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  Complete Thyroidectomy - cancer depressed, mood swings, full of rage at drop of a hat and even feeling suicidal more and more, muscle cramps, no energy, tired, foggy head, weight gain, I even got diagnosed Bi-Polar! I HATE what I have become! I never even thought about Synthroid being the culpret to all the craziness in my life. But after finding this sight it all makes sense. I have a herbalist friend that mentioned all natural alternative that could be prescribed. I am going to go ask her about it. I WANT MY LIFE BACK! I am tired of feeling guilty on how I see the world and treat those I love! I am tired of seeing the hurt in my husband and girl's eyes. I want to be me again... F 35 6 years

 1  hypothyroid - high TSH Insomnia, chest tightness, headaches, high blood pressure, tiredness I tried this drug 4 times over 4 years. I could only stay on it for a few months each time before deciding I was better off without it despite my doctor's advice. When I stopped eating bread and began eating natural fat (as opposed to low fat dairy) and meat, eggs and fish in moderation with lots of green veg my TSH improved from 53 to 6.6 and my T4 went from 8 to 11.4.I made the changes to my diet after reading material published by Barry Groves.(Website- "second opinions" and 2 of his books.)I am grateful to the people who have contributed here in the past.

 3  Total Thyroidectomy Tired, overwheming emotional detachment, moody and lack of patience. I'm already on a higher dosage @200 for 6 months now (started 125), and I still feel tired and not myself. My levels they keep telling me are in a good range leaning towards high. I've always had a slower metabolism so this seems contradicting to me. I feel sad for no reason too often. F 30 1 years

 3  Born without a thyroid So, as I was born without a thyroid, I've been taking synthroid my whole life, and after reading these comments, I'm beginning to realize the reason I feel so depressed/crazy/"foggy" is because of this drug. I always thought, maybe it's just me, or it's normal to feel this way, because I've always felt it. Gosh, I am so relieved to know that it's the drug! maybe I should try another drug.... 21 21 years

 3  Yes Racing Heartbeat, chest pain, increased tolerance to generic synthroid (levothyroxin), decreased natural release of hormone by thyroid, joints aching I gained 80 lbs in 9 months after a collision and discovered my thyroid is slow. After beginning synthroid, I stopped gaining weight and felt better. 1 year ago, I was re-tested. My TSH is high, T4 low and T3 really low. My dosage of 50mcg was increased to 75mcg. My doctor said synthroid stops fooling the body over time and dosage must be increased. Also, synthroid doesn't replace T3. It turns out I have iodine deficiency - iodine helps your body change T4 to T3. I now take more iodine and feel better. My physical and TBI rehab began 6 months ago and my exercise level dramatically increased. I feel in my gut that as my body gets aligned and my exercise and diet improve back toward where they were before the collisions, the synthroid necessary for my health before now feels like a blockage toward my thyroid healing and producing the correct amounts of hormone on its own. Has anyone else had the sensation that it blocks production? I discovered that the horrible aches in my joints, especially in cold weather, can also be caused by synthroid (osteoarthritis). I stopped it two weeks ago and feel improvements in not aching as much and I lost 5 lbs. After reading these reviews, I definitely want to have my levels re-checked and to request Armour, which is said to help both T3 & T4. Has anyone improved their natural levels through diet and exercise? Can this be done? Also, has anyone noticed their symptoms started after a throat and/or head injury? F 44 4 years

 1  Hypothyroid Extreme fatigue, anxiety and panic, hypoglycemia, heart palpitations, racing heartbeat, irritabilty, brain fog, poor concentration, poor memory, chest pain, hair loss like you wouldn't believe, I had to end up cutting several inches. This drug was terrible for me, I had to quit taking it altogether, The side effects from Synthroid were worse than the actual hypothyroid itself before my dx. I was seeing a doctor who didn't seem to understand enough about the thyroid, so I finally saw a new doctor and he prescribed Armour, and it has made a world of difference! I feel much calmer and while my dose is still low and not optimal yet, I still feel so much better than I did, I have lost that awful brain fog too. I will never go back to Synthroid, if it were the only drug out there for this, it's worse than being hypo. That is my experience, Oh yeah, my doctor said Synthroid is no good, and that I need the T3. F 39 2 years

 3  Congenital Hypothyroid Fatigue, acne, achy joints, dry hair....those are about my only complaints. Otherwise, it did its job. Kept my levels normal until I became resistant to the hormone. Had to add Cytomel into the mix. Didn't alleviate the symptoms so I switched to dessicated thyroid. Much better now. I read a comment that said something along the lines of "weight gain be damned, I will not use Synthroid"....Is that some kind of joke? That hypothyroid just causes weight gain and it's not big deal? Unbelievable. It's important to stay on your hormone replacement. If it doesn't work, stay on it until you find a suitable replacement. Seeing as I was born with this, it isn't something I take lightly. Some people are so ignorant. Also, Synthroid sponsors doctors people! That's why it's still being prescribed. And since when did the FDA give a flying f*ck? Accutane is practically black boxed and yet it is still being prescribed for even mild acne. Anyways, if Synthroid isn't working out, then ask your doctor/endo about dessicated thyroid. Although, I can guarantee yourself the fight of your life trying to get the prescription. I sure as hell had one. F 20 18 years

