Tacalcitol is used to treat plaque psoriasis - this is the most common type of psoriasis. It is a condition where red scaly patches develop on your skin, called plaques. The most common areas affected are over your elbows and knees, the scalp and the lower part of your back. The patches may vary in size from time to time and can be itchy. Treatment for psoriasis aims to clear the plaques as much as possible.

Psoriasis is caused by cells in the outer layer of your skin multiplying faster than normal. This causes the older and dead skin cells to build up on the surface of your skin, causing the red scaly patches. Tacalcitol works by slowing this overproduction of skin cells which eases the inflamed, scaly areas. It is similar to vitamin D, which is a vitamin essential for healthy skin.

To make sure that this is the right treatment for you, before you start using tacalcitol it is important that your doctor knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have been told you have a form of psoriasis known as erythrodermic or pustular psoriasis. This is because more severe forms of psoriasis like these should only be treated with close supervision of a skin specialist doctor.
  • If you have been told you have high calcium levels in your blood, or if your body has problems processing calcium.
  • If you are taking any other medicines or using any other skin preparations. This includes any medicines which are available to buy without a prescription, such as herbal and complementary medicines.
  • If you have ever had an allergic reaction to a medicine.
  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about applying tacalcitol and will provide you with a full list of the side-effects which you could experience from using it.
  • Apply a thin layer of ointment or lotion once each day. It is recommended that you apply it in the evening before you go to bed. If you are using the ointment on your scalp, it can be shampooed out the next morning. If you are using the lotion on your scalp, apply a few drops close to the affected area and rub it in gently.
  • You should not use more than 10 g of tacalcitol ointment per day or more than 10 ml of the lotion a day. This is because tacalcitol is absorbed through your skin and can cause problems if more than these amounts are used. If you are using both ointment and lotion, the maximum amount of each is less than these amounts. If this applies to you, your doctor will give you instructions for the maximum amount of each to use.
  • Wash your hands well afterwards. This will help prevent tacalcitol getting on to any areas of your skin which are unaffected by psoriasis.
  • Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress.
  • If you are also using a moisturiser for your skin, use this first and then wait until it has soaked into your skin before you apply tacalcitol.
  • IIf you have been advised to use tacalcitol on your face, apply it carefully so that you do not get any into your eyes. Also, remember to apply a thin layer only, as there is a greater chance it could cause irritation on your face.
  • You should start to see an improvement in your skin within a few weeks. This improvement will continue for a further few weeks until you feel the full benefit. Continue to apply tacalcitol regularly for as long as you have been recommended so that you get the full benefit.
