  • Strongly recommended

    Quitting smoking will do more for your heart than any medication on this page. Ask specifically about varenicline, or a nicotine patch combined with a lozenge.

    Proven in trialsTrials counted real events, like heart attacks, strokes, or deaths, and this changed them.

    Why, and the source

    Willpower alone succeeds perhaps 5% of the time; medication plus counselling multiplies that severalfold. Varenicline is the most effective single drug; combination nicotine replacement (a patch for the baseline plus a lozenge or gum for cravings) is close behind and available without a prescription. Free coaching is available at 1-800-QUIT-NOW. Excess risk of a heart attack starts falling within weeks and drops substantially over the first year.

    Where the guidelines stand

    ACC/AHA (US)

    • RecommendsClass 1Level A

      Being asked about tobacco at every visit, being firmly advised to quit, and behavioural support combined with medication are each Class 1, Level A, in the 2019 primary prevention guideline, the 2023 chronic coronary disease guideline and the 2024 peripheral artery disease guideline. Picking varenicline over the other medications is a weaker, Class 2b, recommendation.
