Alprazolam Interactions

Alcohol and alprazolam (Xanax) both depress the central nervous system by enhancing GABA-A receptor activity. Taken together they produce additive — and sometimes synergistic — sedation, slowed breathing, and impaired coordination, which substantially raises the risk of overdose and death even when neither is taken in a large amount.

Kava's active compounds (kavalactones) act on the brain's GABA-A receptor, the same inhibitory system that alprazolam, a benzodiazepine, enhances. Taken together they cause additive central nervous system depression. A published case report describes a previously healthy 54-year-old man who became semi-comatose after three days of combining kava with his prescribed alprazolam, recovering once the kava was stopped. Kava also carries an independently documented risk of liver injury.

Alprazolam and melatonin both promote sleep and can produce additive sedation, so taking them together may increase drowsiness, slow reaction time, and carry over into next-day grogginess. The combination is generally manageable but warrants your prescriber's awareness, especially for older adults and anyone who drives in the morning.
