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)

 3  Thyroidectomy (cancer) Currently taking 175mg synthroid. Still have fatigue and heart palpitations. Freezing at bed time and then night sweats. I am thinking about adding iodine suppliments to help this. Moodiness. Weight gain. I had no problems having two pregnancies and two healty children since the thyroidectomy 5 years ago. Dizziness comes and goes. Very stiff neck and jaw. Memory loss/ lack of concentration and focus. So much water retention that I had my wedding band CUT off. Stiff joints. Be very selective when choosing your docotr. ALWAYS see a specialist for your testing and resluts. After my second baby, the OB prescribed synthroid at 125mg. I knew this was too low for me. In 3 months she tested my blood and took me down to 100mg synthroid. I was too tired to even chase that rabbit! And about eight weeks later my body SHUT DOWN! I sat in the chair and just cried from exhaustion. I felt like was taking in enough fuel through food, and getting what seemed like the proper amount of sleep, but I couldn't move. That was about 5 months ago. At that point I went back to a specialist and decided to go to 175 mg daily instead of 150 mg and 175 mg wevery other day. Yeah, I wish there was a perfect answer. I hope the natural stuff that is out there works. It seems like the research is not plentiful yet. F 35 5 years

 1  Hashi/Low thyroid Headaches, weight gain (30lbs) although no exercise or eating changed at all, cold, irratible, heavy and long periods, hair loss, eyebrow loss, acne, dry skin, joint and muscle pain, feet hurt, itching, and on, and on. 100mcg Synthroid made all this worse than ever. Horrible drug. Recently found a doctor to switch me (4docs later)to Armour or natural. I can't believe I'm am getting back life now. No headaches at all, not cold anymore, eyebrows growing back, acne cleared up, memory is almost genius (JK), vision improvements and even started to loose weight with no changes. Please look/try natural thyroid 1st. My marriage/life saver F 41 1 years

 5  goiter thirty years ago hard to tell...seems to have positive effect when taken faithfully of keeping energy and temprament at steady keel even through menapause not sure I ever needed this drug - not automatically given for goiters today - but don't think I experienced side effects that I ever noted...thought taking it regularly may have helped keep weight and energy level in check, but have been lowering dosage and not feeling the loss of it even after 33 years! I think folks should take it if it's recommended. It's been used for so long. But the generic versions should be avoided. That's for sure. Not sure why, but when I took generic version, I felt for the first time like someone with an out of whack thyroid. F 62 35 years

 5  Hypo after Radiation for Grave's Muscle cramping, localized joint pain, hair loss and weight gain. I was on synthroid for about 7 years before the birth of the children, and then stopped taking the meds without a Dr's consultation and since then I became severly Hyper (5 times the normal acceptable level) and was loosing weight and hair like crazy and couldn't sleep. I had the radiation treatment and am now hypo as I was told would happen. We are still trying to find the right level for me (.1mg currently) but now I can sleep! I have gained back the weight and then some and that doesn't bother me at all. My main concern now is the terrible hip joint pain. I will be requesting testing for arthritis in the week to come. If you feel you aren't being heard by your Dr...find someone else. You need to feel comfortable with him/her and they NEED to listen to you and not shrug off your concerns. A great Dr makes a world of difference. I am not seeing a specialist, just my regular GP. If you are having problems on synthroid, do some research, get informed and take control...your Dr F 34 2 months

 3  Hypothyroidism / Hashimotos Tired, run down, mind in a blur, weakness, overall fatigue Overall this has helped me feel better, though I don't feel totally better yet. I am sure with a better diet and more exercise I'd feel better, but I still don't have enough energy to do that. F 29 5 years

 1  Hashimoto's Very, very tired, rashes/hives/itching, dry eyes, felt unbalanced and clumsy, headaches, longer heavier periods, bad nails, dry skin, bad acne, hair loss, and very cold now. All these got worse after Synthroid. This is the worst drug ever, I wish I knew more about Amour, Nature-throid and the natual ones that included T3, T2, T1 and other things our bodies use. On 3rd doctor and none will change me over. F 40 6 months

 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

 1  Hypothyroidism My side effect was that I experienced nothing on Synthroid. I didn't feel any better, and my blood work/labs didn't get any better. For me, Synthoid is not the right thing. It is synthetic hormone and only contains T-4. The healthy thyroid produced T-4, T-3, T-2, T-1 and Calcitonin (which protects the bones). After synthroid, I asked my doctor for natural dessicated thyroid (Armour Thyroid) and have been using that for about 15 months. My brain fog has lifted, I have stopped losing hair, and I'm getting my energy back -- I can now work out 30 minutes 4 times a week!. I'm not quite optomized on my dosage, but my labs are getting better; and I have hope that I will continue to get better. F 52 3 months

