EMDR therapy has become one of the most effective and widely used treatments for trauma, PTSD, and distressing life experiences. As more people hear about Eye Movement Desensitization and Reprocessing (EMDR), a common question arises:

Who is EMDR not good for?

The honest answer may surprise you.

In most cases, EMDR therapy can be used safely and effectively with a wide range of individuals. Skilled EMDR therapists can modify the process, adjust the pacing, and spend more time preparing clients before beginning trauma processing.

Rather than clear “no” categories, most situations are temporary pauses, safety considerations, or readiness factors.

In other words, the majority of people who want EMDR can eventually benefit from it with the right timing and support.

This article explains the main situations therapists consider before beginning EMDR and why those factors matter.

What Is EMDR Therapy?

EMDR (Eye Movement Desensitization and Reprocessing) is a trauma therapy designed to help the brain process distressing memories that remain “stuck” in the nervous system.

During EMDR therapy, a person briefly recalls a traumatic or emotionally difficult memory while engaging in bilateral stimulation (often eye movements, tapping, or auditory cues). This process helps the brain reprocess the memory so it becomes less emotionally overwhelming.

Many people who complete EMDR therapy notice that:

Traumatic memories feel less intense
Emotional triggers decrease
Anxiety and distress become easier to manage
The memory feels like it belongs in the past rather than the present

Because EMDR is such a powerful therapy, clinicians carefully evaluate whether someone is ready for trauma processing before starting.

The Truth: EMDR Is Safe for Most People

Contrary to common misconceptions, EMDR is appropriate for most individuals.

Experienced EMDR clinicians know how to modify therapy depending on a person’s needs, resources, and life circumstances. If someone is not ready for trauma reprocessing yet, the therapist can focus on preparation, stabilization, and emotional regulation skills first.

This means the question is rarely “Can this person ever do EMDR?”

Instead, therapists ask:

“Is now the right time to begin trauma processing?”

Several factors help determine readiness.

Medical Conditions That May Require Extra Caution

Certain medical conditions do not automatically rule out EMDR therapy, but they may require collaboration with other healthcare providers.

Stroke, Seizures, or Traumatic Brain Injury

If someone has experienced a recent stroke, seizure disorder, or traumatic brain injury (TBI), therapists often consult with the client’s neurologist before beginning EMDR.

One reason is that EMDR frequently involves eye movements, which are the most common form of bilateral stimulation.

Although alternative forms of stimulation exist, therapists want to ensure that eye movements will not aggravate neurological symptoms.

A neurologist can help determine whether EMDR is medically safe for that individual.

Eye Injuries or Retinal Issues

If someone has a recent eye injury or retinal condition, therapists may request clearance from an optometrist or ophthalmologist before using eye movements in therapy.

In many cases, EMDR can still proceed using alternative bilateral stimulation, such as tapping or auditory tones.

The goal is simply to ensure therapy does not interfere with healing.

Heart Health and Pregnancy: Monitoring Emotional Activation

Some physical conditions require monitoring because EMDR can temporarily activate the nervous system.

Recent Cardiac Events

During trauma processing, emotional activation may increase heart rate and blood pressure temporarily.

For individuals who have experienced a recent cardiac event, therapists may delay EMDR until the person’s health is stable or consult with medical providers before proceeding.

Pregnancy and EMDR Therapy

Pregnancy is not a contraindication for EMDR therapy.

Many pregnant clients safely participate in EMDR. However, therapists may monitor emotional activation more closely if a client has:

High blood pressure
Pregnancy complications
A history of cardiovascular concerns

Clients who are able to regulate distress effectively between sessions typically continue EMDR without difficulty.

When Safety Must Come First: Active Suicidality

One of the clearest situations where EMDR should pause is active suicidality.

Active suicidality means someone has plans or intent to harm themselves.

In these cases, the immediate focus of therapy is safety and stabilization, not trauma processing. This may include:

Crisis intervention
Safety planning
Increased mental health support

Once safety is established and the individual is no longer actively suicidal, EMDR may become an appropriate next step.

Why Basic Needs Matter Before Trauma Therapy

Another major factor therapists consider is whether someone’s basic needs are currently being met.

If a person lacks stable housing, food security, or physical safety, the brain remains in survival mode.

When survival is the priority, trauma processing becomes extremely difficult.

In these situations, case management and resource support may be the most helpful first step. Once stability improves, therapy can shift toward deeper healing work like EMDR.

Emotional Regulation and Trauma Readiness

Before beginning EMDR trauma processing, therapists evaluate how easily a client becomes emotionally overwhelmed.

