What does allergy cream do

Some people with severe allergies may experience life-threatening reactions, known as anaphylaxis or anaphylactic shock.

If you’re at risk of this, you’ll be given special injectors containing a medicine called adrenaline to use in an emergency.

If you develop symptoms of anaphylaxis, such as difficulty breathing, you should inject yourself in the outer thigh before seeking emergency medical assist.

Avoiding exposure to allergens

The best way to hold your symptoms under control is often to avoid the things you’re allergic to, although this is not always practical.

For example, you may be capable to help manage:

  1. food allergies by being careful about what you eat
  2. mould allergies by keeping your home dry and well-ventilated, and dealing with any damp and condensation
  3. animal allergies by keeping pets exterior as much as possible and washing them regularly
  4. hay fever by staying indoors and avoiding grassy areas when the pollen count is high
  5. dust mite allergies by using allergy-proof duvets and pillows, and fitting wooden floors rather than carpets

Immunotherapy (desensitisation) 

Immunotherapy may be an option for a little number of people with certain severe and persistent allergies who are unable to control their symptoms using the measures above.

The treatment involves being given occasional little doses of the allergen, either as an injection, or as drops or tablets under the tongue, over the course of several years.

The injection can only be performed in a specialist clinic under the supervision of a doctor, as there’s a little risk of a severe reaction.
