Which is considered first-line pharmacologic therapy for mild to moderate osteoarthritis in an older patient with bleeding risk?

• A. Nonsteroidal anti-inflammatory drugs
• B. Intraarticular corticosteroid injections
• C. Acetaminophen
• D. Disease-modifying antirheumatic drugs

Answer: (C)

Acetaminophen is the best first-line pharmacologic choice for mild to moderate osteoarthritis in an older patient with bleeding risk. It provides analgesia without the GI bleeding, ulceration, and other bleeding-related concerns that come with NSAIDs, making it safer for someone at higher risk of GI injury. It does not have the same antiplatelet effects or broad gastrointestinal toxicity as NSAIDs, and while it lacks anti-inflammatory action, it often provides adequate pain relief for many patients with mild to moderate OA when used at the recommended dose. Safety notes: keep total daily acetaminophen within about 3 to 4 grams for adults, and adjust for liver disease or alcohol use to avoid hepatotoxicity. If acetaminophen alone is insufficient, nonpharmacologic measures should accompany therapy, and other options such as topical NSAIDs or intra-articular corticosteroid injections can be considered for additional relief. Disease-modifying antirheumatic drugs are not used for OA, as they target inflammatory arthritis rather than degenerative joint disease.
