Dolenio (Glucosamine Sulfate) is indicated for the relief of symptoms in mild to moderate osteoarthritis of the knee.
Dolenio is not indicated for the treatment of acute painful symptoms. Relief of symptoms (especially pain relief) may not be experienced until after several weeks of treatment and in some cases even longer. If no relief of symptoms is experienced after 2-3 months, continued treatment with Glucosamine should be revaluated
