Treatment for food allergies usually involves avoiding the allergen and, if needed, prescribing allergy medication to treat any instances of exposure. For mild reactions, antihistamines may be prescribed to relieve symptoms like itching and hives. However, they are not effective for severe reactions.
For severe allergic reactions (anaphylaxis) to food, an adrenaline auto-injector should be used immediately. This can rapidly reverse the symptoms and is a life-saving measure. After using the adrenaline auto-injector, or if one is not available, call for an ambulance immediately. Severe allergic reactions can be life-threatening and require urgent medical attention.
