First, I want to say that we are not doctors in this forum, only fellow patients who try to help others through our own personal experience.
It is not recommended to split synthroid pills even that they have a score, because of consistency issues.
Did your doctor tell you by how much to increase?
from 25 to 50 this is 175 mcg /week, which is much more than your TSH allow, you definitely need to increase your dose, but , only by 50 mcg per week ,aka , add 50 to one day so that you take 25 mcg for six days and then in the seventh take 75 !
Again this is according to my own personal experience with TSH, call your doctor and ask for his confirmation !
