A new option in the fight against psoriasis -- Stelara (ustekinumab). The FDA -- after two long years of talks -- has approved the use of this drug for psoriasis patients who are candidates for phototherapy or systemic treatment, reports MedPage Today. It is to be used for moderate to severe cases. In trials, patients who followed the regimen recommended were able to achieve significantly clear skin for about a year. This is an injectible drug. A few heads up before you talk to your doctor and seek Stelara -- use may cause the immunosupression, and you'll need a TB test before starting to use it.
