Do not use lisdexamfetamine if you have used an MAO inhibitor such as isocarboxazid (Marplan), tranylcypromine (Parnate), phenelzine (Nardil), rasagiline (Azilect), or selegiline (Eldepryl, Emsam) within the past 14 days. Serious, life-threatening side effects can occur if you take lisdexamfetamine before the MAO inhibitor has cleared from your body.
Do not use this medication if you are allergic to lisdexamfetamine, or if you have hardened arteries (arteriosclerosis), heart disease, moderate to severe high blood pressure (hypertension), overactive thyroid, glaucoma, severe anxiety or agitation, or a history of drug or alcohol addiction.
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.
