4 EMDR Contraindications and How Clinicians Prepare
EMDR is not appropriate to start right away for a few clearly defined situations: unmanaged dissociative identity disorder or severe dissociation, an active psychotic episode or uncontrolled manic/mixed bipolar episode, active substance dependence, and living in an ongoing unsafe or abusive environment. Nearly everything else, including complex trauma, mild dissociation, and eating disorder history, is a precaution that a trained clinician can prepare for rather than a permanent exclusion. If you identify with these situations, consult a licensed therapist or physician before beginning trauma processing.
TL;DR:
EMDR is contraindicated in unmanaged dissociative identity disorder, active psychosis, uncontrolled bipolar episodes, active substance dependence, and ongoing unsafe living situations, requiring stabilization first.
Most other conditions, such as complex trauma or mild dissociation, just need careful preparation and stabilization before starting reprocessing.
Medical conditions like epilepsy, recent brain injury, or eye issues often require a switch to tactile or auditory bilateral stimulation instead of visual eye movements.
Medications like benzodiazepines or active substance use may blunt processing, but should not be stopped without medical advice; stability is key.
Short-term reactions to EMDR are usually mild, but worsening symptoms or seizure activity require immediate professional intervention.

Understanding EMDR Contraindications and Why Timing Matters
The EMDR contraindications list that clinicians actually work from is shorter than most people expect, and it has less to do with whether EMDR "works" for you than with whether your nervous system and living situation can handle it right now. Eye Movement Desensitization and Reprocessing is built to activate distressing memories quickly, sometimes within the first session, so it works differently than talk therapy that lets you approach a memory slowly and on your own terms.
That speed is the whole point of the treatment, and also the reason it isn't a fit for everyone on day one. The World Health Organization and the American Psychological Association both list EMDR among their recommended treatments for post-traumatic stress, which tells you the modality itself is not in question. What's in question is readiness. A person in active crisis, actively using substances to cope, or currently unsafe at home doesn't have the internal or external stability to process a traumatic memory without it destabilizing them further. That's the core distinction this entire guide is built around: most EMDR precautions are about sequencing, not disqualification.
When EMDR Is Usually Not Appropriate Yet
Certain severe conditions represent genuine contraindications where beginning EMDR without stabilization can worsen symptoms.
Unmanaged dissociative identity disorder or severe dissociation. When someone switches between distinct identity states or loses co-consciousness during sessions, standard EMDR protocols can trigger further fragmentation instead of integration. EMDR training materials call for extensive Phase 2 stabilization and specialized dissociation training before any reprocessing begins with this population, and that groundwork can take months, not sessions.
Active psychosis or an uncontrolled manic or mixed bipolar episode. Reprocessing depends on a person being able to distinguish between a memory and present reality. During active psychosis, that reality testing is already compromised, and bilateral stimulation can add confusion rather than clarity. A manic or mixed episode carries its own risk: the mood instability itself can escalate under the emotional intensity EMDR sessions tend to produce.
Active substance dependence. If someone is actively using to manage cravings or withdrawal, they typically don't have the coping bandwidth EMDR requires between sessions. Processing a traumatic memory and then going home to an unmanaged relapse risk is a bad combination; stabilizing the substance use usually comes first.
A currently unsafe or abusive living situation. This one gets underestimated. If the threat that caused the trauma is still happening (an abusive partner, an unsafe home) reprocessing that specific trauma while it's ongoing can worsen day-to-day functioning instead of resolving anything. Safety planning has to happen before the memory work does.
These four are the closest things to a hard stop in EMDR, and even they are usually temporary. A clinician's job in each case is to build stability first and revisit reprocessing once that foundation exists.
Presentations That Usually Just Need More Preparation
Most of what people search for under "EMDR contraindications" actually falls into this category: not exclusion, just a longer runway before the memory-processing phases begin.
Complex developmental trauma. People with early, repeated relational trauma often need extended work in Phase 2, the resourcing and stabilization phase, before reprocessing starts. That can mean building internal resources, repairing attachment ruptures, and developing distress tolerance skills over several sessions rather than one or two.
Mild to moderate dissociation. This calls for careful assessment and slower pacing, not a blanket ban. A clinician trained to screen for dissociation can often work with it directly by shortening sets and checking in more frequently.
Active self-harm or an active eating disorder. These require a documented safety plan and, often, coordination with a specialist (a dietitian, a psychiatrist) before trauma processing begins. The goal is making sure a person has stable coping tools in place before opening up material that might spike distress.
High-dose benzodiazepine use. This is a conversation for the prescribing doctor, not a decision to make solo. Abruptly stopping a benzodiazepine to "qualify" for EMDR is genuinely dangerous and should never be attempted without medical supervision.
Anyone dealing with complex trauma usually benefits from a longer preparation phase, and that extra time is an investment in the reprocessing going well, not a sign that something is wrong with the approach.
Pro Tip: If you're on any psychiatric medication, bring the exact dosage and prescriber information to your first EMDR consultation. It saves a session of back-and-forth and lets your therapist coordinate care from day one.
