Frequently asked questions
Is medically supervised ketamine therapy safe?+
Sub-anesthetic ketamine has a well-characterized safety profile when administered by qualified clinicians with vitals monitoring, screening for cardiovascular and psychiatric risk, and trained staff present throughout the session. Safety degrades sharply outside that frame.
Who should NOT receive ketamine?+
Uncontrolled hypertension, unstable cardiovascular disease, active psychosis, recent stroke, severe liver disease, untreated bipolar disorder with manic features, pregnancy (relative), and active substance use disorders are common contraindications or strong cautions.
What are the most common side effects?+
Transient blood pressure and heart rate elevation, nausea, dissociation, dizziness, blurred vision, and post-session fatigue. Most resolve within 1-2 hours of session end.
Can ketamine therapy cause bladder problems?+
Long-term high-dose recreational use is linked to ulcerative cystitis ("K-bladder"). Therapeutic doses given intermittently in clinical settings have not shown this risk in published cohorts. Report any urinary urgency, frequency, or pain to your prescriber immediately.
Is there a risk of addiction?+
Therapeutic-dose ketamine under clinical supervision has low addiction risk. Risk rises with at-home/unsupervised use, escalating dosing patterns, and personal or family history of substance use disorder. Honest monitoring is essential.
Will I lose control during a session?+
You'll remain breathing on your own, with intact reflexes. You may feel mentally detached or have unusual perceptions. You won't be unconscious, and staff can communicate with you throughout. Anesthetic-dose ketamine — a different scenario — is not what therapeutic clinics use.
What about ketamine and suicidal thoughts?+
Ketamine has been studied specifically for rapid reduction of acute suicidal ideation, with several positive trials. It does not replace crisis-level safety planning, hospitalization when appropriate, or ongoing therapy.
Can I drive after a session?+
No. Plan to have someone drive you home, and don't drive, operate machinery, or sign legal documents for at least 12-24 hours post-session, per your clinic's protocol.
What monitoring should a clinic do during a session?+
Blood pressure and pulse at baseline and every 10-15 minutes, pulse oximetry, a trained staff member present or immediately available, emergency medications and equipment on site, and post-session recovery before discharge.
When should I call the clinic after a session?+
Persistent confusion or dissociation beyond a few hours, chest pain, severe headache, sustained nausea/vomiting, urinary symptoms, new severe mood changes, or any thought of self-harm.
