I was diagnosed as hypothyroid when I was 6 weeks pregnant. I have been taking Levoxyl for about 2 years. Recently my dosage went up from 75 to 100 MCG. Since then my mouth is so dry, that I am always Thirsty. Worse- I am getting cavities because my mouth isn't producing enough Saliva. I was checked fo Sorjends, but am thankfully negative. Does anyone else have Dry mouth because of Levoxyl? I am not taking any other drugs..and all my Doctor says is "drink more water"
