Anaphylaxis is not mild, it is a potentially life-threatening condition. If somebody is getting an anaphylactic reaction from an injection they must stop getting the injections. It is possible to get a mild allergic reaction from the drug, in which case one has to consider the pros and cons of getting it. It is also possible to get an irritation of the area if the injection is constantly being given in the same site (which it shouldn't be). This irritation is from the needle rather than the drug. Rotation of injection site should stop this problem.
