It's a 16 to 20 week course of treatment and reduces risk of anaphylaxis for accidental exposure to food allergens. There is at least one other drug that is used to treat peanut allergies, but this treats multiple food allergies.
Given that anaphylaxis can be deadly and staff at food places can be sometimes less than reliable about food allergy concerns, I can see this being appealing to someone with severe food allergies who wants a more normal life.
It would be nice if we figured out what causes allergies and fixed it but, I mean, we may never fully solve that. For some people, "take injections for a few weeks and be able to go out with friends without stressing this will involve another life-threatening health event and trip to the ER" will be of adequate value to endure the course of treatment.
