Your doctor has prescribed one of the following medications for you:
Topical vitamin D derivatives can be used to treat psoriasis, an inflammatory condition of the skin with increased turnover of skin cells, creating red, scaly patches of skin. The medication works by slowing down cell growth in the skin. The addition of steroids in the medication helps to reduce the signs of inflammation (such as redness, swelling) at the same time.
This medication may also be used for other conditions as determined by your doctor.
