@deanna14. I have been on for 8 month, 10mg. For first. 3 months then 25 mg. I had a doozie of a flare in early July but I came out of it faster, ie instead of 4 weeks. I was out in 2. I was told not to take anything that would suppress the cough so I increase my water and suck on pectin drops (ludens). Take care
