Hi, My name is Sandy and I am new to the group. My Mom has MAC and has been on the big 3 for 2 months. She has lost her ability to see color in one eye, so they discontinued the ethambutol. Now, they want to add amikacin but we are not sure about this. I've been reading that some people lose their voice,while on this medicine .Also, vertigo is a possible side effect. My mom has a history with vertigo already. I was just wondering if anyone out there who has taken (inhaled) amikacin (Arikace) could give us the benefit of their experience. Was it worth it from your perspective?
