Anxiety Treatment Options Compared: CBT, SSRIs, Buspirone, Benzodiazepines and More

The first-line treatments for anxiety disorders are cognitive behavioral therapy (CBT) and an SSRI or SNRI antidepressant. For generalized anxiety disorder (GAD), UK guidance treats them as equal choices and leaves the decision to your preference. In the US, escitalopram, paroxetine, duloxetine, extended-release venlafaxine and buspirone carry FDA approval for GAD or for anxiety symptoms that roughly correspond to it.

Benzodiazepines work fast but are best kept to short-term use because of the risks of dependence and withdrawal, which the FDA highlighted in a 2020 boxed warning. Other medicines, such as hydroxyzine and pregabalin, have narrower roles.

Anxiety treatments side by side

The type of anxiety shapes the plan

"Anxiety" covers several distinct conditions, and the treatments with the most support differ in emphasis:

• Generalized anxiety disorder: persistent, hard-to-control worry about many things. In UK guidance, CBT, applied relaxation and an SSRI are first-line, with an SNRI as an alternative if the first SSRI does not work.
• Panic disorder: recurrent, unexpected panic attacks and fear of the next one. NICE recommends CBT, usually completed within four months, and antidepressants as the only medication for longer-term management. It advises against benzodiazepines for panic disorder because they are associated with poorer long-term outcomes.
• Social anxiety disorder: intense fear of judgment in social or performance situations. Paroxetine and venlafaxine XR are among the medicines FDA-approved for it.
• OCD and PTSD: these are treated with their own specialized therapies, such as exposure-based treatments, and have their own medication approvals; paroxetine, for example, is FDA-approved for both.

Anxiety also commonly travels with depression, insomnia, ADHD or substance use. When it does, the plan needs to address both conditions, which is one reason a full evaluation is worth more than a quick prescription. The site's explainer on generalized anxiety disorder describes how GAD is diagnosed.

Each of these has its own guide in this series: panic disorder treatment, social anxiety disorder treatment and OCD treatment options compared.

Therapy: CBT and applied relaxation

For GAD, NICE uses a stepped approach. People start with education and active monitoring, move to low-intensity help such as guided self-help, and then, if symptoms persist or cause marked impairment, choose between a high-intensity psychological treatment and medication. The psychological options are CBT or applied relaxation, each usually 12 to 15 weekly one-hour sessions.

CBT for anxiety teaches you to notice and test anxious predictions, to reduce avoidance and reassurance-seeking, and to tolerate uncertainty. Applied relaxation trains you to relax quickly in the situations that trigger anxiety. For panic disorder and OCD, a meta-analysis found that adding psychotherapy to medication produced better results than medication alone, with effects lasting up to two years.

The site's page on CBT for anxiety describes what sessions involve. If you are weighing therapy against medication more broadly, medication, therapy or both summarizes the evidence.

CBT is not the only structured therapy with evidence for anxiety. Acceptance and commitment therapy (ACT) takes a different stance toward anxious thoughts, focusing on acting on your values while the thoughts are present rather than disputing them; ACT vs CBT explains when each may suit you better.

Lower-intensity options and what to do while you wait

Not everyone needs, or can quickly get, a full course of weekly therapy. In NICE's stepped approach for GAD, the step before high-intensity therapy or medication is low-intensity help, such as guided self-help based on CBT principles, for people whose symptoms have not improved with education and monitoring. These options can be a reasonable starting point for milder symptoms, or a bridge while you wait for a therapist.

A bridge works best with structure: a workbook or program based on CBT, a fixed time each day to practice, a simple weekly rating of your worry, and a date to review progress with a clinician. If symptoms are severe, getting worse, or causing you to avoid work, school or daily tasks, move to the next step rather than waiting it out.

Daily medicines: SSRIs, SNRIs and buspirone

US labels show which antidepressants are FDA-approved for GAD. Escitalopram is approved for GAD in adults and children 7 and older; paroxetine for GAD in adults, along with panic disorder, social anxiety disorder, OCD and PTSD; duloxetine for GAD in adults and children 7 and older; and venlafaxine XR for GAD, social anxiety disorder and panic disorder in adults. Other SSRIs are also widely used for anxiety, and NICE suggests sertraline first in the UK on cost-effectiveness grounds.

