51 years old female has perennial allergic rhinitis and takes 5 mg Cetirizine PO once daily (Due to NAFLD..as shown in the screenshot), and her symptoms are well controlled with this dosage regimen. But, when she takes a bath, this triggers episodes of shortness of breath. So my question how she can manage theses shortness of breath episodes knowing that she won't be able to exceed 5 mg daily of Cetirizine as mentioned by drug monograph (Hepatic impairment takes 5 mg only per day), and also she didn't tolerate intranasal glucocorticoid like fluticasone because she suffered shortness of breath as a side effect of Fluticasone.
Medical History:
