| 5 | Thyroid disease | None | This medicine is a first-rate quality product. Its consistency factor (important to those who really do have thyroid disease) is far superior to anything else. That’s why it trumps products made before its time and gets prescribed more than any other. Plus its lack of side-effects and return of stable lab numbers show why it’s the most recommended thyroid medication out there. If you’re newly diagnosed and your doctor has prescribed it – take it (as directed). If you’re already on it – stay on it. (And don’t be fooled by the disturbing internet marketing of second-rate so-called natural products - that involves the bashing of all synthetic medications and that is conducted by those who really should be seeking other types of help...) Stay safe and be well. | F | | 4/5/2009 | 5 | None. Unless you consider that it took care of hair loss and gave me energy again. | I finally stopped feeling fatigued when I woke up in the mornings - the very first dosage I noticed the difference. I've found that you really do need to take it on an empty stomach - it makes a difference. I almost always wake up about 75 minutes before I really want to get up, so I take it then. I recently upped my dosage from 50 mcg to 75 mcg. I had noticed that my hair was again coming out more, and I had my yearly physical and blood test. Sure enough, my TSH was over the high end of 4.5 at 4.92. They recently changed the range and now anything over 4.5 means you need more. | F | 48 | 4 years | 4/17/2009 | 5 | hypothyroidism | None | Synthroid is a godsend. It cured me. It takes a few weeks to rebalance your biochemistry, so be patient. And it's very affordable. | F | 45 | 9 years | 4/30/2009 | 5 | I was born without a thryroid gland | I am overweight and have difficulty losing weight. Most of the side effects are from not taking it like I should. If I get behind on taking my pills I get severe headaches and want to sleep all of the time. | I have been on synthroid since several days after I was born when they realized that I did not have a thyroid gland. I always appreciated was the taste, because it tastes like candy. I also appreciate that with my insurance it is not extremely pricey since I have been warned by several doctors that the generics can be unstable. | F | 27 | 27 years | 6/2/2009 | 5 | hypothyroid - hashimotos | Jittery feeling. The key to this drug is to slowly introduce it into your system. It has taken me a year to work up to 75mcg a day. I felt too jittery so started with 13.5mcg! After a month or so, worked up to 25mcg and then every other day 50mcg....By noon that feeling usually wears off but it made me short tempered. Also, this is one of those drugs where generic makes a huge difference, is not at all the same. I started with generic levothyroxine and felt as if I was in a fog most of the time. Switched to brand synthroid and that completely disappeared. | This drug is absolutely necessary if your thyroid has quit functioning properly. I am no longer tired all the time, some minor hair loss stopped, skin feels better, less dry. I don't feel like I'm dragging around anymore even when I don't get enough sleep. The key is to give it time, do the dosage slowly. | F | 47 | 1 years | 6/20/2009 | 5 | Hashimotos | Emotional swings, increased libido, mostly it has helped. | I have been on synthroid for 13 years. It has helped me a lot! I stops my hair loss and fatique. I do however have trouble losing weight, high cholesterol even when diet is perfect, and recently they upped my level and now I am very irritable and you will all laugh, but my sex drive is off the charts! Husband does not complain about that! I will have to report it I guess. | F | 43 | 13 years | 7/13/2009 | 5 | hypothyroidism | None at all | I feel like a new person after starting the medication. 