thank you for your response and sharing concerns. I am starting rifabutin 300 mg after a week of taking azithromycin and then after another week ethambutol 400 mg. I tried the three antibiotics together in November and got very high fever- my doctor thought it could be the reaction to the meds. The treatment was stopped and I am starting it again but this time she decided it would be one of the three at a time so that we could watch for any adverse reaction. As far as the hearing test, she did not mention hearing test- i was only advised to watch for ringing in my ears and if i notice it I should let them know right away. Well, is it the right course of the treatment? I do not know, I can only hope because it seems to be a rocky road for me- I already changed a pulmonologist. How did you deal with diarrhea? I take a probiotic and eat yogurt and hope it prevents the worst. Are you still taking meds or are you already well? I am still learning how to deal with the thought of being ill and I am only at the beginning of this road. So thank you for your response- i am going to ask for the hearing test and ask about the risk of antibiotic resistance.
