What should you know about medicine for psoriatic arthritis?

Psoriatic arthritis can cause painful, swollen joints and stiffness, including stiffness after resting or on waking. Some medicines reduce inflammation quickly, while others work more gradually to change the immune activity driving the condition. A clinician may consider joint pattern, psoriasis, eye or bowel symptoms, previous medicines and plans for pregnancy before recommending a treatment.

Treatment is usually reviewed through symptoms, movement and examination. Improvement may be gradual, and a medicine may need adjustment if symptoms remain active or side effects appear. Do not stop a prescribed medicine suddenly without advice.

Keep a record of joint pain, swelling, morning stiffness, skin flares and any medicine effects. Take prescribed treatment exactly as directed and mention over-the-counter pain medicines, supplements, infections and vaccinations to your care team. Gentle movement and an individual physiotherapy plan can support strength and joint function alongside medical treatment.

Ask how the medicine should be taken, what monitoring is needed and when a review should happen. Report new symptoms rather than changing the dose yourself.

Arrange prompt medical advice if a joint becomes newly hot, very swollen or difficult to move, or if symptoms are worsening despite treatment. Seek urgent help for severe weakness, trouble breathing, facial swelling, a serious allergic reaction, or a high fever with feeling acutely unwell. Eye pain, marked redness or light sensitivity also needs prompt assessment.

Which type of medicine fits my joint and skin symptoms? When should I expect a change? What checks or blood tests are needed? Which side effects need a same-day call? What should I do if I miss a dose or develop an infection?
