PTSD is treated with a combination of talk therapy, medication, or both. The most effective first-line treatments are specific types of psychotherapy, with two FDA-approved medications available when therapy alone isn’t enough. Beyond these standard options, newer approaches like brain stimulation and ketamine infusions are showing promise for people who don’t respond to conventional care.
Trauma-Focused Psychotherapy
The treatments with the strongest evidence behind them are all forms of talk therapy that directly address the traumatic memory itself, rather than just managing symptoms around it. Three stand out.
Prolonged Exposure Therapy
Prolonged exposure works by having you gradually approach the memories, feelings, and situations you’ve been avoiding since the trauma. In sessions, you repeatedly recall and describe the details of your traumatic experience out loud. Between sessions, you listen to a recording of yourself describing those moments. The idea is straightforward: by confronting what you’ve been avoiding in a safe, controlled way, the memories lose their power over time. A standard course runs about 12 weekly one-hour sessions, though people who improve quickly can wrap up sooner, and those who need more time get additional sessions.
Cognitive Processing Therapy
Cognitive processing therapy takes a different angle. Instead of revisiting the trauma itself in vivid detail, it focuses on the beliefs that formed because of the trauma. Thoughts like “the world is completely unsafe” or “what happened was my fault” get examined through structured worksheets and critical thinking exercises. A therapist helps you evaluate whether those beliefs hold up and find more balanced ways to interpret what happened. This also typically takes 12 weekly sessions.
A VA study of more than 900 veterans compared the two head to head. Prolonged exposure was statistically more effective, but the difference wasn’t clinically meaningful. Most veterans showed significant improvement from both. The choice often comes down to personal preference: some people would rather work through the memory directly, while others prefer examining the thought patterns it created.
EMDR
Eye movement desensitization and reprocessing, or EMDR, asks you to briefly focus on a traumatic memory while simultaneously tracking a therapist’s finger moving back and forth, or following another form of rhythmic left-right stimulation like tapping or tones. This bilateral stimulation appears to lower the body’s stress response and reduce the vividness and emotional charge of the memory, allowing it to become integrated into your broader memory system rather than staying “stuck.” Treatment typically runs in weekly sessions of up to 90 minutes over about three months.
Medications
Only two medications carry FDA approval specifically for PTSD: sertraline (Zoloft) and paroxetine (Paxil). Both are SSRIs, a class of antidepressant that increases the availability of serotonin in the brain. Sertraline is typically prescribed at 50 to 200 mg daily, paroxetine at 20 to 60 mg daily. These medications can reduce the intensity of intrusive memories, hypervigilance, and emotional numbness, though they generally work best alongside therapy rather than as a standalone treatment.
Venlafaxine (Effexor), which affects both serotonin and norepinephrine, is also strongly recommended by VA and Department of Defense clinical guidelines at doses of 75 to 300 mg daily, even though it doesn’t have formal FDA approval for PTSD. It’s considered a first-line option in practice. All of these medications typically take several weeks to reach full effect, and finding the right one often involves some trial and adjustment.
Nightmares and Sleep Problems
PTSD-related nightmares are one of the most disruptive symptoms, and they don’t always respond well to standard SSRI treatment. Prazosin, a blood pressure medication, was widely prescribed for years based on smaller studies suggesting it reduced trauma-related nightmares. However, a large VA trial found that after 26 weeks, there was no statistically significant difference between prazosin and a placebo in nightmare severity or sleep distress. Some clinicians still prescribe it when other options haven’t worked, but the evidence is less convincing than once thought.
Brain Stimulation
Repetitive transcranial magnetic stimulation, or rTMS, uses magnetic pulses delivered through a device placed against the scalp to change activity levels in specific brain regions. In PTSD, certain areas involved in fear processing tend to be overactive while regions responsible for emotional regulation are underactive. High-frequency stimulation can increase activity in underactive areas, while low-frequency stimulation can dial down overactive ones. A Cochrane review found a strong positive effect on PTSD severity, with high-frequency stimulation producing larger improvements than low-frequency. Treatment requires at least five sessions, though the exact number varies. The main limitation right now is that protocols haven’t been standardized, so the stimulation target, intensity, and session count can differ significantly between providers.
Ketamine Infusions
For people with chronic PTSD who haven’t responded to standard treatments, ketamine infusions offer a notably faster timeline. In a study from Mount Sinai, 67 percent of participants receiving ketamine achieved at least a 30 percent reduction in symptom severity by week two, compared to 20 percent in the control group. Improvement was visible within 24 hours of the first infusion. Among those who responded, symptom relief lasted a median of about four weeks after the assessment period. Ketamine is not FDA-approved for PTSD specifically, and access is generally limited to specialty clinics, but it represents one of the few options that can produce rapid relief while longer-term treatments take hold.
Stellate Ganglion Block
A stellate ganglion block is an injection of local anesthetic into a cluster of nerves in the neck that controls the body’s fight-or-flight response. The theory is that it may calm overactivity in the brain’s fear center and reduce the surge of stress hormones that keeps people with PTSD in a constant state of alert. The procedure takes minutes and some patients report immediate relief. However, the strongest evidence so far is underwhelming: in a randomized controlled trial, PTSD improvement after one round of injections ranged from 5 to 15 percent, and a second round produced 12 to 21 percent improvement, which was no better than a saline placebo injection. It remains experimental, and the mechanism isn’t fully understood.
Choosing a Treatment Path
For most people, trauma-focused therapy is the place to start. The three major options, prolonged exposure, cognitive processing therapy, and EMDR, all have strong evidence and work within roughly the same timeframe of three months. If you have a strong aversion to revisiting the trauma in detail, cognitive processing therapy may feel more manageable. If you want to work through the memory head-on, prolonged exposure is designed for exactly that. EMDR offers a middle ground where you engage with the memory but in shorter, structured bursts.
Medication can be added at any point, either because therapy alone isn’t producing enough improvement or because symptoms are severe enough that medication helps you engage with therapy more effectively. The combination of psychotherapy and an SSRI is a common approach. Newer options like ketamine or brain stimulation are typically reserved for cases where first-line treatments haven’t worked, but they’re increasingly available and worth discussing with a provider if standard approaches have plateaued.
