I think that taking the time to track yourself and learn where you feel best and compare that to dosages and labs is best to know if you and your doctor should adjust or wait.
What I mean by "knowing" is so many get caught up in the phrase - " Well the doctor knows best!" - when in erality you are the best knowing if you still feel bad and you should have a working relationship with the doctor on him/her listening to you on your feelings.
So many in England find the TSH is used only and if you really want to know best - get the Free T3 and Free T4 lab done and track those with symptoms. You can find quicker result in "normal" thyroid situations better than basing it all on the TSH.
Maggie - I read a few posts and you seem eager to talk about thyroid storming. Its a rare situation and yes it shows concern but there is a process leading up to storming in almost all thyroid cases. Its best to watch from the beginning and know our bodies so storming isn't an issue.
YOU CAN END UP IN THYROID STORM,WHERE EVERYTHING IN YOUR BODY WILL SPEED UP HEART RATE, TEMP.iT IS NOT SAFE TO EXPERIMENT WITH MEDICATIONS,YOU WILL DO MORE HARM THAN GOOD.KEEP GOING BACK TO YOUR DR AND REQUEST MORE BLOODWORK.EVENTUALLY THEY WILL GET YOUR LEVEL AT A CORRECT DOSE.PLEASE BE CAREFUL.
Oh trust me - I can relate!!!! You really do need to increase slowly and let things happen over time. I know waiting can be frustrating but it's better than the alternative, drug induced hyper from increasing too quick is NOT fun at all, I've been there twice.
But in time, you will get there, you and your doctor will find the right dosage for you and then you will feel better. It just takes some time to find the correct dosage for you.
All any of us can do is increase SLOWLY with the doctor when needed and just try to keep positive (and sane) in between those times.
PM me if you want to chat - by the sounds of your post I feel exactly like you do right now (except I dont have a child and Im only 19 - only differences lol)
Most of us can probably relate...undermedication is probably the single complaint we hear about most on this forum.
Of course, if you take too much thyroxine and become hypER, you could die. HypER is a more dangerous condition than hypo as it stresses the heart especially, but many other organs as well. So, it's nothing to play around with, but that doesn't mean you should be undermedicated "just in case". I doubt too many patients have succumbed to overmedication lately, especially as stingy as doctors tend to be with it. You can hit a happy medium...it just takes a little work and a little understanding of what lab ranges mean. Each of us has a different place in the range at which we are comfortable and symptom-free. For some it's low in the range, some midrange, some high. Doctors have to increase meds until all symptoms are gone. Sometimes that even requires getting numbers slightly above or below range (but don't tell your doctor that...it'll scare the living sh/t out of him! LOL).
Do you have FT3, FT4 and TSH levels to post along with reference ranges? Was your dose recently changed to 100 T4/ 2.5 T3? What was it before? Do you know if you have Hashi's?
