I have currently been on letro to treat pre existing gyno for about 10 days now. My last dosage was at 1.25mg. I read various threads saying it wasn't worth going up to 2.5mg. My gyno has decreased but it is definitely not gone. When do I know I need to up the dosage? I was thinking of staying at 1.25mg for about three or four days. Should I up the dose or stay? Thanks.
