How does Synthroid (thyroxine) affect sodium levels?

How does Synthroid (thyroxine) affect sodium levels?

Thyroid and sodium: There are many causes of abnormal na levels. Hypothyroidism can cause low na (hyponatremia). If you are on the correct dose of synthroid (thyroxine) (i.e. Normal tsh) then your na should be normal. If it is not, then another cause should be sought with the help of your doctor. ...Read more

I'm taking 200mcg of Thyroxine Sodium daily for the past 12 years. If I switch to 200mcg of Levothyroxine Sodium instead, What will be the side effect?

I'm taking 200mcg of Thyroxine Sodium daily for the past 12 years. If I switch to 200mcg of Levothyroxine Sodium instead, What will be the side effect?

Same thing: Hi. The only thyroxine sold as pure thyroxine is levothyroxine, so you should be fine. In other words, what was labeled as thyroxine was actually levothyroxine. After you make this switch, have your TSH and free T4 checked about 8 weeks later to assure biological similarity of the two different l-thyroxine preparations. Good luck! ...Read more

Thyroxine sodium vs levothyroxine. Which one is more effective?

Thyroxine sodium vs levothyroxine. Which one is more effective?

Stick with one: Thyroxine sodium and levothyroxine are simply different forms of generic "synthroid". Neither is better than the other. Whichever form you take, stick with it. The bioavailability of each thyroid preparation is a little different. If you switch from one form to another, your thyroid numbers may change, and you may start to feel hypo or hyper. Sometimes pharmacists switch you to save $. ...Read more

My FSH was more then 100 and I took levothyroxine 50 micrograms.. ..my doctor prescribed thyroxin and pharmacist gave me thyroxine sodium.

This question: Is a bit "confusing" do you mean TSH not FSH???? The thyroxine (thyroxin sodium is THYROID HORMONE which would be used to treat a high TSH!
Is that what you mean???
Hope this helps!

I would like to know why manufacturer's use levothyroxine rather than thyroxine in their thyroid medications? Levo has heavier sodium molecule

Thyroxine: 22M asks about diff between levothyroxine and thyroxine and notes Levo has heavier Na molecule. ANS: my recollection is that most Na is not of the heavy type. Recommend you look at the chemistry of Na at wikipedia for more details about heavy Na. ...Read more

My wife been diagonsed with hypothyroidism. She has been prescribed for sodium thyroxine. We are looking for that medicine from vegetarian source?

My wife been diagonsed with hypothyroidism. She has been prescribed for sodium thyroxine. We are looking for that medicine from vegetarian source?

It is vegetarian: All sodium levothyroxine is derived from vegetarian sources so no need to look any further. The only animal-derived thryoid medicines are thyroid glandular extracts like Armour Thyroid and nature-throid.
Most who are hypothyroid also benefit from liothyronine, which is also vegetarian- see http://thyroid. About. Com/od/t3treatment/tp/t4-t3-thyroid-treatment. Htm &

Female.46 years. Total thyroidtamy 6year ago. Using thyroxine sodium 100mg 2 tabs per day. Stopped that a month ago and TSH tested 4.60. what is then?

If you really had: A total thyroidectomy, you need thyroid replacement life long, however, 200 MICRO grams a day would be a relatively high dose. If your TSH is 4.6 after no replacement, your surgeon left in some thyroid tissue, but you still need BRAND NAME thyroxine replacement at an appropriate dose to keep your levels normal. ...Read more

I am hypothyroid and taking medication from past 15 years. Thyroxine sodium 62mcg. Can I use ground flaxseed? If not can I use flaxseed oil? Spirulina?

I am hypothyroid and taking medication from past 15 years. Thyroxine sodium 62mcg. Can I use ground flaxseed? If not can I use flaxseed oil? Spirulina?

With thyroxine: I'm not sure if you're wanting to take the listed supplements instead of thyroxine (no) or with your thyroxine (yes). Essentially, if your thyroid levels are in the good range, you can take anything that someone with a normally working thyroid can take. Because different docs have different opinions, it's always best to check with your own doc, and make sure s/he knows exactly what you're taking. ...Read more

Suffering from hypo thyroid taking 100mcg thyroxine sodium tabulates. I am 37 year old weight 82 kilo height 5ft10inch blood pressure 140/95 help me.

Not sure what: You need help with. Your blood pressure is high and needs treatment, however, people don't "suffer" from hypothyroidism, as it's very easy to treat and correct with brand name T4 replacement. Just have your doctor adjust the dose after testing every 6 weeks until the levels are consistently normal, then it only needs a once/year check. No suffering is required. ...Read more

Residual thyroid: If your TSH was 4.6 after being off thyroid hormone for 1 month, it is very likely that you have residual thyroid tissue that is making thyroid hormone. A thyroid ultrasound would be helpful to assess this. ...Read more

Friend had thyroid cancer, total thyroidectomy. 15 yr hi-dose Synthroid (thyroxine) as suppression. Kidney eGFR now 47, sodium 131. Any connection likely? Age 70

Friend had thyroid cancer, total thyroidectomy. 15 yr hi-dose Synthroid (thyroxine) as suppression. Kidney eGFR now 47, sodium 131. Any connection likely? Age 70

Not likely related: Hi. It is not likely the history of thyroid cancer and TSH suppression are related to the low eGFR or hyponatremia. eGFR falls with age, and hyponatremia is the most common electrolyte abnormality we see; both have multiple potential causes, but mild TSH suppression is not a likely one. Your friend can talk with his/her endocrinologist to see if there is any connection or needs further work up ...Read more

I have hypothyroidism. I take thyroxine sodium tablet early morning. I am having drowsiness and head ache all the day. What would be reason?

HYPOTHYROIDISM: HYPOTHYROIDISM can cause a myriad of symptoms. In women it can cause weight gain /fatigue/dysfunctional uterine bleeding resulting in a secondary anemia. I have better success with Armour thyroid and try to get TSH<1. Additionally Cytomel (T3) can be added. Also gluten free diet (WHOLEAPPROACH.

Why?: Why are you trying to eliminate salt? The body needs to stay in balance. Too much or too little of anything is not good. Check RBC magnesium as well as RBC potassium. You may need magnesium and potassium as well to keep things in balance. ...Read more
