How does it work?
- Dithrocream contains the active ingredient dithranol, which is a medicine applied to the skin to treat psoriasis.
- Psoriasis is a condition in which thickened, scaly patches or plaques of skin form. These are the result of excessive production of skin cells.
- Dithranol works by slowing down the process of skin cell production. It is applied only to the psoriasis plaques and not to normal healthy skin. The dithranol is absorbed into the skin cells and inhibits DNA replication in these cells. This slows down cell division and stops the cells from multiplying excessively. In turn, this reduces the thickening and scaling of the skin and clears up the psoriasis plaques.
- Dithranol can irritate and stain the skin, so the treatment is usually only applied for a short time every day. This is called 'short contact therapy'. The strength of dithranol used is gradually increased so that the skin becomes used to the treatment.
- Dithrocream comes in five different strengths: 0.1%, 0.25%, 0.5%, 1% and 2%. Treatment should start with the 0.1% cream on small patches of affected skin only. If your skin has not improved after one to two weeks and you don't have any signs of skin irritation, treatment can progress to the 0.25% strength. If necessary this can be followed by the 0.5%, the 1.0% and finally the 2.0% strength. However, the 2% strength is only available on prescription and should only be used under medical supervision. If your skin gets irritated by using any strength cream you should go back to using a lower strength.
- Dithrocream should be applied to the affected areas of skin once every 24 hours and should then be washed off, no more than 60 minutes after application. Alternatively, if you are using the 0.1%, 0.25% or 0.5% strength cream, you can apply the cream before going to bed, leave it on overnight and wash it off in the morning. (The 1% and 2% creams are too strong for this and should not be left on for longer than 60 minutes.)
- You can also use Dithrocream to treat psoriasis on the scalp. First comb the hair to remove any scales, then part the hair as necessary and rub the cream into the affected areas. Leave in contact for up to 60 minutes and then rinse off. Alternatively, if you are using the 0.1%, 0.25% or 0.5% strength cream, you can apply the cream before going to bed, leave it on overnight and wash it off in the morning. (As with treating the skin, the 1% and 2% creams should not be left on the scalp for longer than 60 minutes.)
- The daily treatment should be continued until the psoriasis plaques have cleared up, as long as your skin doesn't become irritated by the cream.
