    Anxiety treatments guide: CBT, SSRIs, SNRIs and what NICE advises

    Guidelines put talking therapy, mainly cognitive behavioural therapy (CBT), and SSRI antidepressants at the centre of anxiety treatment.[1][2] For generalized anxiety disorder, NICE says the choice between high-intensity therapy and medication should follow the person's preference, because neither has been shown to be better.[3] Benzodiazepines work quickly but carry dependence risks; NICE and WHO advise against routine use.[4][5][6]

    Anxiety disorders respond to treatment, and the main options have been tested in many randomised trials.[7][8] This guide sets out what the UK’s National Institute for Health and Care Excellence (NICE), WHO, NIMH and the NHS recommend, and what the trial evidence shows. Medicine names and session numbers come from the guidelines and trials named, in the populations they studied.

    This page is general information, not medical advice. Do not start, stop or change a treatment without talking to a clinician.

    How care is organised: stepped care

    NICE recommends “stepped care” for generalized anxiety disorder: start with the least intrusive treatment that works, and step up if needed.[9] After an assessment, education and monitoring, the first treatments are low-intensity: self-help based on CBT, guided self-help with a practitioner, or group courses.[10] If those do not help, or the anxiety is seriously affecting daily life, the next step is either one-to-one therapy or medicine.[3] In the UK the NHS says a GP will usually suggest talking therapy before medicine, and adults in England can refer themselves to NHS talking therapies.[11][12]

    NICE CG113 step 3 applies to GAD with marked functional impairment or an inadequate response to step 2. It offers either an individual high-intensity psychological intervention or drug treatment, chosen by preference because there is no evidence either mode is better.[3] For panic disorder, NICE recommends CBT totalling 7 to 14 hours, usually in weekly sessions completed within 4 months.[13] For social anxiety disorder, a separate guideline (CG159) recommends individual CBT built specifically for social anxiety, based on the Clark and Wells or Heimberg models, over group CBT.[14]

    Talking therapies

    Cognitive behavioural therapy helps people notice and question inaccurate or harmful automatic thoughts and change the behaviour patterns that keep anxiety going.[15] WHO says CBT-based therapies, including exposure therapy, have the most evidence across anxiety disorders.[1] For GAD, NICE recommends CBT or applied relaxation, usually 12 to 15 weekly one-hour sessions with a trained practitioner.[16]

    EvidenceWhat it found
    2018 meta-analysis, 41 placebo-controlled trialsModerate overall effect of CBT; large for GAD and OCD, smaller for panic disorder and social anxiety[7]
    Same meta-analysisExposure-based treatments had larger effects than cognitive techniques, though not significantly[17]
    TAME trial, 276 adults (2022)An 8-week mindfulness-based stress reduction course was noninferior to escitalopram[18]

    NIMH also lists acceptance and commitment therapy (ACT), which uses mindfulness and goal setting, as an option for GAD with a growing evidence base.[19] For panic disorder, interoceptive exposure deliberately brings on the bodily sensations of panic so that people learn to react to them differently.[20] NICE does not recommend routinely offering mindfulness-based interventions for social anxiety disorder.[21] For an overview of other talking therapies, see types of therapy explained; for depression, see the depression treatments guide.

    Medicines

    The medicines used most for anxiety are antidepressants called SSRIs and SNRIs. They can take several weeks to work and may cause side effects such as headaches, nausea or trouble sleeping.[22] The NHS says many side effects ease after a couple of weeks.[23] It is not common, but some people have suicidal thoughts when they start an antidepressant; the NHS says people aged 24 or under may be most at risk and should speak to a doctor straight away if this happens.[24] The NHS also says not to stop an antidepressant suddenly without talking to a doctor.[25]

    NICE CG113 recommends an SSRI for GAD when drug treatment is chosen, considering sertraline first on cost-effectiveness grounds, then an alternative SSRI or an SNRI.[2] Pregabalin may be considered if SSRIs and SNRIs are not tolerated; it has been a Class C controlled drug in the UK since April 2019.[26] For social anxiety disorder, CG159 names escitalopram or sertraline.[27] A 2019 Lancet network meta-analysis of 89 trials in adult GAD outpatients found duloxetine, pregabalin, venlafaxine and escitalopram effective with relatively good acceptability.[8] Quetiapine had the largest effect but was poorly tolerated, as were paroxetine and benzodiazepines.[28] NIMH notes that buspirone, a non-sedating option, takes 3 to 4 weeks to be fully effective.[29]

    Benzodiazepines: fast but discouraged

    Benzodiazepines can reduce anxiety quickly, but some people build tolerance or become dependent, so NIMH says they may be prescribed only briefly.[29] In 2020 the FDA required updated boxed warnings for the whole class, covering abuse, addiction, physical dependence and withdrawal.[6] The FDA says dependence can develop within days to weeks of steady use, even as prescribed, and that stopping abruptly can cause withdrawal reactions including seizures.[30]

    NICE says not to offer a benzodiazepine for GAD except as a short-term measure during a crisis, and not to prescribe one for panic disorder.[4][31] WHO generally does not recommend them for anxiety disorders.[5]

    Digital and new treatments

    WHO says CBT-based help can also be delivered online and through apps.[32] In September 2024 the FDA cleared DaylightRx, a prescription CBT app from Big Health, as the first digital treatment for GAD, for adults aged 22 and older alongside usual care.[33] General wellness apps are a different category; see the meditation apps buyer’s guide.

    New drugs are in late-stage trials. In 2026 Definium Therapeutics reported positive results from two phase 3 trials of a single dose of DT120, an LSD-based tablet, in GAD.[34][35] It is not approved, and the company has said it expects to file for approval in the first half of 2027.[36] The anxiety research and policy tracker follows these developments.

    Questions readers ask

    What is the first treatment for generalized anxiety disorder?

    NICE uses stepped care, starting with the least intrusive effective option. After education and monitoring, it recommends low-intensity help such as guided self-help or psychoeducational groups. The NHS says a GP will usually suggest talking therapy before medicine.[9][10][11]

    Is CBT or medication better for anxiety?

    For GAD that needs high-intensity treatment, NICE says to base the choice on the person's preference because there is no evidence that either CBT or drug treatment is better. NIMH notes many people benefit from a combination.[3][37]

    Which medicine does NICE suggest first for GAD?

    NICE recommends an SSRI, considering sertraline first because it is the most cost-effective. If sertraline does not work, NICE suggests another SSRI or an SNRI. Any prescribing decision is for a clinician.[2]

    How long do SSRIs take to work for anxiety?

    NIMH says SSRIs and SNRIs may take several weeks to start working. They can cause side effects such as headaches, nausea or difficulty sleeping.[22]

    Why are benzodiazepines not recommended for anxiety?

    WHO says they carry a high potential for dependence and have limited long-term effectiveness. The FDA warns that physical dependence can develop within days to weeks, even as prescribed. NICE says to use them for GAD only as a short-term measure in a crisis, and not for panic disorder.[5][30][4][31]

    Can I stop my antidepressant if I feel better?

    The NHS says not to stop an antidepressant suddenly or without talking to your doctor, who can plan a gradual reduction.[25]

    Is there an FDA-cleared app for anxiety?

    Yes. In September 2024 the FDA cleared Big Health's DaylightRx, a prescription app that delivers CBT, as the first digital treatment for generalized anxiety disorder, for adults 22 and older alongside usual care.[33]
