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  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

 1  Hashimoto's Hypothyroidism HAIR LOSS, weight gain, difficulty losing weight, foggy thinking, makes everything look good on tests without treating my symptoms I took this for about a year before my hair starting falling out. My doctor switched me to the name brand (I was on the generic before) and it didn't make a difference. Every few months my TSH creeps up and every time I need to increase my dosage yet again. High TSH, low TSH, my hair continues to fall out. I was really sick with hypothyroidism and my hair didn't fall out, it was only after taking synthroid. It's also much more difficult to lose weight.

 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

 1  hypothyroidism Fatigue, inability to cope with stress of any type, significant weight gain, foggy headed, severe mood swings, prolonged and far more severe symptoms of PMS (lasting for 2 weeks) as well as longer periods (used to be 3 days now lasting for 5-7 for the first time in 25 years), depression, strange body aches which often wake me in the night, stomach boating, increased number of bowel movements (4 to 7 per day) somtimes very hard stool and other times regular (rarely experiencing diarrhea, insomnia, waking often with severely dry throat which causes a choking feeling, I began taking Synthroid at the suggestion of my GP due to elevated TSH levels (39) and my complaining of some symptoms which could have been caused by the improper function of my thyroid. Before taking I was experiencing periods of extreme fatigue, mood swings, constipation, weight gain (which I attributed to excess amounts of stress), and some minor muscles aches. Now my list of symptoms is as long as anyone else's who has experienced negative side effects from this medication. I was overweight by 50 lbs when I started and despite eating a healthy diet consisting of lean meat, fat free dairy, lots and lots of raw, steamed or roasted veggies, lots of fruit, optimal amounts of omega-3s and soluble fiber (strictly from diet, no supplements) and exercising 4-5 times each week (to include Tai chi for stress management, weight training under the guidance if a personal trainer, and cardio at a minimum of 30 min and max of 60 minutes) and this weight is only going up. All that are work and diligence and I have gained 20 lbs on 5 months. It makes absolutely no sense because my calorie intake vs. burn is exactly where it should be and nothing is changing. If it were a matter of muscle gain I would be noticing a change in the way my clothes fit, but I have had to purchase new, larger clothes. I am extremely depressed because of all this and find myself feeling very hopeless about this ever changing. The symptoms I'm suffering with my monthly menstrual cycle are awful. I have F 37 5 months

 4  hypothyroidism Weight loss, headache, nausea I have had a partial thyroidectomy and have been taking synthroid ever since. I have noticed about a 20lb weight loss without trying and an increased appetite. I have also had pretty bad headaches every now and then. Overall I am satisfied with this drug but it does come with side-effects for me. F 28 3 years

 4  born without thyroid As I was born without a thyroid I have been on this drug my whole life. When I was growing up I decided I didn't want to take this drug and always told my mother I had taken it. My doctor told me if I didn't take it eventually I would DIE. He tried me on the synthroid brand and I then started having more energy. I am able to work and play with my 9 year old daughter. Reading the other reviews some people aren't happy with this drug but finding the right dose for you takes time. I have found when I get my dosage upped 100+ it doesn't suit me, I am better on 75mcg or 100mcg. F 29 29 years

 4  Hashimoto;s None, apart from my skin seems to have gotten much more congested, more blackhead etc (should have been the opposite). When on too much, I experience heart palpitations. My hair is still falling out although less than before. No weight gain or weight loss, everything constant, weight was never an issue. I have been on Synthroid for Hashimoto's now for almost 3 years before that desiccated thyroid for 1.5 years. With Armour they just kept increasing it and I felt some change but not significant. Finally a doctor told me there would be no difference between it and synthroid, so I went on synthroid. Again, my dosage just kept going up without a significant improvement. It turned out just recently ( and I figured this out ON MY OWN and had to basically tell my doc what I wanted her to do), just the T4 couldn't be converted by my body into sufficient T3 (my TSH was indicative of this, as it was in overdrive), so I needed cytomel (i.e.T3) added to the synthroid and now I finally feel good. I am now on 112 mcg synthroid and 5 mcg cytomel twice a day. HAving said all this, my current endo has admitted that basically Armour is a natural combination of T3 and T4 (i.e. synthroid plus cytomel) and I think once I am at the right level I will go on it again, just to see if it works as well. I am also looking into alternative ways of healing myself as I do not want to spend a lifetime on synthroid and I am becoming more and more suspicious about the absolute need to take synthroid. Hypothyroidism is a veritable epidemic and I believe it has hugely to do with our diets, supplements and environmental factors. I am just wondering why doctors are so quick to put people on synthroid. I read " How i reversed my Hashimoto's thyroiditis hypothyroidism" by Robert Dirgo. F 38 3 years

 4  Hashimotos Itchy, dry skin for about 2 months, increased bowel movements. Weight did go up a bit at first when on the lower doses. But now back to normal. Doctor started me on 37mcg and after 2 months, moved up to 75 for 4 wks, 125 and then 137. I had major itching and dry skin for about 2 months. Energy wise, felt a bit better (wasn't needing daytime naps) but not amazing. After blood tests (t3, t4 levels) my t4's were a bit high so, was downgraded to 125mcg and Doc added .5mcg of Cytomel. I feel much better, clear thinking, a bit more energy. The plan is to add a second .5 Cytomel in a month. F 46 6 months

 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

 2  hypothyroid due to hashimoto's stomach bloating, weight gain, severe constipation, depressed mood, slowed speech, brain fog, itching, pressure behind eyes and at base of skull The only positive effects I have noticed from this medication are reduced facial swelling and thicker hair. Otherwise this medication is a nightmare. Each time I have restarted this medication, or when I have been on it long term, I get an extremely distended stomach, severe constipation, and brain fog.
