Biologics are medicines similar to or the same as proteins made by the body. These medicines, such as alefacept and etanercept, block the harmful response of the body's immune system that causes the symptoms of psoriasis.

Biologics are used mainly for people who cannot use other treatments or whose psoriasis did not improve with other types of therapy. Although biologics may not be more effective than other treatments for psoriasis, they may be safer for organs, such as the liver or kidneys, that some oral medicines can damage. But the long-term safety of biologics is not known.

What To Think About

You may need to try different treatments before you find one that works well for you. It is important to discuss your treatment and progress with your doctor.

One study found that education, stress reduction, and muscle relaxation training can help many people who have psoriasis. Adding these elements to a treatment plan can reduce disability, anxiety, and stress related to dealing with psoriasis.³

Treatments for psoriasis have potential side effects. People with moderate or severe psoriasis may need treatment for the rest of their lives. Many doctors will recommend that treatments be changed or rotated after a certain period of time to make treatment more effective and to reduce side effects.
