1. What Silkis is and what it is used for

Silkis is used for the topical treatment of mild to moderately severe plaque psoriasis with up to one third of body surface area involvement.

It contains an active ingredient, calcitriol (a vitamin D derivate), which inhibits and normalizes the unrestrained cell growth in psoriasis affected skin.

2. What you need to know before you use Silkis

Do not use Silkis:

  • if you are treated by systemic (oral) route for a calcium deficiency
  • if you have a kidney or liver disease
  • if you have high blood calcium levels or if you suffer from abnormal calcium metabolism
  • if you are allergic to calcitriol or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before using Silkis.

  • Carefully apply the ointment to the face, since it has a greater risk of irritation. Avoid contact with the eyes.
  • After using the ointment, wash your hands to prevent unintentional spread to non-affected zones.
  • Due to a potential effect on calcium metabolism, the ointment may not be applied under an occlusive wound dressing.
  • In case of severe irritation or allergic reaction occur, the treatment should be discontinued and the doctor contacted.
  • Although no significant hypercalcaemia (high blood calcium levels) was observed during clinical studies with this ointment, there is some absorption of calcitriol by the skin. This gives a risk of an increase of blood or urine calcium levels.
    This risk is minimal if you follow your doctor’s advice.

Children

There is no experience with the use of Silkis in children. Therefore, use in children should be avoided.

Other medicines and Silkis

Silkis might interfere with other medicines such as:

  • Thiazide diuretics as their use jointly with this medicine would increase your blood calcium levels.
  • Medications whose action can be modified by a change in calcium blood level such as digoxin
  • Calcium supplements or high doses of vitamin D.
  • Peeling agents, astringent agents or irritant agents, because additional irritant effects might occur.

Inform your doctor of any other topical treatment you may have used or you are using for your psoriasis lesions, before starting this treatment.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Silkis should not be used if you are breast-feeding.

Driving and using machines:

The treatment does not affect the ability to drive and use machines.

3. How to use Silkis

Silkis is an ointment for use on the skin only (cutaneous).

Always use this medicine exactly as your doctor has told you.

Check with your doctor or pharmacist if you are not sure.

Dosage instructions

  • First wash and dry the affected areas of your skin.
  • Apply a thin layer of Silkis over the affected areas to be treated twice a day, morning and evening before retiring, or as advised by your doctor.
  • Wash your hands after each application in order to avoid any contact with other non lesional areas.
  • Do not use more than 30 g of ointment per day and do not cover more than one third of your skin area (approximately one full arm and one full leg).

Do not swallow this product. If you accidentally do so, seek immediate medical advice.

Regularly follow your treatment, according strictly to your doctor’s instructions.

If you feel that the effect of this medicine is too strong or too weak, talk to your doctor or pharmacist.

If you use more Silkis than you should:

  • If the product is applied excessively, no more rapid or better results will be obtained and marked redness, peeling or discomfort may occur.
  • Always contact your physician to hear whether treatment or discontinuation is necessary if too much Silkis is used.
  • Hypotonia (decreased tension in muscles), nausea, vomiting, lack of appetite, constipation and depression may occur after using too much calcitriol. Therefore, contact your physician if these symptoms appear.

If you forget to use Silkis:

Do not apply a double dose to make up for forgotten individual doses.
