Summary
Oxybates are potent CNS depressants and combining them with benzodiazepines increases the risk of profound sedation, respiratory depression, coma and death. Oxybate labeling advises against concurrent use with sedative hypnotics.
What this interaction means in plain words
Calcium / magnesium / potassium / sodium oxybates and Clonazepam are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Why it happens
Additive CNS and respiratory depression via GABA-B agonism from oxybate and GABA-A potentiation from clonazepam.
What to do
Avoid the combination; replace the benzodiazepine or reconsider the oxybate. If unavoidable, use minimal doses with close monitoring of consciousness and respiration.
