levothyroxine users - a question

[ElizK]

I was told to post this on this board, so here's the orig post from the Community Board:

Ever had an allergic reaction to Levothyroxine? I've been having rash/hives randomly show up, mostly on my arms. This has been going on for MONTHS, maybe as long as a year. I usually slather some Benadryl gel on the offending area and go along with my life. It was really bothering me today, so I started checking around and discovered it could well be my thyroid medication! It could just be stress, too, but how do I figure out which one???

I'll call my doctor tomorrow, but I'm just wondering if anyone else has had this problem, and what medication you were switched to, and what the cost difference was. I just had a 3 month supply filled at the pharmacy! Oh, well. I'm ready for this to STOP!!!

When I first started on levothyroxine, I broke out in hives every time I went in the sun. I got a rash on my face that made doctors think I had lupus. But my doc decided that it was probably a reaction to the colorant in that particular brand and dosage, so she switched me to another brand and dose.

I eventually developed severe adult asthma that had me on a nebulizer and virtually diabled. As a result of the steroids for the asthma, I also developed osteoporosis. I was only 40!

Eventually, after 3 years of suffering from the asthma, pain, rashes and fatigue, my doctor was about to give up on me because none of the specialists that I saw could determine the cause of my problem. I mentioned that this had started when I began my thyroid meds, and we decided to give Armour thyroid a try. Within days, I had energy and felt better than I had in years. Within just a couple weeks, I was off the nebulizer. I feel like a whole new woman. It is VERY difficult to get most doctors to agree to take you off levothyroxine. It is agressively marketed, and most people do okay on it. And doctors will argue that since your TSH is fine, you must be fine. But, in my case, it totally destroyed my quality of life.

I know this is an extreme case, so please don't be alarmed by my story. I just want you to know that you're not crazy to think you might not be reacting to your meds, and there is hope. If you want to PM me for any more info, I would be glad to help. I would hate to see anyone else go through what I did.

Good luck to you. Please let us know how things work out for you.

I do get hives all the time.. from hot to cold temps is usually the cause not medicinally. If I forget to take my zyrtec in the morning, I will have hives at some point during that day.....they are not fun. I hope you can get control of that..

Sorry to hear about your problems. It might not be the active ingredient in the levothyroxine but it could be something in the fillers. It is well known that the fillers in generic levothyroxine also interfere with absorption of the active ingredient. I recently switched from generic levothyroxine to Synthroid and no problems, felt better than I have in a long time and it wasn't too expensive. Personally I think that it is worth it just to feel more like yourself.

Good luck to you and I hope that you feel better soon. :flower3:

I've heard from many people that they can't tolerate the generic as well as Synthroid, and that is why I've chosen to stick with Synthroid and not even try the generic. You might want to give it a try...
Good luck, and I hope you get to feel better with the side effects soon!

I have had hives for a couple of weeks. It's the first time I've had hives in my life and I'm 43. I was taking Levothyroxin 50 mcg. When my doctor recently increased it to 100 mcg is when it seems my hives started. I also started using Gain detergent and I started drinking V8 Fusion, so it could be any of those things. I guess the best thing to do is rule out one at a time. Thanks for your posting.

I started taking a Claritin daily with my thyroid medication. No more hives!!! :rotfl: I'll mention it to my doctor at my next visit, but for right now this is working just fine.

There you go.. claritin, zyrtec, they keep the hives from breaking out.. I also get hives when I exercise....if I forget to take the zyrtec, it is not pretty, not on the face, mostly on the torso and legs.
