What are the side effects of levoxyl (thyroxine) hormone?

What are the side effects of levoxyl (thyroxine) hormone?

None: If the dose is appropriate, there should be no side effects of thyroid hormone replacement. The body does not differentiate a normal amount of thyroid hormone coming from your thyroid gland or from a pill. ...Read more

Hormone (Definition)

A hormone (from greek ὁρμή, "impetus") is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. Only a little amount of hormone is required to alter cell metabolism. In essence, it is a chemical messenger that transports a signal from ...Read more

Is a natural hormone like "armour" better to use than sythetics like levoxyl (thyroxine) or synthroid?

Is a natural hormone like "armour" better to use than sythetics like levoxyl (thyroxine) or synthroid?

Thyroid: It depends on the individual. Armour thyroid is different from the other two because it has T3 (liothyronine) and T4 in a 1:4 ratio. The other 2 only have t4. Your prescriber will look at your blood test and determine which medicine based on your levels are a best fit. ...Read more

Is thyroid hormone the same as thyroxine?

Is thyroid hormone the same as thyroxine?

Thyroxine is a type: The thyroid gland secretes two types of hormones: thyroxine (t4) and triiodothyronine (t3), but it produces T4 at much higher levels than t3. When treating thyroid hormone deficiency, your physician may prescribe levothyroxine (which is oral tablet of t4), liothyronine (oral formulation of t3), or combinations of such, or even dessicated (dried) pig thyroid as replacement therapy. ...Read more

My Synthroid (thyroxine) level was too high and I became a bit hyperthyroid. I am nursing, should I be concerned about extra hormone passing to my baby?

My Synthroid (thyroxine) level was too high and I became a bit hyperthyroid. I am nursing, should I be concerned about extra hormone passing to my baby?

Should be ok: Levothyroxine is excreted into human milk in small amounts. Levothyroxine, in replacement doses, is not expected to cause adverse effects in the nursing infant. Your doctor will adjust your dose to bring it into the normal range. ...Read more

Been having elevated BP since total thyroidectomy 3 weeks ago. Tsh was 17 and on Synthroid (thyroxine) 125. Will BP fluctuate until hormone levels stable?

Been having elevated BP since total thyroidectomy 3 weeks ago. Tsh was 17 and on Synthroid (thyroxine) 125. Will BP fluctuate until hormone levels stable?

Blood pressure: Problems are not caused by an underactive thyroid. Have your doctor look for other causes and treatments. Once the thyroid level is stable, make sure your doctor knows to keep it at a level appropriate for someone with thyroid cancer, not the usual normal range. ...Read more

What do you suggest if my thyroid stimulating hormone shows TSH 16 should I increase or decrease the thyroxine dose?

What do you suggest if my thyroid stimulating hormone shows TSH 16 should I increase or decrease the thyroxine dose?

Should be seen by: Endocrinologist-
Superficially, you need more thyroid hormone, but if taking your current dose incorrectly, ie: with other meds/ foods, just taking it correctly may normalize TSH and MD can more safely adjust medication dose than you trying to do so. ...Read more

I'm 27 year old male with a thyroid stimulating hormone level of 3.92 miu/l and ft4 (free thyroxine) of 1.3 ng/dl. Do I have a thyroid problem?

I'm 27 year old male with a thyroid stimulating hormone level of 3.92 miu/l and ft4 (free thyroxine) of 1.3 ng/dl. Do I have a thyroid problem?

Thyroid: I would need to know the free t3, (liothyronine) reverse T3 (liothyronine) and the tpo and tg antibodies to see if you are producing antibodies to your thyroid. The new level per the american academy of endocrinology lowered the upper normal for TSH to 3.5. ...Read more

Triiodothyronine : 0.76 ng/ml; thyroxine : 5.27 ; thyroid stimulating hormone : 1.15. Is this normal?

Triiodothyronine : 0.76 ng/ml; thyroxine : 5.27 ; thyroid stimulating hormone : 1.15. Is this normal?

Probably: In interpreting thyroid hormone levels, you have to consider several things: What is the clinical situation at the time of the lab draw- as stress, medications, even pregnancy can all effect the levels and what they should be. Every lab also has a slightly different 'normal' range depending on how they measure the hormone. Seeing the trend also helps - Are they stable, going up or down? ...Read more

Been taking synthroid (thyroxine) (125) for 6+ months and just discontinued. How long until TSH/thyroid hormones return to baseline levels?

