Your mother sees a cardiologist, a kidney doctor, a rheumatologist and her primary care doctor. Each added a prescription or two. She also takes a sleep aid, an antacid and three supplements a friend recommended. Lately she's been foggy in the afternoons and fell in the kitchen last week. Nobody has looked at the whole list in years.
That's polypharmacy, and it's one of the most fixable causes of confusion, dizziness and falls in older adults. This guide explains what families can do. It's general information; never change a medicine without talking to the prescriber.
What polypharmacy is
Polypharmacy usually means taking five or more medicines regularly, though the exact number matters less than whether each one is still needed and safe together. Older adults often have several chronic conditions, such as high blood pressure, diabetes, arthritis and heart disease, each treated with its own medicines. Add specialists who don't always talk to each other, over-the-counter remedies and supplements, and the list grows quickly.
Many of those medicines are helpful. The problem is when nobody steps back to ask whether all of them are still the right choice, at the right dose, for this person at this stage of life. Eye drops count as medicines too; see glaucoma in the elderly.
Why it's risky for older adults
MedlinePlus lists several risks of taking multiple medicines: a greater chance of side effects, a higher risk of drug interactions, and a higher risk of falls with certain medicines1. Aging bodies also process drugs differently. The kidneys and liver clear medicines more slowly, so doses that were fine at 60 can build up at 80. Older adults may be more sensitive to drugs that act on the brain.
- Falls. Sleep aids, some anxiety and pain medicines, blood pressure drugs and others can cause dizziness or unsteadiness. See fall prevention.
- Confusion. Some medicines can cause or worsen confusion and even delirium, which can look like dementia.
- Interactions. One drug can boost or block another, or two can add up to too strong an effect, as with blood thinners and some pain relievers.
- Prescribing cascades. A side effect is mistaken for a new condition and treated with yet another drug.
- Mistakes. Complicated schedules make missed or doubled doses more likely3.
Warning signs to watch for
Medication problems often look like aging or a new illness. Ask about medicines when you notice:
- New confusion, forgetfulness or drowsiness, especially after a medicine change.
- Dizziness, unsteadiness or falls.
- Loss of appetite, nausea or constipation. See constipation in older adults.
- Changes in mood or behavior, like agitation or withdrawal.
- Trouble urinating or new incontinence.
- Bruising or bleeding in someone on blood thinners.
- Pills left over or running out early, which suggest doses are being missed or doubled.
If a change is sudden or severe, such as new confusion over a day or two, call the doctor promptly. Sudden confusion can signal an infection or other urgent problem as well as a medicine reaction.
Start with a complete medicine list
MedlinePlus recommends keeping a list of all medicines, including prescription and over-the-counter drugs, keeping copies in a wallet and at home, and reviewing it with providers and pharmacists at every appointment1. A good list includes:
- The name and dose of each medicine.
- How and when it's taken, for example, one tablet twice a day with food.
- Why it's taken and who prescribed it.
- Over-the-counter medicines, like pain relievers, sleep aids, antacids and allergy pills.
- Vitamins, herbal products and supplements.
- Allergies and past reactions.
A practical way to build it is the brown bag check: put every bottle in the house, including old ones and anything in the bathroom cabinet, in a bag and bring it to the doctor or pharmacist. Then remove expired and discontinued medicines from the house so they can't be taken by mistake.
Ask for a full medication review
Once a year, and after any hospital stay, ask your parent's primary care doctor or a pharmacist to review the whole list. Good questions include: Is each medicine still needed? Is the dose right for my parent's age and kidney function? Do any of these interact? Could any be causing the dizziness, confusion or constipation we're seeing? Is there a simpler schedule? Are any medicines on lists of drugs that are often risky for older adults?
