Alcohol use is a contraindication for varenicline because it can increase intoxication, aggression, and amnesia.

• A. True
• B. False
• C. Only with high doses
• D. Only if combined with benzodiazepines

Answer: (A)

Alcohol use while taking varenicline raises safety concerns because the combination can worsen central nervous system effects, leading to greater intoxication, mood changes such as aggression, and memory problems. Varenicline acts on brain pathways that influence impulse control and reward, and alcohol can amplify impairments in judgment and memory, increasing the risk of adverse events. Because of these potential risks, avoiding alcohol during treatment is advised. If drinking cannot be avoided, discuss with a clinician to weigh benefits and risks and monitor closely for adverse effects.
