Of course it is possible, but it is not as easy as one would wish.

Epinephrine has been a great cure in the case of acquired angioedema, but its results are not so good when dealing with hereditary angioedema treatment. However, you may have an allergy test at your Doctor. You may also get urine and blood tested in order to find out, if you have angioedema or not. If the results are positive, it can be cured with certain therapies or antihistamines. If you experience difficulty in breathing, try to go in the open air and breathe slowly and consult a doctor immediately. The most important thing is avoiding any other drugs when you are affected by angioedema.
