How is psoriasis treated?

What guides treatment choice?

Choice depends on more than surface area. Clinicians consider psoriasis type and location, itch or pain, nails and joints, impact on life, age, pregnancy or plans for pregnancy, other health conditions, current medicines, and results of previous treatments.

Agree on goals and review them, such as sleeping better, using the hands or walking more comfortably, reducing disease in high-impact areas, and following a realistic plan. If results are insufficient or adverse effects occur, ask for an adjustment rather than increasing, reducing, or combining medicines yourself.

Who may use topical treatment?

Topical treatment is important, particularly when psoriasis affects a limited area, and it may be combined with other approaches for more extensive disease. The medicine, strength, formulation, amount, duration, and body area must be appropriate.

Treatment for the scalp, nails, face, folds, or genitals may differ from treatment for the elbows or knees. Follow instructions about amount and treatment breaks, and report irritation, skin thinning, or a change in symptoms.

How is phototherapy different from sun exposure?

Medical phototherapy uses a defined type and dose of ultraviolet light with a treatment schedule and monitoring. It is not the same as sunbathing or a tanning bed, where the dose is uncontrolled and may cause burns or additional ultraviolet damage.

A clinician may consider phototherapy when topical treatment is insufficient, disease is widespread, or the pattern and location are suitable. Frequency, duration, other treatment, and previous ultraviolet exposure are part of safety assessment.

When are oral or injected medicines considered?

Systemic medicines may be considered for moderate or severe disease, when local treatment is insufficient, for high-impact sites, or when psoriatic arthritis is present. Options include conventional systemic, targeted, and biologic medicines, but none is appropriate for everyone.

Selection considers expected benefit, risk, other conditions, infection, pregnancy or pregnancy plans, vaccines, other medicines, and follow-up. Some options require blood tests or screening before and during treatment. Targeted or biologic treatment should be started and supervised by an experienced clinician.

Why is follow-up part of treatment?

Follow-up checks changes in lesions, symptoms, nails, joints, and quality of life, while looking for adverse effects and relevant associated conditions. Bring your medicine list, test results, new symptoms, and any difficulty following the plan.

If psoriasis settles, do not stop or change treatment alone. Ask about maintenance, what to do during a flare, and when to be reviewed. Tell the care team before changes if you are pregnant, planning pregnancy, breastfeeding, have an infection, or expect a vaccination.

Can psoriasis be cured?

Psoriasis is a chronic condition that can improve and flare, and there is currently no cure. Treatment aims to control symptoms and impact. Be cautious of cure promises or guaranteed treatment withdrawal; responses and timing vary between people.
