Inhaled Tobi vs. Tobramycin


Hi everyone!
My insurance recently made me switch from Tobi brand Tobramycin to generic Tobramycin (both inhaled).
During the last few Tobramycin months (cycled with Cayston) I have started to feel achy and have a drier, more persistent cough than I remember while being on Tobi brand. I am also doing the Tobramycin in the eRapid. I should keep a symptom journal, but realistically I don't. Has anyone else felt like this if they had to make a switch?
