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)

 5  Hashimoto's thyroiditis None When first diagnosed, I had severe pain in my chest, dry skin, hair falling out and my emotional state could have been almost described as psychotic. My TSH was >200. I was put on Synthroid at age 26 and it's been a lifesaver. My hair and nails now grow at lightning speed, my skin is still slightly dry, but probably due to getting older. No joint pain and emotionally, I feel "normal" (lol) . I switched at one point to generic Levothyroxin, but it was not for me. It lent to instability of my levels so went back to Synthroid.

 5  Hashimoto's Disease No side effects that I am aware of. Before being diagnosed, I had heart palpitations pretty regularly, and although I still may get them sometimes, they're not as bad...and now I am aware that it is part of the disease. Before starting Synthroid, I was on Armour. Although I liked it, it eventually lead to rapid heart rate and high blood pressure. I stopped it and started Synthroid and it has been soooo much better. I don't bounce back and forth from hypothyroid to hyperthyroid as much, and if I am in a hyper state, it's not as bad. I just feel better now. F 31 8 weeks

 5  Dr. found nodules on thyroid None! Within 24 hrs. of starting brand Synthroid .50, I felt noticeably better. It took me 18 months and changing doctors 2 times (famiy and Endo) to finally find a dr. that would listen to my physical symptom. All the drs. knew I had thyroid nodules, but said my bloodwork was "normal". Even though I felt "abnormal", memory problems, difficulty concentrating, excessive dry skin, loss of libido, gained 15 lbs., course hair, hair falling out by the handful, brittle/cracked fingernails, extreme exhaustion after sleeping 8-9 hours...they said I was just "getting older" and maybe I need anti-depressents. I am glad I continued to persue this as if I would have gave up at the 1st doctor, I wouldn't be feeling so good today! I don't mind going every 6 weeks for bloodwork and exams on my nodules. So far, the nodules are not increasing in size! F 41 3 months

 5  Graves Disease I had no noticeable side effects to Synthroid. 10 years ago diagnose with Graves disease after a nurse realized my promenint Exothalamus (bulging eyee) I saw my first Endocrinologist I was prescribed heart medication and pre-synthroid regulators "tapazole" and then underwent radioactive therapy to reduce the gland. After which I was put on Synthroid. I stabalize immediately and over time my eyes reduced about half. Previous symptoms were constant hot flashes, fatigue, weight gain, mucles loss, low libedo...I was hyper...but due to the extreme hot flashes I was not interested in moving around much which lead to the weight gain. Its not bad to have to take it for the rest of your life, but maintain your blood test and if you gain or lose significant weight in your life time make sure to adjust dosage with your doctor. Synthroid doses is partly based on weght range. F 31 8 years

 5  hypothyroidism after radio I only had problem (rashes) after I switched to generic levothyroxine. I also noticed it's a lot harder to adjust dose of generic syntheroid. Once I switched back to the brand name I am fine. I have been on synthroid for 20 years and living an active life. I am thankful. F 51 20 years

 5  Hypothyroidism None The only problems I ever had was when my insurance insisted I switch to the generic form of Synthroid; it didn't work so I went back to the name brand. One of my daughters always kids me about my lack of memory and now I'm wondering if it's due to the Synthroid. F 41 18 years

 5  Hypothyroidism I experienced no severe side effects. Synthroid and Armour Thyroid helped me to lose 30 pounds within a year. I've felt a thousand times better--have much more energy, feel less depressed and anxious and have fewer cravings since taking synthroid. F 49 1 years

 5  hashimotos (hypo) no side effects I didn't have any symptoms; a routine test showed the numbers to be way off. Two comments 1)synthroid does NOT contain lactose, as some do. 2)don't eat for at least an hour after taking thyroid medicine (or few hours before) and take any mineral and vitamin pills at least 4 hours before or after the pill. Consult the Medline NIH website for any drug you take. nlm.nih.gov/medlineplus/druginfo/medmaster/a682461.html#special-dietary F 51 8 years

 5  Hypothyroid none! Changed my life! I thought I was dying before starting the synthroid! Now I wake up happy and feel normal for the first time in years! I look forward to the rest of my life now! I have been through hell before my diagnosis. 27 Drs and 60 lb weight gain to figure out that I had a thyroid problem. I hope this med never stops working! My results have been dramatic! It is like someone put the light switch back on! I have energy, I can think clearly,not cold anymore, no more fevers,sweats,anxiety,IBS,ringing in ears,anger, and depression that I had before starting this medication. If it is not working for you your dosage is too low. My symptoms got worse until my dosage was increased. I feel so normal now and happy! Thank god for my Dr and Synthroid! F 33 2 months

 5  Thyroid disease None This medicine is a first-rate quality product. Its consistency factor (important to those who really do have thyroid disease) is far superior to anything else. That’s why it trumps products made before its time and gets prescribed more than any other. Plus its lack of side-effects and return of stable lab numbers show why it’s the most recommended thyroid medication out there. If you’re newly diagnosed and your doctor has prescribed it – take it (as directed). If you’re already on it – stay on it. (And don’t be fooled by the disturbing internet marketing of second-rate so-called natural products - that involves the bashing of all synthetic medications and that is conducted by those who really should be seeking other types of help...) Stay safe and be well. F

 5   None. Unless you consider that it took care of hair loss and gave me energy again. I finally stopped feeling fatigued when I woke up in the mornings - the very first dosage I noticed the difference. I've found that you really do need to take it on an empty stomach - it makes a difference. I almost always wake up about 75 minutes before I really want to get up, so I take it then. I recently upped my dosage from 50 mcg to 75 mcg. I had noticed that my hair was again coming out more, and I had my yearly physical and blood test. Sure enough, my TSH was over the high end of 4.5 at 4.92. They recently changed the range and now anything over 4.5 means you need more. F 48 4 years

 5  hypothyroidism None Synthroid is a godsend. It cured me. It takes a few weeks to rebalance your biochemistry, so be patient. And it's very affordable. F 45 9 years

 5  I was born without a thryroid gland I am overweight and have difficulty losing weight. Most of the side effects are from not taking it like I should. If I get behind on taking my pills I get severe headaches and want to sleep all of the time. I have been on synthroid since several days after I was born when they realized that I did not have a thyroid gland. I always appreciated was the taste, because it tastes like candy. I also appreciate that with my insurance it is not extremely pricey since I have been warned by several doctors that the generics can be unstable. F 27 27 years

 5  hypothyroid - hashimotos Jittery feeling. The key to this drug is to slowly introduce it into your system. It has taken me a year to work up to 75mcg a day. I felt too jittery so started with 13.5mcg! After a month or so, worked up to 25mcg and then every other day 50mcg....By noon that feeling usually wears off but it made me short tempered. Also, this is one of those drugs where generic makes a huge difference, is not at all the same. I started with generic levothyroxine and felt as if I was in a fog most of the time. Switched to brand synthroid and that completely disappeared. This drug is absolutely necessary if your thyroid has quit functioning properly. I am no longer tired all the time, some minor hair loss stopped, skin feels better, less dry. I don't feel like I'm dragging around anymore even when I don't get enough sleep. The key is to give it time, do the dosage slowly. F 47 1 years

 5  Hashimotos Emotional swings, increased libido, mostly it has helped. I have been on synthroid for 13 years. It has helped me a lot! I stops my hair loss and fatique. I do however have trouble losing weight, high cholesterol even when diet is perfect, and recently they upped my level and now I am very irritable and you will all laugh, but my sex drive is off the charts! Husband does not complain about that! I will have to report it I guess. F 43 13 years
