Armour Thyroid is the brand name for a natural desiccated thyroid extract used to treat hypothyroidism. Hypothyroidism occurs when the thyroid gland is underactive. Usually made from the thyroid glands of a pig, Armour Thyroid works by replacing the hormones that your thyroid gland is unable to produce. The level of hormones can affect many different body functions causing potential imbalances.
These side effects are not common. Usually, they mean that your dose is too high and needs to be lowered. If your doctor is considering starting you on Armour Thyroid for your hypothyroidism, let them know about any prescription or nonprescription drugs or supplements that you take regularly, including:. Armour Thyroid is typically taken orally once daily. The dosage requirements are usually individualized based on patient needs.
Dosage is usually low at the beginning of treatment so that your body can become accustomed to it. Select personalised ads. Apply market research to generate audience insights.

Thyroid hormone replacement drugs are used to treat hypothyroidism —a condition in which your thyroid gland does not produce enough thyroid hormones.
When you take the proper dose of these medications, they are safe, with few side effects. If you are taking too high a dose, however, you can experience unpleasant symptoms.
This is known as overmedication. This article discusses the causes and symptoms of thyroid hormone replacement overmedication. Levothyroxine is a type of thyroid hormone replacement drug that is often used to treat hypothyroidism. Brand names for levothyroxine include Synthroid, Levoxyl, and Tirosint.
Natural dessicated thyroid NDT is also used to treat hypothyroidism. For some people, NDTs work better than levothyroxine, and many people prefer them because they are considered more natural. Usually, people begin thyroid hormone therapy with a low dose that is gradually increased. In part, this is because hypothyroidism progresses over time. But starting therapy with a low dose is also helpful for reducing the risk of overmedication.
This video has been medically reviewed by Rochelle Collins, DO. Signs and symptoms of thyroid hormone overmedication can vary. Some common symptoms include:. In some cases, symptoms of overmedication can be similar to those of hypothyroidism. You may feel more exhausted than usual, or achy and as if you have the flu; you may put on weight, or feel jittery and anxious.
In fact, it's not unheard of for a person to visit their healthcare provider to get tested, certain that they need an increased dosage, only to discover that their symptoms are actually due to overmedication.

There are a number of ways you can become overmedicated with your thyroid replacement drug. Sometimes, it takes trial and error to get your dosage just right. Prescribing mistakes can happen as well. It does not sem to be enough. It kind of depends on what you were feeling when your dose was too high. It may not actually have been too high. Ihave had the issue since starting thyroid meds yrs ago. I was diagnosed 6 weeks ago. Yes I have been working up and now at No I am still running body temp around 96 degrees and freezing all the time.
I am very sensitive to thyroid meds. They make me speed. I have plenty of energy. I was on 60 mg of armour, it was too much. I was cut cut down to I am now taking a little under My recent blood work my t 4 was low other levels were normal.
I am in the process of fin a G P mine retired. The one i went too was totally wrong on my dose. Childs, I was diagnosed hyper with hot nodules and had RAI that made me hypo in As a result, my hypo symptoms along with my cholesterol, triglycerides, and sugars sky-rocketed despite a healthy lifestyle, and while going through severe life stress I had a heart attack in at age After that, struggling with debilitating side effects from heart and cholesterol meds, I found a functional med dr willing to listen to my symptoms, switch me to higher dose of NP thyroid, and manage my heart disease naturally.
I grew healthier and stronger but still struggled with weight gain, fatigue, and hair loss so he slowly upped my dose to a total of mg of NP split 2Xs per day. My labs 3 hours after my morning dose were: TSH. But I already feel awful. Most of what I read says an abnormal heartbeat is a sign of being over-medicated, but it makes no sense since it started happening after lowering the dose, and I feel so hypo.
Have you ever seen symptoms that appear so reversed? Is she right about taking time to adjust? Thanks much! I have a general question for you. I get these daytime fatigue naps around pm. My labs showed me low on 2. I am going to do labs again at 5 weeks. My question is, do you ever see people on 3. Just seems a little unusual since the clinical paperwork on armour says most people will need grains with 3 being the exception and im talking 4…….
I had my thyroid ablated about 20 years ago. I was put on NP Thyroid 2 grains and it was perfect then they changed the formulary and went to Armour Thyroid. And felt great. Since switching to Armour I experience infrequent brain fog.
I need to get my FT3 higher. Childs Your website is wonderful and a great reference. I started seeing an endocrinologist in February of this year. I felt like a lawyer pleading a case to the endo. She finally consented to try me on a low dose of med and I asked to try Armour. The Armour has gotten my TSH down to. All thyroid labs done this year have my Ft4 at 1. I feel terrible. I messaged my endo doc and questioned maybe trying a T3 med. She has mentioned that if we would ever go that route, she does not give an NDT with a T3 at the same time.
