However, dermatologists may be using oral steroids for psoriasis more often than treatment guidelines suggest. In 2014, Al-Dabagh et al evaluated how frequently systemic corticosteroids are prescribed for psoriasis in the United States. The researchers reported, "Despite the absence or discouragement of systemic corticosteroids in psoriasis management guidelines, systemic corticosteroids are among the most common systemic treatments used for psoriasis." They found that systemic corticosteroids were prescribed at 650,000 of 21,020,000 psoriasis visits, of which 93% were visits to dermatologists. Prednisone was the most commonly prescribed systemic corticosteroid, followed by methylprednisolone and dexamethasone. To prevent rebound flares, systemic corticosteroids were prescribed with a topical corticosteroid in 45% of the visits in patients with psoriasis as the sole diagnosis. They concluded, "The striking contrast between the guidelines for psoriasis management and actual practice suggests that there is an acute need to better understand the use of systemic corticosteroids for psoriasis."
Mild rosacea may not necessarily require treatment if the individual is not bothered by the condition. More resistant situations may require a combination approach, using several of the treatments at the same time. A combination approach may include prescription sulfa facial wash twice a day, applying an antibacterial cream morning and night, and taking an oral antibiotic for flares. A series of in-office laser, intense pulsed light, or photodynamic therapies may also be used in combination with the home regimen. It is advisable to seek a physician's care for the proper evaluation and treatment of rosacea.