These medicines take weeks to work, and some people feel jittery or more anxious in the first days. Starting low and increasing slowly can help. Sexual side effects, such as lower libido or delayed orgasm, are a known effect of SSRIs, and the label asks prescribers to ask about them directly because people often do not raise them. The site's guides on the first two weeks on an SSRI and SSRI activation and anxiety cover this early phase.

Continuing matters. In a 2017 BMJ meta-analysis of 28 relapse-prevention trials, about 36% of people with anxiety disorders who were switched to placebo relapsed, compared with about 16% who stayed on their antidepressant. Stopping should be planned with your prescriber and done gradually; labels recommend a gradual reduction rather than abrupt stopping whenever possible.

All antidepressants carry an FDA boxed warning about increased suicidal thoughts and behaviors in children, adolescents and young adults in short-term trials, so the first weeks of treatment call for closer follow-up. How a prescriber chooses among these drugs is covered in SSRI, SNRI or bupropion.

Buspirone

Buspirone is FDA-approved for managing anxiety disorders and for short-term relief of anxiety symptoms; its trials were in people whose diagnosis roughly corresponded to GAD. It must be taken every day for three to four weeks to reach full effect, and it does not work on an as-needed basis. Because it is taken daily rather than as needed, it is a maintenance option, not a rescue medicine. Ask your prescriber how it fits with any other medication you take.

Benzodiazepines: useful short-term, risky long-term

Benzodiazepines such as alprazolam, clonazepam and lorazepam relieve anxiety quickly. In September 2020 the FDA required the Boxed Warning for all benzodiazepines to be updated to describe the risks of abuse, misuse, addiction, physical dependence and withdrawal reactions. The FDA urges particular caution when combining them with opioids or other sedating medicines, advises against drinking alcohol while taking them, and says people taking them should not stop suddenly.

NICE advises against benzodiazepines for GAD except as a short-term measure during crises. NIMH notes that long-term use may lead to tolerance or dependence, which is why prescribers usually limit them to short periods and taper slowly. If you have taken one regularly for some time, any reduction should be planned with your prescriber; never stop a benzodiazepine on your own.

Hydroxyzine, pregabalin and beta-blockers

Hydroxyzine is an antihistamine labeled for symptomatic relief of anxiety and tension. Its label notes that effectiveness for more than four months has not been assessed in systematic studies and that drowsiness can occur, usually easing within a few days. It must not be used by people with a prolonged QT interval, a heart-rhythm problem, and should be used with caution in people at risk of one.

Pregabalin is FDA-approved in the US for nerve pain, fibromyalgia and as add-on treatment for partial-onset seizures, not for anxiety, and it is a Schedule V controlled substance. UK guidance allows it for GAD when SSRIs and SNRIs are not tolerated. In the US, prescribing it for anxiety is off-label.

Beta-blockers are sometimes prescribed off-label for short-term physical symptoms of anxiety, such as a racing heart or tremor before public speaking. They are generally not recommended for people with asthma or diabetes. Propranolol for performance anxiety explains who it suits, and hydroxyzine vs benzodiazepines compares the two fast-acting options.

Special situations that change the choice

Older adults

Medicines that are reasonable for a younger adult can carry more risk after 65. The American Geriatrics Society's 2023 Beers Criteria, which apply to adults 65 and older, list benzodiazepines among medications to avoid in most older adults, because they increase the risk of cognitive impairment, delirium, falls, fractures and motor vehicle crashes. The same criteria note that benzodiazepines may still be appropriate in a few situations, including severe generalized anxiety disorder. Hydroxyzine and paroxetine also appear on the list of medications to avoid, because they are highly anticholinergic. None of this means an older adult should stop a current medication on their own; it means any plan deserves a careful review with the prescriber.

Children and teens

CBT is a common starting point for young people, often with parents involved. When medication is considered, escitalopram and duloxetine are FDA-approved for GAD from age 7. The antidepressant boxed warning about suicidal thoughts and behaviors in children, adolescents and young adults applies, so early follow-up should be close. Child anxiety treatment options covers parent-led programs and how to judge progress.

