Dementia: Medicines to Treat Behavior Changes
The decision to try medicine to treat behavior problems in Alzheimer's disease is different for each person. The decision weighs the risks and benefits of these medicines. Your doctor can help you decide. Medicines for behavior problems linked to dementia do not work very well for most people and may have serious risks.
Medicines can be used to treat behavior problems caused by Alzheimer's disease and other diseases that cause dementia. They should be used only after other nondrug approaches have failed to improve a person's symptoms. Medicine may be needed when the person is in danger of harming himself or herself or others or when the caregiver is unable to deal with the situation using other means.
Antipsychotic medicines may help relieve more severe agitation or psychosis (disordered thought processes).
Examples of medicines sometimes used to treat hallucinations, paranoia, and severe agitation in people with dementia include haloperidol (Haldol), risperidone (Risperdal), quetiapine (Seroquel), and olanzapine (Zyprexa).
FDA advisory. The U.S. Food and Drug Administration (FDA) has issued an advisory stating that people with dementia who use antipsychotics may die sooner than those who don't use these drugs. Examples of these antipsychotics include haloperidol (Haldol), olanzapine (Zyprexa), quetiapine (Seroquel), and risperidone (Risperdal).
Antianxiety medicines, including minor tranquilizers, relieve anxiety and mild agitation and may help calm the person. But they can cause drowsiness if the dose is too high. When minor tranquilizers are needed, short-term or occasional use often is better than continuous use.
Anticonvulsant medicines, such as carbamazepine (Tegretol) or valproic acid (Depakene), may be used to control agitation, violent behavior, and mood swings caused by dementia. But the U.S. Food and Drug Administration (FDA) has not approved their use for this specific problem.
FDA advisory. The U.S. Food and Drug Administration (FDA) has issued a warning on anticonvulsants and the risk of suicide and suicidal thoughts. The FDA does not recommend that people stop using these medicines. Instead, people who take anticonvulsant medicine should be watched closely for warning signs of suicide. People who take anticonvulsant medicine and who are worried about this side effect should talk to a doctor.
Other medicines that may be used to treat agitation include trazodone or a selective serotonin reuptake inhibitor (SSRI) such as fluoxetine (Prozac), sertraline (Zoloft), citalopram (Celexa), or escitalopram (Lexapro). But research on the effectiveness of these medicines in Alzheimer's disease and other dementias is limited.
FDA advisory. The U.S. Food and Drug Administration (FDA) has issued an advisory on antidepressant medicines and the risk of suicide. The FDA does not recommend that people stop using these medicines. Instead, a person taking antidepressants should be watched for warning signs of suicide. This is especially important at the beginning of treatment or when the doses are changed.
