I took only lasted 10 days on Tirosint. My issue was with muscle pain/cramps, so severe in my upper back that it was hard to breathe. I had them in my calves, neck, shoulders, upper back and then hands and fingers making it quite difficult to work daily, so I gave up. I am not sure why it did not agree with me, but the day after I stopped, it went away. I too wish it would have worked for me :(
Did you lower to the next dosage or were you on the same mcg as your previous med?
Look at some of my posts. Went through everything you are speaking of. Some of my posts have been locked but you can still read. Made it 6 weeks and had to stop.
I totally agree with Laura, that Tirosint is about as hypoallergenic as you can get. There are no common side effects; most side effects are the result of over or under medication.
Being a gelcap, with no fillers, absorption is greater than with a pill. It's always best to start a new med on a lower dose and let your body adjust to it, before trying to get to the full therapeutic dosage.
I actually *increased* my dosage when I went on Tirosint; went from 88 mcg levo to 100 mcg Tirosint and it's done awesomely for me.
I actually changed from 100 of Synthroid to 100 of Tirosint along with no change in my cytomel. I could have been under or overdosed, but felt horrible and had a not so great endo, so I knew they might give me trouble. I may have given up too soon..but it was not fun at all. I also gained 5 lbs in 10 days on it....once I switched back to Synthroid, I have lost the weight and my muscles are fine now. I am not sure what happened, but I decided to switch back. Good luck with whatever you decide!
I switched over at the same dosage...and have increased since. I had room to work with though....my t4 level was only in the low normal range. But....I am also on Cytomel (T3) as well. I feel great on Tirosint.
My next question to you is what was your last Free T3 level?
You can have too much T4 and too little T3 in your system which will cause hypo and hyper symptoms both! It happened to me....I was a train wreck until i added the T3.
