What is a safe analgesic choice for elderly patients and what is the recommended daily maximum dose?

• A. Acetaminophen; maximum 3-4 g/day (2-3 g if risk factors or older adults); caution in liver impairment.
• B. Ibuprofen; maximum 1 g/day.
• C. Morphine; maximum 10 mg/day.
• D. Aspirin; maximum 1 g/day.

Answer: (A)

Choosing an analgesic for older adults centers on balancing effective pain relief with the lowest risk of harm. Acetaminophen is favored because it provides reliable pain control without the major gastrointestinal, renal, or cognitive risks seen with NSAIDs or opioids in the elderly. It has no significant impact on platelet function, and it lacks the sedative and delirium risks associated with many opioids, making it safer for routine use in many older patients.

A practical safety guideline is to keep total daily acetaminophen within a conservative limit to avoid hepatotoxicity. The common upper limit for most adults is about 4 grams per day, but in older individuals or those with risk factors such as chronic alcohol use or preexisting liver disease, the limit should be reduced to 3 grams per day or less. If there is any liver impairment, use requires further caution and often lower dosing, with careful review of all acetaminophen-containing products to prevent accidental overdose.
