Acetaminophen is indicated for OA under what guideline?

• A. Always first-line for all forms
• B. Not indicated for OA
• C. Conditional for all forms
• D. Only for knee OA

Answer: (C)

Acetaminophen is treated as a conditional option for OA analgesia across different joints. This reflects that its benefit tends to be modest and its use depends on individual factors—such as liver function, age, comorbidities, and NSAID safety concerns—so guidelines don’t mandate it for every patient or for every OA form. It can be a reasonable initial choice in some people, especially when NSAIDs are unsuitable, but it isn’t universally first-line for all OA and all joints. It isn’t limited only to knee OA, and it isn’t correct to say it’s not indicated at all.
