How long does anti-inflammatory medication take to work for ankylosing spondylitis?

These medicines reduce inflammation and can make morning stiffness, back pain, or discomfort around the joints easier to manage. They do not change the underlying condition immediately, and a partial response can still be useful information for your clinician. Ankylosing spondylitis symptoms may fluctuate, so judge the effect by your movement and stiffness over several days rather than one dose alone.

Take the medicine exactly as prescribed and do not add another anti-inflammatory product without checking first. Keep a short record of dose timing, morning stiffness, pain, mobility, and stomach symptoms. Gentle movement, posture work, and the exercise plan advised by your physiotherapist can support symptom control. If the prescribed trial does not provide enough relief, your clinician can review the dose, medicine choice, and other treatment options.

Contact your clinician if symptoms remain limiting despite taking the medicine as directed, or if pain and stiffness steadily worsen. Seek urgent help for vomiting blood, black stools, facial swelling, trouble breathing, severe chest pain, new loss of bladder or bowel control, or rapidly developing weakness.

Ask how long your planned trial should last, what improvement to track, whether the medicine is suitable with your stomach, kidney, heart, or blood-pressure history, and what the next step is if stiffness remains prominent.
