Nerve and muscular symptoms on medication increase

Hi everyone,

I was wondering whether any of you had ever had any nerve or muscular symptoms following a medication increase? Whenever I increase my levothyroxine I often get weakness in various muscles and this is most noticeable in my hands. I have tried a smaller increase this time, with just 12.5mcg, but I am still having problems.

Currently my thumbs feel a little weak and achy and my left thumb muscle is twitching a lot and is a little shaky. It feels like I have electricity running through my hand sometimes too.

If anyone has any experience of this please comment. Thanks.

Foxrabbit,

Do the symptoms improve once you're used to the dose increase?

It took 10 weeks last time before the symptoms passed but I have new ones this time as I haven't had the twitching thumb muscles before

Do you take supplements? If yes, what do you take and at what dose?

Yes I do. My B12 is above range and folate halfway through the range so I take Jarrows B-right once a day to keep them that way, it has around 100ug B12 and 400ug folate. I still take the high strength versions I have of them once a fortnight too. Vitamin D was above highway through the range so I take 2000IU every other day with K2. My ferritin was low so I take a spatone sachet every morning and I've added in a solgar 25ug iron capsule in the afternoon.

For muscle spasm, cramp, twitching, and benign fasciculations, the things I've found helpful are :

1) Ferritin (iron stores) and other iron-related measures - raising to optimal.

2) Vitamin B12 needs to be optimised, but this doesn't seem to be an issue for you. Although you could have high B12 and still have a functional deficiency of vitamin B12.

3) Potassium - supplementing Vitamin B12 lowers potassium levels which causes painful spasms and cramps. I'm sure there must be other causes of low potassium. Lists of potassium-rich foods can be found on the web. I actually take supplements because I'm lazy. I take a maximum of about 400mg potassium per day, but usually take half that.

4) Magnesium supplements - these are very helpful for cramp and spasm. They come in various forms - choose one that appeals to you.

5) Always do your own research - I'm not medically trained, so nothing I say should be taken as gospel truth without checking first.

Many thanks humanbean, some really great suggestions there. In my desperate internet searches yesterday I also came across low potassium and it rang alarm bells as my last blood test showed low serum potassium levels a month ago so I ate a few bananas to raise it and then forgot about it but maybe I need to think about supplements! The last few nights I've had a bath with Epsom salts or used my magnesium spray to see if that helped too, so hopefully I'm working on everything I can to help ease it! Thanks again for the great advice

Sorry humanbean , this was supposed to be a reply to your message but I hit the wrong thing!

I've seen your reply now. :D

Most people are not impressed when they read that I take potassium supplements and think I should include potassium-rich foods in my diet rather than supplement.

You know what? I think they are right. But I'm still too lazy and I still supplement potassium - very cautiously. ;)
