Doctors know a lot about when to start medications to treat disease. But sometimes our focus on starting medicines means we can confuse providing more care with providing better care. And better care sometimes means fewer medicines, not more.

For instance, patients with high blood pressure who have lost weight or are exercising more may find that they may no longer need blood pressure pills. Patients with heartburn who take proton-pump inhibitors may do just as well with a lower dose or occasional therapy. Patients who take medications for osteoporosis may be candidates for “drug holidays.”

And as we age, our bodies process medications differently and we become susceptible to different side effects. What may have been the right treatment for a patient when she was 50 can turn out to be dangerous at 80.

That may mean many patients can have their treatment deintensified – changing or stopping medicines when they are no longer needed. But it turns out, doctors often don’t do this, even though it means patients risk fewer side effects and can avoid extra health costs. So why, and when, should a person’s drugs be deintensified?
