Exercise and Medication: What You Need to Know
Physical activity is vital for health, but it can interact with your medications in unexpected ways. Stay informed to exercise safely.
Exercise Affects How Medications Work
Physical activity changes blood flow, body temperature, and metabolic rate, all of which can affect drug absorption and distribution. While exercise is beneficial for nearly everyone, being aware of how it interacts with your medications helps you stay safe and get the most from both your workout and your treatment.
Blood Pressure Medications and Exercise
Blood pressure medications lower your resting blood pressure, which is their intended effect. During exercise, however, this can sometimes cause blood pressure to drop too low, leading to dizziness or lightheadedness. Start new exercise routines gradually and stay hydrated. If you feel dizzy during a workout, stop and rest.
Diabetes Medications and Blood Sugar
Exercise lowers blood sugar, and so do many diabetes medications. This combination can sometimes cause hypoglycemia (dangerously low blood sugar), especially with insulin or sulfonylureas. Check your blood sugar before, during, and after exercise. Keep fast-acting glucose tablets or juice nearby in case of a low episode.
Beta-Blockers and Heart Rate
Beta-blockers limit how fast your heart can beat, which means your heart rate may not rise as expected during exercise. Do not rely on heart rate to gauge exercise intensity if you take beta-blockers. Instead, use the "talk test" or a perceived exertion scale to monitor how hard you are working.
Timing Exercise Around Medications
- Avoid intense exercise immediately after taking a new medication if you are unsure of its effects
- If a medication causes drowsiness, schedule exercise before taking it rather than after
- For insulin users, avoid injecting into a muscle area that will be heavily used during exercise, as this can speed absorption unpredictably
General Exercise Guidelines
The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic activity per week. This can include brisk walking, cycling, or swimming. Strength training two days per week is also recommended. Always discuss new exercise plans with your doctor, especially if you take medications for chronic conditions.
