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)

 3  Hypothyroid Stomache pains, headaches, aches and pains, nausea, diahreah I just started taking this medicine about 2 months ago and at first I felt great. I had a lot more energy and was very upbeat. I had some minor stomache pains but they didn't last long. Just this past weekend, however, I started having severe stomache pains, nausea, aches and pains all over, headaches, trouble sleeping and diahreah. I stopped taking the medicine 3 days ago and the doctor wants me to go in for more blood work. I am hoping this is only a temporary set back as I really enjoyed the extra energy I had when I started the medicine. F 42 2 months

 3  Thyroid cancer/thyroidectomy Depression, fatigue, headaches, chills, constipation, low libido, weight gain, unable to concentrate. I was given my first dose of Synthroid in November 08, after I completed my radiation iodine treatment for papillary thyroid cancer. Was given 112mg and never really felt awesome, just in between. Some days were hard to get out of bed, others were not. Dr. upped my doseage after seeing my thyroid bloodwork levels weren't adequate enough. Have been on 137mg of Synthroid for about a week. My headaches are worse, I have cold chills, muscle aches, very low sex drive and a hard time concentrating. I've also been constipated for about two months now. I have yet to have the energy levels I had before I was diagnosed with thyroid cancer in September 08. I gained 40lbs in the past year and a half because of my thyroid issues and even with Synthroid, it's still really hard to lose. I will give my new doseage proper time for my body to adjust to it before I can make any statements about Synthroid, 137mg. F 22 60 days

 5  Hashimoto's thyroiditis None When first diagnosed, I had severe pain in my chest, dry skin, hair falling out and my emotional state could have been almost described as psychotic. My TSH was >200. I was put on Synthroid at age 26 and it's been a lifesaver. My hair and nails now grow at lightning speed, my skin is still slightly dry, but probably due to getting older. No joint pain and emotionally, I feel "normal" (lol) . I switched at one point to generic Levothyroxin, but it was not for me. It lent to instability of my levels so went back to Synthroid.

 3  Hypo When first taking it about 9 years ago, things were real good. Felt good, had allot of energy. Not that much any more. About 5-6 months ago I started having problems with my throat. In a few days, I will see a doctor about some tests. It feels like someone has a hold of my esophagus and I am always clearing my throat and also snore real bad. M 49 9 years

 3  Hashimoto's Thryoiditis None to speak of. Taking the generic form Levothyroxine. Except that I am usual quite regular with the monthly cycle and now I am not having one and I've only been on the meds for one month and this is the first period missed or prolonged in well over 7 years. I am unable to send an email to the female who submitted on 12/8/08 stating she has diarhea, and feels like dying, cold all the time. I had that. I also have exhausted adrenal glands and whenever I take the supplelemtns to help me with that, those symptoms and feelings go away. She should go to her doctor and get her adrenal function tested. Many Hashimoto's patients apparently can have adrenal problems also. Please tell your doctor to test you!!!!! Insist on it!!! F 51 35 days

 1  hypothroidism Lots of unexplained weight loss; extreme fogginess; lost appetite; increased abdominal pain; constant fatigue; anxiety and prevailing sense of doom. My gp put me on synthroid 50 mcg for first week, then 75, then 100. I felt better and better until a few weeks ago when I began to get extreme foggy-headedness (just like being on drugs), memory loss, horrifying anxiety (prevailing sense of doom) waking me up ALL night. 0% concentration ALL THE TIME. Constant fatigue. Feel cold all the time (with decreased body temp). Rushed to the ER 3 days ago with chest pains, breathing difficulty and extreme foggyness. ER ct-scanned my brain, upper resp, took a gallon of blood and sent me home. I feel like I am going to die all the time. I thought that I was dying until I found the vast number of synthroid users that experience some or all of the same symptoms. I've been synthroid free for 2 days now almost and have vague signs of improvement. M 35 7 weeks

 3  thyroid removed tired all the time, cold all the time, irregular heart beats, mood swings, and weight gain I had my thyroid removed when I was 18 because I had cancer. Before my surgery I weighed 120 pounds and since taking synthroid I've gained 30 pounds and no matter how much I exercise and diet I can't get back to my original weight. Also, In the past 4 years I've been back and forth between 5 different dosages because they can't figure out which one works for me. I just wonder if anybody else has had as much trouble as me figuring out their dosages. I know that I need to take this, I'm just tired of having the way I feel by what dosage I'm on. F 22 4 years

