About This Medication

What the Medication is Used For

Silkis is used for the topical treatment of mild to moderate psoriasis on your body.

What it Does

Silkis contains the active ingredient calcitriol, a vitamin Dlike agent.

Psoriasis results from skin cells growing and multiplying too quickly, causing plaques (scaly, red patches) to form on your skin. Calcitriol acts in a way that aims to return the growth of skin cells to normal.

When it Should not be Used

Silkis should not be used if you:

  • Are allergic to calcitriol, or any medications that contain a vitamin D-like agent (vitamin D derivative), or any of the other ingredients in Silkis.
  • Have high blood calcium levels (hypercalcemia);
  • Are being treated for conditions affecting normal calcium levels (abnormal calcium metabolism).
  • Have severely reduced kidney function or end-state kidney disease.

Silkis should not be used in or near your eyes or on your face. Silkis should not be used internally (e.g. orally or intravaginally).

What the Important Nonmedicinal Ingredients Are

Warnings and Precautions

The ointment component of Silkis may increase the risk of developing skin tumours caused by ultraviolet radiation (UVR). Silkis ointment alone does not cause cancer. Avoid excessive exposure of areas being treated with Silkis to either natural or artificial sunlight, including tanning booths and sun lamps.

BEFORE you use Silkis talk to your doctor or pharmacist if:

  • You have severe extensive psoriasis or other forms of psoriasis (the use of Silkis is not recommended).
  • You receive other treatments for psoriasis or other skin conditions.
  • You have liver or kidney disease.
  • You are pregnant or planning to become pregnant
  • You are breastfeeding or plan to breastfeed an infant.
  • You are using sun tanning beds or sun lamps

Silkis is not recommended for use in patients under 18 years of age.

It is not recommended to use Silkis with an occlusive dressing, such as a bandage, or to cover the treated area(s) tightly

Interactions With This Medication

Before using Silkis, tell your doctor or pharmacist about your other medications, including non-prescriptions, vitamin or mineral supplements. Drugs that may interact with Silkis include:

  • Medications that may increase blood calcium levels, such as thiazide (water pill) and calcium supplements.
  • Medications that may change blood calcium levels, such as digoxin.
  • High doses of vitamin D.

Silkis has a slight irritant potential, and therefore it is possible that use of peeling agents, astringents, or other irritants at the same time may make the irritation worse.

Proper use of this Medication

Usual Dose

Apply Silkis to the skin areas affected with psoriasis twice a day (morning and evening) after washing and gentle drying. Rub the ointment in carefully until you can no longer see it.

Do not apply Silkis to more than 35% of your body area each time. Do not use more than 30 grams of Silkis ointment per day. After applying the ointment, wash your hands thoroughly with soap and water. Do not bandage or cover the treated area tightly.

You will not get better or faster results by applying Silkis more often. If more than the recommended amount of medication is used, marked redness, peeling or discomfort may occur.

Once your psoriasis improves your doctor may ask you to stop using Silkis. If your psoriasis returns, treatment may be re-started.


Excessive use or accidental ingestion of Silkis may result in signs of high blood calcium levels such as upset stomach, excessive thirst, and increased urination. If you have overdosed, contact your local poison control centre or contact your physician or pharmacist.

Missed Dose

If you miss a dose, apply it as soon as you remember. Then go back to your usual dosing schedule at the next dose.

Side Effects and What to do About Them

The most common side effects with Silkis are skin discomfort, itching, psoriasis, flu syndrome and skin infection. Silkis may affect the results of certain laboratory tests or the level of calcium in your urine (hypercalciuria).
