How long does anti-inflammatory medication take to work for reactive arthritis?

These medicines reduce inflammation and discomfort; they do not necessarily remove the infection or trigger that started reactive arthritis. A slower response can reflect marked joint inflammation, involvement of tendons or the lower back, or a medicine that does not suit you. Improvement may be noticed as easier movement, less night discomfort, or reduced morning stiffness rather than complete symptom disappearance.

Take the medicine exactly as prescribed and do not combine anti-inflammatory products unless a clinician has checked the plan. Gentle movement can help prevent stiffness, while pacing activity protects painful joints. Keep a brief record of swelling, mobility, stomach symptoms, and any change in pain so your clinician can judge the response. If there is little improvement after the advised trial, arrange a review rather than increasing the dose yourself.

Seek urgent medical help for a hot, very swollen joint with fever, sudden inability to use a limb, severe eye pain or light sensitivity, or new weakness. Contact your prescriber promptly for black stools, vomiting blood, facial swelling, breathing trouble, or a widespread rash after taking the medicine.

Ask which improvement should appear first, how long to try this medicine, whether your other medicines affect its safety, and what alternative treatment is appropriate if swelling remains active.