 2  Hypo For the past two years I have been on Levothyroxine 50mcg. My primary doctor disagnosed me with hashimoto disease. About 6 months ago, I visited with an endo doctor my levels were good. On November 18th, he took blood work and all was good but he prescribed Synthroid 50 mcg. I've been feeling a bit irritable and slightly depressed but mostly irritable. Is this normal when switching from generic to synthroid and seem to also have a buzzing headache on the right side. I was completely fine on the Levo but you guys tells me. F 39 21 days

 1  No Thyroid See my posting on 8/26/2008 Finally I found a doctor that would perscribe Armour. I've been on it for about 7 weeks. First two weeks off Synthroid and on Armour were the same. 3 & 4 week horrible. I felt like I was detoxing, but hung in there. Each day got better. Did turn out that it was too much of dose. They have reduced it and am still feeling a little better everyday. Bones have stopped aching! After 10 years of Synthroid I don't think I will be going back EVER! I know it's still to soon to really, really tell. But my face is less puffy and I am not retaining water like before. Research Armour and see an Osteopathic doctor if you can. Don't let your doctor belittle you. Only you know what is happening. Not all doctors are right about everything. Please read what I felt like before on 08/26/2008 Age 31 and you can email me if you have questions. Good luck all. F 31 10 years

 2  Hypothyroid Tired, anxiety, depression, cold ALL THE TIME, can't put my thoughts together. I have always been a person who is upbeat and who sees the brighter side of life. This is effecting my relationship with my husband, my children, and everyone around me. I am irritable all the time and when I wake up it just seems like I am ready to pounce on anyone who is around me. I never have any energy and working two jobs requires a little more energy than most people. I don't know what to do. F 38 1 years

 1  Hypothyroid Diarria, anxiety, feeling unwell, ready to die. This was after my increase. Before the increase I felt so heavy I couldn't walk without feeling I was falling to the floor. The increase has increased my energy, but now I can't sleep, my legs need to keep shaking all night long, severe diarria, and I am losing hope for every feeling well and just want to die.

 2  Synthroid Hair loss, chronic fatigue, brain fog, mood swings, weight gain, aching muscles and bones, eyes swollen I have been taking Sythroid and the generic brand for years and still felt terrible. My dad was switched to Armour and raved about it. Two years later, I am finally on it and noticed a difference in ONE day. I regret that I did not find a new doctor sooner because I am feeling like my old self again! I finally have energy, the brain fog is lifting and I no longer feel depressed. Check out ARMOUR thyroid. You will NOT miss Synthroid. F 34 8 years

 1  hypothyroid weight gain, bloating, puffy face, fatigue, constipation e.t.c My TSH was 4.1 and my doc gave me synthroid 100mcg to try for 3 months. I've tried to take Syn 3 times and I've never lasted longer than 2 weeks. On Syn I would start to bloat by the 3rd day, gain weight and feel worse than before taking it... I HATE THIS STUFF!!! it makes all my hypo symptoms worse!! F 31 2 weeks

 4  Thyroid Cancer / Thyroidectomy At onset, I experienced weight gain, hot flashes, brain fog, moments of fatigue, and headaches. Symptoms only lasted about 2 weeks then tapered. During the past 4 years, on two separate occassions, I stopped taking synthroid on my own, only to throw my body out of synch. My cholesterol levels went up, and so did my blood pressure. When I am taking my 137 mcg daily, these symptoms subside, and my cholesterol and blood pressure levels normalize. F 51 4 years

 4  total thyroidectomy/ thyroid cancer Hair loss, night sweats, inability to sleep. Never had the energy I was supposed to have after my thyroid levels were evened out. I started out taking the generic, but then my endocrinologist gave me a few months worth of samples of the name brand, and after only a few weeks the side effects disappeared. I didn't actually notice until the samples ran out and I had to get the generic refilled. Then I started noticing my hair falling out again, and I am waking up with cold sweats at night. Am switching back to the name brand this week to try and fix it. F 26 1.5 years

 4  hypo I haven't lost weight, but I've stopped gaining weight. Extended stomach. Hair loss at first. I feel great on 75mgs (mentally and physically). I wish I could lose some weight and my stomach would go down, but I'm not sure those problems are due to the medication. For those people not getting good results, it may be they are taking an incorrect amount or not taking the medication properly. This medication must be taken on an empty stomach with plenty of water and one should wait 30 min.- 1 hour before eating. When I get my blood work done, results have been perfect since taking Synthroid. F 62 18 months
