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  Hypothyroidism - Hasimotos Weight loss, increased appetite, occasional insomnia I have been on Synthroid since my doctor realized I hadn't been growing like I should be at the age of 8. Taking this drug completely changed my quality of life for the better, and I don't know what I would do without it. I also found that taking it in the morning may help overcome any insomnia, and also taking this prescription within hours of any iron pills usually caused stomach pain. F 19 11 years

 1  Medically induced hypothyroid On the generic foggy headed, tired and depressed. My dose was 100mgs and 112mgs every other day. When I switched to the name brand synthroid exactly three days after starting synthroid it was like dynamite going off in my brain, severe TMJ, pressure in my head, ear ringing to an excruciating degree, stiff neck, peripheral neuropathy, rash, mental instability, inability to sleep, numb lips, inappropriate chest breathing, tingling on the tip of my check to a serious distraction, racing heart, carpal tunnel symptons ect…With these symptoms my numbers were normal. We reduced my dosage to 88mgs, it took weeks for me to be able to sleep and not feel like I took 100 hits of amphetamines, and now I still have neuralgia in my face and teeth, rash cannot get rid of it, on and off ear ringing, peripheral neuropathy and tipping and racing heart on and off. I was lethargic and tired so I am trying to bring my numbers up slowly by increasing my dose to 1MG twice a week and the other 5 da The thing is if you make the wrong decision in brand or dose the affects will make you so miserable it isn’t almost worth doing. You already know what hell you are going to live on the brand and dose you are on. The unknown you soon learn can often be worse. It takes a long time as well. It isn’t like an antihistamine that you can adjust quickly the nightmare of a bad body match with brand and dose can go on for months. The makers of these drugs and the doctors don’t care. They all get paid whether we are satisfied or not. Actually the doctors and drug companies make more money if we are not satisfied with our treatments we search for answers and comfort at our expense. My doctor is a very good and caring doctor but he does not believe that the synthroid is the problem and keeps testing me for MS, Lupas ect..all which keep coming up negative. I never believed in alternative therapies but my chiropractor has been a godsend and has gotten be through this nightmare! I just want to work, travel, hang with my dogs and family and live my life..somebody find it for me I seemed to have misplaced it…if you see it please return and I will look for yours cause this hormone replacement therapy is a living HELL!!!!!!

 3  Hasimotos Anxiety, depression, paranoia. I was diagnosed with Hashimoto Thyroiditis 13 years ago. I started out taking 50 mg Synthroid and then moved up to 75 mg. Four years ago a surgeon almost talked me into having my thyroid removed because of the enlargement of my neck. I thank God every day that I decided not to have it removed and I went for a second opinion. I didn't need my thyroid out. My regular physician then increased my dosage to 100 mg and I have been experiencing terrible side effects ever since. I had also taken singulair for a brief time and thought I was going to commit suicide. It was the most horrible medicine I have ever taken! For the last four years I have been looking for something to help my thyroid. I am now on my way. My chiropractor started Nutrition Response Testing in his office. It's the best thing I have ever done. I have been taking Thytrophin PMG and Prolamine Iodine for my thyroid and it is working to strengthen it naturally. I had my bloodwork done this week and my PCP called me today to decrease my synthroid to 50 mg. My goiter is going down. I don't remember having these side effects from the synthroid when I started out at the 50 mg so I researched to find the ingredients in the different synthroids. The 50 mg has no color additives nor does it contain any Aluminum Lake. The other one's all do. This might be the ingredient that causes so many terrible side effects. I have learned from research over the last 4 years that artificial sweetners, colors, preservat F 33 13 years

 5  Hypothyroidism - Thyroid damaged None I'm on natural Synthroid (much more expensive), not synthetic Levothyroxin. Over the counter vitamins do nothing for me. Herb based vitamins do work for me. I would not stabilize on Levothyroxin. I did on Synthroid. Before hysterectomy was on 175 mcg. After hysterectomy rapid weight loss (2 pounds a week) and heart palpitations. Reduced dosage cured that. Tried Levothyroxin after stabilizing after hysterectomy, sent me into imbalance. Back on Synthroid, stabilized but not loosing weight. F 56 18 years

 1  Hypothyroid THIS drug stole 30 years of my life. I thought I was just a nervous scatter brained though Ph.D. absent minded professor. I stopped sleeping well at 13. As a result my skin, concentration and entire life turned upside down. I spent 20 years avoiding medications (other than synthroid, which i was told i had to take) by using acupuncture and herbs to keep the "heat" and anxiety away. WHAT A NIGHTMARE thank god i am off this medecine. My husband and children will benefit for years to come. I believe if I had continued my hypo would have turned into graves disease. Synthroid is over prescribed and is NOT a weight loss pill as it is often sold to people. I wish I had know about the class action suit. F 43 30 years

 5  Hypothyroidism No side effects that I've noticed. Was just increased to 75 since my thyroid levels were off again. I put on probably 10 pounds in the last 6 months but in the 1 month since I've increased my dose, I've lost 8 pounds already so I guess it was my thyroid keeping the weight on me. Thankful that I had labwork done last year and found that I had hypothyroidism because since I've been taking generic synthroid, I feel much more energetic and with the increased dosage, I'm losing weight and sleeping better.

 5  Thyroid Cancer Total Thyroid Remova This changed my life! One endocrinologist insisted my 80 pounds of weight gain in 1 year was due to my personal 'lack of self control' and he recommended I get a lap band! I was on 30mcg at the time, with NO thyroid due to thyroidectomy. New Endo, new drug amount and POOF within 7 months I lost 60 pounds, energy returned, life restored and I would never live without it!! Prior to proper dose I had blinding headaches, muscle cramps, low energy, falling-asleep limbs, swollen fingers uncontrollable bouts of crying/emotions. EVERYTHING that was NOT me!!! Proper dose gave me my life back and I'm back to everything physical I could not do! Don't ever want to live without it!! F 40 1 years

 1  Hypothyroidism Extreme, constant hunger accompanied by severe nausea (24/7), constipation (regardless of how many fruit and vegetables I eat), heart palpitations, fatigue,shortness of breath and elevated heart rate and blood pressure... OVERALL COMPLETELY MISERABLE!!!!! OH, and I can't forget... Weight gain!!! AND hair loss and brittle nails!!!! As well as my skin being just terrible! I have never been so sick for so long in all my life!!! I would rather deal with the hypothyroid symptoms and problems than to ever take this medication again. I have always battled with even having an appetite to eat (I could go all day before eating anything) but on this medication I could not eat enough to satisfy the unbearable hunger and severe nausea I underwent literally 24/7 with no relief at all (I had hunger pains even while I was eating and after I was done). I am thrilled for those to whom this medication works for, but it was not for me!! I have been researching for days trying to find out why I was so sick since this is a "natural" hormone that "should not cause side effects" and everywhere I have looked there were no real answers. There has got to be another option or treatment for those of us whose bodies simply cannot tolerate this medication or its generic counterparts. F 33 7 weeks

 4  Total Thyroidectomy due to Cancer none really - bad menstrual cramps first 24 hours of cycle, but other than that can't complain. Before my thyroid was removed, I was underweight and nervous all the time. Now I feel more like what I suppose a normal person feels like - not so agitated. I do find that exercising regularly helps me. F 31 18 months
