Then I did it. I blew her mind. I said, "I see by your profile that you still have many of the 50mcg tablets at home, is that correct?" She affirms that she has several in the bottle. So then, stupid me, I suggest she can use those up by taking 1 & 1/2 tablets of the 50mcg to use them up. She looks baffled. I confirm that she has 50mcg tablets at home. She says yes. I tell her if she was to take one tablet and half of another tablet that would equal 75mcg and she can use up her old medication before she starts in on the new bottle of 75mcg. She looks worried, confused, upset, and sad all at the same time. So I give up and tell her to just throw away the old bottle of 50mcg and start taking the 75mcg. She looks relieved and happy.
