If you have moderate to severe psoriasis elsewhere on your body, one of these medications may help:
Methotrexate slows an enzyme involved in the rapid growth of skin cells.
Oral retinoids help control the growth of cells.
Cyclosporine lowers the immune system function, and therefore helps to reduce the inflammation of psoriasis.
Biologics target specific parts of the immune system that are overactive in psoriasis. Talk with your doctor about the potential side effects of these treatments.
