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  Thyroidectomy I had a thyroidectomy due to a multinodular goiter which was becoming very uncomfortable (hard to breathe and swallow). I was also told I had thyroiditis which caused a fluctuation between hypo and hyper symptoms which was very annoying because no one would ever prescribe me Synthroid because my levels were typically "normal". I was extremely afraid of the surgery only because of the horrible stories I've read when patients switch to synthetic thyroid hormone. HOWEVER, I am beyond happy I decided to have the surgery, on synthroid I feel so much more normal, no more hot and cold flashes, I am not tired and lethargic, I feel more normal than I ever have! I haven't even had to regulate my dosage, I think 75 might be perfect for me (around 110 pounds/23 years old) Do not be afraid to have this surgery, especially if you feel as much discomfort as I did, believe me you will not regret it.

 5  Hypothyroid None After my first dose I felt GREAT. Better mood, less tired, less muscle aches. Day 2 was the first morning in a LONG time that I woke up NOT feeling the aches and pains of a 90 year old. I took my 2nd dose and have felt fantastic all morning. It is now early afternoon. Usually I would start feeling very tired around this time and need a nap. I really hope this improvement keeps up! I realize it has only been 2 days, but so far 75mcg seems to be working. I take it first thing in the morning with a full glass of water and then wait 30 minutes before having my coffee. If anything changes, I will post a new rating. So far so good ;) F 40 2 days

 5  Thyroidectomies/Goiters When my medicine is too low I have hair loss, fatigue, memory issues, depression, sensitivity to cold, constipation, longer menstral cycles. When it is too high I have insomnia, hyperactivity, sensitivity to heat, diarrhea, shorter menstral cycles. When I was 13 I had the left half of my thyroid taken out with an egg size goiter. When I was 14 I had the rest of my thyroid and a quarter size goiter taken out. I have been on Synthyoid for more than half of my life and it works very well when taken as prescribed and and if you take it at the same time each day. F 28 15 years

 5  RAI after Graves Disease This medication does need careful and frequent monitoring with blood tests. However, when the dosage is right (for me) it makes a world of difference. Too much can mean heart palpitations, hyperactivity, increased appetite and insomnia; too little can mean depression, slugishness, mental bluriness. Find a doctor who will monitor you frequently. Your levels can change. F 35 20 years

 5  no energy,fluctuating thyroid level Hair loss only (but had hair loss before due to birth control pills) I was thin and energetic all my life but doctor said my thyroid may have been thrown out of whack due to a complete blood transfusion from a car wreck at age 21 where all the blood in my body was replaced but 2 units. I was VERY discouraged at first when I started out on Synthroid 50 mg because it didn't seem to take away my fatigue like I had hoped because most of my research had said after 2 weeks I should notice a difference. But after about 4 MONTHS I finally got my energy back and though I have not had any weight loss everything else has been a HUGE improvement. I have not experienced any side effects other than hair loss. Just this week my doctor changed my dose to 75 and I hope it will help with a little weight loss. I had gone for over 17 years being improperly diagnosed before a doctor finally recommended this so some of the delay in medicine absorption may have been due to the length of time I was ill with thyroid issues. So be patient and be persistent - and try different things like time of day taking it too (I tried it at night for a while but didn't seem to help though I have read it helps some people taking it that way) F 39 9 months

 5  Thyroid Cancer/Thyroidectomy Hypo Lots of side effects when dosage was not correct. When dosage is correct I feel great After the birth of my first child I was diagnosied with hypothyroidism and started taking Levoxyl 75 MCG. With the birth of each additional child the thyroid would become more diseased. During my pregnancy with my 3rd and 4th child my thyroid level became normal without medication which baffled doctors. During a 3 year period I was on a thryriod rollercoaster going between hyper and hypo. About 4 months after having my 4th child I began having hoarseness. Endo did blood test that showed my body produced the antibodies that caused graves disease and hashimotos (spell?) disease explaining my rollercoaster thyroid levels. One morning I woke up unable to utter a sound. After 3 weeks of not being able to speak my Endo finally saw me. Endo kept telling me I did not have thyroid cancer only a severely diseased thyroid and referred me to an ENT. First visit to ENT looked down my throat and located the thyroid mass that had gone through the wall of my larynx and scheduled a full thyroidectomy. Had thyroidectomy 21 months ago and finally have good blood work and feel the best that I have felt in 2 years. Since thyroidectomy gained 30 lbs, and now working hard and losing 1.5-2lbs a week and am down 26 lbs. The medication is not what makes you feel bad, it is when you are not on the correct doseage of the medication for you. Just because you are at "normal" range doesn't mean that is your best level. Most women feel better at the lowest end of the scale. F 32 11 years

 5  Hypothyroidism None This medicine is saving my life. I'm no longer tired, have no desire to stay in bed all day (this used to be the case), I'm able to get up and get moving without a struggle. Depression and moodiness are dramatically decreased, almost nonexistent. I swear I started feeling better after just a week of taking it, although many say it takes weeks, even months, to feel better. It kicked in for me pretty quickly and I'm happy with it. Zero side effects although I may have gained a couple pounds...however, I do NOT blame the medicine - I've been eating more junk than usual and I know if I cut back and get back to the gym it'll come off. The most important thing here is that I feel better, and I do. Maybe in the future there will be a need to incorporate T3 as well but for now I'm extremely happy on Synthroid. F 27 30 days
