Complications
Complications
- Anaphylaxis (life-threatening allergic reaction).
- Breathing problems and discomfort during the allergic reaction.
- Drowsiness and other side effects of medicines.
Prognosis
Prognosis
Most allergies can be easily treated with medication. Some children may outgrow an allergy. This is particularly true of food allergies. However, as a general rule, once a substance has triggered an allergic reaction, it continues to affect the person.
Allergy shots are most effective when used to treat those with hay fever symptoms and severe insect sting allergies. They are not used to treat food allergies because of the danger of a severe reaction. Allergy shots may require years of treatment, but they work in most cases. However, they may cause uncomfortable side effects (such as hives and rash) and dangerous outcomes (such as anaphylaxis).
