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  Hashimotos extreme fatigue, reduced bowel movements (once a week), change in appetite, headaches, dizziness, confusion, morning sickness, changes in menstral cycles, pain in joints and muscles. Ive been taking synthroid for four years and it's had its ups and downs. My doses change every six months, and Ive not been able to find stability in the drug. I sleep A LOT, more than I should. It is difficult for me to work for eight hours without sleeping. After work, I go home and fall asleep for two hours every day, wake up and eat dinner, and go back to sleep. On days off, I take three or four naps a day. It's incredibly frustrating because i can't stay awake even if I have things to do. The headaches are also terrible. I experienced severe joint pains and muscle weakness, and began taking a vitamin D supplement, and that helps a bit. I'm simply frustrated with the inconsistancy and fatigue. I'm sick and tired of being sick and tired! F 19 4 years

 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  Hypothyroid I feel fatigue some days and other days I feel great, Insomnia, weight loss (which I am not compaining), I have to make myself eat and my toes are always cold, which affects my balance. Because of my balance problem, I have fallen 3 times, all on staircases. I make myself aware in public places when I have to climb stairs and hope that there is a rail I can use. Synthroid releaved my joint and muscle pain which had become severe in my shoulders, arms and hands. F 47 1 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

 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

 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  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

 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.

 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

 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

 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

 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

 3  Hasimotos Anxiety, depression, paranoia. I was diagnosed with Hashimoto Thyroiditis 13 years ago. I started out taking 50 mg Synthroid and then moved up to 75 mg. Four years ago a surgeon almost talked me into having my thyroid removed because of the enlargement of my neck. I thank God every day that I decided not to have it removed and I went for a second opinion. I didn't need my thyroid out. My regular physician then increased my dosage to 100 mg and I have been experiencing terrible side effects ever since. I had also taken singulair for a brief time and thought I was going to commit suicide. It was the most horrible medicine I have ever taken! For the last four years I have been looking for something to help my thyroid. I am now on my way. My chiropractor started Nutrition Response Testing in his office. It's the best thing I have ever done. I have been taking Thytrophin PMG and Prolamine Iodine for my thyroid and it is working to strengthen it naturally. I had my bloodwork done this week and my PCP called me today to decrease my synthroid to 50 mg. My goiter is going down. I don't remember having these side effects from the synthroid when I started out at the 50 mg so I researched to find the ingredients in the different synthroids. The 50 mg has no color additives nor does it contain any Aluminum Lake. The other one's all do. This might be the ingredient that causes so many terrible side effects. I have learned from research over the last 4 years that artificial sweetners, colors, preservat F 33 13 years
