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  Hashimotos's I get out of breath more easily now and my cycle was irregular for the first time in years. It didn't help my shakiness and lightheadedness, but I've only been taking it a short time so the dosage might not be quite right yet. However, I have way more energy now than I did when I was hypo, and I feel like I can participate in and enjoy life much more. I was sleeping all the time, and now I hardly ever take a nap or feel completely exhausted like I used to. F 20 2 months

 5  Hypothroidism Very sensitive to sunlight. Nothing else that I notice. I was always cold and not terribly energenic most of my adult life. My body came to a near standstill at menopause, which is when I was diagnosed as hypothyroid. I could barely move, and had frequent heart palipatations. I thought I was dying. Synthroid saved my life. My doctors have monitored it carefully over the years and make minor dosage changes when necessary. I also monitor my diet as some foods, such as broccoli, interfere with its effectiveness. F 67 17 years

 5  Hypothyroid Energy! Feel alive! Don't want to sleep every minute of the day! Daydream about fun things instead of napping. If you are hypothyroid, there is nothing to say, it works and will change your life enormously. I used to skip class to go sleep in my car. I could and would sleep anywhere. I also had chronic headaches. There are no negative side effects for me. However, no drug is perfect all the time. To maintain my weight and boost my energy I eat a low carb diet and almost no sugar. I also take vitamins. You need to have self control to feel good when you have thyroid problems. You can't just blame everything on your condition or your medication. This drug is replacing something that your body needs to function, so I don't see any point of discussion. Just take it, inspire yourself to be well, eat healthy and enjoy your new life!!

 5  Hypothyroidism None My life is changed! I was initially hyperthyroid then swung to very low hypothyroidism and my endocrinologist prescribed 112 mcg of Synthyroid. Now my energy is back, sleep restful and deep, all bodily pains gone, no headaches, mental fog gone. I feel like I've gotten my life back and gotten 5-10 yrs younger! I'm a lifelong vegetarian and have no tolerance for prescription drugs. But this drug has saved my life and I am very grateful! F 59 7 days

 5  hypothyroidism None. I have been on Synthroid (75mcg) for one month. It seems to be great. I am starting to feel normal and losing weight. I am not freezing all of the time. I am not as fatigued as before. I still experience fatigue, but nothing like before Synthroid. My skin also isn't as dry as before and my hair is looking better. No more constipation. Mentally, I couldn't ask for anything more, but I began taking Zoloft at the same time, so I am sure that has something to do with it as well. F 44 31 days

 5  hypothroid/hashimoto's none It seems lots of people confusing symptoms with side effects here. symptoms of thyroid disorder not disappearing because of your dose or how you are taking synthroid. take in am with water (not juice milk etc), do not take with antacid, vitamins, and take at least 1 hour before eating. It makes a world of difference in how the medication works when I follow the simple instructions that the pharmacy puts on the bottle for me. A bad part about synthroid is the odd dosages. make sure your doc is looking at TSH, T4 AND T3 bloodwork and do it every 60-90 days to get a good look at ALL THREE - a Vit. D and Vit. B-12 panel cant hurt either ESP if fatigue keeps you indoors and you feel pain when touched in legs and arms. Encourage your doc to think outside the box if you seem like you are on and endless teeter totter of dosages. I take .300mcg 1 day a week and .150mcg 6 days a week. It works well and skin, hair, sleep and other symptoms aren't an issue anymore. Weight is also coming off now with about 1-3 pounds a month with minimal exercise and 5-6 pounds a month with 1 hour cardio a day. Remember it's not just up to a pill to magically cure you. You have to help yourself with this disorder; you have to be just as proactive watching your diet and excercise (no one is going to do it for you), and be proactive with your doctor and don't be afraid or feel inconveninced if you have to find a new one. It's YOUR health and YOU are in charge! F 37 15 years

 5  hypothyroid I have had a positive experience iwth Synthroid. Sometimes I have hair shedding, but I feel fortunate that it is minor side effect. I tried the generic form, however it did not work for me. My dosage has been the same since the day I started it. I was hypothyroid and had the radioactive iodine. F 56 15 years

