Managing Medications for Someone with Dementia

Missed doses, double doses and risky drug combinations are common when someone has dementia; learn how caregivers can keep an accurate medicine list, set up a safe routine, spot side effects, and work with the pharmacist and doctor.

Many people with dementia take several medicines: some for memory, others for blood pressure, diabetes, pain, sleep or mood. Dementia makes it hard to remember whether a pill was taken, to read labels, or to notice side effects. Medication mistakes are common, and some can be serious. Caregivers can't be pharmacists, but a few habits make medicines much safer. This article is general information. Never start, stop or change a medicine without talking to the prescriber or a pharmacist.

Step 1: Make one complete medicine list

Write down everything the person takes, including:

• Prescription medicines
• Over-the-counter medicines (pain relievers, sleep aids, allergy and cold medicines, antacids)
• Vitamins, supplements and herbal products
• Creams, eye drops, inhalers, patches and injections

For each, note the name, dose, time of day, the reason it's taken, and who prescribed it. The National Institute on Aging offers a free Managing Medications and Supplements worksheet. Keep a copy at home, a photo on your phone, and bring it to every appointment, pharmacy visit and hospital stay (see Hospital Stays and Dementia).

Step 2: Ask the right questions

When a new medicine is prescribed, the NIA suggests asking the doctor or pharmacist:

• Why is this being used, and what change should we look for?
• What's the dose, how often, and for how long?
• What side effects are possible, and which should I report right away?
• What should we do if a dose is missed?
• Could it interact with anything else on the list?

Step 3: Set up a routine that doesn't rely on memory

• Weekly pill organizers with compartments for morning, noon, evening and bedtime make it easy to see whether a dose was taken. Some have alarms or lock until the right time.
• Pharmacy blister packs. Many pharmacies will package pills by date and time for you.
• Line medicines up with daily habits, like breakfast or brushing teeth, so they're part of the routine (see Daily Care and Routines).
• Use reminders. Phone alarms, a simple chart to check off, or a daily call if the person lives alone (see Living Alone with Dementia).
• Sync refills. Ask the pharmacy to schedule all refills for the same day each month.
• Use one pharmacy if possible, so the pharmacist can check every medicine for interactions.

Step 4: Watch closely as needs change

In early dementia, a person may manage their own pills with reminders. Over time, most need someone to set out each dose and then to hand it over and watch it being taken. Signs it's time to step in include leftover pills, running out early, confusion about which pill is which, or new symptoms that might be from missed or extra doses.

Keep medicines locked or out of reach once the person can no longer manage them safely, including medicines belonging to others in the house.

Side effects to watch for

Older adults with dementia can be especially sensitive to medicines. Tell the prescriber promptly about:

• New or worse confusion, drowsiness or agitation
• Dizziness, unsteadiness or falls (see Preventing Falls in Dementia)
• Changes in appetite, sleep, bowel or bladder habits
• Nausea, vomiting or weight loss, which can occur with memory medicines like Cholinesterase Inhibitors and Memantine

Medicines that can worsen thinking. Some commonly used drugs, especially those with strong "anticholinergic" effects, can increase confusion in older adults. The NIA names examples such as diphenhydramine (found in Benadryl and many "PM" sleep aids) and dimenhydrinate (Dramamine). The American Geriatrics Society's Beers Criteria lists medicines that are often riskier for older adults and people with dementia. Don't stop anything on your own, but ask the doctor or pharmacist whether any current medicine could be affecting memory (see Medications That Can Affect Memory).

Medicines for behavior. Drugs for agitation, anxiety, sleep or psychosis are sometimes needed, but experts recommend trying non-drug approaches first. If one is prescribed, ask about the lowest effective dose, how long it takes to work and when it will be reviewed (see Treating Behavioral Symptoms and Antipsychotics and Dementia: Risks).

When the person refuses pills or has trouble swallowing

• Stay calm and try again later. A short break and a different approach often work better than insisting.
• Explain simply: "This is your heart pill, from Dr. Patel."
• Offer choices about the drink or the order, not about whether to take it.
• Ask about other forms. A pharmacist may know whether a liquid, patch or smaller pill exists. Don't crush pills or mix them into food without asking first, because some medicines must be swallowed whole to work safely.
• If swallowing is getting harder in general, see Swallowing Problems (Dysphagia) in Dementia.

Review the whole list regularly

Ask for a full review of every medicine at least once a year, and after any hospital stay, fall or big change in health. Bring all bottles in a bag (the "brown bag review") so nothing is missed. In later stages, it's reasonable to ask whether some medicines are still helping or could be reduced. That decision belongs with the doctor, the person and the family together (see Late-Stage Dementia).

Safe storage and disposal

Store medicines in a cool, dry place, away from the bathroom. Get rid of expired or stopped medicines through pharmacy take-back kiosks or community take-back days rather than leaving them where they can be mixed up.

If you think the person took too much of a medicine or the wrong one, call Poison Control at 1-800-222-1222 (U.S.), or 911 if they are very drowsy, hard to wake, or having trouble breathing.
