Levothyroxine and working in the heat

I have been on levo for 2 1/2 years. Started at 75 for about a year and a half. I got a new dr and dose was upped to 100, then 125 for last six months. I have also been dealing with menopause, I THINK. In the last 5 months I have had trouble falling asleep, jittery, nervous energy. I have worked outdoors in the heat with no problems. Now that I look back, I have had a hard time in the heat since I started levo. A couple months ago I weaned off of cymbalta and after those withdrawals were over, I started getting naseau and migraine. Has anyone else experienced heat problems? And is there a natural med for hypothyroidism? ## Hi Lisa, Sorry to hear about your situation. According to the US National Library of Medicine, "sensitivity to heat" is listed as a serious side effect of Lev...

Sandoz Levothyroxine

Recently filled a prescription for Levothyroxine 150 mcg and noticed a very fowl smell and ultimately a slightly different taste when taking it. One side of the pill is marked with "150" and the other side with "GG338." We questioned the pharmacist about this and they opened a new bottle that smelled the same to us, but she didn't smell anything so nothing was done. I know Levoxyl was discontinued for a while for this very problem. Is there any information out there about this Sandoz product? ## If you had a chance to read the FDA recall information, the odor it was recalled for was actually due to a problem with the absorbent canister that was packaged in the bottles, not the pills themselves. However, the odor was not found to cause any adverse health issues, or pr...

Swelling in legs and feet levothyroxine

I just started taking Levothyroxine 2 wks ago my legs and feet are swollen so bad by nite I can barley walk. They go down a little at nite but swell back. I am taking 25mcg and I am afraid to continue taking this med. Has any one else had this problem? ## Have you contacted your doctor? It sounds like you might be having a bad reaction to this medication and it may not be the right one for you, or may be too high of a dosage. Generally, the symptoms of a dosage being too high will start to manifest 6 days or so, after you start taking it and this type of fluid retention can be one of them and there is a chance that it could lead to congestive heart failure, if that's what's causing it and it isn't rectified. You should really contact your doctor immediately. ## I am on medic...

levothyroxine for mood disorders

I was recently prescribed an ultra high dose (300mcg and climbing) by my psychologist for a mood disorder. I guess this is a relatively new treatment. Just wondering if anyone had any thoughts, stories or warnings about this? ## What is the mood disorder? I've never heard of this, but I will ask my psychologist why a person would take it, next time I see him. ## High doses have been used to treat some cases of Bipolar Disorder. The FDA lists the typical side effects as possibly including nausea, dizziness, headache, weight changes, and hair loss. How are you doing on it? Has it helped? ## This is a medication for Hypothyroid disorder (Underactiv thyroid). It seems strange to prescribe this for a mood-disorder. 300mcg (microgram) of Levothyroxine will put your heart and whole body in...

using expired Levothyroxine

I had been on the same levothyroxine prescription for about 25 years. In the last 3 years my medication has had to be readjusted 3 times. Now I am back on a lower dose and wanted to know if I can still use the previous, leftover supply that has expired about 1-2 years ago? ## Hello, Laurene! How are you? Medications tend to lose effectiveness over time and since treating a thyroid disorder is so touchy, it would be best to dispose of the expired ones and obtain a new supply. The FDA lists the typical side effects of this medication as possibly including nausea, dizziness, hair loss and weight changes. Is there anything else I can help with? ## Thank you for your feedback on using expired levothyroxine., ## What effects would I feel if taking expired thyroxine ## whats the side effects i...

Levothyroxine side effects

I was recently diagnosed with an underactive thyroid. I have been taking levothyroxine for almost two weeks. For the last four or five days I have had a weird feeling. It is hard to explain. I don't really feel dizzy but I get a strange feeling in my head. I guess you would describe it as a head rush. Has anyone else had this feeling and will it go away as my body adjusts to the levothyroxine? ## yes i would get that every morning after i took my pills and drank coffee. I think its inmortant to eat a little over an hour after to avoid the dizziness. It does go away though. ## Levothyroxine Info and Side effects Click Here ## my pharmactist changed my thyroid pills because my insurance doesn't cover my other ones. I am cold all the time again and i am dizzy. I came home from work...

Carbimazole and Levothroxine

Hi there. Why has my doctor prescribed both Carbimazole and Levothroxine to be taken on the same day? ## How were your thyroid levels? Sometimes, multiple medications might be prescribed to help lower levels as fast, and as safely as possibly. The NIH lists the typical side effects as possibly including nausea, dizziness, headache, weight changes, mood changes, and hair loss.

Hoarseness Side Effects?

I was diagnoised with hypothyroidism last December and was put on Levothyroxine (75mcg). Overall I have been feeling better and have more energy. But unlike most other people with underactive thyroids I was not overweight and since going on Levothyroxine have lost 10 pounds and am continuing to lose weight. I also have developed hoarseness which gets worse as the day goes on. Question-the weight loss is a common side effect of the medication-but has anyone heard of hoarseness? My thyroid levels were tested a few weeks ago and are now normal. ## Yes, I have noticed sore throat and hoarseness also on generic levothyroxine 75mcg. I finally tried not taking it for a couple of days and the sore throat and hoarseness went away. Started taking it again and voila, the sore throat and hoarseness...
