EMDR safety: preparation, risks and when to pause
Safety in EMDR cannot be reduced to one universal list of contraindications. It depends on individual assessment, sufficient preparation, shared goals, tolerable pacing and a clear plan for responding to deterioration or risk.
Safe practice assesses stability, risk, dissociation, health, medication, support, privacy and the ability to close a session. Temporary activation can occur, but intense or persistent distress, loss of functioning or risk warrants reviewing or pausing the plan.
Preparation is clinical, not ceremonial
Before processing begins, the therapist needs to understand relevant history, the current context and what happens between appointments. Preparation may include psychoeducation, stop signals, regulation resources, closure practice and a plan for seeking help.
There is no fixed amount of preparation that suits everyone. Too little may increase risk, while indefinite preparation without goals or review also deserves questions. The criteria for moving forward should be explained.
Risk, dissociation and co-occurring conditions
Marked dissociation, suicidal thoughts, psychosis, problematic substance use, pregnancy, brain injury, medication or medical problems cannot be managed by one rule. They may require specialist assessment, coordination, adaptation, a different treatment priority or a pause.
EMDR should not be used to recover or verify memories. Responsible practitioners avoid suggesting events, distinguish emotional intensity from historical accuracy and explain limitations when legal or forensic implications exist.
Online, intensive and after-session care
Online delivery requires privacy, physical location, a backup contact, local resources and a plan for connection failure. Intensive formats require clarity about duration, breaks, assessment, support between blocks and follow-up.
Tiredness, dreams or emotions may occur after a session. You should know what may be expected, how closure works and when to make contact. If there is immediate danger, urgent local help takes priority over continuing any processing exercise.

Questions to orient your next step
Can EMDR make symptoms worse?
Temporary activation or distress can occur. Intense or persistent deterioration, impaired functioning, disconnection or risk requires professional contact and review of the plan.
Does dissociation rule out EMDR?
There is no universal answer. It requires assessment, relevant expertise, preparation and possible adaptation; another intervention or stabilisation may need to take priority in some situations.
Is EMDR safe by video call?
It can be offered online after suitability is assessed. Privacy, location, a backup contact, interruption planning and emergency resources where the client is located should be agreed.
