Calcipotriol is used for Plaque psoriasis (psoriasis vulgaris). Psoriasis is the result of excessive skin cell production. It produces raised plaques on the skin which can feel scaly and thicker than normal skin. Calcipotriol reduces the excess skin production and promotes healthy and normal skin growth. It helps to clear, and flatten the psoriasis plaques on the skin. The medicine will work over time with maximum improvement seen with up to 12 weeks of treatment. It comes in both a cream and ointment and your recommended dose will be stated to you by your doctor.
