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)

 4  hypothyroidism I have a family history of thyroid disease. My thyroid problems were finally diagnosed after I developed severe post-partum depression following the birth of my first child. I found an endo who didn't just look at "are you in the normal range" but looked at WHERE I was in the normal range. I was put on Synthroid when Armour Thyroid was taken off the market. While it was better then nothing, it just didn't work as well as Armour for me. I am back on Armour, thanks to the local compounding pharmacy, but still take 12.5mg of Synthroid daily. While I much prefer Armour, if this was all that was available, I'd take it and work with my endo to get the dosage where I need it! F 42 10 years

 2  subclinical hypothyroid Sweating,shaking,irritable,crying spells,hot flashes,huge appetite increase,bloated looking fat belly,weight gain,eye pain,insomnia, anxiety,faster hair and nail growth,ACNE,oily skin,elevated blood pressure and heart rate My doctor put me on Synthroid when my TSH was elevated to about 5.6. She said that I was subclinical HYPO,and I should try it. She started me on 50mg a day,and it was just awful! She lowered me to 25mg,which was still bad,then half of a 25mg, and I just still could not feel good at all. I have quit taking it and feel so much better. I'm sure this drug works great for others,but it is my opinion that I did not really need it. I think my TSH was only slightly elevated because I had been taking MELATONIN to help me sleep and I have found out melatonin can actually decrease your thyroid's ability to function if taken for a prolonged period of time.

 2  Hypothyroidism I had irritation in my lungs each time I took it. When I told my family doctor, he said that there were no side effects, but if I thought there would be some, then there would be. I was pretty much insulted. I actually did research on the inactive ingredients and found that it contained the following: Acacia, confectioner's sugar (contains corn starch), lactose monohydrate, magnesium stearate, povidone, and talc. It also apparently had some red dye in it which was part of the pill. I called the pharmacist who told me that Levoxyl probably had the least inactive ingredients in it. When the doctor switched me to that (at my request) I had no more problems. Synthroid irritated my lungs, perhaps due to the dye in it or the other inactive ingredients. Switching to Levoxyl solved the problem. I had to do research on my own, as my doctor said there were no side effects of Synthroid. M 49 7 days

 3  Graves then Iodine 131 dysthemia, fatigue, slow cognition, dulled memory, water retention I have been on doses ranging from 150 to 200 mcg. over almost 30 years. This drug alone is not sufficient to replace normal thyroid function. Combination therapy is the proper treatment. Find an Endo who will allow you to add small supplements of T3 (Cytomel 5 mcg) or preferably Armour (1/4 grain). Armour has calcitonin, T1 and T2. They make a difference: only then will you feel normal. M 44 27 years

 4  Hypothyroidism I am clinching my teeth causing extreme sensitivity to warm, cold, even hard foods-noticed this when i started but figured it would go away once my body got used to it and now it is getting worse. And I am figiting - this just started within the past month. I do not see very many people with clinching their teeth but it has to be this medicine. My problem was caught right as it started acting up so, I didn't have any issues. I was just doing blood work for school and it was caught. So, as far as I know it does its job but the teeth thing is really bothering me and I am wondering if the dose it too high? F 28 1 years

 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.

 2  Exhaustion and stomach problems Joint pain, anxiety if dose increased to .75mg Why don't doctors acknowledge the joint pain. I am 46 and try to be physically active and the joint pain is slowing me down. I know the joint pain and anxiety are related to the medication because I first notice these symptom when doctor put me on higher dose. When I complained and we lowered my dose, some of the pain subsided. How do you get off this medication? F 47 10 years

 4  half of thyroid removed a year ago I've started to learn my body and symptoms of when my thyroid hormones are getting low or high. Low - get really tired and cold. High - hungry all the time, slight anxiety, trouble sleeping. Heavier periods, insomnia at times. I took the generic of this drug and had horrible side effects, anxiety and panice attacks at the top of the list. Once I started the Synthroid, symptoms starting improving. It took awhile to get the dosage correct. I've now landed at 75 Mg five days per week and 100 mg the other two days of the week. I've started to learn my body and symptoms of when my thyroid hormones are getting low or high. Low - get really tired and cold. High - hungry all the time, slight anxiety, trouble sleeping. The one thing that has been constant since having half of my thryroid removed is weight gain regardless of food intake or exercise. I'm gained 35 pounds since the removal. Synthroid hasn't seemed to help in this aspect at all, matter of fact, the constant hunger when my levels went to high caused me to eat more than I would. Overall, I would recommend this to others. It's given me my energy back, and helped me feel more like myself again, although not perfect. F 37 7 months

 5  Hypothyroidism None I was constantly struggling with my weight, was tired all the time, started getting hair where there shouldn't be any (upper lip, etc.), and irregular and excessive menstrual cycles. I was always skinny even without having to work out. After having my first child at the age of 21, I gained 60lbs during pregnancy, despite the fact that I ate nothing but healthy foods. It all went downhill from there! I had hit 220lbs before I knew it and no matter what dieting or exercise I tried, it did not help. I had seen a couple different doctors and let them know of my problems. I also had problems becoming pregnant again. They just slufted it off as me being lazy & whatnot. Then finally, I met a doctor that decided to check my thyroid. She was shocked by the results! It took a while to finally get the right dosage, and because of moving a couple of times I had to change insurance & doctors, but as soon as we found it I felt an immediate change! In only 4 months I had lost 30lbs by only counting calories. It was amazing!! Then, after 9 years of trying to get pregnant, even trying clomid for several rounds, just 5 months after getting the right dosage I became pregnant!! This medication has changed my life!! Never thought the thyroid controlled so many different things! F 30 5 years

 4  hypothyroid none It helped clear up my acne & cold sores, also stopped me from being cold all the time, and my hair was falling out, now it's nice and thick. The only thing that Synthroid didn't do that I was hoping it would was to help me lose the 30 lbs I put on when my thyroid went haywire....so far that hasn't happened. F 53 1 years
