Doesn't matter: Thyroid hormone levels do not rise and fall after each dose because of its long half life in the blood so it does not matter when you take it and it will not interact with your BC. Also, 25 mcg is a very small dose for an adult and if your thyroid tests are fine on that dose, there is a good chance you could do fine without it. ...Read more

Dx hypothyroid in April, been on synthroid (thyroxine) 0.025mg x 3 months, but TSH went higher (~13) w/ normal ft4. Could viorele birth control cause high TSH?

What's the next dose: Don't think so. More likely it is because 0.025mg is the smallest Synthroid (thyroxine) pill. Synthroid (thyroxine) comes in about 12 sizes, from 0.025mg to 0.300mg. If one's doctor started her on 0.025mg and there is no drop in the TSH, one can ask at her follow-up visit (there is always a lot of follow-up until the proper dose is found and the TSH is normal) what the next dose is. ...Read more
