A Well-Studied Medicine

Ketamine has been used in medicine since 1970 and is on the World Health Organization's List of Essential Medicines. Originally developed as an anesthetic, it has one of the widest safety margins of any anesthetic agent. At the low, subanesthetic doses used for mental health and pain treatment, the safety profile is well-established.

  • Over 60 years of clinical use across anesthesia, emergency medicine, and psychiatry
  • WHO List of Essential Medicines—used worldwide in hospitals and clinics
  • Subanesthetic doses (10-25% of anesthetic levels) used for therapy
  • Does not suppress breathing at therapeutic doses (unlike opioids)
  • Wide therapeutic index—large margin between effective and dangerous doses

Common Side Effects

Most side effects are mild, temporary, and resolve within a few hours of your session. Understanding what to expect helps you prepare and reduces anxiety.

  • Dissociation: feeling of detachment or "floating" (expected therapeutic effect)
  • Nausea: mild, usually manageable with anti-nausea medication if needed
  • Dizziness or lightheadedness: resolves within 1-2 hours
  • Temporary increase in blood pressure and heart rate
  • Visual changes: colors may appear brighter or shifted
  • Drowsiness: plan to rest for several hours after sessions
  • Headache: occasional, typically mild

Who Should NOT Take Ketamine

Certain conditions make ketamine therapy inadvisable. Our physician screening process ensures these are identified before treatment begins.

  • Uncontrolled hypertension (blood pressure consistently above 160/100)
  • Unstable cardiovascular disease or recent heart attack/stroke
  • Active psychosis or schizophrenia
  • Severe liver disease
  • Pregnancy or planned pregnancy
  • Active substance use disorder (particularly with ketamine or PCP)
  • Untreated hyperthyroidism
  • Known allergy to ketamine

Our Safety Protocols

We've built multiple layers of safety into every aspect of treatment. From physician screening to AI monitoring, your wellbeing is protected at every step.

  • Board-certified physician evaluation before any prescription
  • Comprehensive medication interaction review
  • Required trusted companion present during every session
  • AI-powered session monitoring with distress detection (KetAI)
  • One-tap emergency support button in the app
  • Grounding exercises available instantly if distress arises
  • Direct medical team contact for clinical questions
  • Regular follow-up visits to monitor progress and safety

Critical Safety Rules During Sessions

Following these rules during your session is essential for your safety. Your trusted companion should also be familiar with these guidelines.

  • NEVER get in water during or after sessions (bathtub, pool, hot tub—drowning risk)
  • Do NOT drive for at least 5 hours after your session
  • Stay lying down during peak effects (fall prevention)
  • Have your trusted companion present and available throughout
  • Do not operate machinery or make important decisions for several hours
  • Keep your phone accessible for the "I Need Help" button
  • Call 911 for: difficulty breathing, chest pain, seizures, or loss of consciousness

Safety Research & Guidelines

Systematic review of side effects found most adverse effects of ketamine at subanesthetic doses are mild, transient, and self-limiting, including headache, dizziness, and brief dissociation. (Short et al., 2018 (Lancet Psychiatry))

Review of ketamine safety for depression treatment found no significant cognitive impairment, organ damage, or dependence at therapeutic doses with proper monitoring. (Andrade, 2017 (Journal of Clinical Psychiatry))

FDA approval of esketamine (Spravato) established regulatory framework for ketamine-based depression treatment, confirming acceptable risk-benefit profile with proper safeguards. (FDA, 2019 (Spravato Approval))

Frequently Asked Questions

What are the long-term risks of ketamine therapy?

At the low, intermittent doses used for therapy (much lower than recreational use), long-term risks are minimal. Chronic recreational abuse at high doses has been associated with bladder issues, but this has not been observed at prescribed therapeutic doses. Your physician monitors for any concerns at every follow-up visit.

Can I become addicted to ketamine?

Physical dependence on ketamine is rare when used as prescribed under medical supervision. Our protocols use intermittent, controlled dosing with physician oversight—very different from patterns of recreational misuse. If you have a history of substance use disorder, discuss this with your physician during your consultation.

What happens if I have a bad reaction during a session?

Our AI companion (KetAI) monitors for signs of distress throughout your session. If you feel uncomfortable, tap the "I Need Help" button for immediate grounding exercises. Your trusted companion is present to assist. For true medical emergencies (difficulty breathing, chest pain, seizures), call 911 immediately.

Will ketamine affect my ability to think clearly?

During a session, you will experience temporary cognitive changes (this is part of the therapeutic process). These effects fully resolve within 2-4 hours. Studies have found no lasting cognitive impairment from therapeutic ketamine use. Most patients report improved mental clarity as depression and anxiety lift.

Is at-home ketamine as safe as in-clinic treatment?

At-home sublingual ketamine uses lower doses than IV clinic infusions, with a more gradual onset. Combined with our safety protocols (companion requirement, AI monitoring, physician oversight), at-home treatment has an excellent safety record. The at-home setting also eliminates driving immediately after treatment.
