Sometimes, staying focused on one thing can be difficult for you, especially for your child. Even the smallest things can distract you, make it hard to stay in one place, and make you do whatever comes to mind without control. In medical terms, we call this condition ADHD (Attention-Deficit Hyperactivity Disorder) . Today, we are talking about a drug that doctors often recommend to control this condition, but which many people are not exactly aware of. It is a combination of two drugs called amphetamine and dextroamphetamine.
What is this medicine and how does it work?
Simply put, this is a medication that is used to treat ADHD. It belongs to a class of drugs called stimulants. The word "stimulant" may scare some people, but it works by slightly increasing the activity of the parts of the brain that control attention and behavior. Much like the jolt that comes from drinking coffee after a nap, this medication helps the brain stay focused and reduce impulsive behavior .
This medication may come under different brand names in Sri Lanka and abroad, such as Adderall XR and Mydayis. Also, sometimes your doctor may prescribe this medication for other medical conditions.