50mg daily--dose has been increased over the years. | F | 29 | 4 years | 7/16/2009 | 5 | Hashimoto's Disease/ Chronic Hives | None | Synthroid made me feel human again and once my thryoid was supressed my hives went into remission! | F | 31 | 5 years | 7/22/2009 | 5 | Hypothyroidism | None, although recently have experienced joint pain that has not subsided | I have been taking Synthroid or Levothyroxin (depending on which GP prescribed and what insurance I was on) for 30 years. I feel it has done its job well. I have suffered throughout the years with other issues that have similar symptoms as others described in this post such as severe fatigue which was diagnosed as hyperparathyroidism (parathyroid is different than your thyroid). Once I had the offending parathyroid removed I felt much better. I have never been heavy but I also do not lose weight when exercising regularly and watching what I eat. I am also hypoglycemic so I eat very well. | F | 47 | 30 years | 7/30/2009 | 5 | Hashimotos/Hypothyroid | Regulates my hormone levels just fine. Have had to have the dosage increased as my thyroid dysfunction increases, but no side effects from the drug itself. | If your endocrinologist prescribes Synthroid, do not let your pharmacy give you a generic or other brand. There are major differences between the various natural and synthetic thyroid brands, and generics do NOT have the same formulations as the proprietary brands. If one brand doesn't seem to be working, talk to your doctor about switching to another. But stick to a single source. | F | 45 | 4 years | 8/11/2009 | 5 | Total thyroidectomy; Hashimoto's | None, I feel very healthy :) | I had a large goiter for years but before I had my thyroid removed, I experienced weight gain, approximatly 40 pounds, hair thinning, coarse hair, brittle nails, dry skin, irratability, depression, and severe fatigue and exhaustion. After my surgery, I was put on BRAND NAME SYNTHROID, and have felt better everyday, my weight is so much more easier to control, my hair grows, I now longer have dry brittle hair or bad skin. If your taking Synthroid, or the generic, and are having bad symtoms again, I suggest getting your TSH levels read again, and going to a couple different doctors, being thyroid patients we should all know that over the years of our problems we will have to deal with changing doses, so deal! I believe in removing problematic goiters and starting fresh with taking brand name Synthroid alone, I feel like the goiter may interact with how the medicine is absorbed/used in the body. | F | 20 | 1 years | 9/3/2009 | 5 | hypothyroidism | none | I am very pleased with Synthroid. My DR had to initially increase my dosage twice, but once the right dosage for my body was found, my hypothyroid symptoms have diminished significantly. My blood work consistenly reveals normal thyroid levels now while taking Synthroid. I have been very pleased. | F | 32 | 4 years | 9/27/2009 | 5 | Hypothyroidism | None. I am very pleased with this medication. | F | 19 | 5 years | 9/11/2009 | 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 | 10/13/2009 | 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 | 10/23/2009 | 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!! | F | 38 | 19 years | 10/29/2009 | 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 | 11/5/2009 | 5 | total thyroidectomy | no side effects | My thyroid was removed due to papillary thyroid cancer.By the end of my first week on Synthroid I felt great. I have continued to experience no problems at all with this medication. In fact,I feel exactly the same way I did before my thyroidectomy. | F | 58 | 3 months | 11/18/2009 | 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 | 11/15/2009 | 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 | 12/6/2009 | 5 | Hashimoto's | None. | Feel great! I didn't even realize the mental sluggishness I was experiencing until I started taking synthroid and got my "edge" back. | F | 59 | 5 years | 12/10/2009 | 4 | Thyroid removed | My biggest side effect is hair loss | I feel better in general, still some mild flushing and feelings of anxiety from time to time. Didn't know the strange pressure in my ears could be from this drug, learn something new everyday! My biggest problem is hair lose, it wont stop and two doctors told me it's just stress related. I had very thick and healthy hair before, now it is thin and brittle. For those that have had this experience, do you have any advise? I don't want to go bald. | F | 35 | 5 years | 11/8/2009 | 4 | Hypothyroidism | ?? I have been on it for most of my life, I was 14 when diagnosed . I take 300 mcg a day. have 4 normal kids..I am 38 now. | Take your med EVERY day and in the morning before you eat.. all it does is replace thyroid hormone... The only problems are when you either don't have enough...or too much..which can be determined by a blood test. | F | 38 | 24 years | 10/1/2009 | 4 | Thyroidectomy | Overheating at night, unable to sleep, thinning of hair, irritability, fatigue, over-emotional, night terrors | When my levels are