There is good news for people with allergies. The USA has approved a nasal spray to treat emergency allergic reactions. Up to 40 per cent of people suffer from an allergy. Around 11 per cent of people have a food allergy. Allergies can cause a life-threatening condition called anaphylaxis. This is caused by allergens like peanuts, dairy products, bee stings, and other things. People who suffer anaphylactic shock can have different symptoms. These include low blood pressure and vomiting. Some people get a swollen tongue or throat. This can make breathing difficult and lead to death.

The nasal spray is called Neffy. It means people no longer need an injection. They spray the drug up their nose. Neffy is the first treatment of anaphylaxis that is not treated by an injection. A spokesperson said: "Anaphylaxis is life-threatening and some people, particularly children, may delay or avoid treatment due to a fear of injections." She added: "Neffy provides an important treatment option, and addresses an unmet need." Neffy will soon be available in the USA. It is likely to be sold in countries worldwide in the coming years.
