The USA has a spray for emergency allergic reactions. Around 40 per cent of people have an allergy. Eleven per cent of people have a food allergy. These can kill people. Things like peanuts, milk and bee stings can cause low blood pressure. Some people get a swollen tongue. This makes breathing difficult. People can die.

The spray can be used instead of an injection. People spray the drug up their nose. This will help people who are afraid of injections and needles. The spray will help people who get a serious allergic reaction called anaphylaxis. The spray will be available in the USA. It is likely to be sold in other countries in the next few years.
