Calcitriol topical belongs to the class of medications known as vitamin D analogues. It is also known as a nonsteroidal antipsoriatic agent. Calcitriol topical is used to treat mild to moderate plaque-type psoriasis (skin condition) involving up to 35% of the body surface area.
This medication works by controlling the excessive production of skin cells seen in psoriasis, thereby eliminating the red, scaly patches seen in the skin condition. You may notice an improvement after about 2 weeks of treatment.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.
Each g of white, translucent, ointment contains 3 µg (0.0003% w/w) of calcitriol. Nonmedicinal ingredients: vitamin E (dL-α-tocopherol), mineral oil, and white petrolatum.
Calcitriol topical should be applied to the affected areas with psoriasis twice daily, morning and evening. Do not use more than 30 g of this medication daily, and only use this medication if the affected body area is 35% or less.
Wash and gently dry the affected area. Gently rub in the ointment until it is no longer visible. Do not cover the area with bandage or any other materials. Wash your hands thoroughly with soap and water after each application. Once the psoriasis improves, your doctor may advise you to stop using calcitriol. Your doctor may advise you to use the medication again if the psoriasis lesions reappear.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Kidney or liver function: People with kidney or liver disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. People with severely reduced kidney dysfunction or end-stage renal disease should not use calcitriol topical.
Monitoring calcium levels: If you are at risk for having high calcium levels, your doctor will advise you to do blood tests regularly to check your calcium levels. If calcium levels in your blood are high, your doctor may advise you to stop using this medication and monitor you until your calcium levels return to normal.
Sun sensitivity: Calcitriol topical used alone does not cause cancer, but it may increase the risk of developing skin tumours caused by ultraviolet (UV) radiation. Limit your exposure to sunlight, tanning booths, and sun lamps. Use a sunscreen with at least a sun protection factor (SPF) of 15.
Use of medication: Calcitriol topical is for external use on the skin only. It is not to be used internally. Do not apply this medication to facial skin, eyes, or lips. This medication should also not be used for severe psoriasis that involves more than 35% of the body surface area. Certain medications can increase the absorption of calcitriol topical into the body, which can affect your blood calcium levels. Your doctor or pharmacist may advise you to avoid using these medications (see also, “What medications can interact with this medication?”).
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while you are on this medication, contact your doctor immediately.
Breast-feeding: It is not known if calcitriol passes into breast milk. If you are a breast-feeding mother and are using this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children under 18 years of age.