 5  Hair Loss / Low Thyroid Loss of hair has stopped. Regrowth has started!! My labs showed I was on the verge of being Hypo. I had been losing hair for about 4 years (100+ daily just in the shower). I thought I had had my thyroid checked, but I hadn't). So I was low, but normal - and my doc thought to try Synthroid. At first I tried Levo, and for 3 days my hair stopped falling out! Then it started again :( My doc and I decided to try the name brand Synthroid and see how that went. BEST THING I HAVE DONE!!! My hair falling out is about 15 hairs in the shower now, and I feel normal. My labs are still on the low side, but in normal range. I take it in the middle of the night ( I see a great difference when taking it on an empty stomach - so when I get up to use the bathroom while sleeping I just pop my daily pill). If you have any signs of being Hypo give the NAME BRAND a try! F 37 3 months

 5  Hypothyroid I didn't experience any side effects when using a therapeutic dosage. However, if you're taking too much, it soon becomes apparent because you begin experiencing the symptoms of hyperthyroidism. For me this drug has been successful in treating my hypothyroidism. It may also be beneficial in preventing migraines, if the headaches are associated with hypothyroidism. The drug even seems to help my overall mood as well. Lastly, it seems to help my insomnia quite a bit. F 38 10 years

 5  hypothyroidism none I felt amazingly better in just two weeks of starting synthroid. I had put off starting thyroid replacement therapy for 6 months to see if my TSH would improve after an illness I had last summer. It went up considerably instead and I knew I had to start synthroid. I am only sorry I didn't start sooner. I feel so much better now that I've been taking it about 2 months. No side effects whatsoever. I am grateful to have such a good medication to use. What a difference it has made. F 57 2 months

 5  Hypothyroid No side effects. Was able to lose weight, not be so cold, and have less fatigue. ***Please** users of this site, REFRAIN from writing drug reviews if you have been on a particular drug for less than 4 months as it takes a body some time to get used to a new prescription. With thyroid issues in particular, sometimes it takes years to get the dose just right. Synthroid is doing what is it supposed to be doing for me, although my Dr. recently added Cytomel to the mix since my T3 is still low despite my taking 200 mcg of Synthroid. Cytomel has given me much more energy and improved my hypo-induced depression, not to mention added extra zing to the weight loss. Cytomel is a wonder drug --look it up. F 41 8 years

 5  thyroid not working properly None at all and I am one to have them it seems so I am very happy and surprised. Another plus is that it is inexpensive. I do recommend the brand name and not the generic though. I wasn't happy with it and my energy level dropped. I pay for the Brand name and it is about the same as my co-pay! F 56 4 years

 5  Hypothyroidism Nearly all the "side effects" I see listed are actually caused by the thyroid problem itself. I have been taking synthroid for nearly 20 years. My family has a history of thyroid problems dating back for at least a century. Thyroid problems can cause issues ranging from dry skin and constipation to fatigue and weight gain when your thyroid is low to jitters, goiters and heart palpitations when the thyroid is high. It takes a while for thyroid medicine to fully kick in and then you have to closely monitor yourself and get a followup blood test to see if you are at the right level. If you feel "off," it's likely that your does is not correct. I also have found that I don't feel as well when my thyroid numbers are a low normal as opposed to an average normal. Doctors should move through dosage levels slowly. It can be dangerous to have an overactive thyroid. It is particularly important to watch your thyroid levels when pregnant. We have had miscarriages in my families when the thyroid dose was not monitored or an individual did not consistently take her thyroid medicine F 37

 5  Hypo - diagnosed with a TSH 7 None that I'm aware of(at this point)- but will be watching - I do wonder about the weight issue. By the time I was diagnosed (approx 9 months ago)- I had dermatitis, weight gain (& hard to lose weight), depression, dry skin, hair thining, face skin deteriating, sensitive to cold, sever fatigue, muscle/joint aches, increased cholesterol levels and memory loss (I was a mess - and classic for Hypo-Thyroid). The Synthroid dose has been adjusted over time - I'm currently at a dose of .100 - TSH .91 (stared with dose of .5 - TSH 7). The Synthroid has helped me GREATLY. I do hope that it continues to remedy my symptoms. But like all substances that we ingest - some work and some don't dependent upon our own individual physiology. Right now I'm happy with it.
