Living with post-traumatic stress disorder can mean feeling as though your nervous system is still responding to danger long after the traumatic event has ended. Intrusive memories, nightmares, avoidance, emotional disconnection, irritability, and hypervigilance can affect relationships, sleep, work, and the ability to feel safe in everyday life.
Evidence-based psychotherapy and medication help many people with PTSD. However, treatment does not produce complete relief for everyone. Some patients improve only partially. Others have difficulty tolerating a particular therapy, cannot access a trained provider, experience medication side effects, or find that co-occurring depression, anxiety, chronic pain, or dissociation complicates recovery.
At Thrive Center for Health in Grand Rapids, we work with patients whose symptoms have remained disruptive despite previous care. We do not view a difficult treatment history as proof that recovery is impossible. We see it as a reason to reassess what has been tried, clarify what is still happening, and discuss the limits as well as the potential benefits of any additional option.
Understanding How PTSD Can Affect Daily Life
PTSD can develop after experiencing or witnessing trauma. It is more than remembering something painful. The condition can affect how a person responds to reminders, interprets potential danger, regulates emotion, sleeps, concentrates, and connects with other people.
Symptoms generally fall into several areas:
- Intrusive memories, nightmares, or flashbacks
- Avoidance of thoughts, feelings, places, or conversations associated with the trauma
- Changes in mood, beliefs, memory, or emotional connection
- Hypervigilance, irritability, sleep disruption, or an exaggerated startle response
Some people also experience dissociation. This may involve feeling detached from the body, emotions, surroundings, or sense of identity. It can be brief and subtle or significantly disruptive.
Our article on PTSD-related dissociation describes how these experiences may appear in daily life. Dissociation can also affect treatment planning, particularly when a therapy or medication may temporarily alter perception or awareness.
PTSD symptoms vary widely. Two people with the same diagnosis may have different trauma histories, triggers, co-occurring conditions, strengths, and treatment needs. That is why we begin with the individual rather than assuming that one protocol will fit every patient.
Which PTSD Treatments Have the Strongest Evidence?
Current clinical guidelines recommend individual, manualized trauma-focused psychotherapy as the primary treatment for PTSD when it is available and acceptable to the patient.
The approaches with the strongest support include:
- Cognitive Processing Therapy
- Eye Movement Desensitization and Reprocessing
- Prolonged Exposure
These treatments use different methods, but each helps patients process trauma-related memories, beliefs, emotions, or avoidance patterns within a structured therapeutic framework.
Medication may also have a role. Current guidelines support sertraline, paroxetine, and venlafaxine as medication options for PTSD. The choice depends on symptoms, previous responses, side effects, other diagnoses, medical history, and patient preferences.
These therapies and medications should not be dismissed simply because they are considered conventional. They remain the most established treatments for PTSD and should generally be discussed before less-studied interventions.
Our approach to PTSD treatment in Grand Rapids recognizes the value of established care while also acknowledging that some patients continue to experience significant symptoms.
When Therapy Has Helped, but Symptoms Remain
Reaching the limits of one therapy does not necessarily mean that all psychotherapy has failed.
A treatment may have been difficult to access consistently. The therapeutic relationship may not have felt safe enough for trauma work. The approach may not have matched the patient’s symptoms or preferences. Treatment may also have ended before an adequate course was completed.
In other cases, a patient may have completed an appropriate course of care and still experience nightmares, avoidance, hyperarousal, depression, or difficulty functioning.
When this happens, the next step may involve:
- Reviewing whether the original diagnosis still fits
- Considering a different evidence-based trauma therapy
- Adjusting the pace or delivery format
- Addressing depression, anxiety, sleep problems, pain, or substance use
- Reviewing medication response and side effects
- Strengthening stabilization and coping skills
- Coordinating care among multiple providers
- Exploring a specialized intervention when clinically appropriate
We do not want patients to interpret an incomplete response as a personal failure. PTSD treatment can require more than one approach, and progress is not always linear. Understanding when acute stress becomes PTSD can also help clarify whether a diagnosis still fits the current clinical picture.
Why We Reassess Before Discussing Ketamine
Ketamine treatment should not be recommended from a diagnosis alone.
Before discussing candidacy, we want to understand the full course of your symptoms. This includes the nature of the trauma, current PTSD symptoms, previous therapy, medication history, dissociation, sleep, substance use, medical conditions, safety concerns, and any co-occurring diagnoses.
At Thrive, our ketamine therapy screening process includes separate psychiatric and medical evaluations. These steps help us clarify the condition being targeted and identify factors that may affect safety or treatment planning.
We also consider whether another form of established PTSD care remains available. Ketamine should not be presented as a shortcut around evidence-based trauma therapy or as proof that conventional treatment has nothing more to offer.
