Key Takeaways
Adults with social anxiety disorder who responded to an SSRI vs. a placebo pill (24 trials, 4,984 participants)
Response meant a clinician rating of much or very much improved after acute treatment: about 523 per 1,000 on SSRIs versus 317 per 1,000 on placebo. Cochrane reviewers rated the certainty of this evidence as very low.
"We found evidence of treatment efficacy for the SSRIs"
Therapy Options Beyond Individual CBT
Group CBT, exposure with social skills training, and guided self-help all beat a waitlist in the 2014 analysis, with SMDs of 0.92, 0.86 and 0.86[1]. Self-help without therapist support (0.75) and psychodynamic psychotherapy (0.62) had smaller effects[1].
Exposure therapy, a CBT method, works by progressively confronting the situations a person avoids, and NIMH notes that group CBT can offer unique benefits for social anxiety disorder[6]. Acceptance and commitment therapy (ACT) uses mindfulness and goal setting, and NIMH describes a growing body of research supporting it for this condition[6]. The ACT therapists explainer covers how that approach works.
Support groups are a complement rather than a substitute. NIMH says members can offer honest feedback about how others perceive them, while cautioning that peer advice does not replace a provider's treatment recommendations[6]. Therapy for anxiety compares these approaches across other anxiety disorders.
Response vs. remission
In social anxiety disorder trials, response usually means a clinician rated the person much or very much improved on the Clinical Global Impression–Improvement (CGI-I) scale[2]. Remission is stricter: in the 2010 combined-treatment trial it meant a CGI score of 1, and symptom severity was tracked on the Liebowitz Social Anxiety Scale[3].

Is Combining Therapy and Medication Better?
One direct test is a 2010 placebo-controlled trial of 128 adults that compared cognitive behavioral group therapy (CBGT), the MAO inhibitor phenelzine, their combination and pill placebo[3]. At week 24, 78.1% of the combined group had responded, compared with 52.9% on CBGT, 48.6% on phenelzine and 33.3% on placebo[3].
Remission showed a wider gap: 53.1% with combined treatment versus 23.5% for CBGT and 25.7% for phenelzine at week 24[3]. The authors concluded that combined treatment was superior to either treatment alone and to placebo[3].
That result comes from one trial using group rather than individual CBT and an MAO inhibitor rather than an SSRI, so it does not show that every therapy-plus-SSRI pairing adds benefit. NIMH frames the choice between psychotherapy, medication or both as one based on a person's needs, preferences and medical situation[6].
Response and Remission at Week 24 in a Combined-Treatment Trial
| Treatment arm | Participants | Response | Remission |
|---|---|---|---|
| Pill placebo | 27 | 33.3% | 14.8% |
| Group CBT (CBGT) | 34 | 52.9% | 23.5% |
| Phenelzine | 35 | 48.6% | 25.7% |
| CBGT plus phenelzine | 32 | 78.1% | 53.1% |

How Long Does Treatment Take, and What Happens After Stopping?
Antidepressants for social anxiety may take several weeks to start working, and NIMH notes that finding the best treatment may take trial and error[6].
Among people who had responded, staying on an SSRI was associated with fewer relapses than switching to placebo: about 135 versus 397 per 1,000, in 3 trials with 389 participants[2]. SSRIs were the only medication with moderate-quality evidence for reducing relapse in the Cochrane review[2].
A 2017 BMJ meta-analysis of 28 relapse-prevention trials (5,233 patients) across anxiety disorders, OCD and PTSD found relapse rates of 36.4% after switching to placebo versus 16.4% on continued antidepressants, over follow-up of up to one year[4]. Subgroup analyses, including by type of disorder, found no significant differences, and the authors wrote that the lack of data beyond one year should not be read as advice to stop at that point[4].

Social Anxiety Disorder Medication Classes vs. Placebo
Risk ratio for treatment response versus placebo in adults with social anxiety disorder, acute-phase randomized trials, 2017 Cochrane review[2]
1A risk ratio above 1 means more people responded on the drug than on placebo. The beta-blocker confidence interval (0.63 to 1.88) includes 1, so no effect was shown.
2Response means a rating of much or very much improved on the Clinical Global Impression scale.
