Medication side effects that can mimic "getting older"

Some prescription and over-the-counter drugs produce side effects that resemble problems tied to aging, such as memory lapses, balance issues, or fatigue. Older adults are more sensitive to medication side effects because their body composition and metabolism change.

Ways to maximize your energy

People’s energy levels typically decrease later in life as a result of aging, illness, or other factors. Fortunately, a healthier lifestyle can boost energy. That involves eating a diet low in added sugars and processed foods, getting seven to nine hours of sleep each night, managing stress, getting lots of aerobic exercise, and strengthening the muscles. Using physical energy frugally is another useful strategy. For example, it helps to perform activities at a slow, steady pace instead of a fast pace; to break activities into small tasks instead of one large job; and to rest between tasks.

Is your medication killing your sex drive?

Low libido can include both less desire for and less satisfaction with sex. A variety of medications can dampen sex drive by altering hormone levels or nerve signals, dulling sensation in the genitals, or triggering fatigue or mood changes. They include some antidepressants, cardiovascular drugs, antihistamines, antiseizure drugs, opioids, chemotherapy, hormone blockers, oral contraceptives, and fertility drugs. People whose medications affect their libido can ask their doctor to adjust the dose or timing or substitute another drug without sexual side effects.

Is your home blood pressure monitor accurate?

Many home blood pressure monitors are not validated for accuracy, which means there's no way to know if information they provide is correct. Relying on inaccurate measurements can affect decisions people make about medical treatment. Fortunately, reliable organizations have developed lists of blood pressure monitors that have demonstrated clinical accuracy. If a blood pressure monitor isn't listed, it's probably not validated.

GLP-1 drugs may lower odds of developing substance use disorders

A 2026 study suggests that people who take GLP-1 drugs—prescribed for diabetes and weight loss—are less likely to develop a substance use disorder. Among people who already have addiction, use of a GLP-1 was linked with fewer complications such as overdose and death.