 1  Apparently Hypothyroid I am so confused by this medication. Apparently I have a "sluggish" thyroid that I never knew I had. So, I took this medication because it was supposed to "speed up" my metabolism. I don't feel I'm overweight and have been athletic all my life. I took it thinking I would feel better, even though I never felt bad to begin with. The doctors convinced me I felt bad? Anyway, I started the medication and gained 15 lbs. in one month. NO lie. I just went off of it. Will never take another hormone. Terrible drug for me. I don't understand how people do well on it. F 1 months

 1  hypothyroidism no new ones, but the effects of hypo were not relieved. I had a slight improvement, but never felt 'good' or 'normal.' I also continued to gain weight despite being told my thyroid levels were normal. I switched to natural thyroid and have felt GREAT for about 3 years now, after 3 years of feeling lousy on synthroid. natural thyroid is so much better! I regained my life and my normal metabolism ONLY after switching to armour thyroid. synthetics just don't do the job. F 43 3 years

 1  Hashimoto's thyroiditis I had near-constant migraines while taking this drug. I was also exhausted, with flu-like symptoms that persisted the entire time I was on the drug, and went away as soon as I stopped. I switched to Armour thyroid and am great! F 37 4 months

 1  hypothyroid Synthroid did NOTHING for me, even though I kept tweaking and tweaking it. I have NEVER, EVER met anyone who got rid of all their hypo symptoms on Synthroid or any other T4-only meds. I don't doubt the positive testimonies here, but I can guarantee you that you would have MUCH better results on natural dessicated thyroid like Armour rather than a T4-only med. It's T4-only. The thyroid makes T4, T3, T2, T1 and calcitonin. I switched to a med that contains ALL of those, and the difference was WONDERFUL. F 17 years

 5  I lost my thyroid due to mercury No side effects for now. I've been on it for about six months. I'm imagining my knees getting weaker because of what I've read with regard to bone loss. The best "side effect" however is that I have energy again! I could not imagine living without Syntrhroid - and I hate drugs!!! I was a middle age Father of five who ran 15 -20 miles a week. For two years no one could figure out what was wrong with me. It took me forever to wake up and get moving in the morning. I was down to running two miles at a time and being exhausted. After taking Synthroid for two days I ran five miles straight for the first time in two years - with tears in my eyes! I was dead without it - so I'll just pay the piper for whatever long term side effects may exist. By the way, the most amazing detail of my having to be on Synthroid is that my own immune system attacked my Thyroid and devored it because of the level of Mercury that was in my thyroid. If I didn't live through it I would have found it hard to believe myself. I had an extremely high level of mercury in my system due to replacing nine mercury fillings. I was gaining weight and blowing up (quite literraly and figuratively). I went to the best doctor's out there and they were clueless. My wife (who is a Physician Assist M 52 6 months

 5  lost my thyroid I don't know why my message was cut off so I'm adding what got deleted. Read my "second" message first! My wife (who is a Physician Assistant) just ran my blood one time and saw that I was hypo thyroid. A simple Google search (thyroid mercury) did the rest. Trust me - the experience was quite a character builder! It is by the grace of G-d that my life is back to normal. I played in the snow today with my four year old daughter and just thanked God for every second! Most Doctors are just too pressed for time and are trained to treat symptoms - and not trianed to "listen" to a patient. Anyway, good luck to anyone reading this! M 52 6 months

 3  Hypothyroidism When I feel that I have too much of this drug in my system the following things happened:rapid heart beat, dizziness, vomitting,couldn't get out of bed, high blood pressure, nervousness, tremours. I started taking synthroid about 8months and struggled to get my thyroid counts to stop bouncing all over the place. September 2005 my doc calls and tells me I have gone hyperthyroid and to stop all meds immediately, so I did. He called in October 2005 and told me that my thyroid had gone very low and to start the synthroid immedicately at my old dose .075. I did and 30 days later I felt like I was dying, doctors told me it was anxiey-NOT!!! I feel that I was on too much of synthroid. My doctor thought maybe it was a side effect of synthroid, he put me on Eltroxin, things settled down, heart rate lessened but would go away. Blood test showed 10.8 tsh five days later shower 3.81. Still shaky so I lessen my does to .05 and after three days the heart rate is barely noticable and I am starting to come out of my fog. I am going to see a Endrocologist soon and I have lots of questions. I am still researching but I know my body better then anyone and when my doctor said not to lessen F 34 8 months

 2  Hypothyroidism Heart paplpitations, tremor, nervousness, missed periods, allergies,mood swings,joint and muscle pain I have finally come to the conclusion that doctor's must hear complaints about the side effects of this medication on a regualr basis. My doctor said, well, you have these tremors but that's better than feeling tired all of the time. I hated that he talked to me like this is it - just accept how you feel even though you don't feel good. I am going to try switching to Armour after feeling horrible for almost two years. I should note that I took this medication for a year with no problems and only experienced these symtoms after the birth of my son - I guess my body chemistry changed and is now not tolerating the medication well.
