Anaphylaxis will most often wake you up.
When you experience anaphylaxis it can cause rapid and life threatening symptoms which include difficulty breathing, low blood pressure, swelling of your face, lips, tongue or throat, hives, nausea and vomiting and even confusion or loss of consciousness.
Anaphylaxis is a life threatening allergic reaction that requires prompt medical attention and even an EpiPen injection immediately.
Biphasic anaphylaxis is the recurrence of anaphylactic symptoms after an initial anaphylactic reaction has seemed to resolved even without further exposure to the allergen and is a two phase reaction, with the second phase appearing after a period of improvement.
Biphasic reaction is when symptoms of anaphylaxis subside and then come back again hours or even days later and can be more severe than the initial reaction.
Anaphylaxis takes around 5 to 30 minutes to occur once you've been exposed to the allergen.
In some cases anaphylaxis can take as long as a few hours to even days for the symptoms of anaphylaxis to appear.
Although in most cases once you've been exposed to the allergen the anaphylaxis often occurs within a few minutes and so it's important to be aware of the symptoms and seek medical attention right away.
Most cases of anaphylaxis occur within 5 minutes to 30 minutes of exposure to the allergen.
And symptoms of anaphylaxis often reach their peak in severity within 30 minutes to 60 minutes.
And anaphylaxis can also last for several hours, although in most cases, the symptoms of anaphylaxis improve within a few hours with appropriate treatment.
In some cases a biphasic reaction may also occur which is when symptoms of anaphylaxis subside and then come back again hours or even days later and can be more severe than the initial reaction.
The symptoms of anaphylaxis can include swelling of the face, lips or tongue, itching, hives, difficulty breathing, wheezing and throat tightness and sometimes vomiting or diarrhea and abdominal pain, along with dizziness, lightheadedness and a rapid or weak pulse.
If you carry an Epipen also known as an epinephrine autoinjector it should be injected right away when you experience the anaphylaxis allergic reaction.
