There is good news for people with allergies. The USA has a nasal spray to treat emergency allergic reactions. Up to 40 per cent of people have an allergy. Eleven per cent of people have a food allergy. These can be life-threatening. Allergens like peanuts, dairy products and bee stings can lead to anaphylaxis. People can suddenly experience low blood pressure. Some people get a swollen tongue, which makes breathing difficult. It can lead to death.

The nasal spray means people no longer need an injection. They spray the drug up their nose. A spokesperson said: "Anaphylaxis is life-threatening and some people…may delay or avoid treatment due to a fear of injections." She said the spray was an important drug for people who are afraid of needles. The spray will soon be available in the USA. It is likely to be sold in other countries in the near future.
