Members have reported headaches when raising dose but they usually subside within a couple of weeks.

If you are unable to comfortably tolerate 75mcg to 100mcg dose increase try 75/100mcg alternate days. Sometimes a very fine adjustment is all that's required.


I have tried 75,75,100 and still got sinus and headache problems ,am trying 75 at bedtime and take 25 in the morning just for one morning a week to see how it goes ,maybe cutting a 25mg tab might work for me a few mornings a week , not sure why my sinus are sore .
