According to the International Programme on Chemical Safety (IPCS) and the United States Food and Drug Administration (USFDA),<unk>  is contraindicated in people with a history of drug abuse, cardiovascular disease, severe agitation, or severe anxiety. It is also contraindicated in individuals with advanced arteriosclerosis (hardening of the arteries), glaucoma (increased eye pressure), hyperthyroidism (excessive production of thyroid hormone), or moderate to severe hypertension. These agencies indicate that people who have experienced allergic reactions to other stimulants or who are taking monoamine oxidase inhibitors (MAOIs) should not take<unk> , although safe concurrent use of<unk>  and monoamine oxidase inhibitors has been documented. These agencies also state that anyone with anorexia nervosa, bipolar disorder, depression, hypertension, liver or kidney problems, mania, psychosis, Raynaud's phenomenon, seizures, thyroid problems, tics, or Tourette syndrome should monitor their symptoms while taking<unk> . Evidence from human studies indicates that therapeutic<unk>  use does not cause developmental abnormalities in the fetus or newborns (i.e., it is not a human teratogen), but<unk>  abuse does pose risks to the fetus.<unk>  has also been shown to pass into breast milk, so the IPCS and the USFDA advise mothers to avoid breastfeeding when using it. Due to the potential for reversible growth impairments, the USFDA advises monitoring the height and weight of children and adolescents prescribed an<unk>  pharmaceutical.
