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 Improved mental energy, physical energy, no longer freezing all the time, able to budge the scale downward. Did not know life could be this good I started out taking 25 mcg., and over the course of 10 years, have finally found the perfect dose for my hypothyroidism: 200mcg synthroid and 24mcg Cytomel (for T3, look it up on this site). My Dr. is excellent about tweaking my dose based on HOW I FEEL rather than just what the official ranges are. I stay just a hair out of range b/c this is where I feel best. My Dr. realizes that nobody knows better how I feel than me. If yours doesn't subscribe to this, switch Drs. Tweaking your thyroid medicine can make a huge difference in your quality of life. Ignore the naysayers on Synthroid. If they have bad side effects, their dose is probably just wrong and they are being alarmists. F 43 10 years

 5  hypothyroid I have had no side effects but needed dosage change throughtout the years I was diagnosed with hypothyroid 47 years ago and have been on this wonderful drug for that many years. I have to have the dosage changed periodically because of stress or other sypmtoms of life changes. You know your body and when you are getting symptoms of fatique,loss of memory, anxiety ,weight gain etc call your doctor and get a blood check, if there is no change then your symptoms are the best sign and ask for small dosage change and see if it helps. I have all the confidence in this drug and know that other health problems can effect thyroid or you may have other meds for other problems beside the thyroid,. Get to the best endocronologist you can and make sure he or she is willing to work with you and your symptoms F 57 45 years

 5  partial thyroidectomy for toxic nod No bad side effects except horrible eye twitching. I've read elsewhere this is common however Drs won't recognize. Can't take at night as kept me awake. Yes I gained weight, but when I was hypERthyroid could eat anything and loose weight. Now synthroid slowed my metabolism to where it should be so I gained 7 lbs in 1 month, but have stayed that weight even w/ no exercise. Now 130lbs. I still have other half of thyroid (cold nodules, could be dangerous down the road)hoping it would take over and wouldn't need replacement therapy. Maybe it is helping with numbers and weight. After surgery my TSH was 7. Make sure take on an empty stomach and make sure no calcium intake w/in 4 hours of taking Synthroid or it (Synthroid)will loose its effectiveness. If you have muscle soreness is a symptom of hypo. It is expensive even on insurance $25/mo. It is recommended that you go non generic w/ something that needs to be precise like this. Good luck.

 5  Subtotal Thyroidectomy None The important thing is that you must take this medicine exactly as prescribed and at the same time every day. Get lab tests every 3 months for the first year - if it stays okay, then the following year do every 6 months - then a few years after that you probably only need a test annually. Your body makes/decreases its own thyroid hormone, so if it can't be regulated easily, it may not be the medicine, it may be your own body. Symptoms such as hair loss, dry skin, etc. is a sign that your levels are off and you need a test to readjust your synthroid. DO NOT USE the generic form of Synthroid - because it is in mcgs instead of mgs, it seems that the generic companies do not take much care in making sure every pill is exactly the right amount.

 5  Hypothyroidism I had no negative side effects with this drug! All positive. I was slightly depressed and stressed before I started taking it and I feel extremely better. I was having heart palpitations due to my heart working too much (from the extra work my thyroid was doing) and those have completely gone. I have absolutely no bad side effects with this. It worked perfectly. F 17

 5  Hashimoto's Nothing bad at all ... in fact, I feel much better now than when I was taking Nature-Throid dessicated T-3 hormone. I haven't been on Synthroid very long, but so far it's been a wonderful experience compared to the Nature-Throid. The dessicated hormone gave me horrible palpitations and sleeplessless, likely due to the fact that it's T-3 rather than T-4. Thyroid medication is tricky, and requires an endocrinologist who knows (and cares) what s/he is doing. Many of the people who have posted here give me the impression that they are either not on the correct medication, or their dosage is off. Not everyone can tolerate the natural thyroid, nor does the synthetic work for all people. I react negatively to so many meds, I was extremely worried about this one ... but so far, so good. This is the first time I've felt like a whole human being in years. I can sleep, I have energy, I'm not freezing all the time, I'm not anxious, I can think straight, the palpitations I had on Nature-Throid have gone away, my joint pain is fading, my appetite is better (and now I don't have to starve myself to keep from gaining weight, which is fantastic). This medication has been a life-saver for me. F 56 3 months

 5  Thyroid Cancer Total Thyroid Remova This changed my life! One endocrinologist insisted my 80 pounds of weight gain in 1 year was due to my personal 'lack of self control' and he recommended I get a lap band! I was on 30mcg at the time, with NO thyroid due to thyroidectomy. New Endo, new drug amount and POOF within 7 months I lost 60 pounds, energy returned, life restored and I would never live without it!! Prior to proper dose I had blinding headaches, muscle cramps, low energy, falling-asleep limbs, swollen fingers uncontrollable bouts of crying/emotions. EVERYTHING that was NOT me!!! Proper dose gave me my life back and I'm back to everything physical I could not do! Don't ever want to live without it!! F 40 1 years

 5  Hypothyroidism No side effects that I've noticed. Was just increased to 75 since my thyroid levels were off again. I put on probably 10 pounds in the last 6 months but in the 1 month since I've increased my dose, I've lost 8 pounds already so I guess it was my thyroid keeping the weight on me. Thankful that I had labwork done last year and found that I had hypothyroidism because since I've been taking generic synthroid, I feel much more energetic and with the increased dosage, I'm losing weight and sleeping better.