Really not sure if that is the route to go. Getting desperate to feel better!! Would you ever combine Armour 60mg with a T4 only like Levo at a low dose med? I have been on levo for 20 years, on different doses, up and down, depending upon if I am pregnant or not.
My last dose was mcg. I tried Armour for the first time about weeks ago at 60 mg because of conversion issues.
No side effects which was a relief as I am very sensitive to meds. So doc increased me to 90mg to give my body more T4. Anxiety came, hot flashes, mood swings, loss of appetite. I finally put two and two together to realize I was having side effects from the higher T3 in the Armour.
I feel soooo much better having gone back down to 60mg. But clearly my thyroid needs more support. Wanted to run this by you before I asked my doc about it. Thank you! Hi I began using armour last year.
Recently I have begun to feel a little more sluggish and tired in the afternoons. Do you think I need to increase my dose? I am currently taking 45mg daily. Hi, Been on armour for a year, increased dose recently to 30mg and my TSH came down some as did my T3 and T4 going up to 45mg and having levels checked in a few weeks. Is it common to have TSH come down on therapy as well as decrease in T3 and T4, and if so does this indicate the need to increase my dosing?
I have Hashimotos, just got switched from Nature Throid due to recall to Armour. My TSH has been decent for years 1. Should I have other test? This has been going on for years. Not sure if I need to just up my dose, or have other test done? Thanks for any insight. The only difference between the two is that I started to suffer swelling of the face and extreme fatigue on the 1.
My skin felt hot yet body temp was normal. TSH was. Went back down to 1. The next day I went back to 88mcg of Levo and all the swelling went away. Tried to add T3 to a lower amount but there does not seem to be any amount of T3 that compensates for low T4 levels. Convinced her to try me on Armour.. Hello Dr. Childs, I left a comment a couple years ago when I was first dx with Thyroid cancer.
Most recent values I just received post thyrogen and scan are: TSH is Would it be unreasonable to ask my endocrinologist to increase my Armour Thyroid to mg?
And if this is ok to ask, what I mentioned to you, is that statement enough to make me not look like I just want it raised but have a valid reason for this request? I obviously need a higher dose but last time I took I started having bad hyper symptoms. Those labs came back low TSH 0. I was having the worst insomnia ive ever had, anxiety, jittery etc. I take Armour, only because Naturethroid is no longer available. SHBG is very high. I take HRT, progesterone and estradiol, but still suffer from hot flashes and night sweats.
My thyroid tests do not add up. I see a hormone specialist who says the sex hormones have to be good before the thyroid hormones will work. The only way my TSH is ever in normal range is when T3 is at low end of range. I have no thyroid. Any ideas? I have been taking NDT for years. But after Nature-throid was recalled, this past year have tried 2 other NDTs and after 6 weeks or so started getting hyper symptoms.
I recently switched from Unithroid to Armour. I started out with 15mg once per day for 4 weeks and it brought my TSH down from 7 to 4. Then I was raised to 30 mg once per day for 4 weeks and it brought my TSH to a 5 kind of weird that it increased. So I am thinking that I am now taking too much. I will talk to my doctor about this. I should ask my doctor if this indicates that I need to stay with the 30mg dosage and maybe a couple times a week increase the dosage by 15mg and see if this will lower the TSH?
Any thoughts on how I should approach this with my doctor? Are you currently taking Armour thyroid but not sure that your dose is where it should be? Are you thinking about switching medications but not sure if Armour is right for you? If so, this article is for you. Article highlights: Armour thyroid dosing is highly individualized and each person will need a different dose. Several factors influence the dose that you will need.
The average dose is somewhere between 60 mg 1 grain and mg 2 grains per day. Sensitive individuals will need doses smaller than 60mg while resistant individuals may need a dose higher than mg. The best way to find your optimal dose is through lab testing and closely following your symptoms. Many patients are underdosed when converting to Armour thyroid from other thyroid medications.

The Complete List of Thyroid Lab Tests: This list includes optimal ranges, normal ranges, and the complete list of tests you need to diagnose thyroid hypothyroidism correctly! And, believe it or not, it's not always as straightforward as you think.
First off, what is Armour thyroid? Each Person is Different So is your dose! Dealing with Sensitivities Even though Armour thyroid may be the right medication for you, you may not tolerate traditional doses. What do I mean? The higher affinity of levothyroxine T4 for both TBg and TBPA as compared to liothyronine T3 partially explains the higher serum levels and longer half-life of the former hormone.
