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)

 5  Hypothyroidism I experienced no severe side effects. Synthroid and Armour Thyroid helped me to lose 30 pounds within a year. I've felt a thousand times better--have much more energy, feel less depressed and anxious and have fewer cravings since taking synthroid. F 49 1 years

 1  hashimoto hypothyroid Levothyroxin worked great when I was first diagnosed. I lost weight and had more energy, etc. Then in Oct 2007 my Endocrinologist put me on Synthroid and I've gained about 20lbs, I work out every other day and I'm seeing #'s on my scale that I've never seen before. I have severe joint pain, tired, must take a nap during the day and most recently I have been sweating a lot. I found a doctor in Connecticut that uses Armour which has been around since the turn of the century and Synthroid has only been on the market since the 70's. Does anyone know of a doctor in the Charlotte NC area that uses Armour? F 50 2 years

 2  hypo I just started taking synthroid, 25mcg and I am scared to death!! I have weight gain, fatigue, visual disturbances, moody. I can't imagine getting worse on this drug. My doctor just perscribed it. I wanted to know more so I found this sight and I am in shock about the lack of success w/this drug. I don't know if I should take it. I'm 40 yrs. old and in general good health, w/a raised tsh of 5.57, and all the nasty side effects of hypo. How long before I notice a result, either for the better or worse? If I get moodier or gain more weight or lose more energy I won't be able to function.I also have insomnia and very, very, heavy periods for the first couple days w/out taking synthroid. Very concerned. F 40 2 days

 3  Hashimoto's Thyroiditis LACTOSE INTOLERANCE BIG TIME!!! This medication caused so many problems for me. I took it for years and never knew it contained lactose. I always recommended Synthroid until I started having lactose intolerance problems due to under treated hypoT. I found the detailed version of the drug information and found it had lactose in it. Shock! I switched to Levoxyl and I'm glad I did. No more problems with my stomach. Now if I could just get my hypoT under control I'd be happy. F 54 4.5 years

 2  hasimotos diarreah, mood swings, exhaustion, not sleeping well, chest pains/tightness, libido lack, depression, irritibility I started on this after family history of hashimoto's and several miscarriages. Thankfully, after being on synthroid, I was able to conceive and keep a child. However, I just found out today that my tsh is within normal range and I feel worse than I ever have. I've been reading the comments on here, and though they are comments and I can't take 100% to heart, it has persuaded me to do more research and talk to my doctor. I've even had chest pains so much to the point that I was diagnosed as having a genetically induced heart attack (which means I had a heart issue from SVT's, but they can't find a reason why)- I'm a 30 year old female - so that is not common! After reading here, I'm finding that everything may be linked to the drug. So, while I'm upset that I feel worse, I'm excited that maybe with a little questioning, I'll get better and my marriage will be saved! F 30 2.5 years

 4  Grave's disease occasional hot flashes This medication works great for both forms of thyroid disease. Side effects are usually moderate for the first few doses and mild thereafter. The generic levothyroxine works just as well as this drug and is much cheaper. F 17 2 years

 4  Hypothyroid the synthroid made my side effects go away for a few months then they would come back. Insomnia was my side effect i always got when i went up a dose. Synthroid makes me feel great when it is working! i felt like a new person when i first started taking it. i started on .025 and am up to .200. The longest I had my thyroid regulated was 1 year. recently my TSH was 13 so thats when my dose went up again. right now i am having insomnia but im less angry and irritated all the time and can tell the new dose is starting to help me.

 1  hypothyroidism hair loss, exhaustion, heavy periods, brain fog, mood swings, suicidal depression, misdiagnosis of bipolar disorder, lost my eyebrows, dental problems this stuff does not work. Abbott Labs is the devil. They invented the TSH test to make their drug 'necessary.' Find a doctor who treats by symptoms and prescribes natural hormones F 45 3 years

 5  Hypo - diagnosed with a TSH 7 None that I'm aware of(at this point)- but will be watching - I do wonder about the weight issue. By the time I was diagnosed (approx 9 months ago)- I had dermatitis, weight gain (& hard to lose weight), depression, dry skin, hair thining, face skin deteriating, sensitive to cold, sever fatigue, muscle/joint aches, increased cholesterol levels and memory loss (I was a mess - and classic for Hypo-Thyroid). The Synthroid dose has been adjusted over time - I'm currently at a dose of .100 - TSH .91 (stared with dose of .5 - TSH 7). The Synthroid has helped me GREATLY. I do hope that it continues to remedy my symptoms. But like all substances that we ingest - some work and some don't dependent upon our own individual physiology. Right now I'm happy with it. F 58 9 months

 4  Hypothyroidism With synthroid, I have none. I took the generic for a while, and after a while, I ended up constipated and miserable. I had to go back to the name brand. My only complaint is the cost. It is much cheaper to use the generic, however, it isn't worth it. I have more energy and don't feel so constipated and bloated! F 27 5 years

 2  Hypo weight gain,muscle ache, extremely tired, 14 days before period I felt cramps, increased eating habits. I get cold easily. I have been taking Synthroid pill since March 19,2008. I have not felt better... instead I feel the opposite....I am thinking of stopping it as soon as possible... as I dont want to prolong my side effects....my doctor advised me that this would make me feel better..maybe for some but not for me,. I will advisemy doctor that I will not continue on this medication. F 34 15 days
