Further information

Take special care with 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 hypersensitive reaction
occur, the treatment should be discontinued and the
doctor contacted.
• There is no experience with the use of Silkis in children.
Therefore, use in children should be avoided.
• 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.

Taking other medicines:

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

Silkis might interfere with other medicines such as:
• Thiazide diuretics as their use jointly with this medicine
would increase your blood calcium levels.
• Calcium supplements or high doses of vitamin D.
• Peeling agents, astringent agents or irritant agents,
because additional irritant effects might occur.

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

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