I went to pick up my thyroid medication which I have been taking for about fifteen years. There was a red sticker on the thing I'm supposed to sign. It said not to take anything with calcium, iron, antacids, for four hours after taking the thyroid medication. I have been taking my calcium tablet about an hour after the thyroid pill.
When I got home I looked to see if that warning is on the pill bottle itself. It isn't. It was on the thing I signed and returned to them.
I don't know if it has been there all along and I haven't noticed, or if it started showing up when somebody else picked it up for me and signed for it.
That is annoying.
