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  Hypothyroid WEIGHT GAIN -- I have gained a CRAZY amount of weight in the last 3 months without any change in my diet or exercise program. I told my doctor that I have gained more weight on this drug than when I was pregnant with my children! Also, a TON of hair loss .... Hate it, hate it, hate it .... there has to be something else. I am on 100mcg currently ... down from 15omcg because that was WAY too much for my body to handle and the side effects are evil. F 39 4 months

 4  Hypothyroidism ?? I have been on it for most of my life, I was 14 when diagnosed . I take 300 mcg a day. have 4 normal kids..I am 38 now. Take your med EVERY day and in the morning before you eat.. all it does is replace thyroid hormone... The only problems are when you either don't have enough...or too much..which can be determined by a blood test. F 38 24 years

 5  hypothyroidism none I am very pleased with Synthroid. My DR had to initially increase my dosage twice, but once the right dosage for my body was found, my hypothyroid symptoms have diminished significantly.

 2  hypothyroidism The symptoms of hypothyroidism that I had initially (eg tiredness, carpal tunnel, tinnitis, heavy periods), went away but new symptoms, some consistant with hypothyroidism came in their place and got worse and worse....constant shaking both internally (like a buzzing feeling) and visibly externally, muscle weakness especially after exercise, necessity to eat every 2-3 hours to avoid feeling extremely unwell, joint pain, hair loss, brittle nails, abdominal pain I was told by doctors and specialists that the symptoms I was experiencing were NOT caused by the medication even though they started when I began the medication and have gone away now that I have come off it. I feel so much better. Symptoms of hypothyroidism have now started to come back so I will have to find an alternative. What? F 45 2 years

 5  Total thyroidectomy; Hashimoto's None, I feel very healthy :) I had a large goiter for years but before I had my thyroid removed, I experienced weight gain, approximatly 40 pounds, hair thinning, coarse hair, brittle nails, dry skin, irratability, depression, and severe fatigue and exhaustion. After my surgery, I was put on BRAND NAME SYNTHROID, and have felt better everyday, my weight is so much more easier to control, my hair grows, I now longer have dry brittle hair or bad skin. If your taking Synthroid, or the generic, and are having bad symtoms again, I suggest getting your TSH levels read again, and going to a couple different doctors, being thyroid patients we should all know that over the years of our problems we will have to deal with changing doses, so deal! I believe in removing problematic goiters and starting fresh with taking brand name Synthroid alone, I feel like the goiter may interact with how the medicine is absorbed/used in the body.

 1  Hypothyroidism severe fatigue, headache, cold all the time, constipation, weight gain, irritable, depressed, suicidal at times,severe joint pain, esp. at hands & feet, tinnitus and now hearing loss I am 53, female, and had a goiter 26 yrs ago with the birth of my first child, I weighed 123 LBs. The MD immediately put me on Sythroid and I have been on it ever since. I feel like the man who spent 20 years in prison for a crime he didn't commit. I have gained 100 pounds, have fatigue all the time, wanting to die at times, joint pain, saw a Rheumatologist 4 yrs ago, who says I have RA but can't quite figure out why. I now have developed ear fullness, pain in my ears, pressure headache, neck ache, dizziness at times, joint pain at my hands a feet and now I am am losing my hearing. Isaw an EMT who said it is nerve damage and that the ear pain and fullness and dizziness is from TMJ! of which I have never had in my life! Thank you all on this blog because I have stopped the Sythroid today and will ask my MD for Armour Thyroid. Thanks again! F 53 26 years

 2  partial thyroidectomy, Hashimoto's Intense joint pain in elbows, knees, and hands. Inability to sleep through the night. About a year after a partial thyroidectomy, I developed symptoms of hypothyroidism. My endo put me on a low (25 MCG) dose of Levothyroxine. This helped alleviate most of the hypo symptoms... however, I'm now experiencing joint pain so severe that sometimes I struggle to turn on a faucet or lift a carton of milk. I also experience occasional depression and frequent insomnia. Any advice on how best to alleviate the joint pain would be most welcome, but my doctor just says, "take some ibuprofin." I can't help but associate the onset of the pain with taking the thyroid hormone - I don't think it's a coincidence. Incidentally, becoming hypothyroid coincided with menopause (or possibly triggered it?) and I'm aware that depression and insomnia are common at this time of life... but that does not explain the joint pain.

 1  Hypothyroidism anxiety, nervousness, extreme fatigue, depression to name a few. I took this product for nine years, because I was ignorant to the fact that there are other alternatives. Doctors ignored my symptoms. I do believe Synthroid caused problems with my Central Nervous System. F 36 9 years

 5  Hashimotos/Hypothyroid Regulates my hormone levels just fine. Have had to have the dosage increased as my thyroid dysfunction increases, but no side effects from the drug itself. If your endocrinologist prescribes Synthroid, do not let your pharmacy give you a generic or other brand. There are major differences between the various natural and synthetic thyroid brands, and generics do NOT have the same formulations as the proprietary brands. If one brand doesn't seem to be working, talk to your doctor about switching to another. But stick to a single source. F 45 4 years

 1  cusp hypothyroidism Weight Gain, Bloating, Painfully cracked lips, chest pressure I have been on the cusp of hypothyroidism for years and have fought taking medication. Since going through early menopause, I had trouble losing weight, even with exercise. I gave in to taking medication after my newest Dr. told me it was "beneficial". After taking Synthroid for a couple of months I told my Dr. about my weight gain and she raised to 50 mg to speed up metabolism. I have not lost the weight and feel bloating. I also told her about my cracked lips and she offered to refer me to a Dermatologist because she never heard of this drug having this side effect. She told me that my body needs to get used to the drug. I want to stop taking it and take a homeopathic approach. I am sorry I ever gave in. F 42 3 months

 5  Hypothyroidism None, although recently have experienced joint pain that has not subsided I have been taking Synthroid or Levothyroxin (depending on which GP prescribed and what insurance I was on) for 30 years. I feel it has done its job well. I have suffered throughout the years with other issues that have similar symptoms as others described in this post such as severe fatigue which was diagnosed as hyperparathyroidism (parathyroid is different than your thyroid). Once I had the offending parathyroid removed I felt much better. I have never been heavy but I also do not lose weight when exercising regularly and watching what I eat. I am also hypoglycemic so I eat very well. F 47 30 years

 3  Hypothyroid Lack of energy, headaches, tinnitus I have been on Synthroid for 15 years. At the beginning it worked great. Recently after severe stress, my body went out of balance. The doctor switched my dosage from the 100 mcg I have been taking for 6 years to 125 mcg. I have been sick for the past 4 months after tapering down from 125 to 112 and to 100 again. I have dizziness, severe tinnitus, insomnia and headaches. I attribute this to overdosing on Synthroid. Everybody is very different. I can only judge Synthroid for what it does to my body. It has very different effects on different people. I notice that stress plays a huge role on thyroid function. Overall and despite what I am going through, Synthroid has been a fine drug to be on.

 1  hypothyroid disease headaches, weight gain, mood swings after reading all the reports and thinking I was the only one experiencing these side effects, I now realize it was the medication. I was on weight watchers thinking it would help me loose weight and I gained. Fact is I was eating more food on weight watchers than I did on a daily bases. Synthroid has made me gain weight at a rapid pace! I am a laid back person and I could snap at any time at anyone for no reason. F 44 3 years
