Alcohol and Zolpidem, contraindicated.
Alcohol adds to zolpidem's hypnotic and psychomotor-impairing effects. Controlled testing showed both zolpidem and alcohol impaired cognitive and motor performance, and real-world reports link zolpidem to confusion, amnesia, sleep-driving, and complex behaviors. Alcohol increases the danger of these behaviors and next-day impairment.

Contraindicated
What is happening. Alcohol adds to zolpidem's hypnotic and psychomotor-impairing effects. Controlled testing showed both zolpidem and alcohol impaired cognitive and motor performance, and real-world reports link zolpidem to confusion, amnesia, sleep-driving, and complex behaviors. Alcohol increases the danger of these behaviors and next-day impairment.
Mechanism. Zolpidem is a GABA-A receptor positive modulator with relative alpha-1 selectivity. Alcohol adds broad CNS depression through GABA-A potentiation and NMDA inhibition, worsening vigilance, memory, balance, and reaction time.
Recommendation. Do not drink alcohol on nights you take zolpidem. Do not take zolpidem after drinking, even if you feel awake. Seek help if sleepwalking, sleep-driving, severe confusion, or unusual behavior occurs.
