Understanding Ketamine Therapy Side Effects

Learn ketamine therapy side effects, including common and serious risks, safe use guidance, informed recovery, and its role in mental health treatment.
Ketamine therapy is emerging as a promising option for individuals struggling with depression, PTSD, and other mental health challenges. While it offers hope when other treatments have failed, it’s essential to understand the potential ketamine therapy side effects before starting.
If you or someone you care about is considering this treatment, knowing what to expect can help you make informed, confident decisions. At The Edge Treatment Center, we believe in supporting your recovery with clarity, compassion, and care, ensuring every step you take toward healing is backed by safe, personalized treatment.
What Is Ketamine Therapy?

Ketamine therapy is a promising treatment approach for mental health and addiction issues when used safely under medical supervision.
Medical Use Vs. Recreational Use
Ketamine therapy involves the use of low, medically supervised doses of ketamine to treat conditions like depression, PTSD, anxiety, and addiction.
Unlike recreational ketamine use—which can be dangerous, unpredictable, and illegal—therapeutic use is structured, controlled, and evidence-based.
Recreational use often leads to misuse and adverse effects, while clinical ketamine therapy focuses on healing and recovery.
Ketamine-Assisted Psychotherapy (KAP) and Infusion Therapy
There are two primary forms of ketamine therapy: Ketamine-Assisted Psychotherapy (KAP) and IV or IM infusion therapy. In KAP, ketamine is combined with talk therapy during or after the session to deepen emotional processing.
In infusion therapy, ketamine is administered in low doses through an IV or intramuscular injection under clinical supervision. Both approaches aim to improve mood, disrupt negative thought patterns, and support emotional breakthroughs.
Common and Short‑Term Side Effects
When beginning ketamine therapy, many people experience temporary, manageable side effects. These can include:
Dissociation (feeling detached from your body or surroundings)
Dizziness or lightheadedness
Nausea or vomiting
Headache
Blurred vision
Increased heart rate or blood pressure
These effects typically occur during or shortly after your session and wear off within a few hours. While they can be uncomfortable, they are not dangerous when monitored by medical professionals.
Physical Discomfort
Some individuals may also notice mild physical effects, such as fatigue or slight irritation at the injection site. These are usually short-lived and can be easily managed by our clinical team at The Edge Treatment Center.

Less Common & Transient Psychological Effects
In some cases, patients may experience less common psychological effects, including:
Hallucinations or vivid dreams
Feelings of anxiety or panic during the session
Mild confusion or emotional intensity
These reactions are typically brief and tend to become less frequent with continued treatment. At The Edge, we provide a calm, supportive environment to help you feel safe during these moments.
Rare Mental Reactions
Rare psychological responses—such as mood swings, paranoia, or brief episodes of delirium—can occur but are uncommon in a structured clinical setting. Our trained staff is always present to support you and intervene if needed.
Rare but Serious & Long‑Term Risks
While rare, some serious side effects have been observed, especially with high doses or prolonged use outside medical supervision. These include:
Respiratory depression
Allergic reactions
Heart rhythm abnormalities (arrhythmia)
These risks are extremely uncommon when ketamine is used responsibly under medical supervision, as we do at The Edge Treatment Center.
Long-Term Physical Health Risks
With long-term or frequent use, patients may face risks such as:
Bladder inflammation (cystitis) or bladder damage
Liver toxicity in rare cases
We proactively minimize these risks through careful dosing and regular health evaluations.
Tolerance and Dependence
Although ketamine is not considered physically addictive like opioids, repeated use can lead to tolerance or psychological dependence. We address this by providing comprehensive mental health care alongside treatment, ensuring you're supported every step of the way.

Risk Factors & Who Should Exercise Caution

While ketamine therapy can offer powerful relief, certain medical and psychological conditions require special consideration before beginning treatment.
Medical Conditions That Require Extra Care
While ketamine therapy can be highly effective, it may not be suitable for everyone. Individuals with certain pre-existing medical conditions should be carefully evaluated before beginning treatment. These include:
Hypertension (high blood pressure)
Cardiovascular disease
Liver conditions
Bladder disorders or a history of urinary tract issues
At The Edge Treatment Center, we conduct a thorough medical assessment before starting ketamine therapy to ensure it’s safe for you. If any of these conditions are present, we may adjust the treatment plan or explore alternative options for your recovery.
Mental Health and Substance Use History
Ketamine therapy may also pose risks for those with a history of psychotic disorders, such as schizophrenia, as it can potentially trigger or worsen psychotic symptoms.
Similarly, individuals with past or current substance misuse issues need careful screening, as ketamine does have the potential for psychological dependence if misused.
We take a personalized, cautious approach to treatment and work closely with you to make sure it supports—not complicates—your recovery.
Why Supervision Matters
Unsupervised or at-home use of ketamine—especially without professional guidance—can increase the risk of serious side effects, dependence, and medical complications.
At The Edge Treatment Center, every ketamine therapy session is supervised by trained professionals in a controlled, therapeutic environment. This ensures your safety while maximizing the benefits of treatment.
Your well-being is always our priority, and that starts with making sure ketamine therapy is the right and safest option for your unique needs.
