Do older adults need a different dose of common medications?

✓ Accepted answer

Yes, older adults frequently require dose adjustments for common medications like blood pressure and sleep aids because the body's ability to process and eliminate drugs changes significantly with age.

• Medication Metabolism Changes: As we age, liver function declines and kidney filtration slows, meaning drugs stay in the system longer. This can lead to accidental overdose even at standard doses, causing falls or confusion.
• Beers Criteria Guidelines: The American Geriatrics Society (AGS) publishes the Beers Criteria, a list of medications considered potentially inappropriate for older adults. Sleep aids, specifically benzodiazepines, are often flagged for increased risk of falls and cognitive decline in patients over 65.
• Start Low, Go Slow: Doctors generally recommend starting at the lowest effective dose for new prescriptions. If your mother has not seen a physician in several years, her current prescriptions may simply be outdated and require a fresh evaluation.
• Polypharmacy Risks: Taking multiple medications increases the likelihood of drug interactions. A comprehensive medication review can identify unnecessary drugs or dangerous combinations, such as taking a sedating sleep medication alongside certain blood pressure drugs that lower blood pressure too much when standing up.
• Consultation Action Items: Ask your mother's doctor to review her current doses against her actual weight, kidney function, and liver health. Specifically, ask if her blood pressure is dipping too low at night, which could explain the need for the sleep medication, and whether a non-sedating alternative might work better.

Scheduling a dedicated appointment for a medication review is the safest step to ensure her regimen remains effective and safe.