Pregnancy, breastfeeding and perimenopause

Planning a pregnancy, being pregnant or breastfeeding changes the balance of risks for every option, including untreated anxiety. Have that conversation before conception if you can; psychiatric medications during pregnancy sets out how to weigh it. Anxiety that starts or worsens in midlife may be linked to perimenopause, which opens additional options; see perimenopause anxiety treatment.

Anxiety with alcohol or other substance use

Alcohol can feel like it calms anxiety in the moment, but it is not a treatment, and it is a reason for particular caution with benzodiazepines, and the FDA advises against drinking alcohol while taking them. Be candid with your prescriber about how much you drink; psychiatric medications and alcohol explains the specific interactions.

Lifestyle and supplements

Daily habits will not replace treatment for a moderate or severe anxiety disorder, but they can lower the baseline. Regular physical activity, consistent sleep, and cutting back on caffeine and alcohol are reasonable steps for most people, and many find that caffeine in particular amplifies a racing heart and restlessness. The site's guides on exercise and anxiety and breathing techniques offer practical starting points.

Evidence for supplements is limited. The National Center for Complementary and Integrative Health describes studies of chamomile and of an oral lavender product as preliminary or inconclusive, and notes that kava has been linked to severe liver injury. Supplements can also interact with medicines, so tell your prescriber what you take. The site's pages on natural anxiety remedies and supplements in psychiatry discuss specific products with that caution in mind.

Cannabis and CBD

Many people try cannabis or CBD products for anxiety. The FDA has not approved a marketing application for cannabis to treat any disease or condition, and the only CBD product it has approved, Epidiolex, is for seizures associated with specific epilepsy syndromes. The agency notes that selling CBD products with unsupported therapeutic claims is illegal and that such claims can lead people to put off treatments that work. If you use either, tell your prescriber, since both can affect sleep, mood and other medications.

Combining treatments, and how long treatment lasts

Therapy and medication are not either-or choices. Many people start one and add the other, and for panic disorder and OCD the trial evidence favors combining them. The order often depends on practical things: how quickly a skilled therapist is available, how severe the symptoms are, past experience with medication, and personal preference, which UK guidance treats as the deciding factor for GAD.

Duration is a separate decision. A course of CBT has a planned length. Medication usually continues for a period after you feel well, because stopping early raises the chance of relapse. When you and your prescriber decide it is time to stop, the dose is reduced gradually rather than stopped all at once.

How to tell whether treatment is working

Progress is easier to judge with a number. The GAD-7 is a seven-item questionnaire validated for screening GAD and rating its severity, and many clinicians repeat it every few weeks. PHQ-9 and GAD-7 scores explained shows how to read your numbers. A falling score over several weeks suggests the plan is on track; a flat score after a fair trial is a reason to review it, not to keep waiting. Alongside the score, notice practical changes: fewer avoided situations, less time spent worrying, better sleep, and fewer requests for reassurance.

Questions worth asking at the start of any treatment:

1. How long until we expect to see a change, and how will we measure it?
2. What side effects are common in the first weeks, and which should I report right away?
3. If this helps only partly, what is the next step?
4. If I take medication, how long do you expect I will continue it, and how would we stop it safely?

When the first treatment does not work

A first treatment that helps only partly is common, and it is not a sign that nothing will work. Before changing course, a prescriber or therapist will usually check four things: whether the trial was long enough, whether the dose or the number of sessions was adequate, whether the medication was taken as prescribed or the therapy practiced between sessions, and whether the diagnosis is right.

If the first SSRI has had a fair trial without enough benefit, UK guidance suggests offering a different SSRI or an SNRI, weighing withdrawal tendency, side effects, interactions and past experience with each drug. Adding therapy to medication is another route, with trial evidence of benefit in panic disorder and OCD. If SSRIs and SNRIs are not tolerated, NICE lists pregabalin as an option; in the US that use is off-label. Buspirone is sometimes considered as well; buspirone vs SSRIs for anxiety compares the two, and gabapentin and pregabalin in psychiatry covers their evidence and risks.

