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)

 2  Hypothyroidism Mood swings, weight gain, tired all the time, constant need to eat I had no symptoms prior to doctor prescribing meds but had a TSH of 5 -- I had lots of energy, great metabolism, positive attitude. After taking meds, I have developed all the symptoms of hypothyroidism! I have also gained 10 pounds but have never ever had a weight problem in my life!! No matter what I do, I cannot lose these 10 pounds! My husband is taking synthroid also and has the same complaints. I forgot to take my meds the other day and felt absolutely terrific for the first time in more than a year! I think I may "forget" more often! I believe different people have different TSH levels just as they have different blood pressure and heart rates. F 49 15 months

 2  Hypothyroid Did fine at first, after three month started experiencing shortness of breath,I exercise regularly and I can't walk up the stairs in my home or talk to much with out getting winded, after another 6 months started having chest pain. Also heart palpitations the whole time, didn't realize until I started having many other symptoms,bad anxiety,so bad I couldn't handle basic things, inflammation through out my body, muscle weakness,stomach cramping,acid reflux symptoms, but didn't match the typical triggers, throat hurts and feels like there is a knot in it, fatigue, don't want to get out of bed and lack of focus. Also If I didn't eat on time, symptoms got worse. Upon taking the med in the morning, started noticing I would not feel good about an hour later and the all my symptoms would start. These side affect were worse than hypothyroid symptoms. Would go to the doctor and nothing would be found. When I asked could it be my thyroid or the meds, they said "no".Or it was something else and treat me for that, with no improvement. Had a very bad heart palp on Sun and decided to lower my does to 12.5, then off altogether.Have only been off it for a couple of days and will go to the doctor on Mon. Each day that goes by feel a little better. Any one with thyroid problems should pay close attention to how they feel and try to find a doctor that will listen.It's not just about the tsh test. I have no doubt that this drug works for others with no side effect, just not right for me. So glad to find this sight, I am not the only one. F 45 15 months

 2  Hypothyroid Was on the generic at first and I would vomit literally as soon as the pill hit my stomach and if I didn't vomit I would have really bad gas and or diarrhea. I was switched to half the lowest dose of the brand and this still gave me gas but didn't make me vomit. My dose was upped yesterday and after taking the medication as prescribed I had severe gas pain cramps and diarrhea. I work with food and this has kept me from being able to go to work now F 25 6 weeks

 2  Graves iodine trtmnt, now low th Severe depression, weight loss, heart palpitations, mood swings, loss of appetite, goiter! Hair loss, and mixed sleep patterns After the iodine treatment, they put me on synthroid. It helped after three months and although I had prickly skin feelings, and mood swings, they started me on Xanax. Not good! Waves of depression hit me and only after I go down from synthroid, the anxiety goes away and the depression lessens. When I discuss this with my doctors, they said I was bi-polar. For all these years, I can not gain weight. I am 5' 9 and weigh 115! I am now on klonopin and synthroid. My neck feels like I have a goiter. I am anxious and in a deep depression. When I cut back on synthroid, things feel better. Makes me wonder if I need it at all? F 60 25 years

 2  Autoimmune thyroiditin (Hashimotos) Burning in throat, ears ringing, no weight loss, This medication makes me feel like I'm on a roller coaster, every day is an up or down day. I don't like the fact that there is no consistency to this medication. It has helped slow the hair loss and make me less fatigued but symptoms are still present. I have yet to lose weight even with proper nutrition and exercise. F 35 1 years

 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.

 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  Hypothyroid Exhaustion, steady wt gain in spite of low appetite & frequent exercise, pains in hands, feet & outer hips, difficulty thinking clearly, obnoxiously teary. On 'max dose' for close to 40 yrs after undergoing radioactive iodine ablation. Sometimes test results would be in the low normal range of 4.0-5.5, sometimes above 6.0. Was refused higher doses because it 'might cause osteoporosis'. Have switched to Armour Thyroid - doc doesn't like it, but I'm feeling human again, & close to 90 pounds literally fell off. Not perfect, but wishing I hadn't lost almost 4 decades before finding there was an alternative. Also found there is a 'sweet spot' at the high end of the new range of .3-3.0 where I feel best, though doc is also resisting that idea. If Synthroid isn't working for you, Armour is worth a try. It's also faster acting & cheaper. F 55 38 years

 2  Low free T4 / free T3 - hypothyroid Not differences noticed at first, but gradually started experiencing suicidal thoughts, extreme sadness, etc. that wasn't there prior to Synthroid. I think it may have something to do with needing more T3. Taken first thing with water then no food for 1 hour. Also taking prometrium (progesterone) and dhea. I have thyroid-adrenal-ovarian imbalances. F 32 2 months

