Anti-anxiety medications and the elderly — the benzodiazepine concern

Reviewed by Dr. Maria Chen, PharmD

Benzodiazepines like lorazepam and alprazolam work fast for anxiety but dramatically increase fall risk, cause cognitive impairment, and are addictive in older adults. The American Geriatrics Society Beers Criteria recommends avoiding them entirely in this age group. Safer alternatives, including SSRIs, buspirone, and therapy, treat anxiety effectively without those dangers.

Your parent is worried all the time. They worry about money, about their health, about whether they locked the door, about things that happened decades ago. The worry interferes with their sleep, their appetite, their ability to enjoy life. Their doctor offers medication and it sounds like a solution. Finally, something to make the worry stop. But benzodiazepines, which are the medications doctors most commonly reach for with anxiety, are genuinely risky in older adults, and you should understand what you're agreeing to if your parent takes them.

Benzodiazepines like lorazepam, alprazolam, and clonazepam work quickly. Your parent takes a pill and within an hour, they feel calmer. The anxiety doesn't completely disappear, but the edges are taken off. They can think more clearly. Their nervous system settles down. For someone in acute anxiety, this is a relief. The problem is that they're also addictive, they increase fall risk significantly in older adults, and they can cause cognitive changes that look like dementia. The guidelines for older adults actually recommend avoiding benzodiazepines entirely because the risks are so high.

Yet they're still prescribed frequently because anxiety in older adults is real and distressing, and people want relief. Your job is understanding the risks and making sure your parent is taking the lowest dose for the shortest time possible. This isn't about being tough or refusing your parent something that might help. It's about preventing serious harm.

Understanding Anxiety in Older Adults

Before treating anxiety with medication, the doctor should rule out medical causes like thyroid disease, heart arrhythmias, and urinary tract infections, all of which can produce anxiety symptoms in older adults. Thyroid disease causes anxiety. Heart arrhythmias cause anxiety. Infections, especially urinary tract infections, can cause anxiety in older adults. Before jumping to anxiety medication, the doctor should rule out medical causes. A simple blood test can check thyroid function. An EKG can check the heart. A urinalysis can rule out infection. If the doctor prescribes medication without checking these things, that's a red flag.

Situational anxiety is anxiety that comes from something specific. Your parent is anxious about an upcoming surgery, or anxious after something scary happened. This kind of anxiety might respond well to medication for a short time, as something to get through the situation. Once the situation resolves, the medication can stop.

Generalized anxiety disorder is anxiety that's ongoing, not tied to specific situations. Your parent worries about everything, all the time. This is more likely to be treated with medication long-term. But even here, medication should be part of a broader approach that includes therapy, lifestyle changes, and stress management.

Sometimes anxiety in older adults is actually depression wearing a different mask. Your parent feels anxious, but underneath is hopelessness and despair. Treating only the anxiety while missing the depression won't help. Your parent might need an antidepressant, not an anti-anxiety medication.

The Benzodiazepine Problem

Benzodiazepines increase fall risk by 40-60% in older adults, according to multiple studies cited by the CDC, and they cause cognitive impairment, physical dependence, and dangerous drug accumulation due to slower metabolism. They affect balance and coordination. Your parent takes a dose and their body doesn't respond as quickly to balance challenges. They're more likely to fall. If they do fall, they're on a blood thinner or have osteoporosis, and a fall might be catastrophic. Hip fracture, head injury, and subsequent rapid decline. This is real danger, not a theoretical maybe.

They also cause cognitive changes. Your parent becomes confused or forgetful. They can't remember what they did yesterday. They have trouble following conversations. They might become more aggressive or irritable. These changes are dose-related and reversible if you stop the medication, but while taking it, your parent's thinking is impaired.

Benzodiazepines are addictive. Your parent might start taking them for anxiety, then find they can't sleep without them, can't manage anxiety without them. The brain adapts to the medication. Stopping becomes difficult. Stopping too quickly causes rebound anxiety, where the anxiety is worse than it was before the medication. Getting off benzodiazepines requires slowly reducing the dose over weeks or months.

Older adults metabolize benzodiazepines slowly. A dose that would leave a younger person's system in a day might stay in an older person's system for multiple days. This means accumulation over time. Your parent takes a dose and some of the previous dose is still there. This increases risk of side effects.

The Beers Criteria, which is a list of medications to avoid in older adults, specifically recommends against benzodiazepines. This is based on evidence that they cause harm in this population. Yet they're still prescribed because treating acute anxiety is difficult without them, and the desire for relief is strong.

