Shared Decision-Making About Antipsychotics for Dementia: A Guide for Caregivers and Families

Deciding whether to use antipsychotic medication for a loved one with dementia is one of the hardest choices you will face. This article walks you through a collaborative process that puts your family member's comfort and safety first. You will learn how to have a full, informed conversation with the clinical team, weigh the real benefits against serious risks, and ensure every decision is documented and revisited regularly. There are concrete steps you can take to feel empowered, not overwhelmed, in this journey.

Key points

  • Shared decision-making means you, your loved one, and the clinician work as a team to weigh risks and benefits, using a structured tool like the NICE decision aid.
  • Antipsychotics carry a black box warning for increased mortality in dementia—this must be discussed and documented before starting.
  • Always rule out physical causes (pain, infection, delirium) and try non-drug strategies first.
  • If an antipsychotic is started, use the lowest effective dose for the shortest time, with a clear target symptom and a plan for gradual dose reduction.
  • Document every step of the conversation, including the risks discussed and the decision made, to protect everyone and ensure accountability.
  • Personalize the approach based on the type of dementia, stage of illness, caregiver role, and living situation.

Why Shared Decision-Making Matters So Much Here

Antipsychotic medications are powerful drugs that slow down brain activity. For people with dementia, they are prescribed off-label to manage severe agitation, aggression, hallucinations, or delusions when non-drug approaches have not worked. However, the U.S. Food and Drug Administration (FDA) has issued a black box warning—the strongest safety alert—because these drugs increase the risk of death in older adults with dementia-related psychosis. The risk is about 1.6 to 1.7 times higher than with placebo, with most deaths due to heart problems or infections like pneumonia. This is not a decision to be made lightly or alone.

Shared decision-making means that you, your loved one (as much as they are able), and the clinician work together as a team. The goal is not simply to say yes or no to a prescription. Instead, it is to fully understand the person's specific situation: what behaviors are happening, what might be causing them (like pain, infection, or an uncomfortable environment), what non-drug strategies have been tried, and what the realistic benefits and harms of medication would be. This process ensures that the person's values and preferences are honored, and that the treatment plan is tailored to them.

What the Research and Guidelines Say

Multiple expert guidelines, including those from the National Institute for Health and Care Excellence (NICE) and the American Academy of Family Physicians (AAFP), stress that before starting an antipsychotic, you must have a documented discussion about benefits and harms with the person and their family or carers. NICE has even created a patient decision aid specifically for antipsychotic medicines for agitation, aggression, and distress in dementia. This tool helps structure the conversation so nothing important is missed.

Experts also emphasize that antipsychotics should only be used when non-drug strategies have failed and the symptoms are causing significant distress to the person or danger to themselves or others. The drugs should be started at the lowest effective dose, used for the shortest possible time, and regularly reviewed. Many people can eventually be tapered off, especially if the underlying trigger (like an infection or pain) has been resolved. The Iowa Geriatric Education Center's IA-ADAPT program provides free decision-support materials to help clinicians and families work through this process.

General caregiving information, not medical advice. Check medications and major care changes with your clinician.

Step-by-step

  1. Start by scheduling a dedicated appointment with the prescribing clinician (often a geriatrician, psychiatrist, or neurologist) specifically to discuss antipsychotic use. Do not let this be a quick conversation during a routine check-up. Bring a list of your loved one's current behaviors, when they happen, what seems to trigger them, and what you have already tried (like distraction, redirection, or addressing pain).

  2. Ask the clinician to review all current medications, including over-the-counter drugs and supplements. Many medications can cause confusion, sedation, or falls, especially those with anticholinergic effects (like some bladder control or allergy meds). Reducing or stopping these may improve behavior without adding a new drug.

  3. Request a thorough medical workup to rule out physical causes of behavior changes. Common culprits include urinary tract infections, constipation, pain (from arthritis or an injury), dehydration, or delirium from another illness. Treating these can often resolve the agitation without antipsychotics.

  4. Use a structured decision aid together with the clinician. Ask for the NICE patient decision aid on antipsychotics for dementia, or a similar tool. Go through it page by page, discussing the person's specific risk factors (like heart disease or Parkinson's), the expected benefits (reduction in severe agitation or psychosis), and the potential harms (increased risk of death, stroke, falls, sedation, and worsening of Parkinson's symptoms).

  5. Document the discussion and the decision. Ask the clinician to write a note in the medical record that says: 'Discussed FDA black box warning for increased mortality with antipsychotics in dementia. Discussed risks of stroke, falls, sedation, and extrapyramidal symptoms. Discussed non-pharmacologic alternatives tried. Decision made to [start/not start/continue/discontinue] [drug name and dose].' This protects everyone and ensures the conversation happened.

