Take medication exactly as prescribed — don’t stop just because you feel better
药按医嘱吃满，别感觉好了就停
There’s no cost at all; in fact, it saves money on future treatment for complications. Taking the pills each day takes only a few minutes. The real challenge is sticking to the regimen every single day.
People who consistently follow their doctor’s instructions when taking medication have roughly half the risk of dying during the same period compared to those who take it intermittently. This figure should be viewed with some caution. Even individuals who take fake pills consistently also have lower mortality rates, which suggests part of the benefit stems from the fact that people who stick to any medication routine tend to be more health-conscious overall. Still, the risks of skipping doses are well documented — especially for blood pressure drugs, anticoagulants, and anti-rejection medications.

The excuse
The routine already works until the day the source says it may not.
What feels good now
Today I keep a few minutes, a bit of persistence and avoid interrupting my default routine.

1. Take medication exactly as prescribed — don’t stop just because you feel better
Cost: There’s no cost at all; in fact, it saves money on future treatment for complications. Taking the pills each day takes only a few minutes. The real challenge is sticking to the regimen every single day.
In plain terms: People who consistently follow their doctor’s instructions when taking medication have roughly half the risk of dying during the same period compared to those who take it intermittently. This figure should be viewed with some caution. Even individuals who take fake pills consistently also have lower mortality rates, which suggests part of the benefit stems from the fact that people who stick to any medication routine tend to be more health-conscious overall. Still, the risks of skipping doses are well documented — especially for blood pressure drugs, anticoagulants, and anti-rejection medications.
Benefit: This finding comes from a meta-analysis that pooled data from 21 separate studies involving 46,847 participants. Compared to those who took medication irregularly, people who followed their prescription exactly had roughly 44% lower risk of dying during the same timeframe. The raw odds ratio was 0.56, with a 95% confidence interval ranging from 0.50 to 0.63; this interval represents the range within which the true value is likely to fall. When only treatments with proven effectiveness were considered, the risk reduction was about 45% (odds ratio 0.55, 95% CI 0.49–0.62).

Notes: This is a somewhat controversial figure and one of the numbers in this guide that requires extra caution. In the same meta-analysis, individuals who consistently took placebos also showed a lower mortality rate (odds ratio 0.56, 95% CI 0.43–0.74). This indicates that a significant portion of the benefit is attributable to the “healthy adherer effect” — the tendency of people who stick to any kind of medication routine to generally maintain healthier habits. Nevertheless, the risks associated with discontinuing medication are very real, particularly for blood pressure drugs, anticoagulants, and anti-rejection medications.

1. 药按医嘱吃满，别感觉好了就停
成本: 不花钱，反而省下以后治并发症的钱。每天吃药占不了几分钟，难在一天不落地吃下去。
说人话: 按医生说的把药吃满的人，同期死亡的可能性大约只有断断续续吃药的人的一半。这个数要打折看。连假药都吃满的人死亡率也低，说明有一部分好处来自「能坚持吃药的人本来就更注意健康」。但停药的害处是确定的，降压药、抗凝药、抗排异药尤其如此。
收益: 21 项研究、46847 人合起来算（荟萃分析）：和吃药断断续续的人相比，按医嘱吃满的人同期死亡的可能性约低 44%。原值是比值比 0.56，95% CI 0.50–0.63（可信范围）。只看确有疗效的治疗，约低 45%（0.55，0.49–0.62）

备注: 争议。这也是这本书里最需要打折看的一个数字。同一项汇总分析里，连安慰剂（假药）都吃满的人死亡率也低（0.56，0.43–0.74）。这说明相当一部分好处来自「能坚持吃药的人本来就更注意健康」。作者把这层混进来的因素叫健康依从者效应。但停药本身的害处是明确的，尤其是降压药、抗凝药和抗排异药
