When is anti-inflammatory medication recommended for knee osteoarthritis?

Knee osteoarthritis can irritate tissues around a worn joint, causing aching, stiffness, or swelling. Anti-inflammatory medicines can reduce inflammation and make walking or exercise more manageable; they do not rebuild cartilage or reverse the joint changes. A clinician may consider a topical product for pain near the skin, or an oral medicine when symptoms are more troublesome. The safest option depends on stomach, kidney, heart, and blood-pressure health, as well as pregnancy, allergies, and medicines such as blood thinners.

Use the smallest effective amount for the shortest suitable period, following the label or prescription. Do not combine different anti-inflammatory products unless a clinician specifically tells you to. Keep gentle movement, strengthening, weight-management support when relevant, and pacing as part of care; medicine works best as one part of that plan. Stop and seek advice if you develop severe stomach pain, vomiting blood, black stools, facial swelling, wheezing, or a marked drop in urine.

Arrange an assessment if knee pain is new, worsening, or preventing ordinary activities. Seek urgent care for a hot, red, very swollen knee with fever, sudden inability to bear weight, or a knee that looks deformed after an injury. These features can point to infection, a significant injury, or another problem that anti-inflammatory medicine alone should not mask.

Ask which type is suitable, whether a topical option is enough, how long to try it, and which warning symptoms matter for you. Mention ulcers, kidney or heart disease, high blood pressure, asthma triggered by painkillers, pregnancy, and every prescription, over-the-counter medicine, and supplement you use.