 5  Hypothyroidism - Thyroid damaged None I'm on natural Synthroid (much more expensive), not synthetic Levothyroxin. Over the counter vitamins do nothing for me. Herb based vitamins do work for me. I would not stabilize on Levothyroxin. I did on Synthroid. Before hysterectomy was on 175 mcg. After hysterectomy rapid weight loss (2 pounds a week) and heart palpitations. Reduced dosage cured that. Tried Levothyroxin after stabilizing after hysterectomy, sent me into imbalance. Back on Synthroid, stabilized but not loosing weight. F 56 18 years

 5  Hypothyroidism - Hasimotos Weight loss, increased appetite, occasional insomnia I have been on Synthroid since my doctor realized I hadn't been growing like I should be at the age of 8. Taking this drug completely changed my quality of life for the better, and I don't know what I would do without it. I also found that taking it in the morning may help overcome any insomnia, and also taking this prescription within hours of any iron pills usually caused stomach pain. F 19 11 years

 5  Total Thyroidectomy Brain fog on 125mcg, Sweating and heart palps on 137mcg Attn: hasimoto's patients who are disatisfied. Please understand you have an autoimmune disease. I suffered from Hashi's for 12 years with no thyroid meds and suffered the same symptoms all of you are describing. do not be afraid of thyroidectomy, GET IT OUT. As long as you have a diseased gland in your body, meds or not you will have these symptoms. If you have Graves, do not be fooled by RAI, the diseased gland is still in your body. Please see all the positive comments from other TT patients on this site and make that decision for yourself. I FEEL GREAT on synthroid and no more diseased gland. No more symptoms...I have my life back. I worked with my endo and am now on alternating day therapy. Results: perfect!! F 41 6 weeks

 5  TT (cancer) Intially only side effect was sweating. Now that dosage has been corrected, everything is fine. I have lost 35 lbs. through correct eating and exercising during the past 7 months. This drug will not make you gain weight. If you eat too much or don't exercise you will gain. I have not felt this good for quite a number of years. F 52 1 years

 5  Low Thyroid NONE other than the first 2 days or so i was itchy and had leg cramps ABSOLUTLY LOVE IT! The moment I started taking it i felt wonderful. I've forgotten to take it once and I was mean, depressed, dizzy and verrryyy tired. But I couldn't imagine my life without it i'm so happy! Don't read these reviews and be scared out of taking it like i did. take it and see how you react to it. everyone is differnt. I read these reviews the day that the doctor gave it to me and it scared me so much that i debated taking it. F 17 7 months

 5  hypothyroidism weight loss, immediately after starting the medicatioon i'm sure synthroid works well for some people, but not all. everyone is different and will react differently to different types of meds. perhaps these people that are not experiencing weight loss, but gaining weight instead, are not at their proper dosage. since starting synthroid, i am losing 1 pound every 1 to 2 days, just as my doctor said i would. i also know someone else that is hypo and is on synthroid for about 9 years now, before taking it he was obese before he was diagnosed. he is now about 100 pounds lighter since starting synthroid. hope my input helps those that were scared by some of these people that put synthroid down.

 5  Hypothyroidism Infrequent heart palipations, weight loss, increased appetite, stomach problems I was miserable for about 2 years before I was diagnosed with hypothyroidism: weight gain, sensibility to cold, fatigue, depression, slowed thinking, constipation, loss of appetite. After starting to take synthroid, I felt more energetic, happy and lost some weight. It took about 6-8 months of slowly uping my dosage before I stabilized. I had some heart palpitations when changing dosages, but now that I am on same dosage no problem. I still have some hot/cold flashes and stomach problems, but it is worth it to have energy to live! It has worked for me, but everyone is different. F 26 4 years

 5  Hypothyroid Side Effects? What are those? :)I can only see positives. Usually I come to this site to see what others think of a drug before I start taking it, I never like walking blind into anything but goodness seeing all the negatives and the this is poison comments makes me wonder why I stop here so I decided to post for all of those like me who may stop by just because they are interested in what others think. First off stopping any medication without doctor approval is very dangerous especially when it's something that is dealing with your hormones! If something doesn't make you feel right you should talk to your doctor alot of times our minds play tricks on us and convince us that it's the medications we take that are causing the side effects when 9 times out of 10 it sounds like anxiety and not the drugs from all I've read. I personally think Synthroid is wonderful of course this is only the beginning of my 3 week of taking it but I feel better than I have in years!!! I actually have energy to do things, the soreness and stiffness I alway F 33 2 weeks
