Which statement about non-opioid analgesics is true?

• A. For severe pain only
• B. For mild pain only
• C. For acute and persistent moderate pain; examples acetaminophen and NSAIDs
• D. They are only used topically

Answer: (C)

Non-opioid analgesics are best thought of as appropriate first-line options for many types of pain that are not severe. They include acetaminophen and NSAIDs, and they work in different ways to reduce pain and, for NSAIDs, inflammation. This makes them suitable for acute pains like a sprain or postoperative discomfort, and also for persistent moderate pain such as chronic arthritis, where ongoing but not severe pain is present. They’re not reserved for mild pain only, and they’re not used exclusively on the skin; most non-opioids are taken systemically (orally, or by other routes) rather than only applied topically.

Acetaminophen helps relieve pain and fever mainly through central mechanisms, while NSAIDs like ibuprofen or naproxen block prostaglandin synthesis, reducing both pain and inflammation. Because they can handle moderate pain and have anti-inflammatory effects (in the case of NSAIDs), they’re often used as a stepping-stone in pain management before considering opioid therapy. It’s important to use them within recommended dosing to minimize risks: NSAIDs can irritate the stomach and affect kidneys, and acetaminophen can harm the liver at high doses or with heavy alcohol use.

So the statement that captures their role—effective for acute and persistent moderate pain with examples such as acetaminophen and NSAIDs—best reflects how non-opioid analgesics are used.
