What are the treatment options for guttate psoriasis?

Guttate psoriasis causes many small, drop-shaped scaly patches, often across the trunk and limbs. A clinician considers the amount of skin involved, itch, scale, previous episodes, and whether joint symptoms are present. A recent throat or other infection may also be relevant to the assessment, but antibiotics are not a treatment for the psoriasis itself unless an infection is diagnosed.

For limited areas, a prescribed cream or ointment may reduce inflammation and scaling. Learn safe application from your clinician and avoid using strong steroids on the face or skin folds unless specifically directed. [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) are one option to discuss. When patches cover broader areas or do not settle, [Narrowband UVB Phototherapy](/treatments/medical-dermatology/narrowband-uvb-phototherapy/) may be considered through a supervised course. Gentle bathing, regular moisturiser, and avoiding skin injury can reduce irritation.

Book a review if the rash is widespread, worsening, or interfering with sleep. Seek urgent advice for a rapidly reddening or painful rash, fever, feeling very unwell, pus-filled spots, or new swollen and painful joints. These features need assessment rather than self-treatment.

How extensive is my psoriasis, and which treatment should I start with? Would light therapy be suitable for my skin and schedule? Could a recent infection or joint symptom change the assessment?
