I just got blood work done at my first prenatal appt and my TSH level was at 16 so I was immediately prescribed 75 mcg of Synthroid.  My question is.... is that dose high enough? I’m 9 weeks pregnant and weigh about 130 lbs .  I have a friend that’s a dr and she seems to think that’s a tad low.  Any input would be greatly appreciated.  I just want to do the safe/right thing for my baby.  Thank you!

    Hi Lauren, normally thyroud medication is increased slowly because it can really throw things out of whack. 

    75 is a very high start dose and if will take a while for your body to adjust. 

    Most likely, your doc is considering your pregnancy, where hypothyroidism is known to result in miscarriage. They’re likely walking the fine line between prescribing a high enough dose to prevent miscarriage, while not traumatizing your system with too high a dose.

    You will need 50% more of levo as your pregnancy advances or your baby (and you) can be affected at birth and throughout life. Don't be afraid of the med YOU AND YOUR UNBORN BABY REALLY NEED IT THROUGHOUT your pregnancy. 75mcg is not that high that is just a starting dose. What were your other thyroid test results? Make sure you get your thyroid testing done as often as possible. Pregnancy puts a great strain on your thyroid. Dont take any BIOTIN or B7 2 days before testing. Biotin is used by labs for thyroid function tests and MANY OTHER TESTS. BIOTIN can give false results: suppress TSH and falsely increase T4 T3 etc. and confuse everyone.

    Hi Lauren my advice would be to start on 25mg and gradually go up to 75mg , normally when pregnant your level in medication can double . And the slowly reduced after the birth ...

      No, she shouldn’t start on a low dose when pregnant. Especially if she’s newly diagnosed with a tsh that high. She’s already nearly three months so she needs to get her tsh down from 16 to  as near to 2 as soon as possible. Especially when it will probably be another 4-6 weeks before another possible increase

    Starting too slow may deprive the unborn baby of necessary thyroid hormones for overall growth. It's already 2 months plus. Your thyroid gland and body are being overworked even without a thyroid disorder.

    It is a bit low but your doctor may be starting out low and working up to the dose you need. Make sure you get your blood drawn as your doctor tells you.  You will probably get your dosage changed a few times until your tsh level is correct.
