Let me stress that it is not a good idea for you to be messing with your doses and skipping them without consulting your endo. The endo is trying to get you on a regulated dose, but your blood tests won’t be accurate if you’re adjusting your doses on your own.
I got a wicked rash from Tapazole that I couldn’t stand and my endo took me off of it, but I have a history of drug allergies, so it wasn’t altogether surprising. Disappointing, yes.
I’d strongly suggest that you call your endo and talk to him/her about the rash. Make sure you explain that you skipped a dose, too, so they know.
Good luck–I know the itching can be very aggravating.
