On 50 mcg, I experienced very dry mouth. When I went up to 100 mcg, I felt the dry mouth got much better but not completely resolved and also insomnia was much better. I've been on as high a dose as 300 mcg but that didnt fix the issues. Im down to 188 mcg and it feels about as bad as it was on 50 mcg...Im thinking to try a combo of t4 and t3. Maybe 125 mcg T4 and 30 T3. The dry mouth was much better near 100 mcg T4. Plus I heard someone on here who switched from T4 to T3 and the dry mouth resolved. Any thoughts or experiences would be much appreciated.

Dry mouth and insomnia on levothyroxine
You've posted thyroid results, but many hypo people suffer from low vitamin levels which can result in a host of unpleasant symptoms. Do you have any test results for ferritin, folate, B12 and D3?
Thats true. My D3 is good now, B12 was like 443, range (200-1200). I started supplementing with methylcoblamin and methylfolate and it seems to help a lot with energy, but dry mouth and insomnia still there. Never tested folate...I have too much ferritin as I just recently learned I have heriditary hemachromatosis...Im experimenting with other supplements now. Coq10 doesnt seem to help. Ive tried 600 mg and dont feel anything yet. It was shown to increase saliva flow in a few experiments. No luck yet. Maybe try sea buckthorn next. Dont know. Thanks for responding
Have also had terrible dry mouth on T4 only.
Agree with your hypothesis on T3.
I had repeat salivary gland infections caused by dry mouth at the start of this year. I wondered if any of it was to do with sugar or glucose intake, too, as it happened after Xmas and eating a lot of food.
I had a very dry mouth for years before Dr P suggested I should stop t4 and start t3. Along with many other symptoms that go along with Hypothyroidism I was very ill. However almost as soon as started the new regime I began to feel better and have been now for some years. I do have to go to Greece to buy T3 as I have never ever been able to see a endo and my GP doesn’t want to know . I have managed at last to get a T3 blood test from my surgery now which is a minor miracle. I would never ever go back onto T4 as it was killing me. Because I was ‘starved’ of T3 because of non conversion I had a total heart block because of heart damage and now have a pacemaker. Why doctors and endos don’t realise the danger of non conversion I have no idea, it would help 1000s of people if doctors were better informed. Good luck
