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/Hashimoto's About 7 years ago I felt sick all the time - sore throat, muscle aches, headaches, joint pain - so my doctor kept giving me antibiotics but I never felt better. I also felt extremely tired, irritable, depressed and my hair was falling out - even my eye brows and eye lashes. My skin was so dry - I would put lotion on every day and still it would crack and bleed. Finally one day my doctor felt my thyroid and noticed that it was quite enlarged. He sent me for the blood test and when the results came in he called me at home and told me to start taking the medication right away because my TSH was 91.37!!! He said he didn't know how I was getting out of bed in the morning - I said I don't know either! As soon as I started taking it I felt more energy but it only lasted a few days then every time they increased it I would feel more energy until now I'm at the total replacement dose. My hair grew back, I have some more energy - still not a lot but at least I can get out of bed in the mor I also used to be cold all the time - any time you would touch my hands they would be freezing. Now I am hot and sweaty all the time. Not sure if it's from the thyroid meds or from my diabetes but that's another issue. I take the generic, Levoxyl because my nutritionist didn't want me taking Synthroid due to the dyes in it. Now my TSH is .25. Some endocrinologists say that's too low but I've talked to many who focus on holistic medication and they say that you can't always go by the "normal ranges". What's normal for me may not be what's normal for someone else. All I know is that 200 mcg works for me. If I go down to 175 mcg, I feel the differece. F 32 7 years

 5  GRAVES/ HYPOTHYROIDISM none I was diagnosed with hyperthyroidism and was given radioactive iodine. The purpose of this Radioactive iodine is to take you to hypothyroidism. After waiting several months, i began noticing that my hair was falling out so much that it was scary and i felt so tired. These symptoms were nothing compared to those i had while i was hyperthyroid. I had blood tests and was now diagnosed with hypothyroidism. My doctor gave me synthroid.It took a while to get the right dose. I am so satisfied with the results that i can tell you i feel MYSELF again. Goodbye depression. F 28 3 years

 5  Thyroid surgery to remove goiter None Works great. It is the one medication that all of my doctors have told me to get ONLY Synthroid and not a generic and there is a difference. All other drugs I take generic when it is available. I had also read about synthroid vs generic brands so there must be something to it. At least it isn't expensive! F 58 4 years

 5  hypothyroidism none I have always taken 50mcg even though I was told I would need to increase it and my TSH is still going down. Does anyone know if maybe my thyroid was injured during heart bypass surgery and perhaps has now healed? My doc does not think so. got my TSH from 6.8 to 3.2 in 6 months and from 3.2 to 1.6 at 18 months. My doctor felt I would have more problems later unless I started the synthroid now. I did not have any symptoms so I still wonder about it but the blood test show a big difference in the TSH so guess I did need it. F 64 3 years

 5  hypothyroidism None Have taken this for over 21 years. It's been so long that I can't recall the fatigue I used to feel, I dropped about 25 pounds after starting on the Synthroid all those years ago and it has helped me maintain my weight within the same 5 or so pounds all these years, when prior to that I tried and tried to loose weight but couldn't get it to budge. It must have revved up my metabolism. F 49 21 years

 5  hypothyroidism No side effects. Constipation was prior to synthroid & is normal now...however, I recommend more fiber in a diet....or fiber supplement. My life has changed since I have been perscribed sythroid .075 mg is a small dose, however, has made huge health changes for me. I am no longer bloated, shortness of breath, tired, feeling like having the flu, body temp was low & normal now. 10 yrs telling doctors I wasn't feeling well...their response; "what I can see all is fine". Never a blood work-up taken or suggested. Having joint pains & seeing a Dr. for ho joint pains. This fabulous, caring physcian spent 2 hr extensive meeting & took blood work and found the problem that I had hypothrodism. I thank him & the lord a finding the problem. I feel wonderful and healthy now. I have fabulous doctors now & feel 15 + yrs younger. Taking sythroid for 6.5 yrs and still improving. Very important take sythroid the same time each day... by minute on the clock....not taking (skipping) or taking even 1 hr late....I become constipated and notice the change. Watch that clock & take on time! Sythroid since: 7/18 /00 F 56 6 years

 5  subclincal hypothyroidism energy, much easier to get out of bed, improved memory/thinking, better balance, caffeine sensitivity, racing heart, some nauseau, some hair-loss, some weight loss, increased appetite, extra motivation, trouble exercising the first few weeks. Overall, I'm very happy with the medicine, I'm currently taking .25mcg of Levothyroxine. By the third day I noticed extreme energy and the inability to sit still. The energy was great, but a little much at times. Now after 5 weeks I've calmed down a bit. It's still much easier for me to get out of bed, my memory is noticably improved. Also it took about 3 or 4 weeks before I didn't feel like my heart was beating too fast when I exercised, and my endurance is getting back to where it was. I had no idea I had hypothyroidism before taking a bloodtest 2 months ago. Even after learning I had it I was a little hesitant to take medicine for it, when I didn't think I had many symptoms. Overall I'm very happy with the effects, and so far am very glad I decided to take levothyroxine. F 27 5 weeks

 5  Hypothyroidism I experienced continuous bleeding. It's not known if that is from the Synthroid or some other problem. (We'll know soon.) I've only been on the medicine for three months and have gone back to my normal, energetic life. I went three years before I was diagnosed. I had symptoms of weight-gain, chronic constipation, sensitive to cold (I'm one of those always-hot people, so this was a big one!), fatigue, hair loss, and dry skin. My life is back to normal now after only three months. It's a lot easier to diet now. (I've lost 10 pounds.) Before the medication, I would practically starve and would still NOT lose any weight.

