Is this normal ? How long do they take to leave your system if you stop taking them ? Thanks

    I've been fortunate to have no side effects. My doctor took me off mine once and said it would take about 2-3 weeks to get out of my system. I too am on 50mcg. I am sure the meds can cause several side effects but so can your thyroid. I would talk to your doctor before coming off as if you have a thyroid disorder, it can cause several problems for you. Let them know of your side effects and see what they advise. Hope you feel better soon.

    Hello Hlxxxx, it took months for the levo to fully get out of my system, but I was on 200mcg for nearly three years. I felt as if the bulk of it was out after three months. This was the worst if it, as I could smell the chemical detox as it came out. After 6 months, much better, now it's a year and I'm still improving. I can totally understand the horrible side effects. I had extremely bad side effects and the medication didn't work for me at any dose. Synthroid was the worst as far as side effects, as it contains additives that trigger the immune system. I tried compounded for several years, But it never really worked and my thyroid disease worsened dramatically, as shown by a massive increase in thyroid cysts. With the compounded, the side effects were less, but really, it didn't work at any dose.  My feeling is that if it doesn't work initially, it won't improve enough to be effective.

    You might try NDT, Armour, if your thyroid disease is mild. Also, OTC ThyroGold is excellent, and is the closest biologically to human thyroxins. American Biologics makes a fairly good product as well. Just some things to try.

    None of the thyroid meds are truly bio identical, so you'll have a tough time with the thyroid meds no matter what.

    Also, since you're on a low dose, you may be able to reverse the thyroid disease with diet and nutrition. Time consuming but worthwhile.

    Do read through the many posts here, especially, "unacceptable side effects of levothyroxin", as you'll find that others have had similar experiences, and are supportive and offer many excellent bits of advice.

    Hope that's helpful.

    I was on levo for approx 7mths and stopped due to so many side effects. My dr I've just seen today (5mths after stopping levo) and she says that the meds may be out of my system by now but my body still need a few more months to adjust.

    I'd think that the meds would be out of your system but it's also important to help your body function. If you are borderline hypo there are so many supplements that you can take to help boost your thyroid system. I'm currently on Actyr and find it's a huge help.