accurate, Synthroid works wonders. If I miss a few doses or if my levels are off, or if I take the generic brands, the side effects kick in. | F | 27 | 13 years | 6/16/2009 | 4 | Hypothyroidism | I experience some hair loss and general anxiety. | You know i keep asking my doctor if there could be a link between my anxiety and my thyroid meds and she is sure there isn't. I just can't imagine there being so many of us with the same problem yet no link established by the medical community. I get bloodwork done every 9 months and my numbers are normal. I distinctly remember my anxiety presenting itself shortly after i began the meds 5 years ago. It doesn't make sense to me. | F | 47 | 5 years | 9/11/2008 | 4 | low throid | I seem to be a "happier" person with it. Never had low test results but suffered from on and off again depression. It has been healthful but am worried about long term use. | F | 58 | 1 years | 8/31/2008 | 4 | hypothyroidism | very bad arrhythmia or tachycardia when it's not dosed exactly right. too much synthroid makes me feel like I am going out of my mind with anxiety, agitation, irritablity, sleeplessness, and heart palpitations. | F | 39 | 8 years | 8/26/2008 | 4 | Hypothyroidism / Hashimoto's | No side effects | I have been taking synthroid for about 6 months now. I just had my bloodwork checked again and my doc tested my antibodies this time. She diagnosed me with Hashimoto's Thyroiditis. I have heard that soy products can aggrevate the thyroid. I am vegan and regularly consume soy products. Does anyone have any information on this??? | F | 34 | 6 months | 3/17/2009 | 4 | Hypothyroidism | When TSH gets too low: fatigue, thirst, anxiety, brain fog. (I've learned these symptoms are indicators to do bloodwork.) Otherwise, I feel great! | I decided to post because toward the bottom of the page someone alleged that Synthroid was not approved by the FDA. That remark is actually a fallacy; Synthroid was approved by the FDA on July 24, 2002. You can view the approval history and other information about Synthroid. Here is the direct link to http://www.accessdata.fda.gov/ | F | 27 | | 3/31/2008 | 4 | thyroid cancer/thyroidectomy | Low energy, difficulty concentrating | After being diagnosed with papillary thyroid cancer at age 33, I had a total thyroidectomy and began taking Synthroid. My levels have been adjusted and I feel pretty good most of the time. My doctor has me take 112mcg one day and 125mcg the next because one is too little and the other too much! It is imperative that you find a doctor to listen to your symptoms instead of simply monitoring your blood levels. My endo said two important things - you must use brand over generic because generic brands are unregulated. Meaning, there could be different (slightly) levels of levothyroxine in each tablet. Those swings in dosage can really throw you off. Second, when treating cancer, it is important to keep me slightly hyperthyroid. This will keep whatever remaining thyroid cells inactive. We don't want our cancerous cells to work harder and generate more cancer cells! | F | 37 | 4 years | 2/3/2009 | 4 | total thyroidectomy, thyroid cancer | fatigue, heart palpitations | Synthroid seems to be doing its job. After my surgery, I was put on Cytomel temporarily while my endocrinologist determined if I would need RAI. On the cytomel I was shaking with heart palpitations. Also, please keep in mind, anyone is going to feel worn down right after surgery. Approx 2-4 months later, I did the switch to Synthroid, and the switch itself was exhausting (I'd be tired in the middle of the day). After a few weeks to a month of taking Synthroid, I no longer had the intense shaking, and I felt much more "level". It's been about 8 months now, and I haven't gained any weight or had noticeable visual changes. I only notice slight heart palpitations now and then (possibly due to caffene intake - no way to know). I trust my body's adjusting to the meds and will be fine in time, but I'm not at 100% yet. | F | 29 | 8 months | 1/15/2009 | 4 | Grave's disease | occasional hot flashes | This medication works great for both forms of thyroid disease. Side effects are usually moderate for the first few doses and mild thereafter. The generic levothyroxine works just as well as this drug and is much cheaper. | F | 17 | 2 years | 5/10/2008 | 4 | Hypothyroid | the synthroid made my side effects go away for a few months then they would come back. Insomnia was