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  Hypo (supposedly) Lethargy, brain fog, hair loss, achy joints, and WEIGHT GAIN. Well, it's been six weeks since my last post and I went OFF SYNTHROID and so glad with no regrets. I am dropping weight, feeling good and back to my old self. I decided to go the homeopathic route and feel the actual supplements working more for me than that god awful drug. I am going to contiue to have my blood TSH monitored, just so I can prove to my doctor how badly she screwed me up. That distended stomacj thing is almost gone, that was truly awful. Never again. Best of luck to all! F 38 1.8 years

I feel hypo now (joint pains, etc.) Just went to the Doctors and tests were great (so he says, showed me) told him I feel like crap, blew me off says it takes awhile???????????? F 46 2 years

 1  hypothyroidism I was diagnosed with an underactive thyroid in April through some blood tests at the OB-GYN because I told her I was feeling tired a lot. I have been taking this medicine for about 4 months now since then every day I feel worse and worse. I am only 24 years old and I have severe joint pain, chronic fatigue, brain fog, I can't concentrate and I have a hard time remembering stuff, ringing in the ears, I can't get enough sleep and I wake up all throughout the night, anxiety and in July I had a panic attack and had to be rushed to the Hospital by an ambulance, no sex drive and horrible periods. I used to be a very positive, outgoing person and now all I want to do is sleep and be at home. I just don't feel like myself anymore. I am ready to stop this medicine and try something new. F 24 4 months

 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

 1  Thyroid destroyed weight gain, tired(lack of entergy, moody,extremly dry skin, cold all the time. I go to my doctor every three months to have my blood tested and he says it is fine to stay on the .50, i keep telling him it's not working, I shouldn't have the side effects that I have. The medicine should be making me feel better not worse! F 35 2 years

 2  hypothyroidism hypothyroid symptoms Was on Synthroid for 6 years following my first pregnancy and never felt right. Brain fog never went away, tired all the time, and difficulty losing weight. Switched to Armour Thyroid about 5 months ago...brain fog went away as soon as I started taking it, fatigue lessened and weight is starting to come off. Libido is also coming back. I feel like I have a brain again, I can remember and comprehend things again! F 39 6 years

 1  graves disease deep depression, hair loss, broken nails, loss of libido, sweating-ruined clothes and sheets I was extremely upset to read Dr Arem's book and found out there is such a drug called antithyroid which I could have been treated with except that the medical profession had deemed I was too old(49-the cut off was 45) even though my primary dr thought I was much younger because before this I was in excellent health!I was taking synthroid for 14 years and began experiencing the old side effects it was supposed to treat. I gradually went off it and began taking herbal supplement and vitamin replacement. I am no longer depressed but still have achey joints.. I went to my local health food store and talked to the owner who said he began his business because his wife had the disease also. She is now on a low dose of zoloft. My husband took that for 10 years. It made him think he was better but I and our children were terrified of him. When he got cancer we went on a completely vegetarian diet and he was able to go off it and became a completely different person. Also I lost 22 pound F 14 years

 4  Hypothyroidism I experience some hair loss and general anxiety. You know i keep asking my doctor if there could be a link between my anxiety and my thyroid meds and she is sure there isn't. I just can't imagine there being so many of us with the same problem yet no link established by the medical community. I get bloodwork done every 9 months and my numbers are normal. I distinctly remember my anxiety presenting itself shortly after i began the meds 5 years ago. It doesn't make sense to me. F 47 5 years

 2  Hypothyroidism Weight gain (distended stomach), lethargy, hair continuing to fall out. I cannot begin to explain and I understand there are many stories like mine, but when my weight gets in the way....Houston, we have a problem. Do doctor's think you're lying about what you eat when they see the weight going up. I have been an avid runner all my life and have weighed 118 pounds since I have 15, even after the birth of my two sons. Seriously, I have put on 22 pounds, still run, have totally cut my calories below 1200, which anybody who knows nutrition...it's dangerous. I am trying a supplement next month. I know my body well enough what to look for and what to watch for. The grossest thing ever is this stomach thing. I have had a washboard stomach most my existence. There's got to be something more to this medication that someone is not sharing. If anyone else has made the conversion to a natural supplement, pease share, I'm curious. F 38 1.8 years

 1  Hypothyroidism Breast Cancer Within my start of taking Levothyroxin I noticed a lump on my right breast. Two months later I have an invasive lymphocarcinoma diagnosis. NO family breast cancer history, no previous cancer at all - but it had spread into my lymph nodes within a two month period. DO NOT TAKE THIS DRUG. Research on the internet has shown links between synthroid and breast cancer, but it is not listed on the side effects as it has not been "officially" proven. Stay away from this drug. F 45 2 months

 1  Thyroid removed (hypothyroidisim) Achey bones, loss of hair at times, hormone inbalance, irrotable, flu like symptons at times, fatigue, low energy, low calcium, cholesterol levels are always up or down, even with same diet and excercise, hard to loose weight, feel crummy! I had my thyroid removed 10 yrs ago due to multinodules. I was put on Synthroid & immediatly gained 20lbs and felt horrible. Felt worse after giving birth to my son.My dr kept telling me that my blood levels are fine. Yet I still feel tired, I could sleep for a day and miss work, my bones ache.I feel like my 20's came and went and now in my 30's I refuse to let more time go by.I am losing my hair in sperts.I thought that it was just my blood levels, and she played with my dosage not helping. Now that I am researching I really feel it's the Synthroid. I did the master cleanse and stopped taking everything for 10 days. I had never felt better, but I still need to be on something because I do not have a thyroid. I've talked with my dr. and she insits I be put on anti depressants. I am not depressed but will be if they can't seem to stop masking the problems with more meds and start finding out what is wrong with me. I just went in on Fri. with all my vitamins, research I've done, qu F 31 10 years

 1  My Thyroid was removed Cannot lose weight, tired, achy bones, mood swings, intolerable to heat, emotional, emotional, emotional, hair loss, dry skin, sometimes could sleep for a day straight just get up to go to the bathroom, constant sinus infections etc... I had my thyroid removed when I was 21 and have been on thyroid ever since. I seem to gain a few more pounds a year and my symptoms get worse. My blood levels are fine and my doctor looks at me as if I am going crazy and need anti-depressants, why do they resort to anti-depressants instead of figuring out what the problem is? I have been considering stopping my 150 mcg daily dosage. I did the master cleanse for 10 days and didn't take my synthroid, I have never felt better. Has anyone out there stopped taking their medication and tried to replace it with natural boosters and/or iodine? I can't take the side effects and can't seem to get any help from my doctor. Sometimes I wonder if they are controlled by the makers of these medications. My calcium levels have also lowered. I am 31 and shouldn't feel like this. I feel like I have been robbed of my prime years. My husband must get tired of my constant complaining. I don't even have the strength that I should have. I can't e F 31 10 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

 2  I don't know don't know if it's the meds or if something else is wrong with me.....fatiuge, loos of appetite, moody I am extemely underweight and had lactation 18 months after delivering my son and never breast fed. I complained to my doctor and was ignored. So, I went to a new doctor and she says my numbers are high and I have been on for 3 months now. I have a lot of these side effects, but I don't really know what to blame. Is it the meds or the issue. Not that I even know what's wrong with me. Since I have been taking I am very tired, moody, and haven't noticed any change. Is 3 months long enough? F 25 3 months