You need synthroid (thyroxine): If you have been diagnosed with hypothyroidism and a physician has placed you on synthroid, (thyroxine) this is a lifelong replacement therapy. If the diagnosis was correct, your thyroid can no longer produce enough thyroid hormone and without the continuous thyroid replacement therapy (synthroid) you will eventually experience all the signs and symptoms of hypothyroidism. Talk to your Dr. Before stopping med ...Read more

Recent steady increase BOTH T4&TSH;other pit hormones elevated;hyper SX; poss TSH secreting tumor; should Synthroid (thyroxine) be stopped? Awaiting MRI.

How high is the T4?: If the T4 is twice normal and T3 (liothyronine) is also elevated, may stop the thyroid medicine, if not continue until the MRI report and decide. ...Read more

My thyroid test shows thyroxine 13.3 microgram %, tri iodo thyroxine 1.81 ng/ml thyroid stimulating hormone 1.8 uIU/ml. Is there any problem?

My thyroid test shows thyroxine 13.3 microgram %, tri iodo thyroxine 1.81 ng/ml thyroid stimulating hormone 1.8 uIU/ml. Is there any problem?

Thyroid tests: These appear to be normal values, but you did not provide the normal values: the normal range varies from one lab to another.
If they're normal, then you are not hyper or hypo thyroid. But why were these tests performed? This needs to be interpreted by whomever ordered these tests. ...Read more

I have irregular periods, taking thyroxine to keep thyroid stable, trying tcc, 1 yr no success my luteinising hormone level is 6.9iu/l what stage is?

Evaluation: Since it has been 1 year that you are trying to conceive and you have irregular periods you should undergo an evaluation by an obgyn or fertility specialist your lh level is normal but there are others tests and hormones that should be checked such as day 3 fsh, estradiol, amh, prolactin, thyroid function tests, pelvic sonogram and exclusions of other conditions such as pcos. ...Read more

I am taking sulfamethoxazole and spironolactone for acne, but still have active jaw line acne. Could Synthroid (thyroxine) help in balancing my hormones too?

I am taking sulfamethoxazole and spironolactone for acne, but still have active jaw line acne. Could Synthroid (thyroxine) help in balancing my hormones too?

Absolutely not: Synthroid (thyroxine) should only be taken in cases of hypothyroidism and under the care of a physician, NP, or PA Taking it would increase metabolism; I doubt that this would have an effect on your acne (it's a different hormone pathway entirely) and might make it worse. See your doc or dermatologist if still having probes w/ur acne. Best of luck! ...Read more

So the internist said it wasn't necessary for my mom to increase her synthroid (thyroxine) dosage of 25 mcg because she has active thyroid hormone (T3) of 2.9. Do you agree?

So the internist said it wasn't necessary for my mom to increase her synthroid (thyroxine) dosage of 25 mcg because she has active thyroid hormone (T3) of 2.9. Do you agree?

???: Usually we use TSH to titrate the synthroid (thyroxine) dose. There may be some confusion. Better double check with her internist.

Good luck, your mother will be proud of you. ...Read more

Failing thyroid: Most likely you have Hashimotos thyroiditis, which is gradually "eating away" at your thyroid. Your doctor could check TPO antibodies. Your gland may not be totally dead now, but it likely will be eventually, but total hypothyroidism and a dead gland could be in 3 months or 10 years. Probably best to take your synthroid (thyroxine) to avoid the symptoms of hypothyroidism, but talk to your doc. ...Read more

Production of antidiuretic (adh), thyroxine and t3, (liothyronine) parathyroid (pth), hormones of the adrenal cortex and the pancreas, can you tell me about this?

Production of antidiuretic (adh), thyroxine and t3, (liothyronine) parathyroid (pth), hormones of the adrenal cortex and the pancreas, can you tell me about this?

Complex: Please ask a specific question. This is way too complex and vague to answer. If you want to know about all these hormones, consider an Endocrinology fellowship at a major teaching hospital. Of course, before that, you will need a BS, an MD, and a 3 yr Internal Medicine residency. ...Read more

How can a hyposecretion of aldosterone and cortisol hormones lead to low blood sugar?

How can a hyposecretion of aldosterone and cortisol hormones lead to low blood sugar?

Gluconeogenesis: Hi. In prolonged fasting, cortisol plays an important role in a process the liver uses to make sugar from amino acids called gluconeogenesis. If glycogen (stored sugar) is depleted (happens in less than 24 hours of fasting), and the body cannot make enough new sugar from amino acids, low blood sugar can occur. Aldosterone does not play a role in gluconeogenesis. ...Read more
