Although the adrenaline
helped with the severe symptoms, she is either having swelling of the throat or has other allergies with concomitant asthma.
She needs complement C3 C4 levels checked to ensure there is no C1-inhibitor
deficiency (although quite rare but important to exclude), skin tests to ensure she does not have other allergies that are causing these attacks. Hidden allergens in foods such as seeds (sesame) can be checked at the same time.
A trial of bronchodilators (with steroids
) and/or montelukast
for 3 months may also be necessary.
Continuous use of antihistamines would also help with throat swelling if she has allergen-induced or idiopathic angioedema
