What formulation of Levothyroxine are you on? 300mcg sounds like rather a lot. Have you had a thyroidectomy? Do you live in the UK? Have you been tested for thyroid antibodies and do you know if you have Hashimotos thyroid disease or not?


Yeah live in the UK, no not removed and on levothyroxine, not sure what brand! Never had my thyroidantibodies checked, literally only had my T3 done after requesting forever. I'm waiting an endo appointment (over a year now) so waiting to see what that brings up! Been underactive for 7 years now! It's frustrating


300mcg sounds like a lot so perhaps you are not absorbing it well. Are you taking levothyroxine 1 hour before eating anything with a whole glass of water. Do you take any other supplements? If so, do you take them at least 4 hours away from Levo? Have you asked your GP about absorption problems? Have you got Hashimotos and have you had your thyroid antibodies checked? Do you keep your Levothyroxine at room temperature and protect from heat?


Your GP can test for thyroid antibodies you don't have to wait to see an Endocrinologist.


on levothyroxine, not sure what brand

It isn't a good idea for people to switch brand all the time. Take a note of which brand of Levo you are currently taking. (I'm assuming it is just one brand you take rather than a mixture.) Note down your symptoms.

Next time you get a prescription for levo phone round a few pharmacies and ask which brand of Levo they would supply to fill your prescription. There are 3 or 4 different brands of Levo available in the UK. It would be worth trying them all (but don't mix brands from the same prescription) and note symptoms with each brand. You may find that one brand makes you feel better than the others. If that is the case you could ask your doctor to prescribe that specific brand for you, and then the pharmacist would be obliged to provide it.

To see the brands available, go to this link : medicines.org.uk/emc/

and do a search for levothyroxine.
