While the cause of idiopathic anaphylaxis remains unknown, prompt treatment with intramuscular epinephrine (adrenaline) administered into the anterolateral aspect of the thigh is associated with good prognosis. There may also be a role for H1-antihistamines and corticosteroids as second-line agents.

Does idiopathic anaphylaxis go away?

What is a idiopathic anaphylactic reaction?

INTRODUCTION Anaphylaxis is often associated with an identifiable trigger, such as a food, medication, or insect sting.

from recurrent episodes of idiopathic anaphylaxis — a potentially life-threatening condition of unknown cause characterized by a drop in blood pressure, fainting episodes, difficulty in breathing, and wheezing.

Can stress cause idiopathic anaphylaxis?

Can anaphylaxis cause long term damage?

When major organs don’t get the blood and oxygen they need to function, your body goes into anaphylactic shock. This is a life-threatening medical emergency. When left untreated, anaphylactic shock can lead to internal organ damage, or even cardiac arrest.

What is the evidence for the treatment of idiopathic anaphylaxis?

Idiopathic anaphylaxis is a rare life-threatening disorder with symptoms similar to other forms of anaphylaxis. There is lack of a robust evidence base underpinning the treatment of anaphylaxis and even less so for idiopathic anaphylaxis. Much of the evidence therefore comes from relatively small case series and expert opinion.

Which medications are used in the treatment of anaphylaxis?

Patients with frequent episodes of anaphylaxis (e.g., six or more episodes/year) should be considered for preventive therapy, which may include corticosteroids, H1- and H2-antihistamines, and, in some cases, mast cell stabilizers such as ketotifen.

What should be monitored in the care of anaphylactic shock patients?
