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  Hypothyroidism Anxiety (not panic), irritability w/o any cause, tremors, hair falling out, thinning eyelashes, blurred vision, tearing (dry) eyes, lump in throat, insomnia, unexplained weight loss/gain, tinnitus, itching ears, palpitations (>100 bpm), low body temp, intolerance to cold, spacey, tired, trouble talking (forming words/sentences), very active brain/thoughts (wouldn't shut down) Some of these symptoms are part of the disease.. but some resolved when I discountinued Synthroid. The mood issues, ear-issues,blurred vision and palpitations went away when I discountinued Synthroid. Now I sleep great and can drive again! These issues came back when I gave Synthroid a second chance (I thought maybe I was mistaken the first go-round). Also, just to be sure, I consulted with a professional/licensed therapist who confirmed that I was mentally healthy and didn't need therapy or mood-altering meds. I would sooner remain hypothyroid than take synthroid ever again. The Synthroid side effects were far, far worse than the hypothyroid symptoms were to tolerate. F 43 12 years

 3  Total Thyroidectomy irritability, dry mouth, emotional I had a TT in May '08. Was on 150 mcg for many months and suffered weight gain, etc. Doctor switched me to 175 mcg. and now I have been able to lose a few pounds, but I feel irritable and have a dry mouth. Is my dosage too much? 150 didn't seem like enough. I don't know what to do? F 47 2 months

 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

 1   I gain 32 pounds in the first 3 months each time the mgs are increased I gain weight. Almost everything I read on the drug it is quoted this is not true. Walk in the patience shoes of the ones of us who this has effected in this way and you will not say that. Many of us are effected by weight gain and no professional wants to take responsibility for the ones of us who HATE this side effect. F 55 5 years

 1  Levothyroxine Sodium hypothyroid I think this drug has affected my life negatively for 7 years. I have had extreme anxiety & depression, insomnia, joint & muscle pain, migraines, headaches, hearing loss, tinnitus, dizziness, neck pain, eye pain & bulging, possible TMJ, bone loss (in teeth), carpal tunnel syndrome, memory issues & brain fogginess, shortness of breath, difficulty waking in the morning, irritability, & PMDD. I take a generic - it just says "levothyroxin" on the label. I just discovered my symptoms seem to be linked to the medication. I have been to countless doctors of several specializations - and what bothers me is that not one of them linked my symptoms to the levothyroxin. I have been off it for about 72 hours and already my anxiety is almost diminished and my pain is reduced. You have to be your own advocate. From what I can see, there are numerous types of hypothyroid issues & treatments, and I plan to do my own research now. Don't rely on your doctor 100%. F 34 7 years

 1  hypothyroidism It was the most horrible experience of my life. Water retention, hives-even in my mouth, boils, weight gain, depression, anxiety, heart beating so hard I could feel it hitting my hand when I put my hand to my chest, I was almost to the point of being suicidal, I'd cry at the drop of a hat, eyes bugging out, unable to focus to read.

 1  Hashimoto's Hypothyroid Can't lose a SINGLE pound!..Feeling More awake I was diagnosed with hashimoto's a year after my daughter was born. I thought it would be great to get on thyroid medicine and have a pill help me lose weight...no no! Since then, I have been counting calories (1300/day) and doing the Insanity beach body workout 6 days a week and have not lost one pound! (haven't gained either..but still!) This is ridiculous! I thought I was crazy when I would forget my pills for a few days and start to lose a few pounds. Then I surfed the web and saw how many people have GAINED weight! So, I decided to go off the levythyroxine until I lose 20 lbs and then I'll go back on it and maintain that weight! I did one last blood test today and haven't told my GP about my plan...but in another 3 months, I'll ask my endo to either try the brand name or the armour. I'm just bummed this will be my life-long struggle...argh F 37 3 months

