If i double my dosage of levothyroxine, would i lose weight?

If i double my dosage of levothyroxine, would i lose weight?

Not a good idea: A high dose of thyroid will increase your metabolic rate, but also your appetite. Will also raise your heart rate, give palpitations, stress your heart, make you hot all the time, anxious, and much more. In the medical field, this would be a clear misuse of the medication. ...Read more

Does generic of Synthroid (levothyroxine) disperse the dosage equally throughout pill. I'm on 75mcg so if i cut in half will i get 37.5mcg?

Does generic of Synthroid (levothyroxine) disperse the dosage equally throughout pill. I'm on 75mcg so if i cut in half will i get 37.5mcg?

It's not the: Cutting in half that's a problem, as even if the cut is uneven it won't matter since the half-life of T4 is 7 days and the doses will overlap. The problem is that the generics aren't as reliable and the dose and potency will vary every time you get a new prescription, or the pharmacy changes suppliers, or with age and storage of the rx, etc. It is better and safer to stick w/brand name t4. ...Read more

My tsh was 11.46 in September, 3.37in December & 19.95 today. I am on levothyroxine 50 mcg & take medicine everyday. What would be my correct dosage?

11.46, 3.37, 19.95: That is an unusual set of numbers. I presume your doctor has been ordering TSH levels. What I don't understand is why comments are not made regarding the wide range of TSH in 4 months. Do you have any symptoms while taking levothyroxine? I may be missing something or it might be time to see another doctor. Please let me know how things go. ...Read more

I don't understand why I need less levothyroxine after removal of my ENTIRE thyroid. My dr lowered my dosage. Does the body make more T3/4 elsewhere?

Adjust the dose: You do need levothyroxine after removal of thyroid gland. Usually if the lab test shows very low TSH then we do need to decrease the dose so that TSH comes up to acceptable level. Sometimes patients need less dose with advancing age or after losing weight. T4 is solely a product of the thyroid gland, whereas T3 is a product of the thyroid and other tissues where it is formed by deiodination of T4 ...Read more

What is the typical dosage for a new patient with hypothyroidism going on Synthroid or levothyroxine?

What is the typical dosage for a new patient with hypothyroidism going on Synthroid or levothyroxine?

Depends: Since you were just diagnosed, you should work closely with your doctor to find the proper dose of levothyroxine. The dose is based on the level of your thyroid function tests. And it is calculated based on your weight. So the range of the dosage is listed as from 50 mcg to 200mcg a day. So you see that it is not possible to answer your question as precisely as you may wish. Please ask your doctor ...Read more

May be: It would be prudent to consult your doctor who is prescribing the medication, before reducing the dose. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more
