What can mimic anaphylaxis?
The most common conditions that mimic anaphylaxis include: vasodepressor (vasovagal/neurocardiogenic) reactions (which are characterized by hypotension, pallor, bradycardia, weakness, nausea and vomiting); acute respiratory decompensation from severe asthma attacks, foreign body aspiration and pulmonary embolism; vocal …
Can you survive anaphylaxis without treatment?
This is a dangerous and life-threatening situation called anaphylactic shock. Symptoms of anaphylaxis can be mild, and they may go away on their own (most anaphylactic reactions will require treatment). But it’s difficult to predict if or how quickly they will get worse.
