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 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

 5  Hypothyroidism / Hashimoto Disease Felt terrible during the first 2 to 3 weeks and slowly regained energy and overall health. Started with lots of dissapointment, however I think otherwise now. I am very satisfied with Synthroid and want to share my experience with anyone that is at a loss about it as when I started 3 months ago. I was very skeptical since I have been a pretty healthy person and never thought I would need to start taking a LIFETIME medicine @ 38! Once I started taking Synthroid I felt extremely nervous, dizzy, nauseous, bloated and my stomach acting up during 2 to 3 weeks. I Almost quit several times, since I felt worst than prior to taking Synthroid. However, the side effects slowly but surely disappeared. I stopped feeling exceptionally tired, depressed, introverted and always cold and started feeling happier, energetic, and benefited from a great digestive system again... After 3 months I am exactly weighing the same as before taking Synthroid. Sure I exercise some, but I definitely don’t kill myself, and all I do is take care of myself using common sense. I drink lots of water. Don’t give up on this synthetic hormone called Synthoid, because there are millions of people taking it all over the world (by the way I am originally from Switzerland) and before telling you F 38 3 months

 5  hypothyroid none. I have used Synthroid for years and have been very satisfied. I can tell when I need an increase in medication. I get tired, start to gain weight and hair coming out more. I go to my doc and get bloodwork done. One time years ago I did this and my doctor said my levels were fine and he wouldn't increase my Synthroid, but I knew how I felt. I switched doctors and told my new doctor how I felt. She agreed to increase my Synthroid but wanted me back in six weeks to make sure we didn't over do it, which would cause other problems. The increase helped and I learned that if my levels are in the middle of the normal range, then I don't feel good. But if I am in the high normal range, I am fine. Everyone is different and if you've suffered hypothyroidism, you know your own body and its signals. Find a doctor that will listen to you and work with you. My doctor knows I need enough meds to stay in the high normal range in order to feel good. F 41 15 years

 5  Hypothyroidism Initially, my heartbeat felt a little weird (for about a week), afterwards, it went back to normal Within 3 days, I started to see some improvement in my fatigue; after about 6 weeks, I could really feel the difference in my energy level; I'm "moving" more, doing all the things I liked to do before the hypothyroidism kicked in; I have more energy to enjoy my child and I've even lost a few pounds (because I'm not so tired and sleepy all the time, I enjoy being outside more; my quality of life has improved; I'm happier because I'm feeling better ....not to mention that the size of my thyroid gland has decreased (don't think it'll ever return to normal size because it was enlarged for a prolonged period of time) A WORD OF ADVICE (some of which is on the drug information leaflet): Try to take the dose AS SOON AS you wake up in the morning with AT LEAST 8 ounces of water ON AN EMPTY STOMACH; don't eat for at least 45 minutes and DO NOT TAKE ANTACIDS within 5 hours before or after F 40 60 days

 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 No bad side effects. If feeling better is a side effect, bring it on! Initially was diagnosed with hypothyroidism in 1999, after four years of being treated for a lot of different things; depression, chronic pain, post traumatic stress. WHen a doctor finally listened to me and put together all of my symptoms, I was diagnosed with extreme hypothryoidism. I eventually got enlarged nodules, but after finally getting my dosage right, my hypo is under control. I will probably never lose all of this weight, but that is a minor complaint for me. I always weighed less than 110 pounds until 1994. I started gaining and was 168 at my largest. I am now 160. My endochronologist treats symptoms, not numbers. In order to stay symptom free I have to keep my numbers below the normal. I am checked every six months with blood work and a complete exam. He watches for dry skin, growth in the nodules and other symptoms. He adjusts when necessary. F 49 7 years

 5  clinical hypothyroid diagnosis None. I felt MUCH better after only a few days. I had all the symptoms of hypothyroidism but could not get any doctor to diagnose me for several months. I felt so bad that I spent my days lying around. It wore me out to was dishes. Finally found a doctor online who knew alot about thyroid and did not dismiss thyroid problems because of normal blood work. She knew just by talking with me and examination that I was hypothyroid. I know that GOD led me to her. Don't be satisfied until you get the help you need. F 22 39 days

