欧博百家乐Hives that come and go daily: Causes and trea
Anaphylaxis is a severe allergic reaction that can be life threatening. The symptoms develop suddenly and include:
hives
swelling of the face or mouth
wheezing
fast, shallow breathing
a fast heart rate
clammy skin
anxiety or confusion
dizziness
vomiting
blue or white lips
fainting or loss of consciousness
If someone has these symptoms:
Check whether they are carrying an epinephrine pen. If they are, follow the instructions on the side of the pen to use it.
Dial 911 or the number of the nearest emergency department.
Assist the person in moving from a sitting position to lying down. If they have vomited, turn them onto their side.
Stay with them until the emergency services arrive.
Some people may need more than one epinephrine injection. If the symptoms do not improve in 5 to 15 minutes, or they come back, use a second pen if the person has one.