  6. If the decision is to start an antipsychotic, agree on a specific target symptom (e.g., 'reduce physical aggression toward caregiver during bathing') and a time frame to evaluate (usually 2-4 weeks). Ask for the lowest possible starting dose. Also agree on how you will monitor for side effects like drowsiness, confusion, stiffness, or trouble swallowing.

  7. Schedule a follow-up appointment within 2-4 weeks to review progress. If there is no clear improvement in the target symptom, the medication should be tapered and stopped. If there is improvement, discuss a plan for gradual dose reduction (GDR) after a few months, as many people can be successfully weaned off.

  8. If the decision is not to start an antipsychotic, ask for a written plan for non-drug strategies. This might include a referral to a dementia behavior specialist, an occupational therapist for environmental modifications, or a social worker for caregiver support. Also ask for a plan to reassess if behaviors worsen.

What not to do

  • Do not agree to start an antipsychotic without a clear, documented discussion of the FDA black box warning. Many lawsuits have occurred when a patient died and the family was never told about the increased mortality risk. Instead, insist on a conversation where the clinician explicitly states the risks and you both sign off on the decision.

  • Do not assume that because a behavior is distressing, it must be treated with medication. Many behaviors are caused by unmet needs like hunger, thirst, need to toilet, or boredom. Always try non-drug approaches first, such as validation, distraction, or a soothing activity. The goal is to relieve the person's psychological pain, not just to make them easier to manage.

  • Do not accept a prescription for an antipsychotic without a clear target behavior and a time-limited trial. If the drug is started 'to see if it helps' without a specific goal, it is likely to be continued indefinitely even if it is not working. Instead, agree on one symptom to track and a date to review.

  • Do not stop an antipsychotic abruptly without medical guidance, especially if it has been used for more than a few weeks. Sudden withdrawal can cause rebound psychosis or agitation. Instead, work with the clinician to taper the dose slowly over weeks or months.

  • Do not assume that a 'low dose' is safe. Even low doses of antipsychotics carry the black box warning and can cause falls, sedation, and cognitive decline. The goal is to use the lowest effective dose for the shortest time, not to minimize risk to zero.

Practical tools

  • NICE Patient Decision Aid on Antipsychotics for Dementia

    This is a free, downloadable tool that walks you through the pros and cons of antipsychotic medication. It includes questions to ask the doctor, a list of non-drug alternatives, and a place to write down your loved one's values and preferences. Ask your clinician for a copy or find it online at the NICE website.

  • IA-ADAPT Program (Improving Antipsychotic Appropriateness in Dementia Patients)

    Hosted by the Iowa Geriatric Education Center, this free online program provides decision-support materials, including algorithms for when to start and stop antipsychotics, and monitoring checklists. It is designed for clinicians but can be shared with families to understand the process. All materials are free after a simple registration.

  • Behavior Tracking Log

    Create a simple daily log to record: time of behavior, what happened before (trigger), what the behavior looked like, what you tried, and what happened after. Bring this to every appointment. It helps the clinician see patterns and decide if medication is truly needed. Example: 'Tuesday 3pm, after toileting, began yelling and hitting. Used calm voice and offered a snack. Behavior stopped after 10 minutes.'

  • The 'Unmet Needs' Checklist

    Before considering medication, run through this checklist: Is the person in pain? (Check for grimacing, guarding, or moaning.) Are they hungry or thirsty? Do they need to use the bathroom? Are they too hot or cold? Are they bored or overstimulated? Are they experiencing a side effect from another drug? Treating the need often resolves the behavior.

  • Sample Script for the Doctor Visit

    Say: 'We are considering an antipsychotic for my mother's agitation. I understand there is a black box warning about increased risk of death. Can we review the specific risks for her, given her heart condition? What non-drug options have we not tried yet? If we start the drug, what is the target symptom and how will we know if it's working? When will we review it? And how will we taper it off later?'

  • Medication Review Checklist

    Ask the pharmacist or doctor to review all drugs for anticholinergic burden (drugs that can worsen confusion). Common ones include diphenhydramine (Benadryl), oxybutynin (Ditropan), and some antidepressants like amitriptyline. Reducing or stopping these can improve alertness and reduce falls.

Discuss with your clinician

What is the specific FDA black box warning for this drug, and how does it apply to my loved one's health conditions (heart disease, diabetes, history of stroke)?

What is the exact target symptom we are trying to treat, and how will we measure success?

What is the plan for gradual dose reduction if the drug is started? When will we first try to reduce the dose?

Are there any drug interactions with my loved one's current medications (including over-the-counter and supplements)?

What are the signs of serious side effects I should watch for, such as new-onset stiffness, trouble swallowing, severe drowsiness, or falls?

If my loved one has Parkinson's disease or Lewy body dementia, which antipsychotics are safest, and what is the risk of a severe sensitivity reaction?

Can we try a non-drug approach first, such as a referral to a dementia behavior specialist or an occupational therapist?

How will we document this discussion in the medical record to ensure everyone is on the same page?
