Serious, life-threatening side effects can occur if you take lisdexamfetamine before the MAO inhibitor has cleared from your body.

Some stimulants have caused sudden death in children and adolescents with serious heart problems or congenital heart defects. Before taking lisdexamfetamine, tell your doctor if you have any type of heart problems.

Lisdexamfetamine may be habit-forming and should be used only by the person it was prescribed for. Lisdexamfetamine should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it. Using this medication improperly can cause death or serious side effects on the heart.
