Is Seroquel Safe for People with Alzheimer’s Disease
Alzheimer’s disease is a progressive brain disorder that affects memory, thinking, and behavior. As the disease advances, many people with Alzheimer’s experience agitation, aggression, hallucinations, or delusions. These symptoms can be distressing for both the person with dementia and their caregivers. Doctors sometimes prescribe medications like Seroquel (generic name: quetiapine) to help manage these challenging behaviors. But is Seroquel actually safe for people with Alzheimer’s disease? The answer is complex and requires a careful look at the evidence, risks, and alternatives.
What Is Seroquel?
Seroquel is an antipsychotic medication. It is mainly used to treat schizophrenia, bipolar disorder, and sometimes major depression. In some cases, doctors also prescribe it “off-label” for agitation and psychosis in people with dementia, including Alzheimer’s disease. Seroquel works by affecting certain chemicals in the brain, such as dopamine and serotonin, which can help calm agitation and reduce psychotic symptoms.
The Risks of Seroquel in Alzheimer’s Disease
Despite its use, Seroquel is not officially approved by the U.S. Food and Drug Administration (FDA) for treating behavioral symptoms in dementia. More importantly, the FDA has issued a “black box warning”—the strongest warning the agency gives—about using antipsychotics like Seroquel in elderly patients with dementia. This warning states that these drugs are associated with an increased risk of death in older adults with dementia-related psychosis[5]. The exact reasons for this increased risk are not fully understood, but it may be related to heart problems, infections, or other serious side effects.
In addition to the risk of death, Seroquel can cause other serious side effects, especially in older adults. These include dizziness, falls, confusion, stroke, abnormal heart rhythms, and worsening of cognitive function[2]. Elderly patients with dementia are particularly vulnerable to these side effects, and even low doses can be problematic. For these reasons, most experts recommend avoiding Seroquel in people with Alzheimer’s disease unless absolutely necessary and after all other options have been tried[5].
Are There Any Benefits?
Some doctors still prescribe Seroquel for severe agitation or psychosis in dementia when non-drug approaches have failed. When used, it is usually started at a very low dose (for example, 12.5 mg twice daily) and increased slowly if needed, but not exceeding 200 mg twice daily[6]. The goal is to use the lowest effective dose for the shortest possible time. However, even at these doses, the risks remain significant, and the benefits are often modest at best.
Alternatives to Seroquel
Because of the risks, experts recommend trying non-drug strategies first. These include creating a calm environment, establishing routines, addressing pain or discomfort, and using behavioral therapies. If medications are needed, other options may be considered, depending on the specific symptoms.
For agitation specifically related to Alzheimer’s disease, a newer medication called brexpiprazole has been approved by the FDA. Clinical trials have shown that brexpiprazole can reduce agitation in people with Alzheimer’s, and it may have a better safety profile than older antipsychotics like Seroquel[1]. However, it is still important to use any medication cautiously and under close medical supervision.
Other treatments, such as lecanemab, target the underlying disease process in early Alzheimer’s by reducing amyloid plaques in the brain, but these are not used for behavioral symptoms like agitation[4].
What Should Caregivers and Families Know?
If a loved one with Alzheimer’s is prescribed Seroquel, it is important to understand the risks and to ask the doctor why this medication is being recommended. Families should watch for any new or worsening symptoms, such as increased confusion, falls, or changes in mood or behavior. Any concerns should be discussed with the healthcare provider right away.
Regular medication reviews are also important. Sometimes, medications that were started during a crisis can be reduced or stopped as the situation improves. A pharmacist or geriatric specialist can help review all medications to make sure they are still necessary and to minimize side effects.
The Bigger Picture
The use of antipsychotics like Seroquel in dementia is controversial. While these drugs can sometimes help with severe symptoms, the risks often outweigh the benefits, especially in the long term[4][5]. Ongoing research is looking for safer and more effective ways to manage behavioral symptoms in Alzheimer’s disease.
In summary, Seroquel is generally not considered safe for people with Alzheimer’s disease due to the increased risk of death and other serious side effects[5]. It should only be used as a last resort, at the lowest possible dose, and for the shortest time necessary. Families and caregivers should be fully informed about the risks and should explore all other options before agreeing to this treatment.
