MAJOR — Use With Caution
🔴 MAJOR — Do NOT drink alcohol with Diazepam.
Evidence level: STRONG
Alcohol and diazepam together dangerously suppress breathing. Diazepam stays in your body for days, so effects last much longer than the drink.
Additive CNS and respiratory depression. Diazepam's long half-life (20-100h) means effects persist even after alcohol wears off.
Avoid alcohol while taking diazepam. Due to diazepam's very long half-life, wait at least several days after your last dose before drinking.
Take Diazepam only as prescribed — benzodiazepines carry dependence risk and should not be adjusted without medical guidance. Alcohol at a separate time. Food slows benzodiazepine absorption (delayed but longer effect). NEVER combine with alcohol. Avoid grapefruit — it increases blood levels of many benzodiazepines.
Elderly, liver disease, other sedatives
Extreme drowsiness, slowed breathing, confusion, loss of consciousness

Combining sedatives increases overdose risk. Discuss with your doctor: magnesium glycinate, L-theanine, or passionflower may provide anxiety relief with fewer interaction risks. Never stop benzodiazepines abruptly — taper under medical supervision.
