SYNTHROID  (LEVOTHYROXINE SODIUM):  Levothyroxine is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone is important for maintaining normal mental and physical activity. In children, having enough thyroid hormone is important for normal mental and physical development. This medication is also used to treat other types of thyroid disorders (such as certain types of goiters, thyroid cancer). This medication should not be used to treat infertility unless it is caused by low thyroid hormone levels.   FDA Approval Date: 2002-07-24 (Sources: U.S. Centers for Medicare Services, FDA)

 4  Total Thyroidectomy due to Cancer none really - bad menstrual cramps first 24 hours of cycle, but other than that can't complain. Before my thyroid was removed, I was underweight and nervous all the time. Now I feel more like what I suppose a normal person feels like - not so agitated. I do find that exercising regularly helps me. F 31 18 months

 4  hashimoto's None as long as I don't take too high a dosage. If you are having depression and brain fog, try cutting out gluten. After years of depression and a more recent bout of brain fog and fatigue, I eliminated gluten from my diet and felt much better. I also lost 10 pounds. Also, my dosage of levothyroxin has changed over the years. I do better when I take the lowest dosage which keeps my thyroid in an acceptable range. F 63 35 years

 4  Hashimotos Heart palpitations when dose raised to 150. It was returned to 137, much better. Also take cytomel, vitamin D for deficiency found. This combination plus taking synthroid 1 hour before eating is working. I have taken synthroid successfully 8 years and my mother is taking it for 28. Most people's comments are not about synthroid. Low thyroid people often have Vitamin D deficiency which is causing the joint pain. After I supplemented with D, the problems went away. Also I had stopped moving because it hurt, went to aquatic exercise and began again. Joints feel better when moved. Also supplement with calcium , triple strength fish oil, glucosamine chondrotin msm and multi vitamin. F 60 8 years

 4  Hurthle Cell Adenoma; part thydctmy Ringing in ears; feeling of hungriness Overall positive thus far; will use synthroid for suppressive therapy, so I will be living with it for a while; nurse told me she tried taking a double dose one time to see if she would lose weight....was bad, she said she was out of control hungry and ate a lot. I can see a potential to eat more in response to the hungriness. Im trying to keep appropriate snacks around. F 49 10 days

 4  Hashimotos Itchy, dry skin for about 2 months, increased bowel movements. Weight did go up a bit at first when on the lower doses. But now back to normal. Doctor started me on 37mcg and after 2 months, moved up to 75 for 4 wks, 125 and then 137. I had major itching and dry skin for about 2 months. Energy wise, felt a bit better (wasn't needing daytime naps) but not amazing. After blood tests (t3, t4 levels) my t4's were a bit high so, was downgraded to 125mcg and Doc added .5mcg of Cytomel. I feel much better, clear thinking, a bit more energy. The plan is to add a second .5 Cytomel in a month. F 46 6 months

 4  Hashimoto;s None, apart from my skin seems to have gotten much more congested, more blackhead etc (should have been the opposite). When on too much, I experience heart palpitations. My hair is still falling out although less than before. No weight gain or weight loss, everything constant, weight was never an issue. I have been on Synthroid for Hashimoto's now for almost 3 years before that desiccated thyroid for 1.5 years. With Armour they just kept increasing it and I felt some change but not significant. Finally a doctor told me there would be no difference between it and synthroid, so I went on synthroid. Again, my dosage just kept going up without a significant improvement. It turned out just recently ( and I figured this out ON MY OWN and had to basically tell my doc what I wanted her to do), just the T4 couldn't be converted by my body into sufficient T3 (my TSH was indicative of this, as it was in overdrive), so I needed cytomel (i.e.T3) added to the synthroid and now I finally feel good. I am now on 112 mcg synthroid and 5 mcg cytomel twice a day. HAving said all this, my current endo has admitted that basically Armour is a natural combination of T3 and T4 (i.e. synthroid plus cytomel) and I think once I am at the right level I will go on it again, just to see if it works as well. I am also looking into alternative ways of healing myself as I do not want to spend a lifetime on synthroid and I am becoming more and more suspicious about the absolute need to take synthroid. Hypothyroidism is a veritable epidemic and I believe it has hugely to do with our diets, supplements and environmental factors. I am just wondering why doctors are so quick to put people on synthroid. I read " How i reversed my Hashimoto's thyroiditis hypothyroidism" by Robert Dirgo. F 38 3 years

 4  born without thyroid As I was born without a thyroid I have been on this drug my whole life. When I was growing up I decided I didn't want to take this drug and always told my mother I had taken it. My doctor told me if I didn't take it eventually I would DIE. He tried me on the synthroid brand and I then started having more energy. I am able to work and play with my 9 year old daughter. Reading the other reviews some people aren't happy with this drug but finding the right dose for you takes time. I have found when I get my dosage upped 100+ it doesn't suit me, I am better on 75mcg or 100mcg. F 29 29 years