 5  levoxyl waking up in the middle of the night. I have been on this med. for 1 week and I already feel so much better....energy is a big plus. I was practically lethargic before finding out my t-4 was low. I was on Armour before for 2 months and felt no difference...still tired and ate like crazy. I'm so glad I was put on the levoxyl. F 39 8 days

 5  Hashimoto's disease (hypothyroid) None. However, I am only 52 and have osteoporosis. Because the dosage of this medicine has to be carefully monitored, there have been periods of time when I have been taking too much synthroid, before I realize it through bloodwork. This may be a contributor to the relatively early appearance of osteoporosis. I was shocked to read that people are taking Armour Thyroid. Are they aware that this medicine is derived from pig's thyroid glands?(it says on the website "porcine" for the source) This is what physicians used to use before synthetic thyroid was invented. Its great downfall is that it is much more difficult to create accurate dosages of the medicine because the amount of thyroxine may vary from animal to animal. I tried this when I was first diagnosed with hypothyroidism in my mid 20s and I felt much better when I switched to synthroid. F 52 26 years

 5  Hashimoto's disease/hypothyroid Took a few months and a trip to endocrinologist to get right dose. Found out I have to wait 12 hours after taking synthroid before taking any mineral supplements (calcium, iron, magnesium)or fiber supplements. Before that, I was taking the supplements too close and blocking the synthroid!!!! Also, found out I need to avoid soy-- if I eat it (and it is in a LOT of foods) soy blocks the effectiveness of synthroid It's been a few months since I started synthroid. Dose had to be upped a few times. Went through extreme fatigue, hair loss, and neck and muscle pain before getting to the correct dose which is making a WORLD of difference in how I feel. My sense of smell is returning now, at 75 mcg synthroid. Also, I do not have constant muscle pain. Have been diagnosed with fibromyalgia in past but now on synthroid, that pain is leaving. Also, had major depression but on synthroid that is improving immensely, too. I did not experience these radical improvements until I got on the correct amt of synthroid and stopped taking vitamins/minerals/iron too close to medication. Avoiding soy is making a huge difference also. My new endo is willing to give me Cytomel if this dose synthroid doesn't help me enough. Will be going back in a couple of mo. F 52 8 months

 5  Hypothyroidism Zero side effects, except feeling great and feeling full after eating. Have lost weight without trying, especially the trouble zone (tummy) which I gained in the 2 years I've complained about symptoms. Told my doc for 2 years I've had problems, treating everything but Thyroid because it never showed in blood work until 2 years later. Hair had been falling out in clumps. Finally, test showed positive. Been on Synthroid for 2 weeks and I feel great! Guess it works for some and not others. I'm on a low dose of .75. F 43 14 days

 5  hypothyroidism none Really helpful for years; I can tell in a few hours when I miss a dose. Several people have warned others away from Synthroid. Clearly people's body chemistry differs - whether it works well or poorly for one person doesn't really say much about how it will affect someone else. You'd have to do a large clinical trial to get any useful results. F 54 10 years

 5  Hashimoto's Disease None Be careful of the (generic). I lost my hair, experienced flu like symptons, and had severe lethargic episodes. Back on name brand, no side effects and my hair is comming back! F 44 16 years

 5  hypothyroid none I was constantly cold, constipated, tired, had dry skin and brittle hair until diagnosed as hypothyroid and put on Synthroid. I hate drugs, but this natural occurring hormone we all need to have a healthy metabolism. It works! I am healthy and active; all negative symptoms are gone. Been very happy with Synthroid since 1991. F 48 13 years

 5  hypothyroidism none, of course, I've been on this medication since I was 3 days old works like a wonder, when I don't forget to take it. When I do, my thyroid gland enlarges, and hurts like hell. But when I do take it, my body feels normal and I don't feel sick. F 23 23 years