 2  hypothyroidism Hair loss, fatigue, heart palpitations, feel like I am having a heart attack occasionally, pain in shins, muscle and joing weakness, low sex drive, vaginal dryness, throat dryness, dry skin, eye twitching, arm muscle twitching, leg muscle twitching. Also have terrible memory problems and difficulty concentrating now. Was put on synthroid at my post-partum check up after my last child (actually was initially hyper but within a month went to hypo). I have always had problems and have never felt like it worked the way it is supposed to. My initial problems were with weight gain and dry skin and hair loss and fatigue until about 8 years ago then started having joint problems and heart palpitations. I now can't even open a bag of lettuce without using scissors. I came off of it for about 3 weeks because I ran out and was helping with tornado relief efforts. Pain in shins went away; when I got back on it pain in shins came back. I told my husband I think it is the synthroid. I am now looking for alternative treatments. I have gone to numerous doctors about my various symptoms, but they don't ever seem to find anything, actually they make me feel like I am crazy for even coming to them with these problems.

 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

 2  Hashimoto/hypothyroidism Weight gain, constipation, difficulty to concentrate, distention of stomach area, dry eyes and skin although the TSH level is now normal, as per dr (1.2), none of the symptoms have really improved. The weight gain has been steady regardless of dieting and exercise. Dr denies this is possiblethe lack of concentration is making my working life miserable, where I have to double check everything I do. Very depressed with all this. Don't know if it's the medication, the hypothyroidism or menopause. Or all of these. There has to be a way to feel better than this ? F 55 1 years

 2  Hypothyroidism Nervous,palpatations,aching knees,elbow and wrist,leg stiffness I have taken synthroid off and on now for 25 years. Starting about a year ago when I started taking synthroid again I noticed that when I sat down for any amount of time, such as 30 minutes, that I would have a hard time getting up without terrible knee weakness and hurting until I was up and walking about 2 minutes. This has now started again after being off of the synthroid most of the summer. When I don't take it after about a month or two I start to become sleepy and tired. The weight gain sets in and then I get really get upset.I must say that this merry-go-round is wearing me out. Istarted the synthroid about 3 weeks ago and my knees were killing me and my elbow too. I stopped the synthroid 3 days ago and I am feeling 75% better already. Now I realize that the synthroid is affecting my joints and I must find some natural remedies for this condition. What are my choices? Help!! Linda F 62 3 weeks

 2  hypothyroidism hair loss and muscle aches Until I started taking this medicine I had thick hair and fast growing hair. Now my hair is thinning on top and hardly grows anymore. No one in my family has had troublw with thinning hair at this age. I am 55 and this is the only medicine I take. My doctor says the dosage is correct and she says it is just a coincidence that my hair pooped out the same time my thyroid did. I don't buy that and am thinking about going off the medicine and trying alternative methods. F 55 3 days

 2  hypothyroidism hair loss , dry eyes and occasional muscle achiness Hi. I wrote before but accidentally said I've been taking this medicine 3 days instead of three years. Until I started taking this medicine I had thick hair and fast growing hair.Now my hair is thinning on top and hardly grows anymore. No one in my family has had trouble with thinning hair at this age. I am 55 and this is the only medicine I take. My doctor tells me I am on the correct dosage and she says it is just a coincidence that my hair pooped out the same time my thyroid did. I don't buy this and am thinking about going off the medicine and trying alternative methods such as diet and vitamins. F 55 3 years

 2  hypothyroidism I gained from 135 to 165 before synthroid. Of course, I was concerned. I had never been overweight that much. I was diagnosed with hypothyroidism. After taking Synthroid, I kept gaining more weight. 2007 I had kidney cancer, I had a surgery where my stomach wouldn't wake uo. I still gained weight. For some stupid reason, I put in a lap band put in. I wasn't eating that much. I couldn't eat for six weeks and gained 2 lbs. When I had a surgery go real wrong in Sep 2010, the nurse noticed after a week that I never ate that much. she told me she had patients that bloodwork showed normal but synthroid didn't stop them from gaining. That it causes fake blood reading in some people The Drs. said she didn't know anything.. I am still on synthroid because they act like they have no other drug. It's to the point that I am now 235 lbs. I stay secluded. My husband did not find me attractive overweight, We divorced for other reasons after 18 years but this problem didn't help. I look awful. They act like there is no other medication for hypothyroidism F 56 9 years
