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  Hashimotos Daily uterine cramping, 60 lb weight gain, exhaustion, extreme mood swings, body odor, depression, suicidal thoughts, night sweats, hip pain, & insomnia. 95% worse on meds than I was with 46 tsh. Symptoms stopped 1 week after stopping synthroid. Currently taking Nature Thyroid. Much better except daily cramps & night sweats are still present. Can't find dr who will make any effort to figure this out. Wondering if the meds are elevating my estrogen levels. Trying to conceive for 2.5 years. F 36 6 months

 1  Hypothyroidism Caused irritability, anger and depression. I never felt well while on this medication. I went back on Levoxyl (50 mcg.) and felt much better. The only reason I was originally prescribed this is because Levoxyl was temporarily taken off of the market. Once Levoxyl came back on the market, I switched back to it and felt MUCH better.

 4  Hyperthyroidism I didn't have side effects. I was originally taking the generic form. Recently my doctor switched me over to synthroid. The only thing that has been noticeable is dry skin, and sinuses will not drain. Not sure if it is contributed or not. I have had this condition for several years. I am active, have not experienced hair loss. I am getting fatter but I will contribute that to my age and the delicious beers they are crafting these days! HA! M 46 26 years

 4  Hypothyroidism I have been on Synthroid for well over 13 years. It's a good product if you know how to take it. I've read many articles and books on the subject. I've tried generic and will not do that again, it is not as effective. I've tried it with a lower dose accompanied with Cytomel and that was too much for me. I've tried natural thyroid ( Armour Thyroid) and that just about gave me a heart attack. It took several years to get the dosage right and it never has seemed perfect. I sweat constantly and I have tsh levels that are teetering on hyperthyroid instead of hypothyroidism, so in the summer months my dosage has to be lowered and in the winter it goes back to normal. I have a crazy appetite on it,yet if I go one day without it i have major bouts of crying and anxiety. I'm obviuosly hooked for life. My teeth have one by one been replaced with crowns due to calcium/bone loss, maybe due to this med?!I have a super tough time losing weight and never had that problem until I got on this med. I'm always hot or too cold. I get the worst pms and sometimes debilitating headaches but only if my body is saying that I'm getting too much. Listien to your body and not lab tests. It's overall a good drug though and better than the alternative. I have perfect blood pressure. Perfect blood work. I sleep good. I'm 38 with little long thick hair and long nails ( all signs of a healthy body) good vision. I sometimes can't think good and I do have attention issues. Sometimes my chest hurts with exerti I recommend it but talk to your doc about adding Cytomel or adjusting dosages. I also recommend taking selenium and zinc to help aid in function. But check with doc first. F 38 10 years

 1  yes Complete hypothyroidism Don't bee fooled people. It is the fda that is responsible for the thyroid hormone to be taken out. What morons with to much power. We need 90 to 110 percent potency put back in our pills a d then we will all feel good again.fight! Fight the fda! Demand it back.they think we don't know.what a @ joke! They don't know based a a group of people with an elevated heart beat.they were probably going through menapause. Stupid fda took a group and made a ,very bad desicion for the rest of us! I say this lets have drug companies make 2 types of thyroid drugs. 1 that is 95%to 105% for the group that needs them like that and make very potent 90% to 110% back for us that need it back! Let's write our congress men and fight this enemy fda. Take to supreme court press charges for the seriouse illnesses they are causing us! I'm very seriouse. These dummies aren't listening to patients suffering at their hands. F 30 1 days

 3  TOTAL thyroidectomy Hair loss, moodiness, sleeping too much, sleeping too little, racing thoughts, pain in hands, knees, ankles, irritated my inflammatory response, acne, anger, mood swings I had a total thyroidectomy on february 20. I was put on synthroid at 88mg. One month later i had my tsh levels tested and was 25tsh. They upped my dose in april to 112 and my tsh went to 12.5. Then in june they upped it to 150mg and now my tsh is at .4. This is to suppress the cancer cells in the papillary cancer which was removed. I still have medullary thyroid cancer cells in my neck, left over from the surgery. Please tell me this gets better. F 41 5 months

 2  Hemithyroidectomy Went from 100mcg to 88mcg to 75mcg following hemithyroidectomy. At times cannot sit still/hands will jitter/weakness in legs like there are weights in them. Also weakness in arms. At times brain fog and cannot concentrate. Always feel heart pounding in chest and anxiety has worsened. Have temperature intolerances and will sweat when not even that hot. Racing thoughts that keep up at night. Within the span of 1.5 months tsh went from 1.1 to 2.4 then back down to .8 on the same dose. Attempting to get a lowered dose (because I still have half a thyroid...but I'm in the low "norm") F 20 5 months

 1  Hypo Rapid weight gain, significant hair loss, brain fog, sleepy all the time, severe irritability, unexplained anger, increase in depression. My endo switched me from cytomel to synthroid. Disaster! First couple weeks weren't too bad although the fatigue and hair loss began. Week 3 was awful. I stuck with it as it takes a few weeks to see the benefits. I eventually stopped the medication due to severe mood changes and I did not notice any benefit. Switched back to cytomel at higher dose and feel fabulous! F 51 3 months

 5  Hypothyroid I didn't experience any side effects when using a therapeutic dosage. However, if you're taking too much, it soon becomes apparent because you begin experiencing the symptoms of hyperthyroidism. For me this drug has been successful in treating my hypothyroidism. It may also be beneficial in preventing migraines, if the headaches are associated with hypothyroidism. The drug even seems to help my overall mood as well. Lastly, it seems to help my insomnia quite a bit. F 38 10 years

 2  Pregnancy preparation Hair loss, dysfagia (difficulties to swallow), lump in my throat, sleep apnea (very hard-stopped to breath),anxiety, depression, panic attacks I began taking Synthroid from 12 mkg, first three days I felt lump in my throat, but doctor said it was just stress(?). After I felt well, same on dose 25 mkg. But after 1 month since I increased my dose of Synthroid till 37, I faced all bad things which I wrote in the column near. Its began from terrible hair loss and finished with terrible apnea, anxiety and panic attacks. Worst thing is apnea, anytime I begin to sleep I don't have enough air, so I basically don't sleep now just few hours in the morning. The really worst thing that no doctor would connect these symptoms to Synthroid, so even me I began to believe that its ok. But the symptoms are still there and are worse now. Thanks God I met one doctor who said first thing to do is to stop Synthroid, if after 10-12 days symptoms are gone than its side effects, if no, search another reason. In case if I still require Synthroid to try another brand because the same medicament can affect people different. Some people can tolerate it normally, some people would have side effects.Already for this advice I am very thankful to doctor and hope it will help somebody. F 29 6 months
