Psychiatric Medications for Older AdultsManaging Multiple Medications Safely

Many older adults take medications for blood pressure, diabetes, pain, sleep, and mood, sometimes prescribed by several different doctors. Psychiatric medications for older adults can help a great deal, but they need extra care. Aging changes how the body absorbs, processes, and clears drugs, and side effects like dizziness or confusion can have serious consequences. This guide explains why, what the Beers Criteria are, how interactions happen, and how family members can help keep things safe.

Why Psychiatric Medications for Older Adults Need Extra Care

Psychiatric medications for older adults need extra care because aging slows how the liver and kidneys clear many drugs, increases sensitivity to side effects, and often comes with multiple medications and health conditions that raise the risk of interactions. A dose that’s well tolerated at 40 may cause sleepiness, falls, or confusion at 80.

According to the American Geriatrics Society, one in six adults age 65 or older will have at least one side effect from their medicines. That’s why reviewing every medication regularly matters so much in later life.

What Are the Beers Criteria?

The Beers Criteria are an evidence-based list, maintained by the American Geriatrics Society, of medications that may carry more risks than benefits for adults 65 and older and are often best avoided or used with caution. The 2023 AGS Beers Criteria update was based on a review of more than 1,500 studies and includes over three dozen medications or classes to avoid for most older people, plus more than 40 to use with caution or avoid with certain conditions.

Several psychiatric medications appear on the list, including benzodiazepines, some sleep medications, and medications with strong anticholinergic effects, which can cause confusion, constipation, and falls. The criteria are meant to guide, not replace, shared decision-making, so a medication on the list may still be the right choice in some situations.

In older adults, the right dose is often lower, the right list is often shorter, and every new symptom deserves a medication check.

Drug Interactions in Older Adults

Drug interactions in older adults happen when medications change each other’s levels or add up in their effects, such as combined sedation, low blood pressure, or bleeding risk, and they become more likely as the number of medications grows. Over-the-counter drugs and supplements can interact too.

• Additive sedation: combining sleep aids, pain medications, and some psychiatric drugs can raise fall risk.
• Anticholinergic load: several medications with anticholinergic effects can add up to confusion or memory problems.
• Sodium changes: some antidepressants can lower sodium levels, especially in older adults.
• Bleeding risk: some antidepressants combined with blood thinners or pain relievers can raise bleeding risk.

Medication Dosing for Seniors

Medication dosing for seniors usually follows the principle of “start low and go slow,” beginning with lower doses and increasing gradually, because older adults often need less medication and are more sensitive to side effects. Doses may also need adjusting when kidney or liver function changes.

1. Start low. Begin with a lower dose than would be used in younger adults.
2. Go slow. Increase gradually, watching for side effects at each step.
3. Check the whole list. Review every prescription, over-the-counter drug, and supplement for interactions.
4. Watch for new symptoms. Report confusion, falls, dizziness, or unusual sleepiness right away.
5. Reassess regularly. Review whether each medication is still needed at least once a year.

Depression and anxiety in later life are still worth treating. NIMH data show that 4.5% of U.S. adults 50 and older had a major depressive episode in 2021, and depression in older adults is often mistaken for normal aging. Our article on late-life depression covers the signs.

Helping a Parent Manage Medications

Helping a parent manage medications starts with keeping one complete, current list, attending appointments when possible, and watching for changes in thinking, balance, sleep, or mood after a new medication or dose change. Adult children and caregivers are often the first to notice problems.

Practical tools help: pill organizers, pharmacy blister packs, a single pharmacy for all prescriptions, and a written schedule. Bring the actual pill bottles, including supplements and over-the-counter medications, to a medication review. With your parent’s permission, a psychiatrist can include you in visits and explain the plan.

When to Ask for a Medication Review

Ask for a medication review when an older adult takes several psychiatric or sedating medications, has new confusion, falls, dizziness, or sleepiness, or hasn’t had their full medication list reviewed in the past year. New symptoms in older adults should always prompt a medication check.

A comprehensive psychiatric evaluation with Dr. Farkas can review every medication, coordinate with primary care, and plan any changes carefully.
