Before using Premarin she used different medications and she had allergic reactions to all of them, including Estrace 0.1%, Mylan, Ativan (two different generics), she ended up having reactions to these medications and every time she used them she got sick. Her skin is really sensitive overall  and reacts to the seizing that they put in clothing  developing eczema, she also had a couple of episodes of skin reactions with poison ivy.

Caller does not believe that she will be using Premarin vaginal cream because of this, during the call she mentioned that she might get an infection for using the applicator and even though it can be washed it´s "disgusting". She used her syringes from her "old doses" to apply the product and the syringe didn´t even have a calibration for 0.5, she didn´t use the applicators from Pfizer that came with the box.