my side effect i always got when i went up a dose. | Synthroid makes me feel great when it is working! i felt like a new person when i first started taking it. i started on .025 and am up to .200. The longest I had my thyroid regulated was 1 year. recently my TSH was 13 so thats when my dose went up again. right now i am having insomnia but im less angry and irritated all the time and can tell the new dose is starting to help me. | F | 24 | 5 years | 4/23/2008 | 4 | Thyroid Cancer / Thyroidectomy | At onset, I experienced weight gain, hot flashes, brain fog, moments of fatigue, and headaches. Symptoms only lasted about 2 weeks then tapered. | During the past 4 years, on two separate occassions, I stopped taking synthroid on my own, only to throw my body out of synch. My cholesterol levels went up, and so did my blood pressure. When I am taking my 137 mcg daily, these symptoms subside, and my cholesterol and blood pressure levels normalize. | F | 51 | 4 years | 11/18/2008 | 4 | Hypothyroidism | Dizziness, Heart Palpitations, some confusion, At beginning of therapy, these were more severe, now less | F | 49 | 60 days | 4/14/2008 | 4 | Hypothyroidism | With synthroid, I have none. I took the generic for a while, and after a while, I ended up constipated and miserable. I had to go back to the name brand. | My only complaint is the cost. It is much cheaper to use the generic, however, it isn't worth it. I have more energy and don't feel so constipated and bloated! | F | 27 | 5 years | 4/5/2008 | 4 | hashimotos | I had increasing trouble with insomnia, heart palps, sweating after first taking the drug. I thought it was the Synthroid but it turns out that Estrogen levels are affected by increased thyroid hormone. So if you have low estradiol when you start the drug, it will just make your estradiol level even lower and give you all sorts of symptoms of peri-menopause or menopause. Once I started on sufficient estradiol supplement the insomnia, sweating, heart palps, muscle pain went away. I don't think many doctors realize the link between estradiol levels and thyroid levels... that caused me a great deal of trouble. So any ladies who have trouble when they take thyroid hormones should check and make sure they have adequate levels of estradiol before giving up on them. (like E2 of 90-100). | F | 45 | | 3/17/2008 | 4 | total thyroidectomy due to cancer | Any side effects are better than cancer..... | F | 26 | 1 months | 12/23/2007 | 4 | hypothyroidism | I have been taking synthroid since I was 13. At the time, I was very tired, cold all the time, always in a brain fog. Even though this sounds like a typical teenager..lol...my mom decided to take me to the doctor anyway. I did some blood tests and it turned out that I had hypothyroidism. No shock really, my mom and my grandma have it as well. Well, 20 years later, still on synthroid, I have started to develop strange symptoms, joint pain, extreme fatigue, etc. I went to the doctor to have my thyroid checked again. I have been taking my medication consitently for 20 years now..what could possibly be wrong?? Well, it seems that I may have Lupus! Does anyone know if this drug has a link to Lupus?? I have never had a problem with this drug but now I am wondering if it has disturbing long term effects. | F | 33 | 20 years | 12/7/2007 | 4 | thyroid | F | 59 | 6 months | 10/16/2007 | 4 | taking synthroid for hypothyroid | still extremly tired all the time no energy and i have trouble losing weight always have to work hard to lose any weight went to low carb but still strugle | not sure but cant get pregnant been trying for 4 years and seen fertility specialist cant find nothing wrong but thyroid wont stay at right level | F | 28 | 5 years | 4/27/2007 | 4 | total thyroidectomy/ thyroid cancer | Hair loss, night sweats, inability to sleep. Never had the energy I was supposed to have after my thyroid levels were evened out. | I started out taking the generic, but then my endocrinologist gave me a few months worth of samples of the name brand, and after only a few weeks the side effects disappeared. I didn't actually notice until the samples ran out and I had to get the generic refilled. Then I started noticing my hair falling out again, and I am waking up with cold sweats at night. Am switching back to the name brand this week to try and fix it. | F | 26 | 1.5 years | 11/5/2008 | 4 | Hypothyroid | Mild constipation. Maybe a little more hungry. | Only on this