My doctor just prescribed levocarnitine, liothyronine, and had me buy three vitamins otc. Side effects?

My doctor just prescribed levocarnitine, liothyronine, and had me buy three vitamins otc. Side effects?

Please ask your doc: Your doctor should already know the side effects of liothyronine, like hyperthyroidism which can cause both short term and long-term consequences. T3 measurements are not useful in terms of assessing underactivity of the thyroid, particularly as a total T3 independent of TSH and ft4. Don't know why the other supplements either - you need to discuss further with your doctor. ...Read more

Is liothyronine used as a weight loss aid?

Is liothyronine  used as a weight loss aid?

It should not be: It should not be used as a weight loss aid, but that does not mean that some people do not try to do so. It is not advised. Taking unneeded thyroid hormone can be harmful and can promote osteoporosis as well as strain your heart. I believe in eating properly to lose weight.

Hyperthyroid 5 years with toxic nodule pre hemi thyroidectomy supressed TSH elevated T4 T3 (liothyronine) 10 days post op TSH supressed low T4 T3 (liothyronine) am i hyper or hypo?

Hyperthyroid 5 years with toxic nodule pre hemi thyroidectomy supressed TSH elevated T4 T3 (liothyronine) 10 days post op TSH supressed low T4 T3 (liothyronine) am i hyper or hypo?

Difficult to answer: Since you're on ptu (propylthiouracil) which inhibits thyroid function and hormone production. Would have to know when and how much ptu (propylthiouracil) you've been taking and serial lab values to determine the answer. If your TSH is still suppressed, you're probably still hyperthyroid, but more or longer therapy w/ptu (propylthiouracil) may help. Methimazole may be safer than put. Think about radio iodine therapy w/your doctor. ...Read more

Is this dangerous ? Life threatening ? Help please

Hyperthyroid: Hi. You're hyperthyroid. At your stated age of 26, it's not life threatening, but my advice is always to treat it. As you can see from the numbers, yours is fairly mild (we see hyperthyroidism a lot more extreme), but it still places you at risk for an accelerated heart rate and irregular rhythm, and feely not-so-well in many ways. It could be one of several conditions. See an endocrinologist. ...Read more

Had free t3, t4, tsh, and CBC last wk. Learned i'm was running hyper, so cut my liothyronine in half & also heading toward thyroid flare. What's that?

You need to: Find a new doctor, and it shouldn't be you. First of all, there is no reason to take liothyronine, as it can be dangerous and is unnecessary. Don't believe what you see on the internet about free t3, so-called "wilson's syndrome", etc. It's all hogwash. Your doctor should be the only one who adjusts your medication, which should be brand name T4 only. ...Read more

Effects of liothyronine?

Effects of liothyronine?

Liothyronine is T3 (liothyronine): Liothyronine is the generic name for tri-iodothyronine, (t3 (liothyronine)). It is considered the active form of thyroid hormone, although all cells can convert T4 (the predominant product of the thyroid gland) into t3 (liothyronine). Can be used to replace thyroid hormone, but it is short-lived. This means it must be taken multple times a day, and gives levels which are constantly going up and down (not ideal, hard to adjust). ...Read more
