I have no idea about all the ins and outs of Synthroid vs. Armour. I know that people sometimes have better results with one and then sometimes the other. In my case I found that even though taking a large dose of Synthroid (200mcg), I never became symptom free because my body was not converting T4 very well. When my doctor confirmed this by checking free T3, she decided to change my meds to a T4/T3 combination. I started feeling better very shortly thereafter. The key point is to make sure you always know the free T3 level.
Interestingly, after prescribing Armour for me, my doctor received a letter from the insurance company, basically questioning why she would ever prescribe Armour, when there was no evidence that it had any benefit over synthetics such as Synthroid. LOL
Have had low thyroid for all of my adult life, and have been prescribed most of what's been available. Much prefer my overall state on Armour. Less pain, especially in back, hands and wrists; general well-being must be better, because it doesn't shout as loudly for my attention as it did on the drugs; have greater mental clarity; on the whole, not as depressed as while on the drugs. Much prefer the Armour. However, taking a poll can only guide you initially. Each of us is different. If what you and your doc first decide upon works well for you, search no further. If it's a struggle to exist while you're taking forever to improve, then consider the other options. Whenever I would be forced into a transition to another drug by a hard-headed white coat, I'd feel pretty exasperated, but the transitions from the drugs to Armour has always been a lot smoother as ea day passed. Some professionals feel that the consistency of dosage in Armour is a problem, and, in fact, I understand that it's been outlawed in Australia. My holistic dr just laughs and shakes his head when anyone brings up that point. I'm sort of in Shakespeare's camp: "Much Ado About Nothing"---if it was ever a legitimate problem, don't think it is now. Has never been a problem for me; it's always been my best solution.
I am waiting for my numbers now. When I ask for a T3 the doctor said my insurance may not cover that. I didn't pay for it and the insurance did pay it. I will reply when my numbers arrive. I know my TSH was under 1 because we have been working to get there for 9 months. Thanks for your reply
Please post the actual numbers and reference ranges from your last couple of blood tests. It will help if we can see what tests were run and where the results fall within the reference range. What kind of symptoms are you still having? Your remaining symptoms could be related to the thyroid levels achieved with your current medication, rather than needing to change to another. Let's look at the test results first.
