How to Treat PTSD: Why Therapy Comes First and Where Medication Fits

Maybe it’s the nightmares, or the way a slammed door still sends your heart racing. Maybe you’ve quietly stopped going places that remind you of what happened. If you’re living with the aftermath of trauma, the question underneath it all is simple: what actually helps?

After trauma, reminders can set off the same alarm the original event did, long after the danger is gone. The treatments with the most evidence are trauma-focused, which a 2018 treatment review by Watkins and colleagues defines as therapies that directly address memories of the event or the thoughts and feelings tied to it. Matching the right one to your symptoms takes precision.

Antidepressants are a well-established option for PTSD, and they do help. In a 51-trial meta-analysis, SSRIs reduced PTSD symptoms more than placebo, though the effect was small. That benefit is real, and it’s well documented.

But medication alone is no longer the strongest first step for most people, and at Siggy we’d rather help you understand every option than default to the one that’s easiest to prescribe.

The 2023 VA/DoD guideline now recommends specific trauma-focused therapies, such as cognitive processing therapy (CPT), prolonged exposure (PE), and EMDR, over medication as first-line treatment. Medication still plays a role, especially when depression or anxiety come along with PTSD. The order matters because of what head-to-head trials show, and that ranking comes straight from the evidence.

What Is the Best First Treatment for PTSD?

Trauma-focused psychotherapy is the recommended starting point. The 2023 VA/DoD guideline recommends specific manualized therapies over medication and names PE, CPT, and EMDR among its recommended options. It also supports secure video delivery when a therapy has been validated for video or other options aren’t available.

The research behind that ranking is broad. A 114-trial systematic review by Lewis and colleagues, with 8,171 participants, found robust evidence that trauma-focused cognitive behavioral therapy and EMDR have a clinically important effect, with CPT, cognitive therapy, and PE showing the strongest evidence. It also found some evidence for guided internet-based CBT and group trauma-focused CBT, which can widen access when one-on-one therapy is hard to find.

Durability is part of the case too. In a network meta-analysis of 12 trials comparing approaches directly, no treatment was clearly better at the end of treatment, but psychotherapy showed greater benefit than medication at the last follow-up. The authors note that long-term data are scarce, so this is an area still being studied.

How Do CPT, PE, and EMDR Compare?

All three are structured, time-limited, and effective. They differ mainly in how they approach the trauma.

Therapy	What It Focuses On	Key Evidence
Cognitive processing therapy	Challenging stuck beliefs about the trauma	Strongest evidence tier, 114-trial review
Prolonged exposure	Revisiting the memory and avoided situations	Slightly larger gains than CPT, 916 veterans
EMDR	Memory processing with guided eye movements	Clinically important effect, 114-trial review
Written exposure therapy	Writing about the trauma over 5 sessions	Matched CPT with fewer dropouts

The descriptions of CPT and PE come from the Watkins review of guideline-recommended therapies, and the evidence column draws on the 114-trial Lewis review and the trials described below.

The biggest head-to-head comparison is a VA trial of 916 veterans at 17 medical centers. Both PE and CPT produced substantial improvement. PE came out slightly ahead, but the authors judged the difference too small to matter clinically and emphasized choosing together based on preference.

If you’re curious about EMDR specifically, our guide to EMDR therapy for PTSD explains how a session works.

What If Talking About the Trauma Feels Impossible?

That fear is common, and staying in trauma therapy can be hard. In the VA trial, 56% of people assigned to PE and 47% assigned to CPT stopped before finishing.

Shorter options can help. In a noninferiority trial of 126 adults, written exposure therapy, which uses five sessions of writing about the trauma, worked as well as 12 sessions of CPT. Only 6% of people dropped out of written exposure therapy, compared with 40% of those in CPT.

The Watkins review also notes that the current CPT protocol no longer requires a written trauma account and focuses instead on the beliefs that keep you stuck. If one approach feels like too much, a trauma-trained therapist can help you find one that doesn’t.

Where Does Medication Fit in PTSD Treatment?

Medication is a supporting player with real value. The VA/DoD guideline recommends paroxetine, sertraline, or venlafaxine for PTSD. These are antidepressants, and their benefit is modest: in the 51-trial meta-analysis, SSRIs as a group beat placebo by a small margin. Looking at individual drugs, the authors found small but significant benefits for two SSRIs, fluoxetine and paroxetine, and for venlafaxine, an SNRI. For most other drugs, they found the evidence inadequate.

Medication can make sense when therapy isn’t available or isn’t your preference, and it may help when depression or anxiety make therapy hard to start. In the network meta-analysis, combining medication with therapy didn’t outperform therapy alone at long-term follow-up.

Some common medications aren’t a good fit. The guideline recommends against benzodiazepines and cannabis for PTSD.

Prazosin, a medication studied for trauma-related nightmares, has mixed evidence. In a 26-week trial of 304 veterans, it didn’t reduce distressing dreams or improve sleep compared with placebo. But a 2020 meta-analysis of eight trials found that prazosin did improve nightmares overall, even though it wasn’t better than placebo for PTSD symptoms as a whole. If nightmares are a major problem, it’s worth discussing with your prescriber as a sleep-focused option rather than a treatment for PTSD itself.

Why Does Treating Depression Alongside PTSD Matter?

PTSD rarely travels alone. In a 57-study meta-analysis, 52% of people with current PTSD also had major depression, and rates were higher in military samples and after interpersonal trauma. The authors concluded that depression should be routinely assessed in anyone with PTSD.

A national U.S. survey of 36,309 adults found PTSD was strongly linked with mood, anxiety, and substance use disorders, as well as disability. PTSD was also more common among women, younger adults, people with lower incomes, and rural residents. Our guide to PTSD and anxiety explains how the two overlap.

How Long Does PTSD Treatment Take?

Most evidence-based therapies are short by design. CPT typically runs 12 weekly sessions, PE usually takes 8 to 15, and written exposure therapy uses 5, according to the Watkins review and the written exposure trial.

Getting started is often the longest step. In the national survey, 6.1% of adults had PTSD at some point in their lives, 59.4% of them sought treatment, and an average of 4.5 years passed between onset and first treatment. If you’ve been carrying this for years, you’re far from the only one, and it’s not too late to start.

How Siggy Fits In

Many people describe the same frustration: “I have to retell my story every time I see someone new.” Having your history in one place matters when you’re dealing with something as personal as trauma.

Siggy starts with a free, anonymous intake, with no name or email required. A licensed prescriber reviews your intake before anything is prescribed, and you get a summary you can keep and share with any clinician, including a trauma therapist. Siggy’s licensed prescribers diagnose and treat the full range of mental health conditions, including PTSD and complex PTSD. A prescriber can talk with you about whether a guideline-recommended medication like sertraline fits, for PTSD itself or for depression or anxiety that come along with it.

Since trauma-focused therapy is the first-line treatment, medication isn’t the whole answer. Siggy combines human clinicians with AI therapy and daily check-ins that support the work between visits, and a specialist trained in CPT, PE, or EMDR can be part of your plan.

The Bottom Line on Treating PTSD

The strongest first step for most people with PTSD is a trauma-focused therapy like CPT, PE, or EMDR, and shorter options such as written exposure therapy make that step more reachable. Medications like sertraline, paroxetine, and venlafaxine help modestly and can be a good fit when therapy isn’t available or isn’t your preference, or when depression or anxiety come along with PTSD. Benzodiazepines and cannabis aren’t recommended. If you’re still sorting out what you’re dealing with, our guide to complex PTSD vs. PTSD can help.
