We had the same problem when my 7 month old daughter was switched from the liquid to the pills. The endo decided to increase her dose the amount necessary for the pills. I sure do hope that they start making a 1mg or 2 mg pill in the U.S. I hear they are available elsewhere so why not here? Very frustrating. Good luck and be glad there is no more liquid cortef as it didn't work consistently for most and there were many problems. Good luck!
