In most cases, medicines can help control symptoms of ADHD. Most often, you'll use medicine along with therapy, coaching, and lifestyle changes. Your doctor may prescribe a stimulant to help you stay focused. Or you may take a type of antidepressant or other medicine. It may take some time to find what works best for you. Keep in mind that medicines don't cure ADHD. And they may cause side effects, such as headaches, trouble sleeping, or stomach problems. Take your medicine as prescribed. If you're bothered by side effects, be sure to tell your doctor. Never share your medicine or use another person's. Store your medicine in a secure location. Always talk with your doctor before making any changes to your medicine.