In early sessions, therapists often ask clients to briefly identify memories that may eventually be processed in therapy.

If simply referencing those memories causes extreme distress that the person cannot regulate, the therapist may spend additional time in the preparation phase.

This stage focuses on building skills such as:

Emotional regulation
Nervous system stabilization
Grounding techniques
Internal coping resources

Once these skills are established, trauma processing becomes much safer and more effective.

The Role of Support Systems in EMDR Therapy

External support also affects readiness for trauma therapy.

Clients who have strong support systems like friends, family, or community often have additional help regulating emotions between therapy sessions.

If someone has very limited support outside therapy, clinicians may spend more time strengthening internal resources before beginning EMDR.

This helps ensure the client can manage emotional processing safely between sessions.

Dual Awareness: A Core Requirement for EMDR

A central concept in EMDR therapy is dual awareness.

Dual awareness means the ability to hold two realities at once:

The awareness that you are safe in the present moment
The awareness that you are remembering something from the past

This ability allows a person to process traumatic memories without becoming overwhelmed.

Certain conditions can interfere with this capacity.

Active Psychosis

Individuals experiencing active psychosis may struggle with distinguishing past from present reality.

In these cases, stabilization of symptoms typically occurs before trauma processing begins.

Active Intoxication or Substance Use

EMDR requires a person to stay oriented to the present moment during memory processing.

If someone is actively intoxicated, it becomes difficult to maintain the focus and awareness needed for EMDR.

Therapists generally require sobriety during sessions.

Long-Term Amphetamine Use

Long-term stimulant use may affect emotional regulation and cognitive functioning, which can make dual awareness difficult.

Stabilization of substance use often improves readiness for trauma therapy.

Cognitive Ability and EMDR Therapy

In some cases, intellectual disabilities may affect a person’s ability to maintain dual awareness.

When cognitive functioning is significantly limited, therapists evaluate whether the individual can understand the difference between past memories and present safety.

If that distinction is difficult to maintain, other therapeutic approaches may be more appropriate.

Medications That May Affect EMDR Progress

Certain medications can influence the pace of EMDR therapy.

One example is benzodiazepines, which are often prescribed for anxiety.

These medications reduce emotional activation, which can sometimes slow the trauma processing process. EMDR relies on some emotional engagement with the memory in order to reprocess it.

However, taking these medications does not necessarily prevent EMDR from working.

Therapists may collaborate with prescribing providers to determine the best approach while therapy continues.

Legal Cases and Trauma Therapy

Another factor many people do not consider involves ongoing legal cases.

If someone is involved in a legal proceeding related to trauma, such as an assault, and plans to testify in court, EMDR therapy may change how they emotionally respond to the memory.

EMDR often reduces emotional intensity associated with traumatic memories. While this is helpful therapeutically, a calmer emotional response may sometimes be misunderstood in legal settings.

For this reason, therapists may encourage clients to discuss the timing of EMDR therapy with their attorney if a legal case is ongoing.

The Bottom Line: EMDR Is Rarely a “No”

When people ask who EMDR therapy is not good for, the real answer is that very few situations permanently prevent someone from doing EMDR.

Most concerns are temporary factors that require:

Additional preparation
Medical consultation
Stabilization of symptoms
Collaboration with other providers

With proper guidance from a trained EMDR therapist, many people who initially appear uncertain candidates can still benefit from trauma reprocessing later.

EMDR is not just about revisiting painful memories—it is about helping the brain process them in a way that reduces distress and restores a sense of safety.

Frequently Asked Questions About EMDR Therapy

Is EMDR therapy safe?

Yes. EMDR therapy is considered a safe and evidence-based treatment for trauma and PTSD when conducted by a trained clinician. Therapists assess readiness and stability before beginning trauma processing.

Who should not do EMDR therapy?

EMDR may be temporarily delayed for individuals who are experiencing active suicidality, active psychosis, severe instability in basic needs, or medical conditions that require provider consultation. In most cases, these are temporary pauses rather than permanent restrictions.

Can people with anxiety or depression do EMDR?

Yes. EMDR therapy is commonly used to treat anxiety, depression, trauma, PTSD, and distressing life experiences.

Can EMDR make symptoms worse?

Some people may experience temporary emotional activation while processing memories. A trained EMDR therapist helps clients regulate these responses and ensures the process remains manageable.

Can you do EMDR while taking medication?

Yes. Many people complete EMDR therapy while taking medications. However, some medications, such as benzodiazepines, may slow emotional processing.

How do I know if I’m ready for EMDR?

A trained therapist will help determine readiness by assessing emotional regulation skills, safety, support systems, and stability in daily life.
