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)

 3  Subclinical Hypothyroid Bloated, now I can't lose weight, and feel I was hypothyroid for years and no one would prescribe thyroid meds for me because I was borderline. I would sleep for hours everyday and have major brain fog (Everyone chalked it up to being a mom or blonde-haha). After taking synthroid, I felt as if someone turned a light on inside of me---I now have major energy and feel pretty good. The only side effect is not being able to drop one pound, even if I run on my treadmill for 45 minutes per day. F 35 5 months

 3  Extremely low thyroid function None so far! I have recently been diagnosed with hypothyroidism and I have no symptoms of it. However my blood test show extremly high thyroid antibodies, 417, and my TSH is 10! I have recently lost 50 lbs and I don't understand this disease at all! Now after being on the drug two weeks, I have gained 5 lbs! Anyone else experienced reverse symptoms such as this? F 24 2 weeks

 3  Subtotal thyroidectomy I had a lot of issues with my thyroid after finding a large mass on the right side. Well needless to say that is when the problems I was having became understandable. I have noticed since reading these ratings that alot of people are in the same boat I am. I have had weight gain (unexplained), tired all the time, joint pain, hair loss, etc... and the joint and stomach pain started after I began taking synthroid. I can say it has helped a little, but I still suffer from insomnia, joint pain, hair loss, weight gain, stomach pain, extreme hot and cold. Some days it is not as bad and others it is horrible. The odd thing is the doctors usually tell me my levels are ok. Not a huge fan of taking this for the rest of my life, that is for sure. F 25 2 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

 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

 3  Hypothyroidism Bone Pain, dx'd with Osteoporosis last month, body aches and inability to lose weight. I was diagnosed hypo at age 19, put on Synthroid and have taken from 50mg starting dose to where I am currently, 300mg. Initially for the first ten yrs it worked great. Then slowly it began to be less effective for me (or I developed a tolerance of some sort). Doc wants to raise my dosage again to the highest amount possible but I am totally against it due to the osteoporotic factor that this med caused in me. F 41 21 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

 2  Hypothyroidism Hair loss, muscle aches, heart palpitations, racing pulse, heart felt like it was pounding in my head, increased blood pressure, insomnia, shakiness when I try to walk, hand tremor. Two months after starting Synthroid, I went to a hospital twice in one week because of scary heart symptoms. Doc said I was not overdosed because my TSH was 4.9. Was given Xanax and a beta-blocker to control the cardiac symptoms. I was an avid runner for 15 years before becoming hypo, but I don't feel like running now. My body temp is still around 97F in the morning. If I don't get better soon, I will ask for Armour. F 55 3 months

 2  hypothyroidism Depression, mood swings, weight gain, anxiety attacks, lack of focus I was diagnosed with Graves Disease and treated with RAI causing me to become hypothyroid. When I first began taking synthroid I felt great and began to loose weight, however, within three months I began having hyperthyroid symptoms again. After two adjustments, I am supposedly on the correct dosage, however, I feel awful. I have up and down mood swings, depression, anxiety attacks, weight gain (1-2 pounds/month), and I find myself going from task to task and never being able to complete anything. I feel like I am going crazy! I have been to both my endocrinologist and my ENT and both say that my blood levels are normal on the .88mgs that I have been prescribed. My doctor now wants to treat me for depression, but I feel like she would be treating a symptom rather than finding the problem. I wish I knew what to do! F 38 1.5 years

 2  Hypothryroid Hungry even after eating a meal. Heavy cravings for sweets. Constantly having migraines. And eczema all over. Con't from a previous entry, I have PCOS, had a baby 2 yrs ago now and was dianosed as hypothryroid shorly after conceiving. At first I took 0.075 mg of synthroid, but decided to see an endocronologist because I was gaining weight with this drug and getting eczema all over. Now I'm taking 0.125 mg of synthroid, and sadly, I'm still gaining weight, I have reach 220 lbs. I continue to be hungry all the time, and my cravings are out of control. I just want to take something that works and helps me lose weight. Waiting for my 4 month visit to happen in Feb 07, to see what the specialist has to say. F 32 1 years
