A patient with suspected renal colic asks about pain management. Which pharmacologic approach is commonly appropriate first-line?

• A. Antibiotics for pain control
• B. NSAIDs or opioids for acute pain control, with aggressive hydration
• C. Surgery
• D. Antidepressants

Answer: (B)

Pain from renal colic is managed most effectively first with rapid analgesia using NSAIDs or opioids, along with ensuring adequate hydration. NSAIDs are usually preferred because they target the inflammatory and prostaglandin-driven processes that heighten ureteral spasm and renal pelvic pressure, providing quick and often potent relief. They help reduce pain and relax the ureter by lowering prostaglandin synthesis. If NSAIDs can’t be used or don’t provide enough relief, opioids are a strong alternative for acute pain control. Hydration supports urine flow, which can aid stone passage and dilute the urine, though it’s important to avoid overhydration in patients with certain conditions. Antibiotics are reserved for infections, not routine pain management, and surgery or other chronic medications aren’t first-line for acute analgesia.