 5  hypothyroidism NONE! I am one who has side effects when I take Tylenol, so it was with great trepidation I started a new medication. I have had ONLY POSITIVE SIDE EFFECTS! I think some people with these negative side effects may have too high of a dose ( or too low ) or other concurrent problems needing to be addressed. For me, I am finally BALANCED! So far I have felt better in the last few weeks than I have in the last few years! My doctor has me on a low dose which seems to be working very effectively. I will be tested again soon at the three month mark. I suffer from anxiety attacks for which I take Xanax, AND I am prone to get the worst case side effects from almost anything I take. I was apprehensive this medicine would rev me up and make me jittery! I do have energy to spare, but it is a good energy- an optimistic and "full of lfe" feeling. My anxiety has DROPPED! I sleep better, my mood is better, I am only sorry I did not get on this sooner! F 43 1 months

 5  hypothryroidism No side effects that I'm aware of. Levothyroxin the generic version is what I'm on. It put my thyroid in balance. By time I got to the doctor to get checked out my tsh was 11.93. Within a month on this drug it is at 3.5. F 60 6 months

 5  hypothyroidism None that I am aware of. I have been taking the same med, synthroid, since age 11 when a goiter was discovered along with hypothyroidism. They said I will on this for the rest of my life, which must be true because I am 39 and still on it. I notice that I have a low body temp usually, get cold easily, and have trouble losing weight. Other than that, no real issues. F 39 28 years

 5  hypothyroidism The thyroid gland affects every part of your body, skin(oily, or dry, acne or exema) hair, bones, nails, cotton mouth, mood (low sex drive, lethargy, suicial tendencies, anger issues) heart rate, weight gain or loss, metabolism, energy, brain function, sleeping all the time or insomnia,feeling too cold or feeling too hot, uncontrollable sweating, muscle atrophe, soarness, retaining water, excessive fat tissue. The list goes on, but the one thing that is not to blame is synthroid. This drug is only helpful to people with this defect. One thing that is not fully understood is that everyone has a different level they need to be on, and the manufacturer doesn't always make that perfect dose for your particular case, and doctors really don't fully understand that a couple of mcgs can make alot of difference. If things aren't working for you than you have to experiment with taking maybe a 135mcg, along with a 50mcg, or a 100mcg along with an 88mcg. Your doctor will work with you, but you hav F 47 39 years

 5  hypothyroidism None at all I take 200mcg. I have taken it for 6 years. If there have been side effects, they have only been positive: I am able to lose weight if I try, I am not freezing to death all the time, and I am not ready to hibernate for a long winter's nap by noon each day. Synthroid is great. It has completely changed my life for the better. F 39 6 years

 5  hypothryoidism Slight fluttery feeling in my chest the first and second day on 25 mg dose. From all I'd read and heard, even from my doc, I expected to wait at least a few weeks to see any improvement. Instead, I noticed significant improvement on Day 1 and it has only gotten better in the 3 days since. I don't have that crippling brain fog (that was serious impacting my job performance), have energy to spare. The joint aches are gone, I sweat again, my recovery time from a gym workout is back to normal. I am astounded and very grateful. I go up to 50mg in a few days and will update this then. My thanks to all who posted before--your comments (-and +) helped me a great deal! F 44 4 days

 5  Hypothyroidism Ive never noticed side effects from this drug -- negative or positive. I felt great in my early 50's -- assumed I was in perfect health -- when my GYN routinely discovered a goiter. I was sent to an internist who put me through numerous tests and subsequently prescribed Synthroid (and told me never to take the generic brand). I've never felt any different than the day I began taking the drug, however, I see the annual test results so I'm sure I need it. My dosage has increased several times; I presently take 150mcg. I've developed aches and pains in the last 10 years, but at my age who hasn't -- and Synthroid probably has nothing to do with it. F 63 10 years

 4  hypothyroid reduced appetite? it's only been 3 days so that might be just a coincidence After at least 6 years of my doctor writing off my fatigue as a one of the symptoms of depression, I finally got a doctor who did the thyroid testing I asked for. Of course, I had to twist his arm too…what is it with doctors not wanting to go beyond the basic testing? I’m only on day 3 with Synthroid, still have fatigue, but decreased appetite. Anyway, I’m looking forward to being able to get through a whole week of work without leaving early to go home and sleep. F 32 3 days
