There is good news for people who have allergies.  Food and Drug Administration (FDA) in  USA has approved  nasal spray to treat emergency allergic reactions. The WHO says up to 40 per cent of people worldwide suffer from  allergy. Around 11 per cent of people have  food allergy. Allergies can cause  condition called anaphylaxis. This is life-threatening. Anaphylaxis is caused by allergens like peanuts, dairy products, bee stings, fresh fruit and many other things. People who suffer anaphylactic shock can have different symptoms. These include dangerously low blood pressure, vomiting or diarrhoea. Some people experience  swollen tongue and / or throat, which can cause trouble breathing and lead to death.
 new nasal spray is called Neffy. It means people no longer need  EpiPen injection. They simply spray the drug up their nose. This is welcome news for people who have  fear of needles. Neffy is  first treatment of anaphylaxis that is not treated by  injection. An FDA spokesperson said: "Anaphylaxis is life-threatening and some people, particularly children, may delay or avoid treatment due to  fear of injections. The availability of  nasal spray may reduce barriers to rapid treatment of anaphylaxis." She added: "Neffy provides  important treatment option, and addresses  unmet need." Neffy will initially be available in  USA. It is likely to be rolled out worldwide in  coming years.
