Guttate psoriasis may not be preventable. However, complications or further flare-ups may be reduced by avoiding anything that triggers a psoriasis outbreak. For example, anyone with psoriasis should try to minimize all forms of skin trauma, such as scratching or vigorous rubbing, which may lead to new psoriatic lesions on previously unaffected areas. This is known as the Koebner phenomenon.

The association between streptococcal infections and guttate psoriasis cannot be overemphasized.

• Early detection and treatment of such infections may prevent an acute flare-up of the skin disease. Samples should be obtained and cultured in patients who are susceptible to psoriasis and have a sore throat.
• Some doctors advocate early antibiotic therapy of any sore throat in individuals who are susceptible.