 4  Hypothyroidism I am clinching my teeth causing extreme sensitivity to warm, cold, even hard foods-noticed this when i started but figured it would go away once my body got used to it and now it is getting worse. And I am figiting - this just started within the past month. I do not see very many people with clinching their teeth but it has to be this medicine. My problem was caught right as it started acting up so, I didn't have any issues. I was just doing blood work for school and it was caught. So, as far as I know it does its job but the teeth thing is really bothering me and I am wondering if the dose it too high? F 28 1 years

 4  Hypothyroid weight loss, goiter went away, increased energy. Normal BM's. I was diagnosed very young with hypothyroid, It took a long time for my goiter to go away and my weight to even out. Recently I've noticed that my energy has decreased and my neck felt swollen. Just had an ultrasound done, now I have a tiny nodule on the upper left portion of my thyroid. I just had an increase in my dosage from 75mcg to 112mcg. Doctor says it will take about a month or so to notice a difference. I am hoping everything returns to normal and that my nodules remain small and benign. All I can do now is wait an hope for the best. F 23 15 years

 4  hypothyroidism I have a family history of thyroid disease. My thyroid problems were finally diagnosed after I developed severe post-partum depression following the birth of my first child. I found an endo who didn't just look at "are you in the normal range" but looked at WHERE I was in the normal range. I was put on Synthroid when Armour Thyroid was taken off the market. While it was better then nothing, it just didn't work as well as Armour for me. I am back on Armour, thanks to the local compounding pharmacy, but still take 12.5mg of Synthroid daily. While I much prefer Armour, if this was all that was available, I'd take it and work with my endo to get the dosage where I need it! F 42 10 years

 4  hypothyroid none It helped clear up my acne & cold sores, also stopped me from being cold all the time, and my hair was falling out, now it's nice and thick. The only thing that Synthroid didn't do that I was hoping it would was to help me lose the 30 lbs I put on when my thyroid went haywire....so far that hasn't happened. F 53 1 years

 4  half of thyroid removed a year ago I've started to learn my body and symptoms of when my thyroid hormones are getting low or high. Low - get really tired and cold. High - hungry all the time, slight anxiety, trouble sleeping. Heavier periods, insomnia at times. I took the generic of this drug and had horrible side effects, anxiety and panice attacks at the top of the list. Once I started the Synthroid, symptoms starting improving. It took awhile to get the dosage correct. I've now landed at 75 Mg five days per week and 100 mg the other two days of the week. I've started to learn my body and symptoms of when my thyroid hormones are getting low or high. Low - get really tired and cold. High - hungry all the time, slight anxiety, trouble sleeping. The one thing that has been constant since having half of my thryroid removed is weight gain regardless of food intake or exercise. I'm gained 35 pounds since the removal. Synthroid hasn't seemed to help in this aspect at all, matter of fact, the constant hunger when my levels went to high caused me to eat more than I would. Overall, I would recommend this to others. It's given me my energy back, and helped me feel more like myself again, although not perfect. F 37 7 months

 4  Hypothyroidism Diarrhea I had struggled with feeling tired, depressed, gained 10lbs in 2 weeks, developed carpal tunnel, brain fog, could barely function. Tried natural supplements/diet/exercise to no avail so i went to see my dr. He started me on synthroid 3 days ago... Within a few hours I felt like 'the lights were coming on'. It's only been 3 days but I'm already beginning to feel better! F 38 3 days

 4  hypothyroidism blurry vision In 2003 I had my son, about 6 months later I began feeling completely ran down, depressed and so darn tired I coudldn't take it. I made an appointment with my PCP, who almost immediately saw a lump in my neck. She sent me for labs, which came back I was hyperthyroid. I had tests, an uptake with iodine and found that the left side of my thyroid was not functioning. It also had a nodule on it. My ENT decided to do a partial thyroidectomy. I felt great for awhile, maybe a year or so. In 2005 I began feeling depressed, was sleepy all the time, just not feeling like me. Had my labs checked, as I did every three months, but levels always came back within normal range. I changed so many doctors even though I had an HMO, but each one of them was the same. They didn't give a hoot about me or my thyroid levels. In 2011 I got married and went on my husbands health plan, a ppo. And guess what? Mysteriously I became hypothyroid. Interesting how that works. Even if it is a coincidence, I am glad my new doctor found it and put me on this medication. I'm sure we will have to figure out which dosage is right for me, but so far...I'm able to fall asleep at night, my depression is almost all gone, and I'm just happier all around. F 32 3 weeks
