Amphetamine is a central nervous system stimulant that affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control. It is used to treat attention deficit hyperactivity disorder. ADHD
Amphetamine may be habit-forming, and the medicine is a drug of abuse.
Stimulants have caused stroke, heart attack, and sudden death in people with high blood pressure, heart disease, or a heart defect. Do not use amphetamine if you have used an MAO inhibitor in the past two weeks, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.
Amphetamine may cause new or worsening psychosis- unusual thoughts or behavior, especially if you have a history of depression, mental illness, or bipolar disorder. You may have blood circulation problems that can cause numbness, pain, or discoloration in your fingers or toes after using the drug.
Call your doctor if you have: signs of heart problems, feeling light-headed or short of breath; signs of psychosis–paranoia, aggression, new behavior problems, seeing or hearing things that are not real; signs of circulation problems–unexplained wounds on your fingers or toes.
Do not use amphetamine if you are allergic to any stimulant medicine, or if you have: moderate to severe high blood pressure; overactive thyroid;
severe anxiety, tension, or agitation.
