Psoriasis patients prefer oral treatments and are more adherent to orals than to topicals, but adherence to oral treatment of psoriasis may still be limited, compromising treatment outcomes. How well the medication works in the patients who take treatment regularly is not well characterized.
Most people with psoriasis have very limited disease, yet that disease may still have a large impact on their lives. While limited psoriasis may be amenable to topical treatment, patients are exceptionally poorly adherent to topical treatment, especially over the long run.
