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)

 1  hashimoto's Slow introduction starting w/12.5 to 25. No change in tiredness or sleeping symptoms, but hair loss slowed. Drug conflicted with theophylline and caused allergic asthma mild attacks. Increase in nausea, nightmares, itchies, brain fog and other symptoms. Had to take it at night with small amount of food in stomach which conflicts with instructions. So in general - not a good match. Too much filler - hard to figure out what is causing drug interactions. F 60 2 months

 1  hypothyroid Extreme memory loss; feeling of dissociation; tingling in extremities; extreme anxiety; insomnia; neck stiffness; lump in throat feeling; fogginess in head; loss of coordination; trouble finding words; tremors; extreme blood loss during menstruation; hallucinating, mainly auditory; fast heartbeat I thought I was losing my mind, feeling like my limbs weren't my own, hearing things, sounds being too loud (even silence feeling loud!!!) Panic stricken. Dizziness. Loss of coordination, and pcp thought it was an aneurysm from symptoms. Family terrified after hearing me talk, thinking I was having a stroke. I thought I was going to die. Husband told me he would call ambulance if I didn't go in for cat scan. This has been the most terrifying medication experience of my life. Different for different people, but how in the world could I ever recommend it to anyone. Terrifying, and it's still not out of my system. Still waiting for symptoms to clear and haven't taken't it since Saturday night (it's Tuesday). Still tremoring, stumbling on words, stiffness in neck. Memory's getting better, feeling less crazy. Still swollen hands and feet, and tingling in both. I would say stay away from this medication, as it feels poisonous to me, but I know it affects us differently. Most horrible drug on planet in my eyes. F 40 5 days

 1  Hashimoto's MAJOR Brain fog/ feeling drugged, low blood pressure, low blood sugar, headaches, occasional diarrhea,muscle weakness and major fatigue, low memory. When on 75 mcg I would have heart palpations, insomnia but tired, major diarrhea in the morning, and anxious. Have lots of bad days on this medicine. I know its the synthroid bc i was not feeling "drugged" before i was on it. Have no choice. All the doctors say its not synthoid but I find it hard to believe all these people complain of this dizzy brain fog feeling. Endocrinologist dont know crap and dont want to help. I would be on a million prescriptions to treat all these symptoms but I'm not going to fall for this. This is all bc of synthroid... im way to young for this crap and want my life back! F 26 3 years

 1  hypothyroidism It was the most horrible experience of my life. Water retention, hives-even in my mouth, boils, weight gain, depression, anxiety, heart beating so hard I could feel it hitting my hand when I put my hand to my chest, I was almost to the point of being suicidal, I'd cry at the drop of a hat, eyes bugging out, unable to focus to read.

 1  Hashimoto's Hypothyroid Can't lose a SINGLE pound!..Feeling More awake I was diagnosed with hashimoto's a year after my daughter was born. I thought it would be great to get on thyroid medicine and have a pill help me lose weight...no no! Since then, I have been counting calories (1300/day) and doing the Insanity beach body workout 6 days a week and have not lost one pound! (haven't gained either..but still!) This is ridiculous! I thought I was crazy when I would forget my pills for a few days and start to lose a few pounds. Then I surfed the web and saw how many people have GAINED weight! So, I decided to go off the levythyroxine until I lose 20 lbs and then I'll go back on it and maintain that weight! I did one last blood test today and haven't told my GP about my plan...but in another 3 months, I'll ask my endo to either try the brand name or the armour. I'm just bummed this will be my life-long struggle...argh F 37 3 months

 1  Levothyroxine Sodium hypothyroid I think this drug has affected my life negatively for 7 years. I have had extreme anxiety & depression, insomnia, joint & muscle pain, migraines, headaches, hearing loss, tinnitus, dizziness, neck pain, eye pain & bulging, possible TMJ, bone loss (in teeth), carpal tunnel syndrome, memory issues & brain fogginess, shortness of breath, difficulty waking in the morning, irritability, & PMDD. I take a generic - it just says "levothyroxin" on the label. I just discovered my symptoms seem to be linked to the medication. I have been to countless doctors of several specializations - and what bothers me is that not one of them linked my symptoms to the levothyroxin. I have been off it for about 72 hours and already my anxiety is almost diminished and my pain is reduced. You have to be your own advocate. From what I can see, there are numerous types of hypothyroid issues & treatments, and I plan to do my own research now. Don't rely on your doctor 100%. F 34 7 years

 1   I gain 32 pounds in the first 3 months each time the mgs are increased I gain weight. Almost everything I read on the drug it is quoted this is not true. Walk in the patience shoes of the ones of us who this has effected in this way and you will not say that. Many of us are effected by weight gain and no professional wants to take responsibility for the ones of us who HATE this side effect. F 55 5 years

 1  Hypothyroidism Anxiety (not panic), irritability w/o any cause, tremors, hair falling out, thinning eyelashes, blurred vision, tearing (dry) eyes, lump in throat, insomnia, unexplained weight loss/gain, tinnitus, itching ears, palpitations (>100 bpm), low body temp, intolerance to cold, spacey, tired, trouble talking (forming words/sentences), very active brain/thoughts (wouldn't shut down) Some of these symptoms are part of the disease.. but some resolved when I discountinued Synthroid. The mood issues, ear-issues,blurred vision and palpitations went away when I discountinued Synthroid. Now I sleep great and can drive again! These issues came back when I gave Synthroid a second chance (I thought maybe I was mistaken the first go-round). Also, just to be sure, I consulted with a professional/licensed therapist who confirmed that I was mentally healthy and didn't need therapy or mood-altering meds. I would sooner remain hypothyroid than take synthroid ever again. The Synthroid side effects were far, far worse than the hypothyroid symptoms were to tolerate. F 43 12 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

 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!!!!!!

 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

 1  evaluation of blood levels I followed the directions implicitly by taking the 50 mg on an empty stomach before breakfast. Anxiety and depression filled my day and I felt like I was wandering through a dark fog. I called my Doctor and she said that these were not normal side effects. I am thankful to have found this website because it let me know that many others have had the same problem. This was prescribed for me only because of a slight variance between my T3 and T4, and not because of any noticable low thyroid symptoms. I did not take it this morning after reading others' experiences and will not ever plan to take it again. I called the pharmacy and they did verify it was a synthetic. F 57 3 days
