Quick Answer: Anxiety disorders are the most common mental health conditions in the U.S.: NIMH estimates 19.1% of adults had one in the past year and 31.1% will at some point. Everyday worry is normal; a disorder involves anxiety that is excessive, persistent and interferes with daily life. The treatments with the strongest evidence are psychotherapy, especially cognitive behavioral therapy (CBT), and medication, most often SSRIs or SNRIs; many people use both. Benzodiazepines work quickly but carry an FDA boxed warning about misuse, dependence and withdrawal. Regular exercise, good sleep and limiting caffeine and alcohol help, and the U.S. Preventive Services Task Force recommends anxiety screening for adults 64 and younger. If you are in crisis, call or text 988.
Anxiety Management at a Glance
| Approach | Evidence base | Time to help | Notes |
|---|---|---|---|
| Cognitive behavioral therapy (CBT) | Strong; first-line (NIMH) | Weeks to months; typically structured course | Skills persist after therapy ends |
| SSRIs / SNRIs | Strong; first-line medications | Often several weeks for full effect | Daily; taper with prescriber when stopping |
| Buspirone | Approved for generalized anxiety | Weeks | Not habit-forming; less useful for panic |
| Benzodiazepines | Effective short term | Within hours | FDA boxed warning: misuse, dependence, withdrawal |
| Exercise, sleep, less caffeine/alcohol | Supportive | Days to weeks | Helpful add-ons; not a substitute for treatment of a disorder |
| Supplements (e.g., chamomile, lavender) | Limited or mixed (NCCIH) | Varies | Kava linked to severe liver injury |

Everyday Anxiety vs an Anxiety Disorder
Anxiety is a normal response to stress; it sharpens focus before a deadline or a hard conversation. NIMH describes anxiety disorders as different: the worry or fear doesn’t go away, can get worse over time, and interferes with work, school and relationships. The main types are generalized anxiety disorder (persistent, hard-to-control worry about many things), panic disorder (recurrent unexpected panic attacks), social anxiety disorder, specific phobias, and separation anxiety.
Common physical signs include restlessness, fatigue, trouble concentrating, irritability, muscle tension, sleep problems, a racing heart and shortness of breath. Some medical issues, such as an overactive thyroid, heart rhythm problems, and stimulant or caffeine use, can produce similar symptoms, so a medical check is a sensible first step.
How Common Anxiety Is
NIMH’s figures from the National Comorbidity Survey Replication estimate that 19.1% of U.S. adults had an anxiety disorder in the past year, with higher rates in women (23.4%) than men (14.3%), and that 31.1% of adults experience one at some point. Among adolescents aged 13 to 18, NIMH reports a lifetime prevalence of 31.9%. Because these conditions are so common and often go unrecognized, the U.S. Preventive Services Task Force (USPSTF) in 2023 recommended screening adults aged 64 and younger for anxiety, including during pregnancy and after birth.
Psychotherapy
NIMH identifies psychotherapy, and CBT in particular, as an effective treatment for anxiety disorders. CBT teaches you to notice anxious thought patterns, test them against evidence, and gradually face feared situations instead of avoiding them. Exposure therapy, a CBT component, is especially useful for phobias, panic and social anxiety. Acceptance and commitment therapy (ACT) focuses on making room for uncomfortable feelings while acting on your values. CBT is typically a structured course of sessions, and the skills you learn can keep working after therapy ends. See CBT vs DBT and therapy vs medication for anxiety.
Medication
- SSRIs and SNRIs (for example escitalopram, sertraline, paroxetine, venlafaxine, duloxetine) are the most commonly prescribed first-line medicines. NIMH notes they can take several weeks to reach full effect and side effects such as nausea, sleep changes or sexual side effects are possible. Antidepressants carry an FDA boxed warning about suicidal thoughts in children, teens and young adults, so close follow-up is important when starting.
- Buspirone is approved for generalized anxiety disorder and is not habit-forming.
- Benzodiazepines (such as alprazolam, lorazepam, clonazepam) relieve anxiety quickly. In 2020 the FDA required a boxed warning covering abuse, misuse, addiction, physical dependence and withdrawal reactions, and warned about the danger of combining them with opioids. They are generally reserved for short-term or specific use.
- Beta-blockers such as propranolol are sometimes used off-label for physical symptoms of performance anxiety.
Never stop an antidepressant or benzodiazepine suddenly; tapering with your prescriber reduces withdrawal effects.
Self-Care That Helps
- Move regularly. NIMH lists exercise among self-care strategies that can reduce stress and improve mood.
- Protect sleep. Poor sleep and anxiety feed each other; see our sleep hygiene guide.
- Limit caffeine and alcohol. Caffeine can trigger jitteriness and a racing heart; alcohol can rebound into worse anxiety and poorer sleep.
- Slow breathing and relaxation. Paced breathing, progressive muscle relaxation and mindfulness meditation are low-risk skills; NCCIH notes meditation and mindfulness practices may help with anxiety symptoms. See meditation vs medication for stress.
- Reduce avoidance. Small, planned steps toward situations you avoid shrink anxiety over time, the same principle exposure therapy uses.
- Stay connected. Talking to people you trust and joining a support group can help.
What About Supplements?
NCCIH, the federal agency that studies complementary health approaches, says that for most herbs and supplements studied for anxiety, the evidence is limited or inconsistent. Some, such as chamomile and lavender preparations, have shown modest effects in small studies. The clearest warning is for kava: NCCIH notes it has been linked to severe liver damage, and the FDA issued a consumer advisory about this risk in 2002. Supplements can also interact with prescription medicines; St. John’s wort, for example, interacts with many drugs including SSRIs. For details on individual products, see our supplements for anxiety guide, L-theanine vs GABA and ashwagandha vs rhodiola, and tell your clinician about anything you take.
How to Get Started
A primary care clinician is a good first stop: they can rule out medical causes, screen with a short questionnaire, start medication if appropriate, and refer you to therapy. If cost is a barrier, community mental health centers, employee assistance programs and university training clinics often offer lower-cost care. The Substance Abuse and Mental Health Services Administration runs FindTreatment.gov to locate services.
When to Talk to Your Doctor or Pharmacist
See a clinician if anxiety is frequent, hard to control, or interfering with work, school, relationships or sleep; if you have panic attacks; if you are avoiding places or activities; or if you use alcohol or drugs to cope. If you are thinking about harming yourself or are in crisis, call or text 988 (Suicide & Crisis Lifeline, U.S.) or call 911. Chest pain or trouble breathing should be treated as a medical emergency until a heart or lung cause is ruled out.
Frequently Asked Questions
What is the fastest way to calm anxiety?
Slow, paced breathing and grounding techniques can ease acute anxiety within minutes. They manage symptoms in the moment; therapy and, where appropriate, medication address an ongoing disorder.
Is CBT or medication better for anxiety?
Both are effective, first-line options per NIMH, and many people use both. CBT skills tend to last after treatment ends; medication can help faster for some people. The right choice depends on severity, preference and access.
How long do SSRIs take to work for anxiety?
NIMH notes antidepressants can take several weeks to reach their full effect. Don’t stop early or suddenly without talking to your prescriber.
Are benzodiazepines safe?
They work quickly but carry an FDA boxed warning about misuse, addiction, physical dependence and withdrawal, and are dangerous with opioids. They are usually used short term under close supervision.
Do supplements help anxiety?
NCCIH says evidence for most supplements is limited. Kava has been linked to serious liver injury. Check with a clinician or pharmacist before combining supplements with medication.
