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  Hypothroid None I have been taking synthroid for 10 years and I have had no issues that I know of from it. It appears to be working for me and as long as I know it keeps me at the right levels I will keep on taking it! F 36 10 years

 5  Hypothyroidism Nothing Yeah I have hair loss, but I had that before the Synthroid. It is a symptom of hypothyroidism. And for you that are complaining of weight gain...what are you eating and what was your weight like before? I've been more successful on my weight loss since starting the Synthroid. For the past 5 years I had went from 90lb to 230lb. I ate extremely healthy and still gained weight, as soon as my levels were regulated I started to see weight loss...I feel better than ever. I was on synthroid for 3 days and my heart palpations stopped. I feel like living now and I owe it all to Synthroid! F 31 4 months

 4  hypothroidism I was shaky,jumpy, tired, and spaced out for the first week and occasionaly when levels are too high or low. Heavyness when swallowing (from thyroid being enlarged) especially when lying flat. I found out about my throid after I got a goiter. I was 22 and just had my first child. I gained about 70lbs. during the pregnancy. I went on synthroid. I lost all the weight I had gained. With my second child I only gained 28lbs. When I feel different (extremely tired, grouchy, spaced, or consitpated) I call the doctor and have them get an order for blood tests. Occasionally my throid goes hyper then back to hypo. It's my body and I know when something is off. Blood work will become second nature to you every 3 to 6 months I get tested. When my levels are correct I feel great! Don't let the doctors call the shots we pay them! F 30 7 years

 1  Hypothyroidism acid reflux, tired, weight gain, mis-carriages, not unable to concieve I absolutely am against Synthroid. I am on .075 and my levels are normal. I got diagnosed w/ Hypothyroidism after I had my son in 2002. I have since tried to get pregnant and lost a baby right around 7 weeks, 4 months later, we concieved again and lost a baby again, around 7 weeks. I have never had any type of infertility problems. Not until I began taking this medication. I have gained 40 lbs in the past 3 years and I have intense acid reflux. I get the reflux after taking the medication so I know that is what is causing it. My Dr's, pcp, obgyn and EN all say it is better to keep taking the medicine for birth defect reasons, however, I can't even seem to get pregnant now. I have been on clomid 5 months so there is no way I am missing the time to concieve. Prior to taking this medicine, I have not had health problems like I do now. I began at .025 and it was normal, over a period of time, it has now went up to .075 so I am thinking the Synthroid actually messes up the thyroid, even tho F 31 5 years

 1  hypothyroidism I am reposting. I posted 3 posts down. I want to add that when I started out on this medication, I did not feel the negative side effects right away. These started to appear slowly over 3 1/2 years. The longer you take this stuff the more chance you will destroy your thyroid gland and then become dependent on it for the rest of your life. I am now skipping every other day and am only feeling better. I don't have the detached/disconnected feeling anymore, I am feeling like my old self again. I admit, anyone who has had their thyroid removed or destroyed needs to be very careful with their meds, but in my case my thyroid was functioning and it was probably a grave mistake to get on the meds. Think for yourself. Why put all of your trust in an industry that profits from your sickness?? I will keep ya'll posted on my progress :) F 38 3 days

 5  Hypothyroid Side Effects? What are those? :)I can only see positives. Usually I come to this site to see what others think of a drug before I start taking it, I never like walking blind into anything but goodness seeing all the negatives and the this is poison comments makes me wonder why I stop here so I decided to post for all of those like me who may stop by just because they are interested in what others think. First off stopping any medication without doctor approval is very dangerous especially when it's something that is dealing with your hormones! If something doesn't make you feel right you should talk to your doctor alot of times our minds play tricks on us and convince us that it's the medications we take that are causing the side effects when 9 times out of 10 it sounds like anxiety and not the drugs from all I've read. I personally think Synthroid is wonderful of course this is only the beginning of my 3 week of taking it but I feel better than I have in years!!! I actually have energy to do things, the soreness and stiffness I alway F 33 2 weeks

 1  Synthroid i am a 38 year old female been on this for about 3 1/2 years for mild Hypothyroid. It started with hair loss, then goiter appeared, arthritis in hands. TOTAL loss of libido/sex drive. Chest pain followed, then bone/muscle aches, kidney infections, finally mental confusion, depression and short term memory problems. Thank God I did not let them destroy my thyroid. The highest dose I was on was 1. I am angry that the dangers and side effects of this medicine were not made clear to me. I made the decision to get off medication. I am currently weaning myself off of this horrible medicine. I started to cut my 1. pills in half so I have been taking .50 for the past 2 weeks. I have also added a multi vitimin, 1000 mg Vitimin C and Selenium daily to help promote my thyroid to pick up again. Beginning today, I plan on skipping every other day of medication, and closely monitor how I feel. So far...I feel sooo much better!! All of my symptoms are gone!! Today I actually felt my libido come back, which is what prompted me to post. I am soo happy to actually FEEL again!! The only negative thing I have noticed is a very very slight weight gain in the rib area over a couple of days....but that seems to have tapered off. I will come back to post in a couple of weeks. I am soooo starting to be me again. F 38 3 days

