At the moment, there is no “cure” for food allergies. People with an allergy need to avoid that particular food (or foods). They must read all food labels and understand the scientific words for the foods in case they are not labelled clearly.
At the same time it is essential to provide a balanced diet with enough protein, energy, minerals and vitamins. A qualified dietician may be able to guide you on how to ensure this.
For immediate-type reactions the patient must know how to recognise and treat an allergic reaction, in case they accidentally eat this food. To help them, AFSA has an emergency action plan that details how to recognise a reaction and how to treat it. (See anaphylaxis action plan)
For milder reactions, just an antihistamine is given. However for more severe reactions, a dose of adrenaline given by injection into a muscle can be life-saving. The doctor will advise if the patient are at risk of severe reactions and whether they need an adrenaline pen.
Patients with food allergy must see a doctor with experience in food allergies regularly. The doctor will check whether they are managing to avoid the food, whether accidental reactions are being treated properly, whether the risk of severe reactions has changed and whether there are signs that the allergy may be outgrown. If the doctor thinks there is a chance of the allergy being out grown s/he may repeat skin or blood tests and then do an oral food challenge test.