med a little over a week but the difference in my life is amazing. I feel more energetic, less tired. Sleeping better. Not cold. I'm told it can take six weeks or more to start feeling the full effects and I can't wait. I feel normal again after years of sluggishness and lethargy. | F | 41 | 11 days | 8/29/2007 | 4 | Hypothyroidism | Beware of taking conjugated estrogens (Prempro) for HRT as they bind with the thyroxine and counteract the effects. | Began getting sleepy all the time constant hunger and weight gain. Gained close to 100 lbs over a year and went to doc for testing. My tsh was 86.7 and doc put me on Synthroid 25mcg. Had to increase dosage over the next 5 years to 250mcg. Found out that the Prempro I was taking for HRT(both overies removed due to benign tumors) was interfering with my Synthroid. Had my Gyn reduce prempro dosage and am now feeling much more energetic and am losing weight. Have had to stay on brand name Synthroid as the generics do not have the same effectiveness for me. | F | 38 | 5 years | 6/13/2007 | 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 | 6/1/2007 | 4 | hashimoto's thyroiditis/hypothyroid | I have the normal hypothyroid symptoms. I can't say that there are any specific side effects of the meds though... I haven't really felt "normal" for 7 years since the birth of my daughter. | I know this site is to post about synthroid, but I wanted to make a comment about armour thyroid. People with autoimmune thyroiditis like hashimotos should not take armour and in fact armour will make it even harder to function as it has natural thyroid hormone in it (from pig) and when you have autoimmune thyroiditis, your body is constantly attacking the thyroid so if you are ingesting natural hormone, your body will in theory attack even harder making it difficult to aleviate the symptoms of hypothyroidism. I have heard good things about it and am sort of disapointed it didn't work for me. In my case my hormone levels completely reversed and were out of control - TSH 20+, etc. In general though I haven't ever noticed a complete reverse of my thyroid related symptoms, synthroid has helped keep my thyroid in a more regulated level (TSH 0.034) and if I have to be on it for life, so be it. | F | 31 | 7 years | 6/20/2007 | 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 | 5/10/2007 | 4 | thyroid was removed | I have had no side effects. Most of these patients should discuss how they take the medicine (empty stomach) and vitamin and food interactions will interact with the efficacy. | If you are losing your hair, maybe you should have a complete hormonal panel done. There could be other reasons for this. | F | 51 | 4 days | 7/7/2007 | 4 | hypothyroidism | When I first started taking it, I had facial flushing a couple of hours after I took it. This lasted a couple of months. I don't notice any side effects now. | I've been on synthroid or its generic equivalents for 7 1/2 years. I know what they say about not swapping manufacturers, but I have not had any unstable levels taking the generic levothyroxine (whichever manufacturer Walgreens decides to use that month). I take 150 mcg per day and have my TSH/T4 levels checked every 6 months, and they have been stable for years without any dosage changes. It's a very important medication that you will need to take forever more than likely if you have hypothyroidism. Great, necessary med for those of us that have to have it. Best to take same time every day, on an empty stomach, and without taking any other meds with it. | F | 36 | 7 years | 8/21/2007 | 4 | Hypothyroidism | None, except feeling slightly ill and losing a LOT of hair when I took the generic cheap brand I purchased in Mexico. | I have lost 85 pounds (only took 3 months to drop it) and have managed to keep it off for 4 years now. My skin isn't quite so dry, though it is still flaky in spots. my hair doesn't fall out as much and it is softer. I have a bit more energy and I digest food faster. I am not back to baseline yet, but I am well on my way. Perhaps all I need is a stronger dosage? | F | 27 | 5 years | 5/15/2005 | 4 | hypothyroidism | Really none until lately. Dr. upped my dosage from .050 mg to .088 mg.Seem to be having heart palpitations more often. Don't really know for sure if it is synthroid or my mitral valve prolapse (taking lopressor- a beta blocker - for this also). Heart palps.were rare till dosage was upped.Could the higher dosage be the problem? | F | 41 | 1 days | 5/22/2005 | 4 | hypothyroid | Can't seem to sleep w/o taking Excedrin or Tylenol PM everynight. Terrible memory. Low sex drive. | On Levothyroxine 125mcg Hair loss problems - I found drinking Brewers Yeast helps. I buy Twinlab's Super Rich Yeast Plus. No longer an issue.I've never experimented w/other Thyroid medications but know I can't survive w/o one. Feel feverishly tired without it.I'm assuming the memory and low sex drive can't be blamed on the medication but on my poor performing thryroid. If I could find a pill that fixed the insomnia,sex drive and memory loss,I'd switch. Just don't feel like going thru the search. | F | 51 | 30 years | 3/27/2005 | 4 | Hypo | Sluggishness, irritability. For the first year, I didn't experience any side effects, but since then I've been taking the generic and these side effects seem to have appeared. | I suffered for years w/ migraines but no doctor ever tested my thyroid. Then I started skipping periods. Finally, the doctor tested my thyroid and put me on Synthroid. Since then, my periods are normal and the migraines are virtually gone. | F | 37 | 2 years | 3/29/2005 | 4 | Hypothyroid | na | na | F | 31 | 8 years | 2/24/2005 | 4 | hypothyroid | pain in joints ,knees,fingers,tireness | F | 42 | 3 months | 2/4/2005 | 4 | hypothyroidism, hashimoto's | nausea, tension, anxiety | F | 17 | 3 years | 1/7/2007 | 4 | hypothyroid | reduced appetite? it's only been 3 days so that might be just a coincidence | After at least 6 years of my doctor writing off my fatigue as a one of the symptoms of depression, I finally got a doctor who did the thyroid testing I asked for. Of course, I had to twist his arm too…what is it with doctors not wanting to go beyond the basic testing? I’m only on day 3 with Synthroid, still have fatigue, but decreased appetite. Anyway, I’m looking forward to being able to get through a whole week of work without leaving early to go home and sleep. | F | 32 | 3 days | 7/17/2006 | 4 | Total thyroidectomy, thyroid cancer | Muscle aches in back and legs. Tingling in toes, fingers, legs, arms. Stiffness. Weak ankles. | I am taking 150 and it seems to work really well for me. My levels are good and I feel pretty good overall in that I have energy and little fatigue. My only complaint are the weird aches and pains I have experienced in the last few months. I don't remember feeling this way prior to taking this medication. I have been on Levothyroxine for approximately 1 year, and in the last four months I have noticed these problems. I don't know if it is a side effect from the medication, but nothing else makes sense since I am not on any other medications. I have talked to the specialist about the tingling and numbnes but he didn't have an answer for me since my levels look fine. My calcium levels were also fine, but should I take a supplement anyway? Does anyone have advise/suggestions? | F | 29 | 1 years | 5/29/2006 | 4 | hypothyroidism | The only side effects I've experienced had to do with dosage adjustments: when the dose is too high, the symptoms of hypothroidism return (hair loss, dry skin, fatigue, moodiness, cold). When the dose is too low, I get hyper, like a chihuahua. The real side effect of synthroid, as I understand it, is bone loss: something to keep in mind, surely, and try to compensate for with calcium, exercise, avoidance of carbonated drinks and other things that interfere with calcium absorption (see symptoms and tips for avoiding osteoporosis). | Synthroid is a miracle drug: within a week of being on it, I was a changed person. The toughest thing was getting the diagnosis, for it seems every doctor these days wants to be a therapist and try to find psychological reasons for your illness. The way I got a diagnosis was by figuring out what was wrong myself, and heading straight for a doctor who specialized in hypothroidism. After three years of medical "pseudo/psychotherapy, the specialist diagnosed hypothroidism in a ten minute conversation, exam, and blood test. | F | 52 | 25 years | 7/13/2006 | 4 | graves disease, radiation,hypo now | hair loss by the handful, palpitations, weight gain, listen to your body- not right, find a doctor that will LISTEN TO YOU, my doctor is great he has changed medication on my say so I finally feel close to normal after 3 years. Everybody you know should have a tsh test as part of physical before this happens to them.you can't get it right! | F | 40 | 3 days | 4/18/2006 |
