Why is this medication prescribed?
Calcitriol ointment is used to treat mild to moderate psoriasis (a skin disease in which red, scaly patches form on some areas of the body). Calcitriol ointment is in a class of medications called vitamin D analogs. It works by helping to stop the production of extra skin cells that may build up and form scales on the skin and by decreasing the activity of immune cells in the skin.
How should this medicine be used?
Calcitriol comes as an ointment to apply to the skin. It is usually applied two times a day, in the morning and evening. Apply calcitriol ointment at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Apply calcitriol ointment exactly as directed. Do not apply more or less of it or apply it more often than prescribed by your doctor. Your doctor will tell you how much ointment to apply. Do not use more than two tubes of calcitriol ointment per week.
Apply calcitriol ointment to the areas of skin affected by psoriasis. Do not apply calcitriol ointment to healthy skin or anywhere on your face, eyes, lips, or vagina. Do not swallow the medication.
Apply the ointment to the affected skin and gently rub the ointment into the skin until no medication is visible. Do not cover the skin where you applied calcitriol ointment with a bandage or dressing unless your doctor tells you that you should. Wash your hands well with soap and water after you apply calcitriol ointment.
