Levothyroxine in pregnancy
Common Questions and Answers about Levothyroxine in pregnancy
synthroid
Levothyroxine, also called L-thyroxine, is a synthetic form of thyroxine (thyroid hormone). In the United States, brand names include Synthroid, Levoxyl, Levothroid, Eltroxin, Tirosint and Unithroid; Generic forms are Levothyroxine sodium USP and L-thyroxine. There is still debate over whether generic thyroid supplements are as effective as thyroid brand name supplements.
I had the same question and concern for an endocrinologist on Thurs., 2/26, and she said two things on this subject. 1) There is only one study about IQ and mother's TSH during pregnancy, and the study has been largely discredited due to have small sample and the way it was executed; 2) TSH level has most effect on baby in later pregnancy (believe third trimester). In my case, she's having my TSH checked every four weeks during pregnancy.
Those were the same symptoms I had early on and I'm pregnant
My hypothyroidism was identified right before my pregnancy - and it got REALLY bad during that pregnancy. In my case, it was difficult to diagnose because I had a normal TSH, but a low Free T4. Finally, in the past two years, I have begun to lose weight - I am down to 175 from 225, but it HAS been a struggle. However, I did not GAIN more weight after starting on Synthroid (except during my pregnancy, of course).
Levothyroxine takes approximately 6 weeks to reach full potential in the blood. While your TSH is over range, it's the FT3 and FT4 levels that are the most important, since TSH is a pituitary hormone and can vary for a multitude of reasons, even intraday.
When you get the results for the FT3 and FT4, please post them here, along with the reference ranges, which vary lab to lab and must come from your own report.
Wondering if anyone else has experienced allergic reaction or sensitivities to 134 mcg (blue) Synthroid, and if anyone has switched to Compounded Levothyroxine with Avicel as the filler and had a reaction to that filler. Also wondering if Compounded Levothyroxine would be as effective in managing hypothyroid symptoms as Synthroid, as after my total thyroidectomy in 2006 they started me on generic levothyroxine and it did not help, but the brand name Synthroid did help to improve my TSH levels.
I understand exactly why it's a big deal for you when you're trying to conceive, however, it's not the levothyroxine that's causing your period to be late; it's being hypothyroid.
12.5 mcg of levothyroxine is a very small dose - basically a starter dose. Did your doctor indicate whether s/he might be planning to increase your dosage, after a certain amount of time?
I was diagnosed in 2013, my current dose of levothyroxine is 50mcg and the reason it is this low a dose is because of the acacia in the Teva levothyroxine I have been prescribed. I am also planning to be pregnant.
Any advice about how to proceed next would be welcome, thank you.

TSH 2.65 (0.2 - 4.2)
FREE T4 15.1 (12 - 22)
FREE T3 3.2 (3.1 - 6.
Overtreatment with levothyroxine sodium may have adverse cardiovascular effects such as an increase in heart rate, cardiac wall thickness, and cardiac contractility and may precipitate angina or arrhythmias.
I found this and I think maybe is necessery to reduce the dose. And I think you should consult your endocrinologist sooner than 14 may. Good luck.
This may increase the risk of miscarriage and other pregnancy problems, including developmental delay in the child. Immediate intitiation of thyroid hormone (levothyroxine) is necessary at a full replacement dose (usually 2mcg/pound, sometimes more for pregnancy) and recheck levels to confirm it is not a lab error. Would discuss with your OBGYN and consider endocrine consult as well. Sometimes we send women to "high-risk" OB for more thorough evaluation in these cases.
My OB perscribed 137mcg levothyroxine with another test in 6 weeks. I have a formal appt with her later this week. In themean time, a family friend suggested a chiropractor. I have never seen a chiropractor, so I was a little sceptical. He found some weird tender places in my neck and did a few adjustments that took all of 30 seconds. I walked out of there feeling better than I have in MONTHS! For the first time in a long time I had enough energy to give my 1.
She rechecked his blood and discovered Hashimoto and changed the meds to levothyroxine 0.88mcg. He was feeling ok with the synthroid and now after 4 days of the levothyroxine he feels extremely exhausted and feels as if he is hallucinating (sp) during the day on several occasions. Bad dreams too. Any suggestions. He cannot even go to school today he is so tired.
Doctor,
I am hypothyroid, taking 25mcg of levothyroxine. I am now 6 weeks pregnant and wondering at what week I should have my doctor test my dosage. I understand that it is highly likely that my dosage level will need to be increased. I have also read that the majority of pregnant women see a change in TSH levels at about 8 weeks, but that it takes 4-6 weeks for the dose to "kick in." During this time, will it hurt the brain development of the baby?
The pregnancy should not be effected by thyroid surgery and levothyroxine replacement which would follow thyroid gland removal. Would need to make sure levels are appropriate before trying to conceive. This is a common scenario. The main question is indication for thyroid surgery -- ie, suspicious biopsy, compressive symptoms, thyroid nodule over-activity....would make sure there is a clear indication before removing the thyroid.
you must mean hypOthyroidism -- key with pregnancy is to adjust the levothyroxine (preferably a brand to ensure consistency in pregnancy) to keep TSH in the 0.3-2.0 range before and during pregnancy.
Concerning thyroid hormone replacement there are mainly two types, levothyroxine and natural dessicated (NDT) one and also another like T3 only with mixing with levothyroxine etc. Levothyroxine is choose by most doctors but I think everyone should go on a trail on natural dessicated ones too at least for some 1 month and choose the one which gives them better feeling.

hello. is it safe to take methylsulphonylmethane supplements and levothyroxine? do you guys ever heard of any interaction between those?
Im taking cranberry pills aswell i would like to hear from you if cranberry interact with levo, or theres no need to be worried here....
In 2005 I had my thyroid removed due to cancer (also took radioactive iodine). I am currently taking Levothyroxine and am 5.5 weeks pregnant. I had my TSH tested yesterday and my level was 0.34 and I am concerned because with my first pregnancy I had to increase my dose right away. But, according to my levels this time my dose can stay the same. Should I be worried that my TSH hasn't started creeping up, requiring more thryoid hormone replacement?
Oroxine (original) and Eutroxsig (generic). They are both packed the same. There are 200 tablets in each box. The doses are, 200mcg, 100mcg, 75mcg (a recently introduced dose which the ATF lobbied), and 50mcg. They are packed in blister strips, plastic and foil. Because of the climate in Australia, the tablets must be kept in the refrigerator and are stored in the refrigerator at the pharmacist.
