Ketamine therapy UK status

Ketamine therapy uses low, carefully controlled doses of ketamine, typically alongside psychological support, to treat severe treatment-resistant depression and some other mental health conditions. It works differently from standard antidepressants, acting rapidly on brain glutamate pathways.

Yes, ketamine-based treatment (including esketamine nasal spray, which is licensed) is available in the UK for treatment-resistant depression, but it is tightly regulated and only administered in specialist clinical settings under medical supervision. It is not something that can be self-administered or obtained outside a monitored clinical programme.

Possible side effects include dissociation, nausea, raised blood pressure, dizziness and, with repeated unsupervised use, bladder damage. These risks are why treatment is delivered under close medical monitoring with careful dose control.

When properly supervised in a clinical setting with appropriate patient selection and monitoring, it is generally considered safe, but risks increase significantly with unsupervised or recreational use. Clinics carefully screen for contraindications such as certain heart or psychiatric conditions before starting treatment.

It is typically considered for people with severe depression that hasn't responded to standard antidepressants and psychological therapy, sometimes alongside certain anxiety or PTSD presentations. A thorough psychiatric assessment is needed to confirm suitability and rule out contraindications.

Many patients experience a rapid improvement in mood within hours to days of treatment, which can be dramatic for those who haven't responded to other treatments, though effects may need to be maintained with repeated sessions. It is generally used alongside, not instead of, ongoing psychiatric care.

It's given either as an intravenous infusion, intramuscular injection, or as a licensed nasal spray (esketamine), always within a monitored clinical setting with medical staff present for the duration of the session. Sessions are typically followed by observation before the patient goes home.

Initial improvements can be short-lived after a single session, which is why treatment is usually given as a course with maintenance sessions to sustain benefit. Your psychiatrist will tailor the frequency based on your response.

Standard antidepressants typically take weeks to work and act on serotonin or noradrenaline pathways, while ketamine acts much faster via different brain pathways and is generally reserved for treatment-resistant cases under specialist supervision. Ketamine therapy is not usually a first-line treatment.

If standard depression treatments haven't worked after reasonable trials, ask your GP or psychiatrist about specialist assessment for options including ketamine therapy. Private psychiatric consultations can typically be arranged within about two weeks, considerably faster than typical NHS specialist mental health waiting times.
