Count a week's drinks, then discuss them briefly with a clinician

Grade A evidenceValue: Moderate
In plain language

A clinician spending a few minutes reviewing your intake, explaining risk and agreeing a goal led to an average reduction of 20 g of pure alcohol weekly after a year—about half a liter of beer. Longer discussions did not add benefit. For people unable to control drinking, two medicines studied abroad helped; roughly one additional person benefited for every 12 treated.

What you may gain

Across 34 randomized trials with 15,197 people, brief intervention reduced weekly alcohol intake by 20 g at one year versus minimal or no intervention (95% CI 12–28 g less; moderate-quality evidence). Average baseline intake was 244 g/week. Brief intervention meant no more than 5 contacts totaling under 60 minutes of advice or lifestyle counseling; longer intervention added no benefit. Across 122 medication trials involving 22,803 people, acamprosate prevented one additional return to any drinking per 12 treated (95% CI 8–26). Oral naltrexone at 50 mg/day prevented one additional return to heavy drinking per 12 treated (8–26).

Context & considerations

The benefit rating is small because the measured outcome is alcohol consumption, a surrogate rather than mortality. Medication trials were mostly outside China, generally involved alcohol-dependent participants, and included psychosocial care; the numbers are additional benefits on top of that support. Chinese indications and prescribing availability depend on clinicians and product labeling; do not buy these medicines online yourself. See withdrawal precautions.
