I'm with Allergicto here. To derive the very best from any medication is to take it exactly as prescribed. All medications works to reduce your tsh because your body is not scavenging about for what it needs. If you were taking your 150 mg Armour every other day effectively your dose is 75mg, if it were less frequent obviously the effective dose would be less too, so your tsh would be higher. I would be doing my body a disservice were I to be irregular with my medication. Any medic can only assume you are taking the amount you are prescribed. From the numbers you provided the Amour is not serving you well, though it is probably your lack of commitment to your treatment which is failing you based on guess work.

Do you know if your Hypothyroidism is because your thyroid function is low or do you have thyroid antibodies which would make the condition Hashimoto's Thyroiditis? (The body for some reason best known to itself, there are many, produces antibodies to your thyroid because it confuses it with something which should not be present). Many primary care providers do not test for antibodies. Here in the UK we have a one size fits all treatment regime for all hypothyroid situations, synthetic unless you are able to go private or find a someone on the NHS brave enough to listen. Many here (MFP) would give their eye teeth to have the treatment you are supposed to be on. (I know lack of finance can be a driving issue)

It is possible the t3 in your Amour will be being more beneficial to you if you have Hashi because Hashi particularly comes with a difficulty turning t4 the precursor into t3 the active form because of the antibodies. Without antibodies there are a different set of problems. Armour, a natural product also has t1 and t2 which also play a part in thyroid function but as yet are not quantified. Knot knowing everything about you I do not think I would rush too much to take levo or similar because it is t4 only. Were the synthetic the Endo had in mind synthetic t3 this might just be different.

You say you are seeing a Naturapath in August. Your preferred treatment option. You have done your research into this person. I think, putting myself into your position, I would take the Amour daily as prescribed. Hold out till this appointment, be prepared for more blood letting for probably a full thyroid panel to achieve your most appropriate results. Then take life from there.

A word of warning. Suddenly putting yourself back up to the 150 mg of Amour particularly if your average is less than 75 mg you may find yourself with some hyper reactions because your body is not used to it. Keep a record from now so you know what your are doing and note any changes you experience so your information is spot on for your new Naturapath. Please read up on Hyper reaction so were the worst to happen you know what is going on and seek proper medical advice. Then please, think well about how you see your future. All the best.

If that were a typo, and you're on 150mcg Synthroid, I'd still say the same thing: take your meds! Synthroid (levothyroxine) is synthetic T4, which the human body can convert to T3.

Synthetic may not be as "good" as NDT, but it's still 100x better than being unmedicated.
