum ferritin and those on higher dose of deferiprone. These may be related to deposition of iron in the joints (due to the chelation process) leading to an inflammatory reaction in the joints. If joint pains occur, it may be necessary to stop the drug for a short while or reduce the dosage. The joint pains usually disappear and the drug may be restarted at lower doses. Concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibrupofen or diclofenac may be used to control the pain. In a few patients however, joint pains may recur on restarting the drug and thus such patients may be unable to tolerate the drug (See also Patient Monitoring).
