Accidentally Took Double Dose of Armour for Three Days

I knows its been quite a while since I last posted. Over the past months, I have been struggling to switch over to Armour from my levothyroxine and find a dose where I would be stable enough to call it the beginning of success. Beleive me it has been quite a difficult journey.

A few weeks ago, I was up to 60 mg (1 grain), and barely made it through the second week waiting to up my dose another 1/4 grain. Each time I consider I feel better when I up the dose, by the middle of the second week, I am suffering severe symptoms (esp a return to my old psychological symtoms) and can hardly survive till the next increase.

Nearly two weeks ago, I went up to 75mg (1 and 1/4 grain), and seem to have stabilized and seem to have achieved a more consistent reduction of symptoms.

Anyway, I had a new prescription filled a few days ago, and did not notice that they were the 30 mg (1/2 grain) pills. So, I was taking 5 of them, thinking they were each 1/4 grain. I did this for 3 days, in effect taking 150 mg (2 1/2 grains). I was thinking to myself during this time, "wow", I guess I will n ot need another increase as yet, since I feel so good...though as time wore on, I did feel a little bit hyper and started having fluttering in my chest.

Well, when I noticed yesterday what had happened, I decided to take 45 mg, (3/4 grain) or a half of my normal dose. Yesterday was not pleasant, and I realized I probably should have taken less.

I am wondering what I should do to even out my blood levels? Should I take nothing for a few days? Or instead take a smaller portion of my normal 1 and 1/4 grain dose? I feel terrible today, sleepy, lethargic etc., and a bit anxious (overstimulation anxious).

Finally, has this happened to anyone else?

Re: Accidentally Took Double Dose of Armour for Three Days

While thyroxine has a half life in the body of about 7 days, triiodothyronine (T3) has a half-life of about 10 hours. I would skip a day and take a smaller dose.
I also switched from Levothyroxine to Armour and I also have a hard time with it. I started on 30 mg for 2 weeks and now upped to 60 mg.
I still have hypo symptoms but like Midwest always mentions, you can't rush it.
Take your time and increase your Armour slowly.

Good luck

Re: Accidentally Took Double Dose of Armour for Three Days

When I started the Armour in May, I was on 88 mcg thyroxine and 15 mg Armour. My Dr increased me to 75 mg thyroxine and 30 mg armour. Then I switched to 45 mg Armour alone. Shortly afterward, I had a bad experience, where I ended up so dizzy I was falling over and nearly fainting, and had weird "buzzing" in my brain, I felt like I was having some mini seizure. Well, I went to the ER and ended up discontinuing everything. I think I had too much T4 still in my system, plus I had never responded too well to the T4.

After a week of no thyroid hormone at all, I tried 15 mg Armour, but it was too much - palpitations, and "flip flops of my heart. Eventually, I was able to tolerate the 15 after a period at half of the 1/4 grain pills (7.5), but by that time, I was sooooo slow, my body moved like it was in slow motion, my mind could hardly receive any information - it was like I was a zombie. So, I went back on a half dose of the thyroxine (44 mg) and 15 mg armour, and felt better.

Since that period in July, I have beein slowly increasing the armour and decreasing the thyroxine. In the beginning of September, I was at 45 mg Armour and cut the thyroxine altogether.

The past six weeks have been a hard time for me. As I described in my post, I could hardly live until the next increase. A lot of my psych symptoms returned. and by this time, I had long ago cut back to virtually nothing on my anti depressant and anti anxiety medications. I was nearly tempted to increase these two, but could not face having to go through the withdrawal again of titrating down.

Luckily, I lived through it and found consistent relief at 75 mg armour. THANK GOD I know I have a way to go - especially from the good feelings and great energy I had initially with accidental higher dose, until I started to feel too stimulated.

I have found that the 15 mg every two weeks worked for me, which I understand is the protocol given by the company that makes Armour.

Good luck with your Armour experience

All I know is that I feel I am rounding the corner (aside from this little snafu). Armour has been a million times better than the thyroxine. My fatigue abated some time ago, and I seem to have more stamina and DEFINATELY a quicker recovery time from exercise etc. This is something that NEVER happened with the thyroxine even at higher doses than 88 mcg. T4 treatment did give me a little energy, but more of a overstimulated feeling. It also helped with the anxiety and depression - but the one, and most important thing T4 treatment never provided for me was that elusive sense of well-being. I am so happy that I have gotten back what I have not experienced in many, many years, maybe since I was a teen. At the dose I am at, I have more moments than not with a sense of well-being. I look forward to have it 24/7 when the Armour dose is optimum. Hopefully soon!

Re: Accidentally Took Double Dose of Armour for Three Days

I know how you feel. I have taken Synthroid but didn't feel great.
My Ft4 was always on top of its range and my FT3 below middle range.
I found a doctor who was willing to switch me to Armour. I worked my way up to 60 mg until I had to move out of state.
I went to a holistic MD who wasn't willing to give me my Armour instead he switched me to levothyroxine. I started to get terrible joint pains and I couldn't sleep anymore at night. I went to see another DO and he was willing to switch me back to Armour.
Like you I had to start on a very low dose all over again and I agree it is best to add 1/4 grain each raise.
I have been to 5 different doctors already I never thought it can be so difficult to get proper treatment. Asking for Armour feels like you are asking for a heavy painkiller, unbelievable !!
Good luck with your Armour
