When someone is diagnosed with dementia, medication often becomes part of their care plan. But families frequently don’t know what questions to ask their doctor about these medications—or they accept prescriptions without understanding what each drug does, what side effects to watch for, or whether alternatives exist. The medications prescribed for dementia and related conditions can slow cognitive decline, manage behavioral symptoms, or treat underlying conditions like high blood pressure that affect brain health, but they also carry risks that deserve careful examination. Families should ask their doctor about the specific purpose of each medication, what improvement or change they should expect to see, and what happens if a medication isn’t working as intended. Consider the case of Margaret, whose mother was prescribed both a dementia medication and a sleeping pill after a diagnosis of Alzheimer’s disease.
When Margaret’s mother began falling frequently and became confused about time of day, Margaret assumed these were symptoms of advancing dementia. It wasn’t until a pharmacist reviewed her mother’s medications that they discovered the combination of drugs was making her drowsy and disoriented. By asking clarifying questions—what each medication was meant to do, whether the side effects matched the benefits, and whether doses could be adjusted—Margaret’s family was able to work with the doctor to change the approach. The falls decreased, and her mother’s mental clarity improved. This scenario illustrates why understanding medications, asking the right questions, and staying engaged in the medication review process can genuinely affect quality of life.

What Should You Ask About Each Medication Your Loved One Takes?
The starting point for a medication review is understanding the purpose of each drug. Ask your doctor: “What is this medication supposed to do?” and “How will we know if it’s working?” Many families discover their loved one is taking multiple medications, and no one clearly explained what each one addresses. For someone with dementia, medications might target cognitive symptoms (like a cholinesterase inhibitor such as donepezil), behavioral issues (like an antidepressant or antipsychotic), or coexisting conditions (like a statin for cholesterol). When you know the specific intention, you can observe whether the medication is delivering on that goal.
Follow up by asking about the expected timeline. Some medications take weeks or months to show benefits, while others work immediately. Ask: “How long should we give this medication before deciding if it’s helping?” and “What changes should we expect to see?” A medication that hasn’t shown improvement after the expected trial period may need to be discontinued or adjusted. Also ask about monitoring: “What side effects should I watch for?” and “How often will we check in to see if this is still the right choice?” This last question is critical because dementia is progressive, and a medication that was helpful six months ago may no longer be needed—or the dose may need adjustment as the person’s weight, kidney function, or overall health changes.
How Can You Identify Problematic Medication Combinations or Doses?
One of the most dangerous aspects of dementia care is the potential for medication overload. Older adults with dementia often see multiple doctors—a primary care physician, a neurologist, a cardiologist—and each may prescribe medications without knowing the full picture of what other drugs the person is taking. This can lead to drug interactions, duplicate therapies, or doses that are too high for someone whose metabolism is slowing with age. A limitation of relying solely on individual doctors is that each one may have incomplete information about the total medication burden. Ask for a complete medication review from a geriatrician or clinical pharmacist.
Many insurance plans cover this service, and it can be life-changing. During this review, a pharmacist will examine every medication—including over-the-counter drugs, supplements, and topical creams—to identify interactions, duplicates, or medications that may be harming rather than helping. For instance, a common warning sign is when someone with dementia is taking both a cholinesterase inhibitor and an anticholinergic medication (like a drug for urinary incontinence or certain antidepressants). These two drug classes work against each other, and the anticholinergic can actually worsen cognitive symptoms. A professional medication review can catch this and suggest alternatives.
What About Medications for Behavioral and Mood Changes?
Behavioral symptoms like agitation, aggression, or wandering are common in dementia, and they’re often treated with antipsychotic medications. However, families should know that antipsychotics carry significant risks, especially in older adults. Ask your doctor: “Is an antipsychotic the right first step, or should we try non-drug approaches first?” Research shows that behavior changes often improve when underlying issues are addressed: pain, urinary tract infections, constipation, hunger, boredom, or changes in routine can all trigger behavioral outbursts in someone with dementia. Before accepting an antipsychotic prescription, ask whether the doctor has ruled out medical causes for the behavior.
Then ask: “What non-medication strategies have been tried?” This might include structured activities, music therapy, changes to the environment, or adjustments to care routines. If medication is still recommended after these approaches, ask about the dose, the target behaviors, and the timeline for reassessment. Antipsychotics can cause stroke, falls, and heart problems, particularly in people with dementia, so the benefit needs to clearly outweigh these risks. Also ask: “How long will my loved one need to be on this medication?” and “What would stopping this medication look like?” The goal should be to use the lowest effective dose for the shortest necessary time, not as a permanent solution.
How Do You Manage Medication Changes Over Time?
Dementia is progressive, and the medication needs of someone in early stages look very different from those in later stages. Early on, the focus might be on slowing cognitive decline, but as the disease progresses, the priorities shift to comfort, managing behavioral symptoms, and treating coexisting conditions. Ask your doctor: “As dementia progresses, how will my loved one’s medications need to change?” and “Are we planning to continue all of these medications indefinitely, or will we reassess?” A tradeoff families often face is between trying to slow disease progression and avoiding medication overload. Someone in advanced dementia may not benefit from a cholinesterase inhibitor, since these drugs work best in mild to moderate stages. At that point, continuing the medication may cause side effects without benefit.