For some patients, the appropriate next step may be medication management, a different psychotherapy approach, or stronger coordination with an existing therapist. For others, an individualized discussion of IV ketamine may be reasonable after the benefits, uncertainties, and alternatives have been reviewed.
What the Research Says About IV Ketamine for PTSD
Ketamine affects NMDA receptors and glutamate signaling. Because these pathways are involved in learning, memory, and synaptic function, researchers have studied whether ketamine may reduce PTSD symptoms or make trauma-related patterns more responsive to further treatment.
Small randomized trials have reported relatively rapid reductions in PTSD symptom severity after a single infusion or a short series of infusions. These findings have created legitimate scientific interest.
However, the evidence is not settled.
The studies have generally involved small groups, short follow-up periods, varying trauma histories, and different treatment schedules. Some evidence reviews have found promising short-term effects, but questions remain about durability, maintenance, patient selection, and the balance between benefit and risk.
The 2023 Department of Veterans Affairs and Department of Defense clinical guideline issued a weak recommendation against using ketamine to treat PTSD. The guideline cited very low confidence in the evidence and concluded that the available data did not establish a favorable enough risk-benefit balance for routine PTSD treatment.
We believe patients deserve to know that.
The recommendation does not erase the encouraging findings from early trials or prevent clinicians from considering the full needs of an individual patient. It does mean that IV ketamine should not be described as an established first-line PTSD therapy, a replacement for trauma-focused psychotherapy, or a treatment with predictable results.
IV ketamine for PTSD is an off-label use. It has not been approved specifically for PTSD, and individual outcomes vary. Our overview of what ketamine infusion therapy is provides broader context on how this treatment is used and monitored.
How Co-Occurring Depression May Affect the Conversation
PTSD frequently occurs alongside depression. In some cases, depressive symptoms become as disruptive as the trauma symptoms themselves.
When a patient has both PTSD and difficult-to-treat depression, we clarify which symptoms are being targeted and what the evidence supports for each condition. A treatment that improves depression does not necessarily resolve avoidance, flashbacks, nightmares, or other core PTSD symptoms.
This distinction matters when evaluating progress. We do not want a change in one symptom area to be interpreted as proof that the entire condition has been treated.
We may use validated symptom measures, clinical interviews, and the patient’s description of daily functioning to monitor changes over time. We also communicate with outside providers when the patient authorizes coordination and collaboration would support safer, more consistent care.
Addressing Concerns About Dissociation
Some people with PTSD worry that ketamine’s perceptual or dissociative effects could feel destabilizing. That concern should be taken seriously.
During ketamine treatment, a patient may temporarily experience changes in awareness, body perception, time, visual imagery, or the sense of connection to the environment. These effects are not identical to trauma-related dissociation, but they may feel uncomfortable or familiar to someone who already struggles with detachment or loss of control.
A history of dissociation does not automatically qualify or disqualify a patient. It does mean we need to understand:
- How dissociation currently presents
- Whether it is associated with panic, memory loss, or safety concerns
- Which situations tend to trigger it
- How well the patient can use grounding strategies
- Whether a trusted therapeutic relationship is already in place
- What level of support may be needed before, during, and after treatment
We explain potential experiences before treatment rather than expecting patients to manage an altered state without preparation. A patient should also feel able to tell us that a particular approach does not feel right.
How Ketamine-Assisted Psychotherapy Differs
We also offer ketamine-assisted psychotherapy, commonly called KAP. This approach combines ketamine treatment with psychotherapeutic preparation, therapist support, and integration.
Preparation may involve discussing goals, concerns, boundaries, grounding strategies, and what would help the patient feel supported. A therapist is present during the medicine session, and integration provides time to reflect afterward.
You can learn more about our ketamine-assisted psychotherapy service and our explanation of how KAP works.
KAP should not be portrayed as an established replacement for Cognitive Processing Therapy, EMDR, Prolonged Exposure, or another evidence-based PTSD treatment. Research combining ketamine and psychotherapy is still developing, and studies use widely different therapy models, medication routes, schedules, and patient populations.
Current evidence does not allow us to say that KAP is consistently more effective than a standard infusion or that it will make trauma processing easier for every patient.
For some people, the structure and therapist presence may feel supportive. For others, discussing trauma-related material during or soon after an altered state may not be appropriate. We consider stability, readiness, therapy history, dissociation, goals, and personal preference before recommending this format.
What Happens During a Standard IV Infusion?
During a standard IV infusion, ketamine is administered through a vein while our clinical team monitors the patient.
The session focuses on the medication treatment rather than structured psychotherapy. Patients may listen to music, wear an eye covering, rest quietly, or communicate with our team when needed.
Temporary effects can include:
- Changes in perception
- A dreamlike or detached feeling
- Dizziness
- Nausea
- Anxiety
- Changes in blood pressure or heart rate
The patient remains under observation and must arrange transportation home. Driving after treatment is not permitted.
