As John said, there are also 1mg tablets and the tablets I've always gotten are scored in the middle which makes cutting them in half much easier. That was very important for me, as I had a hard time getting below the 10mg "hurdle". I had to taper a 1/2mg at a time to avoid flaring. As you get to lower doses it becomes very important to be able to adjust the dose by as little as a 1/2mg, as reducing the dose by more than 10% causes many people to flare. I've read that some have even reduced by .25mg although that has to be fun cutting pills by .25mg!
