Medication safety: spotting problems and checking OTCs

Key points

  • Always suspect medications first when you see a sudden change in confusion, memory, or balance—don't assume it's just the dementia.
  • Use a free online drug interaction checker (like Drugs.com) to catch dangerous combinations, especially with OTC drugs and supplements.
  • The safest OTC pain reliever for older adults is acetaminophen (Tylenol); avoid NSAIDs and anticholinergic sleep aids unless the doctor says otherwise.
  • Do a 'brown bag' medication review with the doctor or pharmacist at least once a year, and whenever a new symptom appears.
  • Never stop a medication abruptly without talking to the prescriber—some need to be tapered off slowly.
  • Store all medications in a cool, dry, locked place, and use a pill organizer to prevent errors.

Step-by-step

  1. 1. Gather every single medication, supplement, and OTC product your loved one takes. Include anything they take regularly or occasionally—even things like vitamins, herbal teas, or creams. Put them all in one bag or on a table. This is your starting point.

  2. 2. Look for duplicates. Check if there are two bottles of the same drug with different doses (maybe from a recent change) or if the same active ingredient appears in more than one product (for example, acetaminophen in both a pain reliever and a cold medicine). Duplicates can cause accidental overdosing and worsen cognition.

  3. 3. Check the expiration dates on every bottle. Throw away any medication that is expired or that was prescribed for a condition that has since resolved. Old medications can lose potency or break down into harmful compounds. Never mix different pills in one bottle—this is dangerous and common.

  4. 4. Use a free online drug interaction checker, such as the one at Drugs.com. Enter every medication, OTC, and supplement you found. Look for interactions that could cause confusion, dizziness, or falls. Pay special attention to anticholinergic drugs (like many sleep aids, allergy meds, and bladder control drugs) because they can worsen dementia symptoms.

  5. 5. For any OTC drug, ask yourself these four questions before giving it: (a) Is this medication really needed? (b) Is it the most appropriate choice for the person's age and health conditions? (c) Will it interact with their other medications? (d) Is the dose right for an older adult? If you're unsure about any answer, do not give it until you check with the doctor or pharmacist.

  6. 6. The safest OTC pain reliever for older adults is acetaminophen (Tylenol). Avoid NSAIDs like ibuprofen (Advil) or naproxen (Aleve) unless the doctor specifically says they are safe, as they can cause stomach bleeding and kidney problems in older adults.

  7. 7. If your loved one is taking a dementia medication like donepezil (Aricept), rivastigmine (Exelon), or memantine (Namenda), and it has been prescribed for more than six months, ask the doctor to review whether it is still needed and at the right dose. Sometimes these medications lose effectiveness or become unnecessary as the disease progresses.

  8. 8. Keep a medication log for one week. Write down the time each dose is given, any new symptoms you notice, and any missed doses. Bring this log to the next doctor's appointment. This helps the doctor see patterns and decide if a medication change is needed.

  9. 9. If you suspect a medication is causing a problem, do not stop it abruptly. Some medications, like certain antidepressants or sleep aids, need to be tapered off slowly to avoid withdrawal or rebound effects. Always discuss stopping or changing a medication with the prescriber first.

  10. 10. For the person with dementia, use a pill organizer with days of the week and times of day. This reduces the chance of double-dosing or missing a dose. If they have trouble swallowing pills, ask the pharmacist if the medication can be crushed or taken with soft food like yogurt—but always check first, because some pills must be swallowed whole.

What not to do

  • Do not assume a new symptom is just the dementia. Caregivers often write off confusion or dizziness as part of the disease, but it could be a medication side effect. Instead, always consider medications as a possible cause first, and mention any new symptoms to the doctor.

  • Do not give an OTC sleep aid without checking. Many sleep aids contain diphenhydramine (Benadryl) or doxylamine, which are anticholinergic and can worsen memory and increase fall risk. Instead, try non-drug approaches like a consistent bedtime routine, reducing caffeine, and addressing pain or discomfort.

  • Do not keep old medications in the bathroom or on the nightstand. Bathrooms are humid and hot, which can degrade medications. Nightstands are easy to grab the wrong bottle. Instead, store all medications in a cool, dry, locked cabinet—especially if the person with dementia might accidentally take extra doses.

  • Do not mix multiple pills into one bottle, even for travel. This is a common mistake that leads to confusion and accidental double-dosing. Instead, use a labeled pill organizer or keep each medication in its original bottle.

  • Do not rely only on the pharmacist or doctor to catch all interactions. Busy clinicians may not see the full picture. You are the one who sees what your loved one takes every day. Use online tools and ask questions yourself.

Practical tools

  • The 'Brown Bag' Medication Review

    Once a year (or anytime you suspect a problem), put all medications, OTCs, and supplements in a brown bag and take them to the doctor or pharmacist. Ask them to review each one for necessity, dose, interactions, and side effects. This is a simple, powerful way to catch problems.

  • Free Drug Interaction Checker (Drugs.com)

    Go to Drugs.com and use their free drug interaction checker. Enter every medication, OTC, and supplement. It will flag interactions and explain the severity. Print the results and discuss them with the doctor.

  • The Beers Criteria List

    Search online for the 'Beers Criteria for Potentially Inappropriate Medication Use in Older Adults.' This list (updated by the American Geriatrics Society) names medications that are risky for seniors. Check if any of your loved one's meds are on it. For example, many anticholinergic drugs and benzodiazepines are listed.

  • Pill Organizer with Lock

    Use a weekly pill organizer with compartments for morning, noon, evening, and bedtime. If the person with dementia might take extra pills, get a locking pill box or store the organizer in a locked drawer. This prevents accidental overdose.

  • Medication Log Template

    Create a simple chart with columns for: date, time, medication name, dose, given by, and any new symptoms. Fill it out daily. This helps you spot patterns and gives the doctor concrete data.

  • The 'Ask the Pharmacist' Script

    When you pick up a new prescription, say to the pharmacist: 'My loved one has dementia and is on [list current meds]. Can you check if this new one is safe? Are there any interactions? Is the dose right for their age and kidney function?' Pharmacists are a free, accessible resource.

Discuss with your clinician

Ask the doctor: 'Is it safe to stop any of my loved one's current medications? Which ones might be causing confusion or falls?'

Ask the pharmacist: 'Can you check if this OTC drug interacts with any of their prescription meds? Is the dose appropriate for an older adult with dementia?'

If you notice a sudden change in behavior, confusion, or balance, ask the doctor: 'Could this be a medication side effect? Should we consider a dose change or a different drug?'

Before giving any new OTC pain reliever, sleep aid, or allergy medicine, ask the doctor or pharmacist: 'Is this safe for someone with dementia? Are there better alternatives?'

If the person is on a dementia medication for more than six months, ask the doctor: 'Is this medication still necessary and effective? Should we consider stopping it?'