Our guide to what to expect during a first ketamine infusion explains preparation, monitoring, recovery, and transportation in greater detail.
The subjective experience is not the only outcome we monitor. A session can feel meaningful without producing durable clinical improvement, and an unusual experience does not necessarily indicate that treatment is working.
We look for measurable changes in symptoms, functioning, sleep, relationships, and the ability to participate in ongoing care.
We Support Continuity With Your Existing Care Team
Beginning care at Thrive does not automatically mean ending treatment with your current therapist, psychiatrist, or primary care provider.
PTSD often requires continuity, trust, and coordination. A clinician who already understands your trauma history may remain an important part of your care even when we provide a specialized service.
With your permission, we may communicate with existing providers about:
- Current diagnoses and treatment goals
- Medication management
- Changes in symptoms
- Safety concerns
- Timing of therapy around ketamine sessions
- Support between appointments
- The plan if symptoms worsen
We do not advise patients to stop medication or abandon trauma-focused treatment simply because ketamine is being considered. Any medication change should be discussed with the prescribing provider.
Practical Barriers Are Part of the Treatment Decision
Cost, scheduling, transportation, work obligations, and access to therapy can all affect whether a plan is realistic.
We discuss these concerns directly. We want patients to understand the expected appointment structure and current financial responsibility before committing to treatment.
Insurance coverage varies by service and plan. Because policies and billing arrangements can change, patients should confirm current details with our team and their insurer rather than relying on a general statement in a blog.
A treatment plan is not truly individualized when it ignores the patient’s ability to attend appointments, arrange transportation, maintain outside care, or manage the expense.

Frequently Asked Questions
When should someone consider additional options for PTSD?
Additional options may be worth discussing when symptoms remain significantly disruptive after an adequate course of evidence-based care, when side effects limit medication use, or when another condition is complicating treatment. The first step should be reassessment. A clinician may recommend a different trauma-focused therapy, medication management, treatment for a co-occurring condition, or another specialized intervention.
Is IV ketamine an established treatment for PTSD?
No. IV ketamine for PTSD is an off-label use, and current evidence is limited. Small trials have reported short-term improvements, but the studies are not large or consistent enough to establish ketamine as routine PTSD care. The current VA/DoD guideline weakly recommends against ketamine for treating PTSD. We discuss these limitations openly when evaluating whether ketamine may be appropriate in an individual clinical situation.
Can ketamine help with flashbacks or nightmares?
Some studies measured changes across overall PTSD symptoms, which may include intrusion symptoms such as distressing memories and nightmares. However, the available evidence does not allow us to predict which symptom clusters will improve for a particular patient. A reduction in depression or general distress should not automatically be interpreted as resolution of trauma-related symptoms.
Is KAP the same as trauma-focused psychotherapy?
No. KAP combines ketamine with preparation, therapist support, and integration, but it is not automatically equivalent to an established trauma-focused treatment such as Cognitive Processing Therapy, EMDR, or Prolonged Exposure. A patient may receive KAP alongside other mental health care, but the role of each treatment should be clearly defined.
Can someone with dissociative symptoms receive ketamine?
Possibly, but careful evaluation is essential. We review the type and severity of dissociation, triggers, stability, coping skills, medical history, and other safety factors. For some patients, dissociative or perceptual effects may be difficult to tolerate, and another approach may be more appropriate.
Can someone with both PTSD and depression be evaluated?
Yes. We evaluate patients with co-occurring diagnoses, including PTSD and depression. We still clarify which condition is being targeted, how each diagnosis affects candidacy, and how improvement will be measured. The presence of multiple diagnoses does not automatically mean ketamine is appropriate.
What should I do if PTSD symptoms feel dangerous right now?
A consultation or future treatment appointment is not a substitute for emergency support. Call or text 988 if you are experiencing suicidal thoughts or an emotional crisis. Call 911 or go to the nearest emergency department if you may act on those thoughts, cannot remain safe, or believe there is an immediate danger to you or someone else.

When You Need a More Individualized Conversation
When PTSD symptoms remain after therapy or medication, it can feel as though every available path has already been tried. Often, the most responsible next step is not to rush toward a new treatment. It is to take a closer look at what has and has not happened so far.
At Thrive Center for Health, we review your treatment history, current symptoms, dissociation, medical needs, co-occurring conditions, and goals before discussing any recommendation. Depending on what we learn, the next step may involve medication management, coordination with your therapist, a different evidence-based PTSD treatment, IV ketamine, KAP, or another care pathway.
We will explain the evidence honestly, including the limitations and current guideline concerns surrounding ketamine for PTSD. We do not promise that one intervention will resolve a complex trauma history.
What we can offer is a thoughtful evaluation, a respectful environment, and a clinical conversation centered on your needs rather than a one-size-fits-all treatment pitch.