 2  hypothyroid I started on it to treat depression and fatigue.It just didn't seem to have any positive effects.The depression lifted only after starting antidepressants,and I still have some fatigue. Gained nearly 20 lbs, which was distressing because I have always been on the thin side.Tried different exercise routines without losing a pound.I eat very healthfully.I decided to go off it 3 weeks ago because it never helped in the first place.My doctor was totally adament about it not causing wt.gain,but reading this I wonder how they can say that??? Does anyone have any experience with virgin coconut oil?It claims to help thyroid function, boost energy & metabolism. F 28 18 months

 3   I would like to respond to the patient who has been taking Armour for 3 months. I have taken Armour for 14 years and I know what I am talking about! Armour company does not slaughter pigs, they slaughter cows. The medicine is NOT approved by the FDA and any endocrynologist will tell you so. It is unreliable dosagewise, it is dessicated cow thyroid then pounded into pill form. Each dose differs slightly from the previous dose. Our thyroid glands do not produce the same type of thyroxine that cows produce. Three months is not enough time for anyone to express their opinion about the efficacy of any medication. One can barely have their dose adjusted in such a short period of time. F 51 14 years

 1  Hypothyroidism No resolution of disease: continued fatigue, hair loss, osteo, muscle aches, brain fog. While Synthroid may work for some-it did not work for me. Naturethroid (just like Armour), along with adrenal support, has resolved my symptoms. Please read the article on Desiccated Thyroid Extract at Wikipedia.org for the full details on thyroid treatment, and the discussion article as well. Armour has not contained any cow (it formerly was a beef/pork mixture) for more than 30 years. It is easily available by prescription at any pharmacy (see Drugstore.com). Doctors cannot prescribe unapproved drugs or they would lose their licenses, as would pharmacies. It is the pharma reps. who tell these untruths about competing drugs in order to boost business and, most unfortunately, the reps. are often the only source of info. for doctors who pass this on unwittingly to patients. Patients: please do your research and make informed opinions. You have nothing without your health! (my last post here)... F 52 3 months

 1  hypothyroidism No relief of hypothyroid symptoms. I feel I must respond to the comments of the person below me regarding Armour natural thyroid medication because there are so many falsehoods presented which are patently misleading. First of all, Armour is natural thyroid from pigs, not cows, and has a 100-year record of efficacy and is definitely approved by the FDA. This can be checked via Google. Armour is also properly compounded and tested for dosage and is prescribed by the 1/4 grain and upward. Armour also replaces T3 as well as T4 (and T1 & T2); Synthroid is synthetic and replaces only T4. Is is possible the symptoms the prior rater experienced were the result of weak adrenals. Please see the thyroid reporting by Mary Shomon on About.com and Stopthethyroidmadness.com for further information. F 52 3 months

 4  goiter When I took Armour for 14 years, 180 mg, I got osteopenia (pre-osteoporosis) at 35. My heart was fluttering, I was very thin, PVC (preventricular contractions), MVP (mitral valve prolapse), leg tingling, dry skin, loss of hair, insomnia, hot and moist hands and skin in general, severe calcium leeching from bones. Armouris NOT approved by the FDA, do not take it, it is dessicated cow hormone, pounded into a pill form, uneven dosage. When I switched to Synthroid I got my energy back, my bones thickened again, no more osteopenia, no more back pain, headaches, etc. It took about a month to come down from such a high dose of cow hormone (180 mg) to 112 mcg of Synthroid and there were some unpleasant sideeffects. But they went away. I lose hair all the time but it grows back. I am 30 pounds fatter, with no change in diet or activity level, but I would rather be fat than osteoporotic and dead of a heartattack. I have been on Synthroid (various levels) for 10 years. I am now on 112 mcg and my symptoms have stabilized. Do go to an endocrynologist since regular physicians are not trained to treat thyroid problems. F 51 10 years

 4  Hypothyroidism Its unclear to me, but a while after taking the drug I developed some Tinuitis. I am a chronic sinus suffer so it very easily could be coincendence. HOWEVER, this drug is messing with your hormones so expect some changes no matter what. DO NOT let your physician make large jumps in dosage. You very well may need to try a few different doses, stick it out because in the long run you will get your body back in sync. Again, you are messing with hormones so listen to your body. My dosage was moved to fast one time and I became VERY irritable. If that happens, go down a dosage and remain there for a while. Prior to be diagnosed with hypothyroidism it was never clear to me why I always felt tired and irritable. After starting treatment and reaching the correct dose my life was COMPLETELY different. I am now a MUCH happier person and had forgotten what it felt like to energetic. Generally your hormones do not fall out of whack overnight. Thyroid conditions worsen over a long period of time so it can be hard to notice the affects until its really bad. My life is 100% better after getting on this drug. I use the generic form with good results. I would recommend seeing a specialist during the intial phases of starting. Internal medicine doctors try, but they seem to always get the dosages wrong. Once you are stable and on the drug internal medicine docs should be able to do the yearly tweaking. M 33 5 years
