When someone survives a car crash, combat, assault, or any life-threatening event, their brain doesn’t always reset. For about 1 in 10 people, the fear doesn’t fade. It lingers in flashbacks, nightmares, and a constant sense of danger-even when they’re safe. This is post-traumatic stress disorder, or PTSD. It’s not weakness. It’s a biological response to overwhelming trauma. And treating it isn’t about popping a pill and hoping for the best. It’s about understanding how the brain stores trauma, and how medication and therapy can help untangle it.

What PTSD Really Feels Like

PTSD isn’t just feeling sad or anxious after something bad happens. It’s four things happening at once: intrusive memories, avoidance, negative thoughts, and being on high alert all the time. You might relive the event in vivid flashbacks. You might avoid places, people, or even conversations that remind you of it. You might feel numb, guilty, or like the world is unsafe-even if nothing bad has happened in years. And you might jump at every loud noise, sleep poorly, or feel irritable for no reason.

The DSM-5-TR, the official guide doctors use to diagnose PTSD, says these symptoms must last more than a month and mess up your job, relationships, or daily life. That’s the threshold. Not everyone who experiences trauma gets PTSD. But for those who do, it’s not something they can just “get over.”

Why Therapy Is the First Step

Most experts agree: trauma-focused therapy should come before medication. Why? Because medication can ease symptoms, but it doesn’t process the trauma. Therapy does.

Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) are the two most proven methods. In CPT, you work with a therapist to challenge the thoughts that got stuck after the trauma-like “It was my fault” or “The world is completely dangerous.” You don’t erase the memory. You change how it controls you.

Prolonged Exposure is more direct. You slowly, safely, revisit the trauma in your mind, over and over, in sessions. At first, it’s terrifying. But over time, the fear loses its power. The memory becomes just a memory-not a live threat.

Studies show 60-70% of people who finish these therapies reach full remission. That’s better than any drug. And the effects last. After therapy ends, symptoms don’t usually come back-unless new trauma hits.

What Medications Actually Do

Only two drugs are FDA-approved specifically for PTSD: sertraline (Zoloft) and paroxetine (Paxil). Both are SSRIs-selective serotonin reuptake inhibitors. They don’t cure PTSD. They help you feel calm enough to do the hard work of therapy.

Sertraline works for about 53% of people. Paroxetine helps 60%. That means nearly half don’t respond. And even when they do, only 20-30% get completely symptom-free. The rest still struggle with sleep, irritability, or emotional numbness.

Other medications are used off-label because they help some people. Venlafaxine (Effexor XR), an SNRI, works just as well as SSRIs in many studies. Mirtazapine and amitriptyline show modest benefits, especially for sleep and nightmares. But they come with side effects: weight gain, drowsiness, dry mouth.

Then there’s prazosin. It’s not an antidepressant. It’s a blood pressure drug. But for veterans and others with trauma-related nightmares, it’s a game-changer. In VA studies, half the users cut their nightmare frequency in half within four weeks. No other medication does that.

Antipsychotics like risperidone and quetiapine? They’re sometimes added for severe hyperarousal-when you’re constantly tense, angry, or paranoid. But the evidence is shaky. They help a little, but the risks (weight gain, tremors, diabetes) are real.

Medication vs. Therapy: The Numbers Don’t Lie

Let’s compare them side by side.

PTSD Treatment Comparison: Therapy vs. Medication

Factor	Trauma-Focused Therapy	SSRIs (Sertraline/Paroxetine)
Time to see results	8-12 weeks	4-6 weeks
Response rate	60-70%	50-60%
Remission rate	60-70%	20-30%
Side effects	Mild discomfort during exposure	Nausea, insomnia, sexual dysfunction, emotional blunting
Long-term benefit	Yes-effects last after treatment ends	No-relapse is common after stopping
Cost (per month)	$100-$200 per session	$4-$10 (generic)

Therapy costs more upfront. But it’s a one-time investment. Medication is cheaper per month-but you might need it for years. And even then, you’re not healing. You’re managing.

The Real Problem: Side Effects and Dropout

Here’s what no one tells you: nearly one in three people quit SSRIs because of side effects. Sexual dysfunction hits hard-35% lose libido. 28% can’t reach orgasm. Emotional blunting is another silent killer. Some patients say they feel like a zombie-no joy, no sadness, just flat. They stop taking the pill because they don’t feel like themselves.

On Reddit’s r/ptsd community, 42% of users who tried SSRIs stopped because of these issues. That’s not failure. That’s a system mismatch. These drugs aren’t designed for trauma. They’re designed for depression. And trauma isn’t depression.

That’s why prazosin is so important. It doesn’t touch mood. It doesn’t dull emotions. It just quiets the nightmares. For someone who can’t sleep because they’re reliving an assault or a firefight, that’s not a bonus. It’s survival.

When Medication Makes Sense

Therapy isn’t for everyone. Some people are too overwhelmed to start. Others live in constant danger-domestic violence, active combat, unstable housing. In those cases, medication can be a bridge.

If you’re too anxious to leave your house, SSRIs might help you get to therapy. If nightmares are destroying your sleep, prazosin might give you enough rest to even think about healing.

The VA and DoD guidelines say: try therapy first. But if it’s not possible, or if symptoms are too severe, start medication. And if therapy doesn’t work after 8-12 sessions, add medication.

Combining both? That’s where the biggest gains happen. A 2021 JAMA Psychiatry study found 72% of people improved when they got sertraline and prolonged exposure together-better than either alone.

What’s Coming Next

The future of PTSD treatment is already here. MDMA-assisted psychotherapy, once considered experimental, just got FDA Breakthrough Therapy designation. In phase III trials, 67% of participants no longer met PTSD criteria after three sessions with MDMA and therapy. That’s not a miracle. It’s science.

Brexpiprazole, an antipsychotic, is being reviewed by the FDA to add to SSRIs for stubborn cases. Early results show a 35% symptom drop when added to existing meds.

And then there’s genetics. Researchers have found 95 genetic markers linked to how people respond to SSRIs. In five years, we might test your DNA before prescribing a drug-so you don’t waste months on something that won’t work.

What You Can Do Right Now

If you think you have PTSD:

• Start with therapy. Look for a provider trained in CPT or PE. The VA offers it for free to veterans. Many nonprofits offer sliding-scale rates.
• If therapy feels impossible, talk to your doctor about prazosin for nightmares or an SSRI for overall anxiety.
• Don’t give up if the first drug doesn’t work. Try another. Sertraline, paroxetine, venlafaxine-each affects people differently.
• Track your symptoms. Use a journal or the VA’s PTSD Coach app. Small improvements matter.
• Be honest about side effects. Sexual dysfunction? Nausea? Emotional numbness? Tell your doctor. There are alternatives.

PTSD isn’t a life sentence. It’s a wound that needs the right kind of care. Medication can quiet the noise. But only therapy can help you hear yourself again.
