Taking 500 mcg levothyroxine. When I reduce dose the symptoms return rapidly. Isn't 500 to high?

Hypothryroid: Treatment is based on laboratory confirmation of the dose of medication the patient is prescribed. Therefore, if your TSH is in the correct range on 500 mcg and your symptoms are controlled then you are on the correct dose. Read more

I take 100 mcg levothyroxine once a day and I think I accidentally took another dose should I be worried will this hurt me please advise?

I take 100 mcg levothyroxine once a day and I think I accidentally took another dose should I be worried will this hurt me please advise?

Don't worry: You'll be fine. Levothyroxine is slow in onset and long lasting. In fact, for occasional people with compliance issues, we will give one week's worth of levothyroxine all at once (eg. 700 mg once per week). It is possible you may feel a "buzz" today (palpitations, tremor) but probably not, unless it is from anxiety over it. You can skip tomorrow's dose. Read more

I'm on 75 mcg of levothyroxine T4 can I take 75 mcg of triiodothyronine t4?

Depends: Depends on what your body is doing to the T4 and how you are feeling. If you still have symptoms of hypothyroidism, it may be worth looking into. More info on http://drfairchild. Blogspot. Com/2012/12/proper-thyroid-testing. Html Read more

My wife is fainting every few months. She takes Levothyroxine 100 mcg and Prevacid (lansoprazole) 15 mg. We are concerned.?

My wife is fainting every few months. She takes Levothyroxine 100 mcg and Prevacid (lansoprazole) 15 mg. We are concerned.?

Very much so: B"sd I would be terribly concerned. Little reason to blame the meds. She needs cardiovascular and perhaps neurologic evaluations. On the serious side, brings to mind heart problems, abnormal blood pressure regulation or seizures Read more

I've been on 100 mcg levothyroxine for 12 years and I want to stop cold turkey. Will I lapse into a coma? What's the worst that can happen and when?

I've been on 100 mcg levothyroxine for 12 years and I want to stop cold turkey. Will I lapse into a coma? What's the worst that can happen and when?

Why: If you really have a poorly functioning thyroid gland, the med just provides something your body cannot make. If stopped, you would gradually become hypothyroid, slowing of your metabolism, weight gain, changes in heart rate, temperature sensitivity, stooling pattern, etc would be gradual. You would realize you need the med in time to reverse the change. Read more

I accidentally took 2 88 mcg levothyroxine pills, and I do not have hypothyroidism. Will I be okay?

I accidentally took 2 88 mcg levothyroxine pills, and I do not have hypothyroidism. Will I be okay?

YES YOU SHOULD BE: Just watch for rapid heart beat but it will be out of your system within next 24 to 72 hours. There will be no long term effects as well but check in with your doctor as we don't know if you have any other medical condition. Like heart disease, hypertension etc. Read more

I was born without a thyroid how long can I live without medication I take 200 mcg of levothyroxine?

I was born without a thyroid how long can I live without medication I take 200 mcg of levothyroxine?

Quite a while: Without any thryoid hormone around you could live quite a while but you would become very uncomfortable. You would get fatigue, mental slowing, weight gain and constipation. Later more serious life threatening conditions could occur. I would seriously suggest that you not stop the thyroid replacement medication and see your healthcare provider regularly to make sure the dose is correct. Read more

Currently on levothyroxine and my numbers are 1.600 and take 175 mcg. I weigh 318 lbs and feel cold and tired all the time and no energy?

Currently on levothyroxine and my numbers are 1.600 and take 175 mcg. I weigh 318 lbs and feel cold and tired all the time and no energy?

Thyroid and symptoms: What number is 1.6? Is this the TSH? That is normal. 175 mcg is a good dose. Although you feel cold and tired, these symptoms are likely not due to hypothyroidism. Talk to your doctor about what else may be causing your symptoms. Read more

Levothyroxine: The needs of thyroid hormone for your body can change with age. If you are taking thyroid hormone and you need less, taking more causes labs to show hyperthyroidism. So it is called iatrogenic hyperthyroidism, which is caused by the consumption of thyroid medications. Seeing your doctor would help to decide if you need less thyroid hormone. Read more

I'm 16 and have been taking levothyroxine 25 mcg for 8 years. I am always tired and I exercise constantly, but I'm still gaining weight. What can I do?

I'm 16 and have been taking levothyroxine 25 mcg for 8 years. I am always tired and I exercise constantly, but I'm still gaining weight. What can I do?

Watch diet: See your doctor to develop a diet and exercise plan that is best for you. Be honest about your concerns. There is a small chance your dosage may be adjusted. The most likely problem is diet. Reduce carbs, eat small meals more frequently, favor slow burn carbs over quickly absorbed carbs like sugars and starches. Cut out soda pop. Switch to water. Keep a log of all you eat and calculate the calories. Read more

How high a dose is 75 mcg of levothyroxine? How often should blood be checked for hypothyroidism?

How high a dose is 75 mcg of levothyroxine? How often should blood be checked for hypothyroidism?

Modest dose: That is a modest dose for an adult with hypothyroidism. Doses vary from patient to patient, and thus so does the need to check dose. A minimum would be once a year, but when initiating treatment, if weight changes significantly, if adding other medications, etc - all these things could alter your needed dose. Best to confer with your doctor/endocrinologist to find the perfect dose for you. Read more

Since being on lithium my TSH has gone from 1.5 to 8.4. What does that mean? I already take 25 mcg of levothyroxine.

Since being on lithium my TSH has gone from 1.5 to 8.4. What does that mean? I already take 25 mcg of levothyroxine.

Lithium: Your elevation of TSH means that your thyroid gland is under-functioning, or hypothyroid. This is a known side effect of lithium. Please talk with your endocrinologist and psychiatrist about this -- it is severe enough that at the very least, you'll need to adjust your thyroid medication if not possibly change to a different mood stabilizer.

I'm taking levothyroxine sodium 125 mcg per day, what supplement can I take to lose weight? I eat healty & exer. I weight 194.Im 47yr. Old,

No easy answer: As long as your thyroid level is normal, this is not the reason for your weight problem. Although supplements are a multi-billion dollar industry, there are very few if any legitimate studies that show that they work. You should get a full examination to make sure there are no other reasons for your weight problem, after that it comes down to the basic reality of fewer calories in, more exercise. Read more
