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).

How should you treat anaphylaxis?

Treatment

  1. Epinephrine (adrenaline) to reduce your body’s allergic response.
  2. Oxygen, to help you breathe.
  3. Intravenous (IV) antihistamines and cortisone to reduce inflammation of your air passages and improve breathing.
  4. A beta-agonist (such as albuterol) to relieve breathing symptoms.

What type of medication is the most common cause of anaphylaxis?

Antibiotics are the most common culprit of anaphylaxis, but more recently, chemotherapy drugs and monoclonal antibodies have also been shown to induce anaphylaxis. The most severe form of delayed drug reactions not only cause rashes but may also involve other organs including the liver, kidneys, lungs, and heart.

What can anaphylaxis be confused with?

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 …

How quickly does anaphylaxis happen?

Anaphylaxis can occur within minutes – the average is around 20 minutes after exposure to the allergen. Symptoms may be mild at first, but tend to get worse rapidly.

Can anaphylaxis be caused by stress?
