Synthyroid overmedication makes me crazy

Hi Sania, what you’re experiencing is typical. When you change doses, you’ll often get spikes (less likely valleys) in results while the meds re-equilibrate. Three weeks isn’t long enough- it takes a full three months for the meds to level out.

Aside from that, my experience has been that the meds mess with the thyroid feedback loop to the point that it’s nearly impossible to get the dose right. Other people on this site have been able to get a stable dose. I was never able to get it stabilized.

You might try working with a (very experienced) endocrinologist to see if you can get help getting the dosage right.

Good luck!

Hi, Sania, i agree with MtViewCatherine, changing doses takes ages, levo is a long acting medication.  But why would your doctor reduce so little when you are having such symptoms and when your tsh is far too low? it looks like you have either been having far too much levo and it has built up, or maybe things have changed a bit in your body - there may have been hormonal changes in the last months? Something else?  Or may be nothing you can explain. i myself find levo, even small amounts, builds up too much and sometimes have to have a few days  off now and then if i have symptoms - maybe you need to discuss everything with your doc., as everyone is very different and levo is not a medication to alter without advice, as too little can have side effects, and too much can be dangerous for the heart and the bones.

You sound as though you are very sensitive to Levothyroxin, in which case it's better to be lower than higher when it comes to how much you take. I'm only able to take small amounts of it now as I'm intolerant to it I found that out a couple of years ago.Finding an Endocrinologist who understands and accepts side effects isn't easy, as I've found out. I'm going to see my third Endocrinologist soon I hope. This time I rang the Endocrinology Dept myself and asked if they understood what I was saying, they assured me that they do and have someone who can help, hoping for third time lucky. Good luck and I hope you find someone to help you.

Sami, one more thing to consider. I’ve found artificial sweeteners such as aspertame to influence thyroid levels. 

I noticed with the meds I stopped drinking diet soda because I didn’t need the caffeine. But the diet soda contains a form of phenylalanine, which is a precursor of thyroxin.  While I font advocate for diet soda  or artificial sweeteners, I’ve given up trying to cut out the diet soda, as I actually feel better when I drink it.  How nuts is that!
