What medications can exacerbate the cognitive (thinking) symptoms of dementia or increase the risk of complications?
When managing dementia, certain medications can worsen cognitive symptoms or have harmful interactions with dementia medications. It's crucial to avoid or carefully manage the use of these drugs in people with dementia:
Anticholinergics
Examples: Diphenhydramine (Benadryl), Oxybutynin (Ditropan), Tolterodine (Detrol), Amitriptyline, and certain antihistamines.
Reason to Avoid: Anticholinergics block acetylcholine, a neurotransmitter important for memory and learning, which is already deficient in people with dementia. These drugs can worsen confusion, memory loss, and overall cognitive function .
Benzodiazepines
Examples: Diazepam (Valium), Lorazepam (Ativan), Clonazepam (Klonopin).
Reason to Avoid: Benzodiazepines can cause sedation, confusion, and increased risk of falls. They may also exacerbate memory problems and can lead to dependence and withdrawal symptoms, which can further complicate dementia management .
Opioids
Examples: Morphine, Codeine, Oxycodone.
Reason to Avoid: Opioids can cause sedation, confusion, and respiratory depression. They may also increase the risk of falls and can exacerbate cognitive impairment .
Antipsychotics
Examples: Haloperidol (Haldol), Olanzapine (Zyprexa), Risperidone (Risperdal).
Reason to Avoid: While sometimes used to manage severe behavioral symptoms, antipsychotics carry significant risks in dementia patients, including an increased risk of stroke, sedation, and increased mortality, particularly in elderly patients .
Barbiturates
Examples: Phenobarbital, Secobarbital.
Reason to Avoid: Barbiturates can cause significant sedation, confusion, and an increased risk of falls. They can also exacerbate memory problems .
Certain Muscle Relaxants
Examples: Cyclobenzaprine (Flexeril), Carisoprodol (Soma).
Reason to Avoid: These drugs can cause sedation, confusion, and can worsen cognitive impairment in people with dementia .
Tricyclic Antidepressants (TCAs)
Examples: Amitriptyline, Nortriptyline.
Reason to Avoid: TCAs have strong anticholinergic effects, which can worsen memory and other cognitive functions. They also pose a risk for cardiovascular side effects .
Certain Sleep Aids
Examples: Zolpidem (Ambien), Eszopiclone (Lunesta).
Reason to Avoid: These medications can cause confusion, dizziness, and an increased risk of falls, particularly in older adults .
Anti-Parkinson Drugs
Examples: Trihexyphenidyl, Benztropine.
Reason to Avoid: These drugs can have anticholinergic effects, which can exacerbate cognitive decline in dementia patients .
Antihistamines
Examples: Diphenhydramine (Benadryl), Chlorpheniramine.
Reason to Avoid: Many over-the-counter antihistamines have anticholinergic properties, which can worsen dementia symptoms .
General Recommendations:
Always consult with a healthcare provider before starting, stopping, or changing any medication regimen in a person with dementia.
Non-drug approaches to managing symptoms, such as behavioral therapies, should be prioritized when possible to minimize the use of these potentially harmful medications.
These medications should be used with caution or avoided in individuals with dementia due to their potential to worsen cognitive symptoms and increase the risk of other complications.
