Stella was on Hydroxyzine but after a few days she started acting paranoid, couldn't tell it helped the scratching much. She is taking Atopica and the scratching has improved alot, after a month of taking it daily we were able to start every other day which has helped with the expense. Sometimes it does cause an upset tummy which is one of the side effects. We didn't have allergy testing either but she was scratching so badly we couldn't risk clearing her system to do the test at that time. My vet could do the test where they draw blood but for the skin scratch test she would have to go to an allergist. From what I have been told the results of the first test (blood) sometimes isn't very conclusive. Good luck, itchy furbutts are the pits |
