  anti inflammatories usally work by reducing a type of fat known as prostaglandins. They are produced as part of the immune response. There are proteins that are involved in the formation of this fat. I don’t know about allergic responses, thought I suspect it is possible. I know I have asthma and I am told not take some anti inflammatories
