L-Thyroxine and Blood Pressure

[Dragon7]

Hello,

My Dr. prescribed L-thyroxine 150 mcg/day in response to a 30lb weight gain in the past year (fat) and the following blood test:

T4, Free 1.4 range 0.8-1.8

TSH, 3rd Generation 3.46 range 0.40-4.50

I read on paperwork with the prescription that L-thyroxine should not be taken with decongestants, but it doesn't specifically say that L-thyroxine raises blood pressure, but I'm kind of drawing that conclusion, but wanted to clear....

Can L-thyroxine raise blood pressure?

Thanks

From your bloodwork, I can't figure why your Dr prescribed some T4 (L-Thyroxine) to you... there must some other reasons to your weight gain than abnormal thyroid levels.

your problem is probably T3 related not T4

stimulants and thyroid medicine, it may amplify, but i do it anways, but i dont recommend.

Thanks for the responses. I don't know the difference between T3 and T4 so I will have to do some reading.

Have you had any post medication bloodwork done? Judging by your T4 levels before you started meds, they're probably insanely high right now. Your doctor did not test your T3 levels which have more of an impact on your metabolism.

And yes, high blood pressure is a side effect of having your thyroid levels too high.

I will be getting back my first results on the medication in about one week.

My test has a T3, free of 342 (he didn't mention this number at all, only the T4 and TSH.

So what you are saying is that the L-thyroxine will raise the T4 even more?

thyroxine is T4

take more T4 your blood work will have higher T4,,,and lower TSH

when i was hypo i had HUGE bp,,,thanks to cortisol going out of control with low thyroid

many issues here,,i think you need a better doctor....find an endo not your primary

how do you feel on t4? better? or the same

Thanks for the responses and I apoligize for my ignorance on the subject, I should have done more research and reading before jumping into questions. It's all still new to me. I will read the stopthethyroidmadness - thank you.

I don't feel much difference until I start working out, then I'm sweating a lot, a ridiculous amount.
