What is the difference between short- and long-acting ADHD medications?

Donna Hill Howes, RN
Family Medicine
Attention deficit hyperactivity disorder (ADHD) medications vary in the amount of time that they stay active in the body. Some medications are short acting, working to reduce symptoms for about four hours. Long-acting, also called intermediate-acting, drugs work for about eight hours. Others are extended-release formulas, lasting up to 12 hours.

Depending on your child's age, responsibility level, and schedule, your doctor may choose to prescribe a short-acting, long-acting, or extended-release formula. One advantage of the longer-acting formulas is that young children can take one pill in the morning that will last all day. They will not need to remember to visit the school nurse or take a pill during the school day.

Older teens and adults may choose to take short-acting formulas only when they are most in need of the medication, such as before classes or before a big presentation at work.