Physical and Neurological Conditions That Need Medical Coordination
Certain medical conditions for EMDR require a conversation with a physician before the standard protocol starts, mostly because of how bilateral stimulation is delivered.
Photosensitive epilepsy. Rhythmic visual stimulation, the classic side-to-side eye movement, can trigger seizures in people with this condition. Harvard Health notes that recent traumatic brain injury, stroke, and retinal eye conditions carry similar physical-health concerns tied to visual BLS.
Recent TBI or stroke. Cognitive tolerance for rapid emotional activation may be reduced during recovery, so clinicians often slow the pace and check functioning more closely before pushing into reprocessing.
Retinal or other ocular conditions. Anyone with an eye condition that makes tracking movement uncomfortable or medically inadvisable is a candidate for a modified protocol.
The fix for most of these isn't avoidance. It's substitution. Tactile bilateral stimulation (alternating hand taps or buzzers) and auditory bilateral stimulation (alternating tones through headphones) deliver the same left-right neural activation without the visual component, preserving the protocol while removing the physical risk. A responsible clinician will ask about seizure history, recent head injury, and eye conditions at intake and loop in a physician for clearance when anything is unclear.
How Medications and Active Substance Use Change the Picture
Medication doesn't automatically disqualify anyone from EMDR, but certain classes change how the treatment works and need to be discussed openly with your therapist and prescriber.
Benzodiazepines and other heavy sedatives. These can blunt the emotional activation EMDR depends on, which sometimes reduces how well the processing generalizes to daily life. This isn't a reason to stop taking a prescribed medication. It's a reason to flag it so your clinician can adjust pacing and expectations.
Active intoxication or withdrawal. Either state raises the risk of destabilization during a session, so most clinicians will postpone reprocessing until the person is medically stable.
Medication-assisted recovery. Being on a stabilized MAT program (methadone, buprenorphine) is not, by itself, a reason to exclude someone from EMDR. Documented stability matters more than the medication itself.
The one rule that applies across every scenario here: never stop or taper a psychiatric medication on your own to become "eligible" for EMDR. That decision belongs to the prescriber, and a good therapist will insist on that coordination before moving forward.
Side Effects, Adverse Events, and When to Call Your Therapist
Most people tolerate EMDR without lasting problems, but the honest answer about negative effects of EMDR is that the research on this is thinner than you'd hope.
Short-term reactions are common and usually mild: vivid or unsettling dreams, headaches, fatigue, dizziness, and a temporary spike in emotional intensity that fades within a few days, according to Harvard Health.
The evidence gap is real. A systematic review of 51 randomized controlled trials found that only nine even mentioned adverse effects, and just one used a systematic method to track them. Where harms were reported, they tended to be mild and temporary, but the review's authors flagged the inconsistency itself as a problem worth fixing, not just a footnote.
Watch for red flags that go beyond normal processing discomfort: functional impairment that doesn't lift after a day or two, new or worsening suicidal ideation, or any seizure activity. Any of those warrants an immediate call to your therapist or a medical provider, not a wait-and-see approach. Responsible practice includes pacing sessions to avoid overwhelming a client, teaching grounding techniques to use between appointments, and keeping a documented crisis plan on file before deep reprocessing begins.
What Screening and Stabilization Actually Look Like
A clinician who takes EMDR patient suitability seriously will run through a structured process before ever picking up the tapper or starting eye movements.
Intake screening. This includes a dissociation screen, a safety and suicidality check, substance use history, and a review of medical history including seizures, neurological events, and current medications.
Stabilization work. Depending on what intake reveals, this might mean resource installation (building internal calming imagery), grounding practice, distress tolerance skills, and a written safety plan.
Protocol adaptation. For clients with medical or sensory limitations, that means switching to tactile or auditory BLS, shortening processing sets, and slowing the overall pace.
Ongoing reassessment. Stabilization isn't a one-time checkbox. Clinicians revisit readiness throughout treatment and defer reprocessing further if new instability shows up.
If you're evaluating a therapist, it's fair to ask directly about their EMDR training level, their experience with dissociation, and how they coordinate with your other providers. Precautions for EMDR therapy work best when they're addressed openly, not glossed over in a first phone call. Reading through a step-by-step preparation guide before your first session gives you a clearer sense of what that intake conversation should actually cover.
Pro Tip: Ask your therapist how they'd adapt the protocol if a session brought up more than expected. Their answer tells you more about their training than any credential on a website.
How Alvaradotherapy Approaches Screening in Practice
Some trauma-informed therapists build intake around the same phase-based model outlined above: a full screening for dissociation, safety, and medical history, followed by stabilization work before reprocessing starts, as detailed in the CVPSD comprehensive trauma-informed care training suite. Trauma-informed care can include bilingual services and coordination with outside medical providers when physical or neurological concerns need clearance first. If you're unsure whether EMDR is right for your situation, a consultation is the most reliable way to get an individualized answer rather than guessing from a checklist. You can also review what EMDR sessions actually involve before booking.