Better Options

SSRIs are the first-line treatment for anxiety in older adults because they are effective, non-addictive, and do not impair cognition or increase fall risk the way benzodiazepines do. Medications like sertraline, citalopram, and paroxetine take a few weeks to work, which makes them less helpful for acute anxiety. But for ongoing anxiety, they're excellent. They're not addictive. They don't impair cognition. They have side effects, but those are usually manageable. Sertraline might cause diarrhea or sleep problems. Citalopram might cause low sodium if doses are too high. But these are manageable compared to benzodiazepines.

If your parent is also depressed, an SSRI is definitely the right choice because it treats both conditions. If your parent is only anxious with no depression, an SSRI still works for anxiety.

Therapy, particularly cognitive behavioral therapy, works for anxiety. Your parent meets with a therapist and learns techniques to manage anxious thoughts and the physical symptoms of anxiety. Therapy can be as effective as medication and actually teaches your parent skills they can use forever. The problem is that therapy takes work and takes time, and your parent might want quicker relief.

Buspirone is a non-benzodiazepine anti-anxiety medication that works by affecting serotonin. It doesn't cause dependence, doesn't impair cognition as much, and is safer in older adults. It's less potent than benzodiazepines, but for milder anxiety, it can work.

Lifestyle approaches include exercise, which genuinely helps anxiety. Meditation or yoga can help. Limiting caffeine and alcohol help. Sleep improves anxiety. Making sure your parent is getting adequate nutrition and staying socially connected helps. Some of these things work as well as medication.

When Benzodiazepines Are Still Used

Short-term use for a specific crisis, like the night before surgery or during a disabling panic attack, is sometimes appropriate, but daily long-term use is not. If your parent is having severe acute anxiety that's preventing them from functioning, a short course of a benzodiazepine might help them get through. A surgery that your parent is terrified of might warrant a benzodiazepine the night before and the morning of. A panic attack that's truly disabling might need benzodiazepine.

The key is that it should be short-term. Your parent takes it for a specific situation or for a limited time while starting an SSRI, then stops. Not indefinitely. Not every day forever. The risks are too high for that.

If your parent is already on benzodiazepines and has been for years, stopping isn't necessarily the right answer either. Stopping too quickly can cause serious withdrawal. But your parent and the doctor should talk about whether continuing is still necessary and whether alternatives might work. Sometimes slowly tapering is the answer. Sometimes staying on a low dose is the lesser evil if stopping causes such severe rebound anxiety that your parent can't function.

If your parent does take benzodiazepines, even short-term, fall prevention becomes even more important. Remove trip hazards. Make sure they're wearing appropriate shoes. Make sure they're using a cane or walker if they need one. Grab bars in the bathroom. Good lighting. These things matter even more when your parent is taking something that affects balance.

Your parent's anxiety is real and deserves treatment. But benzodiazepines are a risky choice for older adults. SSRIs, therapy, buspirone, and lifestyle changes often work just as well without the severe downsides. If your parent is on a benzodiazepine, understand why and whether it's still necessary. If a doctor wants to start benzodiazepines, ask about trying an SSRI first. Your parent can be less anxious and stay safer at the same time.

Frequently Asked Questions

My parent has been on a benzodiazepine for years. Should they stop?

Stopping abruptly after long-term use is dangerous and can cause seizures. Talk to their doctor about a slow taper over weeks or months. Sometimes staying on a low dose is the safest option if previous taper attempts caused severe rebound anxiety. This is a decision to make with medical guidance, not on your own.

Are SSRIs safe for older adults with heart conditions?

Most SSRIs are safe for older adults with heart conditions, and sertraline is often the preferred choice because it has the most safety data in cardiac patients. The doctor will monitor for side effects like low sodium, which can occur at higher doses, especially when combined with diuretics.

How long do SSRIs take to work for anxiety?

Two to four weeks for initial improvement, with full benefit often taking six to eight weeks. This waiting period is difficult when your parent is suffering, but the long-term safety profile makes the wait worthwhile compared to the immediate but dangerous relief benzodiazepines provide.

Can therapy really help an older adult with anxiety?

Yes. Cognitive behavioral therapy is effective for anxiety at any age, and research shows older adults respond well to it. The challenge is finding a therapist who accepts Medicare and has experience with older patients. Ask the doctor for a referral or contact your local Area Agency on Aging for resources.