If your parent has a Medicare drug plan and takes medicines for more than one chronic condition, they may qualify for Medication Therapy Management, which is free for those who qualify2. It usually includes a comprehensive review with a pharmacist or provider, a written summary, a recommended to-do list and a medication list2. Call the plan to ask about eligibility. Medicare drug plans and pharmacists also run safety checks for interactions and unsafe opioid amounts before filling prescriptions2.
Stopping medicines safely
Reducing or stopping medicines that no longer help, sometimes called deprescribing, can improve how a person feels. Some medicines can be stopped at once; others, like some sleep aids, anxiety medicines, antidepressants, steroids and blood pressure drugs, need to be tapered slowly to avoid withdrawal or rebound effects. That's why changes should always go through the prescriber. Ask for one change at a time so you can tell what made a difference.
Goals may also change with time. For a parent in late-stage illness, medicines aimed at preventing problems years from now, like some cholesterol drugs, may matter less than comfort. That's a conversation to have with the doctor, and with hospice or palliative care if involved. See hospice vs. palliative care.
Making the routine easier
- Use one pharmacy so the pharmacist can spot interactions across all prescriptions.
- Ask about blister packs or pre-sorted packets by time of day.
- Use a weekly pill organizer filled by you or a nurse, and set phone or speaker reminders.
- Line up refills so they're due on the same day each month.
- Ask whether doses can be combined or simplified, such as once-daily versions.
- Keep a simple chart that says what to take, when, and what it's for.
If your parent has memory problems, supervision may be needed. Home care aides can give reminders, and assisted living communities manage medicines in different ways; see medication management in assisted living.
Hospital stays and transitions
Medication errors often happen when a parent moves between settings: hospital to rehab, rehab to home. Medicines may be stopped, started or changed, and the old bottles at home may no longer match. Bring the medicine list to the hospital, and before discharge ask for an updated list that says clearly which medicines to stop, start or change2. Then go through the bottles at home with the new list. Our guide to hospital discharge planning explains what else to ask.
Over-the-counter medicines and supplements
Families often overlook what's bought without a prescription. Common sleep aids and allergy pills contain antihistamines that can cause confusion and constipation in older adults. Pain relievers like ibuprofen and naproxen can raise blood pressure and harm the kidneys. Antacids can interfere with absorption of other medicines. Herbal products and supplements can interact with blood thinners and other drugs. Ask the pharmacist before your parent starts anything new, and include these on the medicine list1.
Talking with your parent and the doctors
Some parents feel protective of their medicines or worry that stopping one will make them sick. Others want fewer pills but don't want to question the doctor. Offer to help prepare questions and go to the appointment. Frame it as safety and feeling better: "I want to make sure none of these is causing the dizziness." If several specialists are involved, ask the primary care doctor to coordinate. If your parent has a health care proxy, that person can help speak up when your parent can't.
When medicines become too much to manage
If your parent can't manage medicines safely alone, even with organizers and reminders, it may be time for more help. Options include a visiting nurse, home care aides who give reminders, or a move to a setting where staff handle medicines. Our guide to signs it's time for senior living can help you decide.
Medicines and memory
Families of people with memory loss should be especially alert. Some common medicines, including certain bladder, allergy, sleep and stomach drugs, have effects that can worsen thinking in older adults. Before assuming a parent's memory is simply declining, ask the doctor whether any medicine could be contributing. On the other hand, people with dementia may forget doses or take extra, so supervision matters. Our guides to mild cognitive impairment and Alzheimer's medications explain what to ask. A pharmacist can also suggest which medicines to give at which times so that the daily routine is simpler for both of you, and whether any liquid or patch forms would make things easier if swallowing pills is hard.
An example
After her mother's fall, Kim did a brown bag check and found 14 medicines, including two sleep aids, an old muscle relaxant and an antihistamine taken every night. The pharmacist and doctor stopped three and tapered a fourth. Her mother's afternoon fog lifted, and she hasn't fallen since. Kim now keeps an updated list on her phone and her mother's refrigerator. This is an illustration; changes must be made with the prescriber.
