In elderly patients, what dosing principle guides opioid prescribing?

• A. Use the same dose as younger adults.
• B. Start low and go slow with careful monitoring for CNS and respiratory effects.
• C. Avoid opioids entirely in elderly.
• D. Only use non-opioid analgesics.

Answer: (B)

The main idea is that older patients are more sensitive to opioids and clear them more slowly, so starting with a small dose and increasing it gradually while watching closely for adverse effects is essential. Aging brings changes in kidney and liver function, body composition, and brain sensitivity, all of which heighten the risk of central nervous system depression (sedation, confusion, delirium) and respiratory depression from opioids. Because of this, the safest approach is to use the lowest effective dose and titrate slowly, with careful monitoring of respiration, oxygen saturation, level of alertness, and cognitive status, especially when combined with other sedating medications. This cautious strategy helps balance pain relief with safety, rather than assuming the same dosing as younger adults or avoiding opioids entirely.
