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  goiter noticed at age `` I am 61 and have been taking hyroid medicine for 50 years. IN APril 2006 I ran the Boston Marathon and biked 300 miles the next week. At age 51 I had the doage increased because I was feeling tired. The dotocr gave me a blood test, and the small increase in dosage increased my energy within days. I am a vegetarian, keep my wieght down, and do hard workouts. M 61 50 years

 5  Hypothyroidism Ive never noticed side effects from this drug -- negative or positive. I felt great in my early 50's -- assumed I was in perfect health -- when my GYN routinely discovered a goiter. I was sent to an internist who put me through numerous tests and subsequently prescribed Synthroid (and told me never to take the generic brand). I've never felt any different than the day I began taking the drug, however, I see the annual test results so I'm sure I need it. My dosage has increased several times; I presently take 150mcg. I've developed aches and pains in the last 10 years, but at my age who hasn't -- and Synthroid probably has nothing to do with it. F 63 10 years

 3  hypothyroid My blood pressure climbed from 90/65 to 120/70. I can feel my heart beating in my chest and my head. I have pains in my heart/ possible heartburn. My digestive system is upset. I can't focus on work. On the plus side; I am sleeping better and not waking up lethagic with brain fog. My allergies, depression and muscle aches are so much better. I am only on 12.5 mcg which is an extremely low dose. I only weigh 105 pounds. My doctor wants me to increase the dose but I am concerned about my stomach, my focus and my heartrate. Has anyone tried a compounded dose? or a compounded dose from a naturopath? I have tried Armour and had the same symptoms. thanks so much [email protected] F 53 1 months

 1  hypothyroidism after several months on the meds my knees and shoulders started to ache, then my hips. I can't get in or out of a chair. I now have carpel tunnel in both hands. Torture!! My doctor said these symptoms result from the hypothyroidism. I switched to Armour but no change. M 52

 5  hypothryoidism Slight fluttery feeling in my chest the first and second day on 25 mg dose. From all I'd read and heard, even from my doc, I expected to wait at least a few weeks to see any improvement. Instead, I noticed significant improvement on Day 1 and it has only gotten better in the 3 days since. I don't have that crippling brain fog (that was serious impacting my job performance), have energy to spare. The joint aches are gone, I sweat again, my recovery time from a gym workout is back to normal. I am astounded and very grateful. I go up to 50mg in a few days and will update this then. My thanks to all who posted before--your comments (-and +) helped me a great deal! F 44 4 days

 5  hypothyroidism None at all I take 200mcg. I have taken it for 6 years. If there have been side effects, they have only been positive: I am able to lose weight if I try, I am not freezing to death all the time, and I am not ready to hibernate for a long winter's nap by noon each day. Synthroid is great. It has completely changed my life for the better. F 39 6 years

 3  Hypothyroidism Hip and joint pain, knee pain. I have been on this medication for about six years after taking Levothyroxine for about six years prior. I feel my body is able to tolerate Synthroid better than Levothyroxine. Would love to not have take the medication at all!, but I prefer Synthroid over Levothyroxine. F 36 6 years

 4  Total thyroidectomy, thyroid cancer Muscle aches in back and legs. Tingling in toes, fingers, legs, arms. Stiffness. Weak ankles. I am taking 150 and it seems to work really well for me. My levels are good and I feel pretty good overall in that I have energy and little fatigue. My only complaint are the weird aches and pains I have experienced in the last few months. I don't remember feeling this way prior to taking this medication. I have been on Levothyroxine for approximately 1 year, and in the last four months I have noticed these problems. I don't know if it is a side effect from the medication, but nothing else makes sense since I am not on any other medications. I have talked to the specialist about the tingling and numbnes but he didn't have an answer for me since my levels look fine. My calcium levels were also fine, but should I take a supplement anyway? Does anyone have advise/suggestions? F 29 1 years

 3  subclinical hypothyroid Weight gain after being on it for 6 months. Energy seemed to increase a little, but after about 6-9 months I hit a wall and crashed! Perimenopause also causing problems. Not sure if fatigue & weight gain are from synthroid or estrogen dominance,etc. My body temp, blood pressure, and resting heart rate all stayed very low. Dr. was concerned that I might lose weight, but I ended up gaining 15 lbs after taking generic synthroid for 18 months! Eating lots of raw, organic fruits & veggies helps - but not much! Very worried about all the negative comments about synthroid and t3 (which was added to my RX last month. Would prefer to have Dr.s treat patients with more respect and offer natural alternatives, rather than just throw another RX at us!! F 45 18 months

 5  removal of thyroid to nodules None, except when they had my levels to high, I was having anxiety It is great if they can keep levels controlled. I had my thyroid removed in Dec/of due to suspicious nodule and hashimotos. My levels have been messed up ever since, so I hope this new dose I am on straigtens things out. F 28 3 years

 2  hypothyroidism TSH 7.0 confusion, racing thoughts, insomnia, acute pain in mornings and drugged sleep, takes an hour just to wake up, dizziness, 30 second attention span, forgetfulness I can only take 25 mcg. Above that I get attention deficit symptoms described. My Doc told me I had mental problems, which is untrue, psychiatrist backed this up. I have no relief from fatigue at this level and no-one seems willing to experiment. When I asked for Armour I was told to find another (UK) practice. My opinion is that there is a mental health crisis amongst many of our doctors. They are in denial about these problems. I had a mild form of hyperactivity/attention deficit before this illness which synthroid exacerbated. Any suggestions appreciated! M 61 18 months

 5  hypothyroid None at all It took some time to get me stabilized, but once we got up to the proper dose, my blood levels have been stable for several years. F 31 7 years

 5  Hashimoto's thyroiditis None at all. Been on it 14 years now. Over the years I had a few symptoms but it was always because the dose was too high or low; body change/prescription issue, not a side-effect issue. F 42 14 years

 4  hypothyroidism/goiter some racing heart loss of hair due to too much By the time I could get anyone to diagnose me I was feelin' pretty ill. After a week or 2 I felt great! I had read some horror stories but as with all meds it can vary from person to person. I experienced some hair loss and racing heart/palpitation but my TSH was at .02 so I was on too much medicine at .075mcgs. Now on .050 and feel great!! F 34 3 months
