Psoriasis is a skin condition in which excess skin cells form scaly, dry patches on the body. The patches, called plaques, can have a silver or reddish color and cause itching and discomfort. The cause of psoriasis is reported to be due to an immune system defect that causes skin cells to grow ten-times faster than normal cells.
The treatment for mild to moderate cases is steroid ointments or creams such as triamcinolone (Kenalog). They decrease swelling and reduce itching. These products can cause skin irritation and thinning of skin when used over time. An oral medication called methotrexate (Trexall) may also be prescribed. It can significantly clear the skin and has side
effects like nausea and diarrhea. Additionally, injectable medications such as adalimumab (Humira) and etancercept (Enbrel) treat severe psoriasis. They help block specific parts of the immune system. These medications may cause rash or injection-site pain.
