I'm allergic to iodine. I am hashi hypothyroid. Can only take brand Synthroid (thyroxine) & cytomel. But when taken together I have a severe allergic reaction.

I'm allergic to iodine. I am hashi hypothyroid. Can only take brand Synthroid (thyroxine) & cytomel. But when taken together I have a severe allergic reaction.

Check w/Pharmacist: If you mean taking the two pills at the same time causes a reaction, but taking either one by itself does not, then you could try taking them several hours apart (like one w/bkfst and other w/dinner). If that fails, will need to talk to endocrinologist to see if can manage on one agent. ...Read more

Is cytomel safe to take? I don't feel Synthroid (thyroxine) is enough because i still feel bad

Is cytomel safe to take? I don't feel Synthroid (thyroxine) is enough because i still feel bad

Go to your doctor: Cytomel (liothyronine) is mainly for supplementation of your t3, which is way more potent than your T4 and is the end product of your t4. Be careful in taking medicines that your doctor has not prescribed as if you cause hyperthyroidism, your heart status can also suffer. It is best to have your level checked and medicine adjusted. ...Read more

I have hashimotos. On Synthroid/Cytomel. Dr says Levels are normal. Lymphatic massages 1X a week.  Still having a lot of symptoms.  Frustrated!

Hashimoto's: Hashimoto's disease often leads to hypothyroidism (underactive thyroid). Check out http://www.mayoclinic.org/diseases-conditions/hashimotos-disease/basics/definition/con-20030293 & http://www.mayoclinic.org/diseases-conditions/hypothyroidism/basics/definition/con-20021179. Unfortunately, symptoms can be vague & nonspecific. Worse, there's wide range of normal. Ask for higher dose then recheck TSH. ...Read more

Can metformin interfere with the absorbtion of thyroxine and cytomel (liothyronine)?

Can metformin interfere with the absorbtion of thyroxine and cytomel (liothyronine)?

Not reported: Metformin has not been reported to interfere with the absorption of thyroid hormones. One report suggested it could lower TSH levels in some patients but with no effect on thyroid hormone levels (t4). I recommend you have your levels checked if symptomatic or as recommended by your provider. ...Read more

Does taking cytomel or Synthroid (thyroxine) to help lose weight?

Does taking cytomel or Synthroid (thyroxine) to help lose weight?

Thyroid weight loss: Thyroid hormones should never be used for weight loss. They may increase your metabolic rate, but will also increase appetite. And there is a large potential for side effects. Beside making, you feel nervous, jittery, sweaty, they accelerate your heart to the point of serious problems and can cause mental health problems. ...Read more

4-21-14 Thyroidectomy r/t thyroiditis, goiter. On Synthroid (thyroxine) 137 mcg- hypo s/s returning have felt great for months. Would adding Cytomel help?

Not specific: The signs & symptoms of hypothyroidism are not specific for hypothyroidism (not a single one). Recheck your thyroid labs. If they're normal, your symptoms are due to something else. Having said that, I'm happy to do a trial of Cytomel with the Synthroid (thyroxine) in patients who want to try as long as I don't make them hyperthyroid. Some people report feeling better with comparable labs taking a little T3. ...Read more

Can taking too much Synthroid (thyroxine) plus cytomel, therefore having a very low TSH level, cause seizures?

Possible: Both high and low thyroid states can be associated with seizures. Seizures can be seen in 5-10% of high thyroid states and even more commonly when it is due to an overdose with medication. If you are experiencing this, go to the nearest er as this condition is life-threatening and needs immediate attention. Your doctors will also search for other conditions that may be causing seizures. ...Read more

Tsh 0.01, free t4, 1.34, tpo 113. On 25 synthroid, (thyroxine) 5 cytomel. Doc not happy with tsh. Isn't TSH suppressed when taking t3? Hashimoto's by biopsy.

Depends: Your TSH is suppressed. Consider finding a good integrative medicine doctor or a nd to help with the autoimmune process. They can suggest things to actually bring down the tpo level and help your body heal. For your best long term outcome, more needs to be done than just thyroid meds. ...Read more

I take cytomel(t3) 10mg daily with synthroid 50mg daily for a thyroidectomy in 2010. Does T3 (liothyronine) cause an increase in creatinine? Microabumin/creat is 59h

No: Cytomel (liothyronine) is a synthetic form of triiodothyronine which is one of the hormones normally made in the thyroid. There is no evidence that it should affect renal function; this abnormality should be evaluated separately from your hypothyroidism. ...Read more

43 yo healthy F, thyroidectomy 2012, on Synthroid (thyroxine) & Cytomel with continued hypothyroid symptoms. Would like to try Naturethroid. Will dr consider rx?

Of course: B"sd Naturethyroid and Armour thyroid are made of dessicated livestock thyroid — I believe manufactured at the same facility. Accordingly, they contain the mix of thryoid hormones found in barns and pastures and have a bit more T3 — cytomel, (liothyronine) relative to T4-synthroid. Much more convenient than split does replacement, but on the other hand allow for less flexible dosing plan s. Glad to discuss ...Read more

What's the best medicine to treat hypothyroidism during pregnancy? I'm on Synthroid (thyroxine) should I take cytomel too?

No need.: Cytomel is useful when either a rapid rise, or a rapid fall, in thyroid hormone levels is needed. If there is need to adjust dosage in pregnancy, slower acting synthroid (thyroxine) works just fine. ...Read more

Can hypothyroid symptoms be fast heart rate and insomnia? Will adding cytomel to Synthroid (thyroxine) help?

Maybe hyperthyroid: Hyperthyroidism (too much circulating thyroid hormone) will often produce rapid heart rate and insomnia — along with other symptoms like diarrhea, weight loss, and jitteriness. Low thyroid may cause weight gain, sluggishness, coarse/dry skin, and constipation. Ask your care provider about your symptoms. Please do not "freelance" with Cytomel or synthroid, (thyroxine) as this may harm you! Lgromko md. ...Read more

Stop Cytomel (liothyronine): Thyroid blood tests can't check levels of Cytomel (liothyronine) appropriately, it can only confuse the results of the blood tests. Cytomel (liothyronine) is not helpful and potentially harmful and most endocrinologists would not recommend it for replacement therapy. ...Read more

Any info on thyrolar (thyroxine and liothyronine)?

Thyrolar (thyroxine and liothyronine) info: Thyrolar (thyroxine and liothyronine) is a trade name for a t4/t3 combination form of thyroid hormone. While T4 gives a smooth onset of action which can take several weeks to stabilize, the T3 component gives a rapid and unnecessarily brief rise in T3 levels. This discordant effect can cause side effects and make thyroid blood tests difficult to interpret. There is no proven benefit to using this type of thyroid hormone. ...Read more