 2  Graves iodine trtmnt, now low th Severe depression, weight loss, heart palpitations, mood swings, loss of appetite, goiter! Hair loss, and mixed sleep patterns After the iodine treatment, they put me on synthroid. It helped after three months and although I had prickly skin feelings, and mood swings, they started me on Xanax. Not good! Waves of depression hit me and only after I go down from synthroid, the anxiety goes away and the depression lessens. When I discuss this with my doctors, they said I was bi-polar. For all these years, I can not gain weight. I am 5' 9 and weigh 115! I am now on klonopin and synthroid. My neck feels like I have a goiter. I am anxious and in a deep depression. When I cut back on synthroid, things feel better. Makes me wonder if I need it at all? F 60 25 years

 1  hypothyroidism extreme hair loss, including greatly thinning eyelashes and eyebrows; heart palpitations and heavy feeling in chest sometimes at night; blurred vision and dry eyes; join pain is much worse than before taking med; weight gain and inability to lose weight even when working out very hard; can't stay asleep at night; sometimes have extreme anger and agitation that I hide from everyone because that's not who I used to be. I thought I was losing my mind until I found this website and read the comments. One night I honestly thought I was having a heart attack because my heart and chest felt so strange. The hair loss grieves me very much, because I doubt it will ever grow back. It's been extreme since taking Synthroid. I was going to the gym five days a week, watching what I ate pretty carefully, and in five solid months of working out all the time, could not lose one single pound. Now, my weight is creeping up, even though I'm working out a lot. I think I'm going to stop taking it NOW and go see a homeopathic doctor for alternative treatment. This makes me angry to read what is happening to so many people at the hands of doctors and the powerful pharmaceutical companies. Interesting that we all experience similar things, and yet the doctors keep telling us this stuff will HELP US. No, God help us all in fighting for out rights to become healthy. F 57 90 days

 2  Autoimmune thyroiditin (Hashimotos) Burning in throat, ears ringing, no weight loss, This medication makes me feel like I'm on a roller coaster, every day is an up or down day. I don't like the fact that there is no consistency to this medication. It has helped slow the hair loss and make me less fatigued but symptoms are still present. I have yet to lose weight even with proper nutrition and exercise. F 35 1 years

 1  Hashimoto's MAJOR Brain fog/ feeling drugged, low blood pressure, low blood sugar, headaches, occasional diarrhea,muscle weakness and major fatigue, low memory. When on 75 mcg I would have heart palpations, insomnia but tired, major diarrhea in the morning, and anxious. Have lots of bad days on this medicine. I know its the synthroid bc i was not feeling "drugged" before i was on it. Have no choice. All the doctors say its not synthoid but I find it hard to believe all these people complain of this dizzy brain fog feeling. Endocrinologist dont know crap and dont want to help. I would be on a million prescriptions to treat all these symptoms but I'm not going to fall for this. This is all bc of synthroid... im way to young for this crap and want my life back! F 26 3 years

 2  Hypothyroid Was on the generic at first and I would vomit literally as soon as the pill hit my stomach and if I didn't vomit I would have really bad gas and or diarrhea. I was switched to half the lowest dose of the brand and this still gave me gas but didn't make me vomit. My dose was upped yesterday and after taking the medication as prescribed I had severe gas pain cramps and diarrhea. I work with food and this has kept me from being able to go to work now F 25 6 weeks

 1  hashimoto's Slow introduction starting w/12.5 to 25. No change in tiredness or sleeping symptoms, but hair loss slowed. Drug conflicted with theophylline and caused allergic asthma mild attacks. Increase in nausea, nightmares, itchies, brain fog and other symptoms. Had to take it at night with small amount of food in stomach which conflicts with instructions. So in general - not a good match. Too much filler - hard to figure out what is causing drug interactions. F 60 2 months

 4  hashimoto's None as long as I don't take too high a dosage. If you are having depression and brain fog, try cutting out gluten. After years of depression and a more recent bout of brain fog and fatigue, I eliminated gluten from my diet and felt much better. I also lost 10 pounds. Also, my dosage of levothyroxin has changed over the years. I do better when I take the lowest dosage which keeps my thyroid in an acceptable range. F 63 35 years

 2  tot. thyroidectomy/papillary cancer major fatigue, irritable, loss of appetite, loss of taste, and nose bleeds. Had my surgery on November 12th and the radioactive iodine on December 3rd. I understand that it should take awhile for this medication to balance out, but I would think that I should feel some sort of difference. I am still sleeping about 12 to 14 hours a day. I wake at 6am, want to take a nap at 2pm and am back in bed at 6:30 or 7pm. Not sure if the nose bleeds are residual side effects from the radioactive iodine, can't find any infomation about that.
