Ketamine Therapy Safety: How Risks Are Anticipated, Monitored, and Managed

Please note that throughout this blog, we may refer to ketamine, esketamine, and Spravato relatively interchangeably. This is due to the inherent similarities in chemical makeup between ketamine and esketamine, and their similar effects on mental health conditions. In the event that this creates confusion, don't hesitate to reach out to Lumin Health staff to ask any questions about treatment at hello@lumin.health or by scheduling a free consultation.

Ketamine’s Risk Isn’t Zero – It’s Managed: Here’s How

For safety-conscious readers who want specifics, not headlines.

If you’re considering ketamine therapy or esketamine (Spravato), it helps to see how reputable teams like Lumin Health plan for risk. Thorough psychiatric-informed care doesn’t hand-wave; it anticipates, monitors, and responds.

The purpose of vital sign monitoring and post-dose observation in ketamine therapy 

Why Lumin Health check vitals during ketamine therapy 

Ketamine treatment can briefly raise blood pressure and heart rate, and some people feel light-headed, anxious, or drowsy, so taking these baseline vitals help us know your starting point. Repeat checks during sessions tell us how your body is responding to the ketamine in real time. That information guides simple steps like adjusting room stimuli, offering fluids, positioning your body, or – when appropriate – treating a persistent symptom.

Why you stay at Lumin Health after ketamine dosing

Observation time is a mandatory part of the treatment so that we can ensure you’re safe and comfortable. Your perception, coordination, and alertness can fluctuate as ketamine for depression wears off, so staying in a quiet, supervised space allows staff to confirm that your vitals are trending back toward baseline, that nausea is controlled, and that you feel steady before leaving Lumin Health.

What ketamine dosing day looks like to you.

  • A calm room, blood pressure cuff, and pulse checks at planned intervals
  • A team of dedicated mental health experts who ask about sensations, anxiety, or side effects
  • Clear green-light criteria before discharge and a ride home arranged in advance

This is the difference between ketamine therapy as medical care and a do-it-yourself experience.

Concrete examples: aspiration during ketamine therapy and how staff respond

Nausea can occur with ketamine treatment. If someone vomits while drowsy, there is a small risk of aspiration, so Lumin Health’s protocol is designed to intervene as necessary. 

How Lumin Health plans ahead

  • Before dosing: We guide patients to avoid eating prior to treatment, e review medical history, and discuss anti-nausea options if you’re prone to nausea.

  • During dosing: We provide head elevation in our comfortable reclining chairs, a nearby emesis bag, and a team of experts within arm’s reach.

  • If vomiting occurs: We help. We’ll make sure that, if in the unlikely event you feel unwell, you are supported and all measures available to us to help you feel better are provided.

The goal isn’t to pretend nausea won’t happen, because it might be unavoidable in certain cases. The goal is to prevent it when we can and respond quickly if it does.

When we say “no ketamine dosing is possible today”: red-flag scenarios

At Lumin Health, we might occasionally recommend waiting. That’s not a setback – it’s designed to be careful judgment with your safety in mind. 

Common reasons to pause or reschedule:

  • Blood pressure well above safe thresholds at baseline
  • New sedating medications started since your last visit or recent alcohol/other substance use
  • Acute illness (fever, vomiting, dehydration, respiratory infection)
  • No ride home after treatment
  • A significant destabilizing life event that makes today feel unsafe
  • Unresolved questions about pregnancy status or new cardiac symptoms

You’ll always hear the reason for rescheduling a ketamine session, Lumin Health’s plan to address it, and how we look at reconsidering. This is so your agency as the patient stays central.

What is the risk of ketamine therapy if I’m on other medications?

Tell your Lumin Health team every medication you take – including prescriptions, over-the-counter meds, and supplements. Some medicines can stack risk when combined with ketamine therapy, especially sedatives (for example, benzodiazepines, sleep aids, opioids) and agents that affect blood pressure for example. At Lumin Health, we will: 

  • Review your full list and coordinate with your external care team when relevant
  • Give day-of guidance about what to continue, hold, or time differently
  • Adjust dose or scheduling if side effects were tough last time
  • Pause treatment if the combination isn’t safe today

Never stop or change a home medication without consulting a healthcare provider. Decisions are individualized, and collaboration keeps you safe.

Managing ongoing risk in ketamine therapy 

Ketamine therapy isn’t risk-free. It’s risk-managed. Vital sign monitoring, post-dose observation, and a readiness to say “not today” are features of careful Spravato treatment – evidence that your safety matters as much as your outcomes. If you want to see these systems up close, a consult at a Spravato clinic is a low-stakes first step. Ask every question you have. What matters most is what feels possible to you.
