This medication is used to treat psoriasis. Calcitriol is a form of vitamin D. It works by slowing down the growth of cells.

Read the Patient Information Leaflet if available from your pharmacist before you start using calcitriol and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Use this medication on the skin only. Wash the affected area and pat dry. Apply a thin layer of medication as directed by your doctor, usually twice daily (once in the morning and once in the evening). Apply only to the areas of skin affected by psoriasis. Gently rub in. Wash your hands after using, unless you are using this medication to treat the hands. Do not apply calcitriol to the face, in the eyes, nose, or mouth, or inside the vagina. If you do get the medication in those areas, flush with plenty of water.

Do not apply to a larger area of skin, apply more often, or use longer than prescribed. Your skin will not improve any faster and this may increase the risk of side effects. Discuss with your doctor the maximum amount of medication you may use per day (or per week). Do not cover, bandage, or wrap the area unless directed to do so by your doctor. Do not apply to more than one-third of your body.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day.

Tell your doctor if your condition does not get better or if it gets worse. You should usually begin to see an improvement in your skin condition after 4 weeks of treatment.

Pain, burning, itching, redness, or peeling at the application site may occur. If any of these effects last or get worse, notify your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
