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)

 3  Total Thyroidectomy and Cancer Fatigue and insomina, some nausea, irritability, anxiety and depression, very emotional, crying alot. I think I am still working on finding the right dose. The jury is still out as to whether I will stay on synthroid or switch to Armour, or something else. I am trying to be patient at least for another 45 days to see how I feel on 125, otherwise may increase my dose. I would rather deal with the insomnia, than the depression and weight gain. But, I am happy that my thyroid is out and the cancer is gone! F 33 50 days

 1  hypothyroid Extreme memory loss; feeling of dissociation; tingling in extremities; extreme anxiety; insomnia; neck stiffness; lump in throat feeling; fogginess in head; loss of coordination; trouble finding words; tremors; extreme blood loss during menstruation; hallucinating, mainly auditory; fast heartbeat I thought I was losing my mind, feeling like my limbs weren't my own, hearing things, sounds being too loud (even silence feeling loud!!!) Panic stricken. Dizziness. Loss of coordination, and pcp thought it was an aneurysm from symptoms. Family terrified after hearing me talk, thinking I was having a stroke. I thought I was going to die. Husband told me he would call ambulance if I didn't go in for cat scan. This has been the most terrifying medication experience of my life. Different for different people, but how in the world could I ever recommend it to anyone. Terrifying, and it's still not out of my system. Still waiting for symptoms to clear and haven't taken't it since Saturday night (it's Tuesday). Still tremoring, stumbling on words, stiffness in neck. Memory's getting better, feeling less crazy. Still swollen hands and feet, and tingling in both. I would say stay away from this medication, as it feels poisonous to me, but I know it affects us differently. Most horrible drug on planet in my eyes. F 40 5 days

 3  hypothyroid I have been on Synthroid for the last 9 years but still continue to experience these problems, weight gain, loss of hair (I used to have lost of hair before, very thick) bloating, hunger, fatigue and lack of energy, skipped heart beat, palpitation, joint pain, muscle cramps etc. My doctor is refusing to believe it could be due to the side effects of synthroid and has diagnosed me with fibromyalgia and tells me it's all in the head. I am tired of feeling this way, not energetic and tired all the time. Now this irregular heart beat is concerning me. About four years ago I was put on a monitor to check the heart beat for 24 hrs but everything came out alright. I am on Synthroid .075 mg one day and alternate day .05mg to regulate the dose. The irritability and mood swings symptoms reduced after taking the medication. I sleep well at night, but feel very tired in the morning even after 7 hours of sleep. My constipation problem that I used to have before starting the medicine disappeared thankfully. I am concerned about my weight gain even on less calories and also my irregular heart beat.

 5  Hypothyroidism None This medicine is saving my life. I'm no longer tired, have no desire to stay in bed all day (this used to be the case), I'm able to get up and get moving without a struggle. Depression and moodiness are dramatically decreased, almost nonexistent. I swear I started feeling better after just a week of taking it, although many say it takes weeks, even months, to feel better. It kicked in for me pretty quickly and I'm happy with it. Zero side effects although I may have gained a couple pounds...however, I do NOT blame the medicine - I've been eating more junk than usual and I know if I cut back and get back to the gym it'll come off. The most important thing here is that I feel better, and I do. Maybe in the future there will be a need to incorporate T3 as well but for now I'm extremely happy on Synthroid. F 27 30 days

 4  Hashimotos Heart palpitations when dose raised to 150. It was returned to 137, much better. Also take cytomel, vitamin D for deficiency found. This combination plus taking synthroid 1 hour before eating is working. I have taken synthroid successfully 8 years and my mother is taking it for 28. Most people's comments are not about synthroid. Low thyroid people often have Vitamin D deficiency which is causing the joint pain. After I supplemented with D, the problems went away. Also I had stopped moving because it hurt, went to aquatic exercise and began again. Joints feel better when moved. Also supplement with calcium , triple strength fish oil, glucosamine chondrotin msm and multi vitamin. F 60 8 years

 2   brain fog, some weight gain, fatigue, ringing in ears, hair doesn't grow no matter what I do, dizziness (not sure if it's related to the ear, fertility issues?? (tried for 2 years and nothing) I've been on Synthroid for so many years and used to be skinny as a rail. Fast forwards 9 years...weight gain of about 10 pounds without changing diet (I really watch what I eat). I have this annoying ticking in my right ear...and am tired every single day (I've caught myself falling asleep at work). My numbers are all normal but feel like I felt much better not being on this drug. Has anyone switched medication and noticed an improvement? Or does anyone think that they reformulated Synthroid and some people are having adverse effects? F 33 9 years

 3  Hashimotos None I have just started taking it at bedtime on an empty stomach because my levels are so out of whack even though I faithfully took the med every morning 1 hour before breakfast. I presume it is due to dietary interference. I like fortified cereal, yogourt & tea - turns out iron and calcium can block Synthroid. F 48 14 years

 3  Hypothyroidism After taking medicine in the morning on an empty stomach, I noticed about 1 hour later symptoms of brain fog. When I reduced my dose below my recommended dose, I felt better. But, I can't continue with this since it will make me more hypothyroid. Does anybody have the problem of brain fog after taking their pill? Has anybody connected this with serotonin or low cortisol? Any help would be appreciated. M 43 15 years

 1  Hypothyroidism Muscle aches, stiffness, drowsiness, ankle swelling I took Synthroid for 6 months. Initially it helped but after three weeks I began to get stiff. If I sat down for more than ten minutes, I had to walk for 2 or three minutes before I could move normally. At a check-up after 1 month I told my doctor and he said I was out of shape. This didn't start until I got on the medicine. At my 4 month check-up I told him that my feet were beginning to swell, but he didn't see anything abnormal. Finally, after 6 months I found another doctor who put me on Armour Thyroid and all my symptoms went away! I feel like a new person. Ditch the synthroid and try Armour thyroid. M 48 6 months

 4  Hashimoto's thyroiditis Mild heart palpipations at night if lying on my left hand side. Nothing else. It took a year for me to actually start feeling better on this mediciation but it was worth the wait as now, 2 years in, I feel entirely normal again. Anyone who has suffered from an underactive thyroid will know the joy that just feeling 'normal' again brings! I'm delighted with the medication now and get tested every 6 months or so to see if an increase is necessary. M 24 2 years

 2  Hypo Major weight gain, brittle hair and nails. Always hungry. Ok I am really tired of being told it is in my head. My family Dr. put me on it in 2009 and said the levels were a bit low. ever since I have gained almost 30 pounds and nothing I have tried to do has helped. Called her a few months ago and told her my concerns and she told me to go on Weight Watchers. I also tried to get off of it and I got flu like symptoms (which I was told I was wrong about hat also). Finally went to an Internal Dr. yesterday and he said there was nothing wrong with me and said to go on a 1400 cal diet and work out 5 days a week. I asked him if I can get off the synthroid and he said yes and if I wanted they can check my levels in the future WTF? He is also the one that said it was in my head that I said I had side effects from trying to stop the synthroid. NOW I am confused. I have decided that I am just going to stop it and be sick, since I already feel like crap anyways. SO FRUSTRATED! Why won't anyone listen. F 36 1.5 years
