High Risk: Additive central nervous system depression
Synapedia classifies this as a high-risk interaction context. Warning signs should be taken seriously and medically assessed. This page can provide source-linked orientation, but it is not medical advice, a dosing guide or a claim that the combination can be made safe.
Ketamine and alcohol both depress central nervous system activity. Used together they can produce stronger than expected sedation, impaired motor control, disorientation and, at higher levels, reduced consciousness. This raises the risk of falls, accidents, vomiting and airway obstruction while sedated.
Mechanism data is language-neutral pharmacological notation. It does not provide amounts, timing or instructions for combining substances.
If acute symptoms appear, seek emergency medical help. Do not wait when breathing, consciousness, seizures, chest pain or severe confusion are involved.
Both substances bind to the following receptors, increasing the risk of pharmacological interactions.

Ketamin verändert Wahrnehmung, Koordination und Bewusstsein; Alkohol dämpft ZNS, Motorik und Schutzreflexe.
Important red flags include Nicht weckbar, Bewusstlosigkeit oder wiederholtes Wegtreten, Langsame, unregelmäßige oder auffällige Atmung; bläuliche Lippen, Erbrechen bei starker Sedierung, Husten nach Erbrechen oder Aspirationsverdacht. Acute symptoms require medical help and this page does not replace emergency care.
