Medication Safety for Seniors: A Plain Guide for You and Your Family

When to call 911 or Poison Help

Call 911 if someone has taken too much medicine and is hard to wake, is having trouble breathing, has a seizure, or has collapsed.
If you think someone took too much acetaminophen (Tylenol and many cold medicines), get medical help or call Poison Help at 1-800-222-1222 right away, even if they feel fine.[3]
If a new rash, blisters, or peeling skin appears while taking acetaminophen, stop it and get medical care right away.[3]

Key takeaways

Harm from medicines is common. In the U.S., medicine-related harm causes more than 1.5 million emergency room visits each year.[1]
Keep one written list of every medicine, vitamin, and supplement, and show it at every visit.[1][2]
Check active ingredients. Taking two products with the same ingredient, such as acetaminophen, is an easy way to take too much.[2][3]
Grapefruit can change how some medicines work. Ask your pharmacist about yours.[4]
Taking many medicines (polypharmacy) raises the risk of side effects and falls. Ask your doctor every year whether you still need each one.[2][5]

Why medicines get riskier with age

People 65 and older tend to take more medicines than any other age group, often because they have several health problems at once.[2] NIA says this raises the risk of side effects and other unintended problems.[2] As you age, your body may also handle a medicine differently, so a dose that worked for years may not act the same way.[2]

Some medicines can also make falls more likely. CDC lists tranquilizers, sedatives, and antidepressants, and notes that even some over-the-counter medicines can affect balance.[5] NIA adds that the more medicines you take, the more likely you are to fall.[6]

The one-page medicine list

This is the most useful thing a family can do. NIA and CDC both recommend it.[1][2] For each item, write:

The name of the medicine or supplement
How much you take and when
For prescriptions, who prescribed it and why[2]

Include over-the-counter drugs, vitamins, and herbal products, even ones you use only once in a while.[2] Keep one copy at home and one in your wallet or purse.[2] Show it to every provider, including dentists and physical therapists.[2]

To keep a wallet or fridge copy that includes allergies and emergency contacts too, use our

Daily habits that prevent mistakes

From NIA and CDC tips:[1][2]

Use a routine. Tie doses to meals or bedtime, or use a weekly pill box, a chart, or a phone reminder.
Turn on a light and put on your glasses before you take medicine.
Don't skip or halve doses to save money. Ask about a lower-cost option instead.[2] Generic drugs have the same active ingredients and are just as safe.[2] Our Medicare Part D guide explains drug cost help.
Don't share medicines, and don't take someone else's.
Don't stop a prescription on your own. Ask first, because some medicines are not safe to stop suddenly.[2]
Use one pharmacy when you can, so the pharmacist can spot a bad mix.[2]
Lock up opioid pain medicines and keep all medicines away from children and pets.[2]
Throw out expired or unused medicines safely. Ask your pharmacist how.[2]

Over-the-counter does not mean harmless

Acetaminophen

Acetaminophen is in hundreds of prescription and over-the-counter products.[3] On prescription labels it may appear as APAP or a shortened word such as "Acetaminoph."[3] FDA's rules for safe use:[3]

Use only one acetaminophen product at a time.
Never take more than the label says, even if pain or fever continues.
For adults, the total in 24 hours should not be more than 4,000 mg, unless your health care professional gives other directions.[3]
Ask before using it if you have liver disease. Three or more alcoholic drinks a day while using it can cause severe liver damage.[3]

Too much acetaminophen can cause liver failure and death.[3]

Mixing drugs

Some combinations are dangerous. NIA gives two examples: aspirin should not be taken with the blood thinner warfarin, and a sleep aid (sedative) plus an allergy pill (antihistamine) can slow your reactions and make driving unsafe.[2] Before you start anything new, including a supplement, ask your doctor or pharmacist whether it mixes safely with what you already take.[2]

Grapefruit and your medicines

FDA requires warnings on some drugs about grapefruit juice.[4] With most affected drugs, grapefruit lets more of the drug into the blood, which can cause more side effects.[4] Examples FDA lists include some statins (such as simvastatin and atorvastatin), some blood pressure drugs, some heart rhythm drugs (amiodarone), and others.[4] With a few drugs, such as the allergy medicine fexofenadine, grapefruit and some other juices make the drug work less well.[4]

Not every drug in these groups is affected, and the effect varies from person to person.[4] Seville oranges, pomelos, and tangelos may act the same way.[4] Check your medication guide or Drug Facts label, and ask your pharmacist.[4]

Too many pills? Ask about a review

Doctors use a tool called the AGS Beers Criteria to spot medicines that are usually best avoided by adults 65 and older.[7] The American Geriatrics Society updated it in 2023.[7] It is meant to support shared decisions between you and your doctor, not to replace them.[7] So don't stop a medicine because it is on a list. Bring your list and ask:

"Do I still need each of these?"
"Could any of them be making me dizzy, sleepy, or confused?"
"Is there anything I could safely reduce or stop?"[2]

Researchers call safely stopping medicines deprescribing.[2]

Questions to ask about any new medicine

NIA suggests asking:[2]

What is it for, and how will I know it's working?
What side effects should I watch for, and what should I do if I get one?
Should I take it with food? Is there anything I shouldn't eat or drink?
Is it safe to drive on it?
What if I miss a dose?

Stroke symptoms
What to do after a fall
Heat stroke in older adults (some medicines raise heat risk)

FAQ

What is the maximum acetaminophen per day? FDA says no more than 4,000 mg in 24 hours for adults, and to follow the label and your clinician's advice.[3]

Can I eat grapefruit with blood pressure medicine? It depends on the drug. Some blood pressure drugs interact with grapefruit. Ask your pharmacist.[4]

What is polypharmacy? The use of multiple drugs to treat health conditions. It's common in older adults and can raise the risk of side effects.[2]

What is the Beers list? A list from the American Geriatrics Society of medicines that are usually best avoided by adults 65 and older. Your doctor uses it as a guide.[7]
