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)

 1  underperforming thyroid inability to lose weight despite very restrictive diet. Dry skin, eyebrows disappearing, continuing fatigue, continuing brain fog. It never did anything to resolve my many hypothyriod symptoms. I felt awful on it and hate it passionately. It does nothing but offer a false hope. Armour thyroid, on the other hand, offers a true hope to thyroid patients. It sure did to me, after years of nasty synthetics! F 55 25 years

 1  graves disease deep depression, hair loss, broken nails, loss of libido, sweating-ruined clothes and sheets I was extremely upset to read Dr Arem's book and found out there is such a drug called antithyroid which I could have been treated with except that the medical profession had deemed I was too old(49-the cut off was 45) even though my primary dr thought I was much younger because before this I was in excellent health!I was taking synthroid for 14 years and began experiencing the old side effects it was supposed to treat. I gradually went off it and began taking herbal supplement and vitamin replacement. I am no longer depressed but still have achey joints.. I went to my local health food store and talked to the owner who said he began his business because his wife had the disease also. She is now on a low dose of zoloft. My husband took that for 10 years. It made him think he was better but I and our children were terrified of him. When he got cancer we went on a completely vegetarian diet and he was able to go off it and became a completely different person. Also I lost 22 pound F 14 years

 1  Hypothyroidism Breast Cancer Within my start of taking Levothyroxin I noticed a lump on my right breast. Two months later I have an invasive lymphocarcinoma diagnosis. NO family breast cancer history, no previous cancer at all - but it had spread into my lymph nodes within a two month period. DO NOT TAKE THIS DRUG. Research on the internet has shown links between synthroid and breast cancer, but it is not listed on the side effects as it has not been "officially" proven. Stay away from this drug. F 45 2 months

 1  My Thyroid was removed Cannot lose weight, tired, achy bones, mood swings, intolerable to heat, emotional, emotional, emotional, hair loss, dry skin, sometimes could sleep for a day straight just get up to go to the bathroom, constant sinus infections etc... I had my thyroid removed when I was 21 and have been on thyroid ever since. I seem to gain a few more pounds a year and my symptoms get worse. My blood levels are fine and my doctor looks at me as if I am going crazy and need anti-depressants, why do they resort to anti-depressants instead of figuring out what the problem is? I have been considering stopping my 150 mcg daily dosage. I did the master cleanse for 10 days and didn't take my synthroid, I have never felt better. Has anyone out there stopped taking their medication and tried to replace it with natural boosters and/or iodine? I can't take the side effects and can't seem to get any help from my doctor. Sometimes I wonder if they are controlled by the makers of these medications. My calcium levels have also lowered. I am 31 and shouldn't feel like this. I feel like I have been robbed of my prime years. My husband must get tired of my constant complaining. I don't even have the strength that I should have. I can't e F 31 10 years

I had my thyroid removed 10 yrs ago due to multinodules. I was put on Synthroid & immediatly gained 20lbs and felt horrible. Felt worse after giving birth to my son.My dr kept telling me that my blood levels are fine. Yet I still feel tired, I could sleep for a day and miss work, my bones ache.I feel like my 20's came and went and now in my 30's I refuse to let more time go by.I am losing my hair in sperts.I thought that it was just my blood levels, and she played with my dosage not helping. Now that I am researching I really feel it's the Synthroid. I did the master cleanse and stopped taking everything for 10 days. I had never felt better, but I still need to be on something because I do not have a thyroid. I've talked with my dr. and she insits I be put on anti depressants. I am not depressed but will be if they can't seem to stop masking the problems with more meds and start finding out what is wrong with me. I just went in on Fri. with all my vitamins, research I've done, qu F 31 10 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

 1  Hypothyroid WEIGHT GAIN -- I have gained a CRAZY amount of weight in the last 3 months without any change in my diet or exercise program. I told my doctor that I have gained more weight on this drug than when I was pregnant with my children! Also, a TON of hair loss .... Hate it, hate it, hate it .... there has to be something else. I am on 100mcg currently ... down from 15omcg because that was WAY too much for my body to handle and the side effects are evil. F 39 4 months

