Causes    Return to top

Guttate psoriasis is a relatively uncommon form of psoriasis. It is usually seen in patients younger than 30. The condition often develops very suddenly, usually after an infection, most notably strep throat. Guttate psoriasis is not contagious.

Persons with very severe guttate psoriasis may receive medicines to suppress the body's immune response. These medicines include corticosteroids, cyclosporine, and methotrexate.

Sunlight may help your symptoms go away. Be careful not to get sunburn. Some people may choose to have phototherapy. Phototherapy is a medical procedure in which your skin is carefully exposed to ultraviolet light. Phototherapy may be given alone or after you take a drug that makes the skin sensitive to light.
