I have hearing problem, approx 60% lees hearing in Right ear. I took Deza 30 and other medicine for last 35 days. Defza-30 dose was 1st. 5-days 2 dailly, then 1 for next 10 days, then1/2 for 10 days and finally defza-6 for 10-days as suggested by my doctor. When I completed defza-30, 1/2 per day, I tested hearing and found improvement i/e. approx. 40% less hearing. But when I completed defza-6 course, and hearing test shown that again it reverse back to 60% less hearing. My doctor suggerting to increasing defza-30, 1-dailly. Why it happen and what should I do now?
