Does EMDR Have Side Effects? What You Should Know Before Starting Therapy
If you're considering eye movement desensitization and reprocessing (EMDR) therapy, it's natural to have questions about what to expect. One concern many people have is whether EMDR has side effects. After all, EMDR is designed to help process traumatic memories, and that can sound intimidating if you've never experienced this type of therapy before.
The good news is that EMDR is a well-researched, evidence-based treatment for trauma and other distressing experiences. While it doesn't have side effects in the same way a medication might, it's common to experience temporary emotional or physical reactions as your brain processes difficult memories. Understanding these responses ahead of time can help you feel more prepared and confident as you begin your healing journey.
Why You May Notice Changes After a Session
EMDR works by helping your brain reprocess memories that may have become stuck. As those memories are processed, it's normal for thoughts, emotions, or physical sensations connected to them to shift.
Because therapy is addressing experiences that may have been avoided for a long time, it's not unusual to notice changes between sessions. These responses are often a sign that your brain is continuing to process information rather than an indication that something is wrong. Everyone's experience is different, and not everyone notices significant reactions after EMDR sessions.
Common Temporary Reactions
Some people leave an EMDR session feeling relieved, lighter, or more hopeful. Others may feel emotionally tired as their mind and body continue processing. Temporary reactions can include feeling emotionally sensitive, fatigue or low energy, vivid dreams, new memories or insights surfacing, temporary increases in emotions such as sadness or anxiety, or physical sensations connected to emotional processing.
These experiences typically lessen as processing continues and often become easier to manage over time. Your therapist will discuss what you may experience and help you understand what feels expected during treatment.
EMDR Is Designed to Be Safe
One common misconception is that EMDR requires you to relive every traumatic event in detail. In reality, treatment is carefully structured to prioritize your emotional safety. Before trauma processing begins, your therapist will spend time helping you develop coping skills, grounding techniques, and emotional regulation strategies. You'll also work together to establish trust and ensure you feel prepared before addressing distressing memories.
Throughout treatment, your therapist will regularly check in with you and adjust the pace based on your needs. Healing isn't about pushing through overwhelming emotions. It's about processing them in a way that feels manageable and supportive.
Taking Care of Yourself Between Sessions
Since emotional processing may continue after an appointment, it's helpful to plan for extra self-care. You might benefit from getting enough rest, drinking plenty of water, journaling your thoughts or feelings, spending time outdoors, practicing grounding exercises, or avoiding unnecessary stress when possible.
Many people also find it helpful to schedule quieter activities after an EMDR session rather than filling the rest of the day with demanding responsibilities. Giving yourself permission to slow down can support the healing process.
When to Talk With Your Therapist
Open communication is an important part of successful EMDR therapy. If you're feeling overwhelmed, noticing unexpected reactions, or have questions about what you're experiencing, let your therapist know. Your therapist can help you understand what's happening, adjust your treatment plan if needed, and provide additional coping strategies to support you between sessions. Remember that therapy is a collaborative process, and your comfort and well-being remain priorities throughout treatment.
Beginning EMDR With Confidence
Starting EMDR treatment can feel like a significant step, especially if you've been carrying the effects of trauma for a long time. While temporary emotional or physical reactions are possible, they're often part of your brain's natural healing process as distressing memories become less overwhelming. Understanding what to expect can make the experience feel less intimidating and help you approach treatment with greater confidence.
If you're considering EMDR therapy or wondering whether it's the right fit for you, a trained therapist can answer your questions, discuss your concerns, and help you decide on the best path toward healing and recovery.
