Some patients notice an improvement in how they feel shortly after starting on thyroid med, but it doesn't last. . This is because the med starting dose is not additive to your prior levels. The med causes your TSH to go down, which in turn provides less stimulation to the thyroid gland to produce hormone. The net effect on serum levels is very little. Only when the dose is high enough to essentially suppress TSH, will further increases in med dosage start to raise your thyroid hormone levels and have a lasting effect on symptoms.
A word of caution though. Most doctors don't understand that our bodies normally get a continuous low flow of thyroid hormone in the untreated state, but when you take a significant dose of thyroid med all at once it spikes thyroid levels for a short time and suppresses TSH for the day. Most doctors don't know about this and will diagnose a suppressed TSH as hyperthyroidism due to over medication and will want to reduce the med dosage. You are actually hyperthyroid only if having hyper symptoms due to excessive levels of Free T4 and Free T3. Knowing this will prepare you for future situations with the doctor.
Even without knowing your new serum levels and the other tests, your symptoms are indicative of inadequate low thyroid, which I explained above. You need to increase your med dosage, and may even need to add a source of T3 to your T4 med. Most hypo patients taking T4 find that their Free T4 will eventually increase with dose increases, but due to poor conversion of T4 to T3, Free T3 is inadequate. Researchers have found that on average, even at higher doses of T4, symptom relief required Free T3 in the upper half of its range. A good thyroid doctor will diagnose and treat a hypothyroid patient based primarily on symptoms, supported with expanded testing that includes Free T4, Free T3, Vitamin D, B12 and ferritin. So you should make sure all of those are tested at next opportunity.
Regarding any effect from the antibiotic. There is some evidence that antibiotic can affect thyroid gland function and cause lower thyroid levels, but a lot of your thyroid hormone is coming from the med now. As for affecting the test itself I found this:
"Other medications can interfere with thyroid laboratory measurements, but not with the actual functioning of the thyroid.3
A few examples of these medications include:
Certain nonsteroidal anti-inflammatories (NSAIDs)
Certain anti-convulsants
Heparin (a blood thinner)
Lasix (furosemide)
Glucocorticoids
Isotretinoin
It didn't mention antibiotics, so I would not be concerned about it and go ahead and get the tests listed above done.

My results are below:
Free T3: 2.31 (Ref range: 1.7- 4.2)
Free T4: 0.84 (Ref range: 0.75- 1.56)
TSH: 0.856 (Ref range: 0.55- 4.78)
CBC results:
RBC show mild microcytosis and anisocytosis
Mild relative lymphocytosis
Mild absolute neutropenia
My doc refused at any case to increase my dose as he told me that my TSH is perfect and any increase in dose will make me hyper.I told him that my Free T4 is in the floor of its range but he dose not seem concerned.Also he said I had anemia and need iron supplements.What do you think about my thyriod tests and CBC.Should I increase my dose to alleviate my symptoms or this will made me hyper?. If not ,how much can I increase? Can I increase by 12.5 mcg?
What test results made the doctor say you need iron supplements?
Let's make sure that no symptoms are overlooked. Please review the following list used by the Mayo Clinic and tell us which ones you have. Then I will have suggestions for your next appointment with the doctor.
Fatigue
Increased sensitivity to cold (temp. below 98.6 which is considered normal)
Constipation ( had to use fiber or laxatives before you had surgery)
Dry skin (have to use moisturizer)
Weight gain (you previously had this problem, so it is a yes)
Puffy face (I think you had this problem before surgery, but hard to notice now with your weight loss)
Hoarseness
Muscle weakness
Elevated blood cholesterol level
Muscle aches, tenderness and stiffness
Pain, stiffness or swelling in your joints
Heavier than normal or irregular menstrual periods
Thinning hair
Slowed heart rate
Depression
Impaired memory
Enlarged thyroid gland (goiter)
insomnia/sleep apnea
Sorry, I copied a list of symptoms I used for someone else, with my comments. Here, I'll try again. Please tell us about any of these you have.

Not by any stretch is that a complete list of hypothyroid symptoms. It is just some of the most typical ones. Your symptom of diarrhea could be due to a number of possible causes. Is this something that has occurred only recently? Do you have any of the following additional symptoms?
extreme fatigue
weight loss and decreased appetite
darkening of your skin
low blood pressure
salt craving
abdominal pain nausea, diarrhea or vomiting
muscle or joint pains
irritability
depression or other behavioral symptoms
body hair loss
With your symptoms and your test results, it is obvious to you and us that you need an increase i your thyroid medication. To get the doctor to do this is the problem because he doesn't understand how TSH is affected by taking a significant dose all at once instead of the continuous low flow of thyroid hormone in the untreated state. I think you have to ask him if your TSH is perfect why do you still have all those symptoms that are typical of hypothyroidism, and give him a list of all symptoms that you have. Then tell him that there is extensive scientific data showing that typically when taking a full daily replacement dose all at once, adequate to relieve symptoms, the TSH becomes suppressed; however, that does not mean hyperthyroidism, unless you have hyper symptoms due to excessive levels of Free T4 and Free T3. I have a study showing that when a dose of thyroid med that causes suppression of TSH, is split into thirds and taken over the entire day, instead of all at once, it will raise the TSH by about 2. So TSH suppression is usually caused by the dosing procedure being so different from the normal low flow of thyroid hormone, not the dose amount. I can give you a copy of this by email, if you want it for your doctor. I can also send you a copy of a graph showing the effect of Free T3 on the incidence of hypothyroid symptoms.
I also suggest that you click on my name and then scroll down ot my Journal and read at least the Overview of my paper on Diagnosis and Treatment of Hypothyroidism: A Patient's Perspective. It will be very useful info for you, and a copy for your doctor might get him to reconsider his decision about dosage.
Those symptoms are from the Mayo Clinic's list of symptoms typical of hypocortisolism. Low cortisol is a common problem for women with hypothyroidism. The best way to test for it is a saliva cortisol (free cortisol) panel of 4 tests taken at different times of the day. Doctors usually will not order saliva cortisol tests. Instead they will run a morning serum cortisol (total cortisol) test, which is not nearly as revealing as the saliva tests. In either case the reference ranges used by labs are likely to be calculated based on all tests at the lab. Since they have no ready method for identifying only healthy adults with no cortisol pathology, the ranges are far too broad and especially skewed to the low end. So with those symptoms if your cortisol test results are in the lower half of the range it is worth a conversation with the doctor about a trial of cortisol med.
When are you scheduled for followup tests and an appointment with the doctor?
Cortisol is a type of steroid; however I can't imagine trying to reduce inflammation from Hashi's by using a steroid. The correct approach would have been to use thyroid medication adequate for a full daily replacement amount. That would have reduced the antibodies of Hashi's.
Your body produces steroids all day. If your production is too low that causes problems and requires replacement. Thyroid hormone needs to be somewhat balanced with cortisol. Cortisol needs to be somewhat balanced by DHEA. If it turns out that you need cortisol then you should not be concerned about a trial of hydrocortisone (and DHEA). This is a natural approach. Taking an adrenal support is unlikely to achieve the desired result. For example, how much would you need and what is the actual effect of all that is in the supplement? Much better to rely on actual cortisol (and DHEA).
I am also sending you a PM. To access, just click on your name and then from your personal page click on messages.
Prednisone is a lousy steroid because of the side effects. You can get the same good effect with hydrocortisone, and prevent unwanted side effects by also taking DHEA.