It is also worth asking whether something else is driving the symptoms. Thyroid problems, heavy caffeine use, some medications, sleep disorders and untreated ADHD can all look like, or amplify, anxiety. Medical conditions to rule out before a psychiatric diagnosis lists the common ones, and ADHD and anxiety together covers that particular overlap.

Common mistakes in anxiety treatment

• Stopping an SSRI or SNRI in the first two weeks because of early side effects, before it has had time to work. Call the prescriber instead; the dose or timing can often be adjusted.
• Expecting buspirone to work like a rescue medication. It needs daily use for weeks.
• Letting an as-needed benzodiazepine quietly become a daily one. If that happens, raise it with your prescriber rather than changing it yourself.
• Attending CBT sessions without doing the practice between them. CBT asks for regular attendance and work between sessions, and skipping the second part weakens it.
• Adding several supplements at once without telling anyone.
• Ignoring sleep. Insomnia and anxiety feed each other, and insomnia has its own effective treatment; see insomnia treatment options compared.
• Stopping medication as soon as you feel better. Relapse is more common after stopping than after continuing, so plan the timing and the taper with your prescriber.

How to choose a starting point

• Mild, recent symptoms: guided self-help, sleep, activity and caffeine changes, and review in a few weeks.
• Persistent symptoms that limit work, relationships or sleep: CBT or an SSRI or SNRI, chosen by preference, availability and history.
• Panic disorder, OCD, or anxiety with depression: consider combining therapy and medication.
• A crisis that needs immediate relief: short-term options discussed with a prescriber, with a plan for the longer term.

If a treatment has had a fair trial and is not helping, signs your treatment isn't working explains what to ask for. Sometimes the right first step is different help altogether; coaching, therapy or psychiatry sorts out which kind of help fits.

If you are thinking about suicide or are in crisis, call or text 988 (the 988 Suicide & Crisis Lifeline) or go to the nearest emergency room.

The practice's anxiety care page describes its approach. Its team includes psychiatrists, psychiatric nurse practitioners and psychotherapists, and care can combine medication management, psychotherapy including CBT and DBT, and nutrition and lifestyle psychiatry. For ways to start, see the Choosing Psychiatric Care guide.

Frequently asked questions

What is the fastest-acting anxiety treatment?

Benzodiazepines and hydroxyzine act quickly, but they are generally used short-term. SSRIs, SNRIs and buspirone take weeks but are the usual long-term medication options.

Is CBT as effective as medication for anxiety?

For generalized anxiety disorder, UK guidance found no evidence that either is better and bases the choice on preference. In panic disorder and OCD, adding therapy to medication improved results, with effects lasting up to two years.

Can I take a benzodiazepine only when I need it?

Some prescribers use them occasionally for specific situations, but regular use carries risks of dependence and withdrawal. Discuss the plan, and any change to it, with your prescriber.

Is bupropion used for anxiety?

Bupropion is not FDA-approved for any anxiety disorder; its approvals are for depression and preventing seasonal depression. In depression with high anxiety, SSRIs showed a modest advantage over bupropion in pooled trials.

Are natural remedies safe to combine with my medication?

Not always. Some supplements interact with prescription medicines, and kava has been linked to severe liver injury. Check with your prescriber before adding anything.

Are benzodiazepines safe for older adults with anxiety?

The American Geriatrics Society's 2023 Beers Criteria list benzodiazepines among medications to avoid in most adults 65 and older because of risks such as falls, fractures, delirium and cognitive impairment, with a few exceptions including severe generalized anxiety disorder. If you or a parent already takes one, review it with the prescriber rather than stopping it.

Does CBD help anxiety?

The FDA has not approved cannabis or any CBD product for anxiety; its only approved CBD drug is for certain seizure disorders. Products sold with treatment claims have not had to prove them, and the FDA calls such claims illegal, so tell your prescriber if you use CBD.

How long will I need to stay on an SSRI for anxiety?

There is no fixed answer. In relapse-prevention trials, people who stopped their antidepressant relapsed more often than those who continued, so the timing and pace of any stop should be planned with your prescriber.
