High Risk: Life-threatening combined GABAergic respiratory 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.
GHB acts primarily as a GABA-B agonist and can also affect GABA-A receptors at higher concentrations. Benzodiazepines are positive allosteric modulators at the GABA-A receptor. Together they activate both GABAergic receptor systems at the same time and can produce profound central nervous system depression. The risk of deep unconsciousness, respiratory depression and aspiration is substantially increased.
Mechanism data is language-neutral pharmacological notation. It does not provide amounts, timing or instructions for combining substances.
Pair-specific warning signs have not yet been curated. Breathing problems, loss of consciousness, seizures, chest pain, high fever, collapse or severe confusion remain medical red flags.
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.

Important red flags include breathing problems, loss of consciousness, seizures, chest pain, high fever, collapse or severe confusion. Acute symptoms require medical help and this page does not replace emergency care.
