Doc recommended Arikayce to replace Ethambutol since the latter caused vision issues. I was not approved for Arikayce by Medicare since I do not meet the baseline criteria of positive sputum after 6 months on drug regimen. Plan to appeal, but concerned about likelihood will be approved based on the Ethambutol toxicity issue. Wondering if anyone can share success (of failure) stories regarding Arikayce in similar circumstances. Thanks.