 3  hypothyroid Very dry/red (inflamed) areas on eye lids and skin under eyes. I was absolutely miserable. People would stare at my face all the time wondering what was wrong with me. Lived with this condition for two years. No matter what I tried, it would not go away. Not only was I experiencing this, but my eyes got so dry soon after. It got so bad that I went to an ophthalmologist and he told me I had Chronic Dry Eye Symptom. I was prescribed Restassis for this condition which I was going to probably have to be on for the rest of my life. At this point, I am just so annoyed with all these weird things that are happening to my body. I've always been such a healthy person. To make a long story short, I am ready to go on vacation and I have a million things to do before leaving. I forget to take my Synthroid medicine on Thursday, and on Friday, the whole inflamed mess around my eyes is just about gone. First time in two years my face/eye area looks normal. My husband asked me what I did diff I take 75 MG Synthroid a day but have to take 1 1/2 50MG to equal 75MG. F 59 3 years

 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

 1  Hashimotos I had horrific reactions to this drug and unfortunately it unrecognisable and was a slow process. At first the Dr's blamed my symptoms on perimenopuasal, then menopause. I became suicidal severly depressed...my children wont speak to me for 2 years now and I'm a grandmother, I havent seen my grandchild who was born last year. My kids kept saying they felt like walking on eggshells around me and I was very negative. I stoped taking it over a month ago and I feel so good I simply cant believe it, it's incredable. I would rather be dead than go back on that medication Synthroid stole my life for 13 years and I have no family as a result. If you are on this drug and intolerant, irritable, anxious, nervous, worry, cant sleep, dark thoughts and negative...simply STOP IT take Armour or thyrolar M 52 13 years

 3  Hypothyroidism None that I know. My doctor said I had hypothyroidism and she prescribed the Synthroid. She said I was going to feel much better, not tired and would be able to lose weight more easily. I hadn't felt bad at all before the Synthroid and I haven't felt any "better" now. I feel exactly the same. I keep taking the medication just because my doctor tells me to, but there's no difference whatsoever. F 62

 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.

 3  thyroidectomy/thyroid cancer might not be due to synthroid itself, but more to just being without a thyroid and maybe no pill can make up for that. Dosage is "correct" according to lab results but still very tired most of the time,---i can't begin to tell you how tired---i could spend days on the couch sleeping or hybernating-- weight gain, constipation, sinus issues, feel run down, on Effexor for depression, anxiety, heart palpitations at times and blood pressure shoots up so am on Toprol xr for that, sweat easily and alot but could be from the effexor too, and can't tolerate heat... Achey alot of the time also....sometimes weird tingling in my fingers, feel like in a fog sometimes mentally. Would be an emotional mess if not on effexor. F 45 20 years

 1  Hashimotos\Graves? swollen face, swollen nipples, fluid retention, mood swings, depression, brain fog, extreme oil production in face and scalp, excessive sweating, excessive body heat, blurred vision, joint pains, swollen eyes (graves..or Synthroid?), fatigue, weakness, delayed brain reaction, insomnia, difficulty waking from sleep, frequent urination, occasion frequent bowel movement, weight gain I have been been on this drug for almost 3 years. I felt great after having thyroid desiccated for 4 weeks. After that my life has been hell. Being on this drug I have had every side effect from brain fog to memory loss to fatigue to blurred vision. In the last few months it has become so bad I am at risk losing my job because I can no longer concentrate while driving because I get dizzy spells and cannot focus mentally and optically. I have been to 4 docs, 2 of which have been endos and they have not even mentioned Armour, not the least bit concerned with my symptoms. I have a wife and a daughter that I must support and through recent research my wife and I have concluded that the best path may be to visit a homeopath. If you are considering taking this drug (synthroid) DO NOT!!! Most doctors do not even acknowledge the Amour brand because they stopped teaching its use in 1975!!!! This Synthroid is garbage and the doctors and the Knoll Company are making profits every single time someone has issues with their thyroid. People are losing years and their livelihood while some jackass is laughing to the bank. Modern medicine can be a wonderful thing, but the major pharmaceutical companies are willing to jeopardize lives and path their way to hell to make us forget the ways of the wise and cash in on our misfortunes. I want to beleive in the Amour. From everything I have read this shift towards alternative medicine makes sense. I will update with the Armour results. M 35 2.7 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