 1  Hypothyroid Excessive weight gain on hips, buttocks and abdomen, swollen breasts, bloating, joint pain/swelling, acne breakouts on forehead and neck, constipation, loss of hair I was considered subclinical hypothyroid and an Endocrinologist prescribed this drug (25mcg). I have gained an excessive amount of weight on it while continuing to exercise 6 days a week and eat healthy. My stomach makes me look pregnant, it has gotten so big and bloated. I used to weigh 133 lbs and am well over 150 now. The joint pain is awful (I am barely able to make it through a workout). I used to have clear skin and now have acne breakouts and have just started to lose my hair in significant amounts. All after just six weeks on this stuff. Do your research before starting this drug. I learned I could not tolerate this stuff the hard way. I was willing to believe everything the Endocrinologist said about this medicine making me feel better. I refuse to take it any longer and am off it for good. Will try a naturopathic doctor who is willing to prescribe Armour or Nature-throid. F 40 6 weeks

 1  Hypothyroidism and infertility Too many to name but I will say I felt like I was dying when I was on the generic brand Levo. I gained so much weight in 4 months and felt absolutely horrible. I went to a special infertility hospital in Pittsburgh and they didn't help me at all. All they cared about was putting me on stupid Levo. I took myself off of this medicine and I felt so much better getting this poison drug out of my body after 1 day. I wasn't mean and crazy anymore as my husband said I was while taking the Levo. I have been on Armour and don't have any side affects. I am starting on Cytomel tomorrow because I am not getting pregnant yet and have been trying for 4 years. My medical dr. who is a real MD but doens't believe in drugs has just learned from a conference that women who are taking some Cytomel with Armour are getting better results and losing weight more and are getting pregnant. I am looking forward to trying this and seeing if I can get pregnant now. I have struggled with so many dr's who NEVER, NEVER TAKE THIS DRUG. YOU WILL REGRET IT!! MY MD SAID IT WILL MESS UP YOUR THYROID EVEN MORE. F 37 4 months

 1  hypothyroid disease headaches, weight gain, mood swings after reading all the reports and thinking I was the only one experiencing these side effects, I now realize it was the medication. I was on weight watchers thinking it would help me loose weight and I gained. Fact is I was eating more food on weight watchers than I did on a daily bases. Synthroid has made me gain weight at a rapid pace! I am a laid back person and I could snap at any time at anyone for no reason. F 44 3 years

 1  cusp hypothyroidism Weight Gain, Bloating, Painfully cracked lips, chest pressure I have been on the cusp of hypothyroidism for years and have fought taking medication. Since going through early menopause, I had trouble losing weight, even with exercise. I gave in to taking medication after my newest Dr. told me it was "beneficial". After taking Synthroid for a couple of months I told my Dr. about my weight gain and she raised to 50 mg to speed up metabolism. I have not lost the weight and feel bloating. I also told her about my cracked lips and she offered to refer me to a Dermatologist because she never heard of this drug having this side effect. She told me that my body needs to get used to the drug. I want to stop taking it and take a homeopathic approach. I am sorry I ever gave in. F 42 3 months

 1  hypothyroidism disorientation, joint pain, uncontrollable and unpredictable mood swings, swelling of hands and ankles, headaches, tiredness ALL the time. Another reviewer called this a suicide drug and I agree completely. I am having terrible bouts of anger and crying for no reason and I can't seem to get it under control. It is affecting my job performance as I can't concentrate and at times I have become irate with my coworkers. There is no warning for when this is about to happen. Without this drug I am a very laid back person, on it I have become a lunatic. I seriously was afraid I was going insane until I read the side effects. I am going to demand my doctor find another solution to my thyroid problem. I can't go on like this. F 54 90 days

 1  Hypothyroid Was fine on synthroid 50 mcg Endo increased it to additional 100 mcg on weekends Three months subsequent to increase gradual emergence of myriad symptoms Felt extremely sick ,palpitations that were audible nocturnally Change in BM patterns , muscle weakness and general fatigue ,blurred vision . Hand tremors ,body shaking from inside . Both GP and endo dismissive and extremely condescending .was incredulous at the decline over such a short period , didn't know how to proceed because it was obvious that sone doctors are extremely rigid and do not have the capacity to deal with idiosyncratic deviations Both insisted that blood levels were fine and emphatically indicated that I should continue in synthroid I was convinced it was synthroid because I noticed anecdotally that a couple of hours after taking it The feeling of not being well would emerge Stopped taking the extra dose and then stopped taking the regular med but resumed out of fear that prolonged cessation would put me into hypothyroid state Have an appointment D t with another endo F 64 0 years
50 mcg 1X day