This is where a conversation about goals of care becomes essential. Ask: “What is the goal of treatment at this stage—prolonging life, maintaining quality of life, managing symptoms, or comfort?” Different goals lead to different medication decisions. Some families choose to simplify medications as dementia advances, focusing only on drugs that address immediate comfort or suffering. Others prefer to continue disease-modifying medications as long as possible. Neither choice is “right,” but making it deliberately, based on clear communication with your medical team, leads to better care.
What About the Risks of Medication for Older Adults with Dementia?
Older adults, particularly those with dementia, are at higher risk for medication side effects because their bodies metabolize drugs differently, they’re more sensitive to certain drug classes, and they may not report side effects clearly. Benzodiazepines, anticholinergics, opioids, and nonsteroidal anti-inflammatory drugs (NSAIDs) are examples of medication classes that carry extra warnings in older adults. A critical warning is that many medications increase fall risk—antipsychotics, sedatives, blood pressure medications, and even some pain relievers can cause dizziness, weakness, or confusion that leads to falls. Falls are a leading cause of injury and hospitalization in people with dementia.
Ask your doctor: “Does this medication increase fall risk?” and “What can we do to reduce that risk?” Sometimes the answer is a lower dose, sometimes it’s closer monitoring, and sometimes it’s choosing a different medication. Also ask about memory and cognitive effects: some medications can worsen confusion or memory problems in people with dementia, even though they’re prescribed for other conditions. Request a review of your loved one’s medications against a geriatric prescribing guideline called the Beers Criteria, which lists medications that are generally inappropriate for older adults. Your pharmacist can also help identify medications on this list. If your loved one is taking a medication flagged as potentially inappropriate, ask: “Is there a safer alternative?” Sometimes there is, and sometimes the benefit of the medication outweighs the risk—but you should make that decision knowingly.
How Do You Keep Track of Complex Medication Schedules?
Someone with dementia taking multiple medications needs a system to ensure doses aren’t missed or duplicated. Ask your pharmacy about pill organizers with alarms, blister packs that are labeled by date and time, or delivery services that provide pre-sorted doses. If your loved one is managing their own medications, watch for confusion about what to take when. If you or a caregiver is managing them, consider a medication log that records what was taken, when, and any observed effects or side effects.
This is also where a conversation with the pharmacist—not just the doctor—becomes valuable. Pharmacists often have more time to discuss side effects, drug interactions, and practical questions about taking medications. Ask: “Can any of these medications be combined to reduce the number of doses?” and “Are there times when these medications work better together or separately?” Sometimes adjusting the timing of doses can reduce side effects or improve effectiveness. A simple example is taking a medication with food if it causes nausea, or separating two medications by a few hours if one interferes with the absorption of the other. These practical adjustments often come from a pharmacist’s expertise.
Looking Forward—When to Reconsider the Medication Plan
As dementia advances, some medications become less relevant to goals of care, and the focus naturally shifts to comfort and quality of life. Some families and doctors choose deprescribing—intentionally reducing or stopping medications that are no longer serving the person’s values or goals. Ask your doctor: “If my loved one’s condition changes, or if they express that they don’t want a particular medication, can we revisit these prescriptions?” This is especially important for preventive medications like statins (for heart disease prevention) or blood pressure medications, which may be less relevant in advanced dementia where the focus is on comfort rather than lifespan extension. Ultimately, the best approach is one built on ongoing conversation.
Medication review isn’t a one-time event but a regular touchstone in your loved one’s care. Aim to have a comprehensive medication review at least annually, or whenever there’s a significant change in your loved one’s condition, when new symptoms appear, or if you notice side effects that concern you. Bring written questions to appointments, take notes on the answers, and follow up if something doesn’t feel right. Your role as an advocate—asking questions, staying informed, and ensuring your loved one’s medications are working toward their goals—is one of the most meaningful contributions you can make to their care.
Conclusion
Asking the right questions about dementia medications protects your loved one from unnecessary harm and ensures that every drug in their regimen is serving a genuine purpose. By understanding what each medication does, recognizing potential side effects, addressing drug interactions, and reassessing regularly as needs change, families can optimize treatment outcomes and quality of life. The goal isn’t necessarily to use fewer medications—sometimes medications are genuinely needed and beneficial—but to use the right medications at the right doses for the right reasons.
Start with your doctor and pharmacist, ask for a comprehensive medication review if your loved one is taking multiple drugs, and commit to regular check-ins as circumstances evolve. Dementia care is a partnership, and your informed participation in medication decisions is essential. If you’ve noticed side effects, concerns about drug interactions, or questions about whether a medication is still appropriate, bring these up at your next appointment. Your observations and questions are data your doctor needs to provide the best care.