Both protein-bound hormones exist in reverse equilibrium with minute amounts of free hormone, the latter accounting for the metabolic activity. Deiodination of levothyroxine T4 occurs at a number of sites, including liver, kidney, and other tissues. The conjugated hormone, in the form of glucuronide or sulfate, is found in the bile and gut where it may complete an enterohepatic circulation. Eighty-five percent of levothyroxine T4 metabolized daily is deiodinated.
As replacement or supplemental therapy in patients with hypothyroidism of any etiology, except transient hypothyroidism during the recovery phase of subacute thyroiditis.
This category includes cretinism, myxedema, and ordinary hypothyroidism in patients of any age children, adults, the elderly , or state including pregnancy ; primary hypothyroidism resulting from functional deficiency, primary atrophy, partial or total absence of thyroid gland, or the effects of surgery, radiation, or drugs, with or without the presence of goiter; and secondary pituitary , or tertiary hypothalamic hypothyroidism SeeWARNINGS.
As pituitary TSH suppressants, in the treatment or prevention of various types of euthyroid goiters, including thyroid nodules, subacute or chronic Iymphocytic thyroiditis Hashimoto's , multinodular goiter, and in the management of thyroid cancer. Thyroid hormone preparations are generally contraindicated in patients with diagnosed but as yet uncorrected adrenal cortical insufficiency, untreated thyrotoxicosis, and apparent hypersensitivity to any of their active or extraneous constituents.
There is no well-documented evidence from the literature, however, of true allergic or idiosyncratic reactions to thyroid hormone. Drugs with thyroid hormone activity, alone or together with other therapeutic agents, have been used for the treatment of obesity. In euthyroid patients, doses within the range of daily hormonal requirements are ineffective for weight reduction. Larger doses may produce serious or even life-threatening manifestations of toxicity, particularly when given in association with sympathomimetic amines such as those used for their anorectic effects.
The use of thyroid hormones in the therapy of obesity, alone or combined with other drugs, is unjustified and has been shown to be ineffective. Neither is their use justified for the treatment of male or female infertility unless this condition is accompanied by hypothyroidism.
As a result, a potential risk of product contamination with porcine and bovine viral or other adventitious agents cannot be ruled out. Forest is not aware of any cases of disease transmission associated with the use of Armour Thyroid. General—Thyroid hormones should be used with great caution in a number of circumstances where the integrity of the cardiovascular system, particularly the coronary arteries, is suspected.
These include patients with angina pectoris or the elderly, in whom there is a greater likelihood of occult cardiac disease. In these patients therapy should be initiated with low doses, i.
When, in such patients, a euthyroid state can only be reached at the expense of an aggravation of the cardiovascular disease, thyroid hormone dosage should be reduced. Thyroid hormone therapy in patients with concomitant diabetes mellitus or diabetes insipidus or adrenal cortical insufficiency aggravates the intensity of their symptoms.
Appropriate adjustments of the various therapeutic measures directed at these concomitant endocrine diseases are required. Hypothyroidism decreases and hyperthyroidism increases the sensitivity to oral anticoagulants.
Prothrombin time should be closely monitored in thyroid-treated patients on oral anticoagulants and dosage of the latter agents adjusted on the basis of frequent prothrombin time determinations. In infants, excessive doses of thyroid hormone preparations may produce craniosynostosis. Information for the Patient—Patients on thyroid hormone preparations and parents of children on thyroid therapy should be informed that:. Replacement therapy is to be taken essentially for life, with the exception of cases of transient hypothyroidism, usually associated with thyroiditis, and in those patients receiving a therapeutic trial of the drug.
They should immediately report during the course of therapy any signs or symptoms of thyroid hormone toxicity, e. In case of concomitant diabetes mellitus, the daily dosage of antidiabetic medication may need readjustment as thyroid hormone replacement is achieved.
If thyroid medication is stopped, a downward readjustment of the dosage of insulin or oral hypoglycemic agent may be necessary to avoid hypoglycemia.
At all times, close monitoring of urinary glucose levels is mandatory in such patients. In case of concomitant oral anticoagulant therapy, the prothrombin time should be measured frequently to determine if the dosage of oral anticoagulants is to be readjusted.
Partial loss of hair may be experienced by children in the first few months of thyroid therapy, but this is usually a transient phenomenon and later recovery is usually the rule. Laboratory Tests—Treatment of patients with thyroid hormones requires the periodic assessment of thyroid status by means of appropriate laboratory tests besides the full clinical evaluation.
The TSH suppression test can be used to test the effectiveness of any thyroid preparation bearing in mind the relative insensitivity of the infant pituitary to the negative feedback effect of thyroid hormones. Serum T4 levels can be used to test the effectiveness of all thyroid medications except T3.
