Which pharmacologic option is listed as strongly against use in all forms of OA?

• A. TNFi
• B. Acetaminophen
• C. NSAIDs
• D. Topical steroids

Answer: (A)

In osteoarthritis, the main issue is degeneration and mechanical wear of the joint rather than a TNF-driven autoimmune process. Treatments focus on relieving pain and preserving function, not suppressing the immune system. Drugs that block TNF-alpha are designed for autoimmune inflammatory arthritis (like rheumatoid or psoriatic arthritis) and have not shown meaningful benefit in osteoarthritis. In fact, they come with real risks, such as serious infections and other adverse effects, which makes them inappropriate for OA across all forms.

By contrast, acetaminophen and NSAIDs are commonly used to treat OA symptoms, providing analgesia and, in the case of NSAIDs, anti-inflammatory effects. Topical steroids don’t serve as standard disease-modifying therapy for OA and aren’t routinely used to treat joint symptoms, whereas systemic or intra-articular steroids may be used in specific inflammatory flares but do not address OA as a whole. So the option that is strongly avoided for osteoarthritis in all forms is the TNF inhibitor.
