As I Look Into The Helpful Benefits Of Singulair, It

As I look into the helpful benefits of Singulair, it appears to be more for respiratory conditions. My daughter's allergist has prescribe this for her but she has more topical (skin) reactions and sensitivities. She is allergic to many animals with fur; she reacts with sneezes and can get rashes and did get hives once. He also, has her taking Zyrtec and using Fluticasone Propionate as needed. I just wonder if we really need to be taking the Singulair. I just feel like this is a lot of medicine.
