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)

 2  Hypothyroid Exhaustion, steady wt gain in spite of low appetite & frequent exercise, pains in hands, feet & outer hips, difficulty thinking clearly, obnoxiously teary. On 'max dose' for close to 40 yrs after undergoing radioactive iodine ablation. Sometimes test results would be in the low normal range of 4.0-5.5, sometimes above 6.0. Was refused higher doses because it 'might cause osteoporosis'. Have switched to Armour Thyroid - doc doesn't like it, but I'm feeling human again, & close to 90 pounds literally fell off. Not perfect, but wishing I hadn't lost almost 4 decades before finding there was an alternative. Also found there is a 'sweet spot' at the high end of the new range of .3-3.0 where I feel best, though doc is also resisting that idea. If Synthroid isn't working for you, Armour is worth a try. It's also faster acting & cheaper. F 55 38 years

 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

 2  Low free T4 / free T3 - hypothyroid Not differences noticed at first, but gradually started experiencing suicidal thoughts, extreme sadness, etc. that wasn't there prior to Synthroid. I think it may have something to do with needing more T3. Taken first thing with water then no food for 1 hour. Also taking prometrium (progesterone) and dhea. I have thyroid-adrenal-ovarian imbalances. F 32 2 months

 4  Hypothyroid weight loss, goiter went away, increased energy. Normal BM's. I was diagnosed very young with hypothyroid, It took a long time for my goiter to go away and my weight to even out. Recently I've noticed that my energy has decreased and my neck felt swollen. Just had an ultrasound done, now I have a tiny nodule on the upper left portion of my thyroid. I just had an increase in my dosage from 75mcg to 112mcg. Doctor says it will take about a month or so to notice a difference. I am hoping everything returns to normal and that my nodules remain small and benign. All I can do now is wait an hope for the best. F 23 15 years
