Daivonex (Calcipotriol) aka Daivonex, Psorcutan, Dovonex, Sorilux - ointment is used to treat psoriasis. It contains calcipotriol which is a synthetic vitamin D3 which works by reducing the production of skin cells. Psoriasis usually causes the skin to thicken and become scaly, therefore increased skin cells are produced. Calcipotriol aids in decreasing the excessive skin cell production and facilitate normal skin cell growth. Daivonex allows the skin to flatten and to clear up psoriasis plaques.
