An<unk>  is a sudden and dramatic increase in serum levels of the catecholamines adrenaline and noradrenaline (also known as epinephrine and norepinephrine respectively), with a less significant increase in dopamine transmission. It is a life-threatening condition because of extreme tachycardia and hypertension, and is especially dire for those with prior heart problems. If treatment is prompt, prognosis is good; typically large amounts of diazepam or other benzodiazepines are administered alongside beta blockers. Beta blockers are contraindicated in some patients, so other anti-hypertensive medication such as clonidine may be used. Antipsychotics are also used to treat the most severe psychiatric reactions such as psychosis, paranoia or terror, after their use was formerly discouraged because of their potential to prolong the QT interval; however, more recent research performed since 2019 has revealed that this and other severe side effects are rare and their occurrence does not warrant banning antipsychotics from the treatment of<unk>  crises for which they can be extremely useful.<unk> s are usually caused by overdoses of stimulants, especially cocaine or methamphetamine, or eating foods high in tyramine while taking monoamine oxidase inhibitors. A subarachnoid hemorrhage can also cause an<unk> . A catecholamine storm is part of the normal course of rabies infection, and is responsible for the severe feelings of agitation, terror, and dysautonomia present in the pre-coma stage of the disease.
