What is the recommended treatment for anxiety, depression, and post‑traumatic stress disorder (PTSD) in adults?

Treatment for Anxiety, Depression, and PTSD in Adults

For PTSD specifically, start with manualized trauma-focused psychotherapy—specifically prolonged exposure, cognitive processing therapy, or eye movement desensitization and reprocessing (EMDR)—as these are strongly recommended over medications as first-line treatment. 1

PTSD Treatment Algorithm

First-Line: Trauma-Focused Psychotherapy (Strong Recommendation)

The 2023 VA/DoD guideline provides the most authoritative current evidence and strongly recommends specific manualized psychotherapies over pharmacotherapy 1. The three psychotherapies with the strongest evidence are:

• Prolonged Exposure (PE) - Involves repeated, detailed recounting of the trauma memory and gradual confrontation of avoided situations 1, 2, 3
• Cognitive Processing Therapy (CPT) - Addresses maladaptive beliefs about the trauma 1, 2
• Eye Movement Desensitization and Reprocessing (EMDR) - Uses bilateral stimulation during trauma processing 1, 2, 4

These three therapies demonstrate clinically important effect sizes and sustained benefits at follow-up 2, 4. Network meta-analyses show EMDR (SMD -2.07) and trauma-focused CBT (SMD -1.46) produce the largest symptom reductions compared to waitlist 4.

Delivery format: These therapies can be delivered via secure video teleconferencing when validated for that format or when in-person options are unavailable 1.

Second-Line: Pharmacotherapy (When Psychotherapy Unavailable or Patient Preference)

If psychotherapy is not accessible or the patient prefers medication, use:

• Paroxetine, sertraline, or venlafaxine - These are the only medications with strong recommendations 1
• SSRIs (fluoxetine, paroxetine, sertraline) and the SNRI venlafaxine have conditional recommendations from multiple guidelines 1, 5, 6

Critical Contraindications (Strong Recommendations Against)

Never prescribe benzodiazepines, cannabis, or cannabis-derived products for PTSD treatment 1. This is a strong recommendation based on lack of efficacy and potential harm.

Depression Treatment

For major depressive disorder, the 2016 ACP guideline shows no significant difference between second-generation antidepressants (SGAs) and cognitive behavioral therapy (CBT) for response or remission 7. This means:

• Start with either CBT or an SGA (fluoxetine, paroxetine, sertraline, escitalopram, citalopram) based on patient preference and availability 7
• Moderate-quality evidence shows equivalent efficacy after 8-52 weeks 7
• Combination therapy (SGA + CBT) shows no clear advantage over monotherapy for most outcomes 7

Anxiety Disorders

For generalized anxiety and other anxiety disorders:

• First-line: SSRIs or SNRIs (sertraline, paroxetine, escitalopram, venlafaxine) 5
• First-line psychotherapy: Cognitive-behavioral therapy 5
• Pregabalin (calcium channel modulator) is also first-line 5
• Benzodiazepines reserved only for treatment-resistant cases without substance abuse history 5

Comorbid Presentations (Common Clinical Reality)

PTSD + Depression

When both conditions coexist, prioritize PTSD treatment first. CPT, prolonged exposure, NET, and mindfulness/body-focused therapies show beneficial effects on both PTSD and co-occurring depression symptoms 8. SSRIs/SNRIs address both conditions simultaneously if using pharmacotherapy 9, 5.

PTSD + Anxiety

These conditions share neurobiological features and respond to similar treatments 9. SSRIs/SNRIs are effective for both 9, 5. Trauma-focused psychotherapy for PTSD often improves anxiety symptoms as well.

PTSD + Borderline Personality Disorder

Use Dialectical Behavior Therapy adapted for PTSD (DBT-for-PTSD) over standard CPT, as it shows superior effects on borderline symptoms (MD -0.58) 8.

Complex PTSD

For C-PTSD presentations, skills training approaches show promise and should be incorporated before or alongside trauma-focused work 8.

Critical Pitfalls to Avoid

1. Do not use benzodiazepines for PTSD - Strong evidence against this practice 1
2. Do not avoid trauma-focused therapy due to complexity - Evidence shows trauma-focused therapies with or without exposure are equally effective (SMD 0.02, no difference) 8, so concerns about exposure causing harm are unfounded
3. Address sleep disruption - Treat sleep apnea with CPAP, nightmares, and insomnia (preferably with psychotherapy) as this improves PTSD and mood symptoms 9
4. Do not use present-centered therapy for PTSD with depression - Weak recommendation against this approach 8

Practical Implementation

Start with trauma-focused psychotherapy (PE, CPT, or EMDR) for PTSD. If the patient has significant depression or anxiety alongside PTSD, these psychotherapies will likely improve all three conditions. If psychotherapy is not immediately available, initiate paroxetine, sertraline, or venlafaxine while arranging psychotherapy access. For pure depression without trauma history, either CBT or an SSRI is appropriate based on patient preference. For pure anxiety disorders, start with an SSRI/SNRI or CBT.

The evidence strongly favors psychotherapy over medication for PTSD specifically, but both are reasonable for depression and anxiety disorders 1, 7, 5.
