Tirosint (levothyroxine) "Personally I really like Tirosint better than any other Thyroid medication I've taken. I was on Armor for 3 months and started to lose my hair and my nails got very thin. Then I switched to Synthroid hoping that my hair would stop falling out. But it only got worse. After a month on Synthroid I lost at least half my hair. So I talked to my Doctor and we switched me to Tirosint and after 3 weeks of using it my hair has barely fallen out! I personally have had no harmful side effects with Tirosint and I am glad I switched. Yes it may be a little pricey a month but its totally worth not having my hair fall out!"

Tirosint (levothyroxine) "Devastating side effects - I have developed severely crippling joint pain in both knees, debilitating nerve pain in feet after 12 weeks of taking this drug for underactive thyroid. Also experiencing muscle spasms, tremors, depression, suicidal thoughts, restlessness, some chest pains and tingling all over body. If I could have given it a lower rating, I would have."

Tirosint (levothyroxine) "I have been using Tirosint for over 8 months. I feel good and more energetic during my day. I can actually get more work done without having to take a mid day nap. However, I haven’t done blood work to see how the real effects are taking place within, but for the pass two months I starting experiencing terrible joint pains in my wrist, fingers and legs. So I’m starting to wonder base on some of the other comments if this med is cause these pains."

Synthroid (levothyroxine) "I began taking my Synthroid three weeks ago and I feel great. First I began breaking my 25 mcg pills into quarters and started out taking only a 1/4 pill. I do this in the morning with a glass of water. I am now taking one 25 mcg pill. My sleeping has improved, I have more energy, my skin looks better and my face does not look tired,. I refused to take this drug initially when I was first diagnosed in 2011 because of a bad scare taking the generic brand, so I let my new meds sit for six months before trying this brand. It works wonders for me and being a life-long gym and karate guy, I have more energy to do laps in the pool and do weights too. I have taken iodine and it works ok, but nothing like my Synthroid. Time will tell."

Synthroid (levothyroxine) "I do not notice any difference with the medicine, I’m still suffering from depression and I have extreme hair loss and weight gain even if I don’t eat more than 1500 calories a day. High protein, low carbs"

Synthroid (levothyroxine) "If you boil up balsom tea every day for one month you will cut your colestral and your thyroid down to where you dont have to take drugs. Its no quick fix but its a lot better than taking drugs. My wife is going off a lot of drugs and feels a lot better."

"Diagnosed earlier this year with hypothyroidism after symptoms. I had gained over 35 pounds in a year. I went to the doctor and they put me on Levothyroxine (25 mcg) . I have been on it a month and there is a big difference from before I started the medicine. You must wait at least 6 - 8 weeks before your body even starts to see results because it takes time! In the month that I have been taking it I have gone from 184lbs to 170lbs! I have not changed my diet or exercise routine at all. I am eating more than before (I had no urge to eat and only ate once a day) and actually have hunger pains now to eat. I also take mine at night before bed (it upset my stomach if I took it during the day) and I have more energy and not feeling bloated!!!!"

Tirosint (levothyroxine) "i've tried EVERYTHING. armour did not work for me at all. neither did levoxyl. i know people who swear by armour. i've tried generics. the generic made by abbott lab worked really well (tbey also make synthroid). while i felt better on synthroid or abbott's generic, i did not feel NORMAL. much to my surprise, i feel normal on tirosint. i have energy i haven't had for more than 15 years.... i don't know whether my thyroid will stabilize with this -- but i feel the urge to exercise which i've never had on anything else. my brain is clear and my vision is improving. blood levels were always 'normal' on everything else. but that doesn't mean it was getting cell use.... too expensive, but i can't afford to keep feeling crappy or less than.."

Tirosint (levothyroxine) "This is the best thyroid medicine I have taken. I took the generic for several years, I was constantly tired and miserable. Finally, I found Tirosint and I have been so much better. I have been on Tirosint for a year now and I am so glad to have it. I have not had any side effects."

Tirosint (levothyroxine) "I have Graves Disease & took RAI (radioactive iodine (I-31)) to treat the disease which means now I have to top up my thyroid levels. I’ve previously taken Levoxyl, Synthroid & lastly Armour. Always felt miserable with Levoxyl & Synthroid why the last three years I was taking Armour. Within the last year taking Armour I’ve had terrible inflammation/joint pain, anxiety, insomnia, hair loss, dry skin, weight gain and the list goes on. It was coincidental I forgot to take an Armour pill & realized how in one day all my symptoms went away. Next day I took my Armour and they all returned back. It was so bad I couldn’t even bend my knees. I was miserable! I’ve been reading about Tirosint the last few months and my endo was more than accommodating to let me try it. WOW!!! What a difference, I’m not as hungry, losing weight, no anxiety, sleeping through the night and overall just feeling great as I’ve never had thyroid issues. However, I did have some heart palpitation last night. I’m going to get my lab work done today, as I feel the dosage maybe too high."

Tirosint (levothyroxine) "My disabled brother was previously prescribed generic levothyroxine and brand name, Synthroid. On both, he was basically in a continual state of lethargy to the point where he would fall asleep on the commode or at the dining table. Never heard of Tirosint until requesting help. This medicine has been incredible. No more lethargy and continuous sleeping during the day. Family members have commented that he is more alert, engaged and seems to be happy. They would be correct!"

Synthroid (levothyroxine) "I took synthroid for 10 years, I had severe insomnia so also took sleeping pills everyday, I was depressed to took anti depressants everyday, had high blood pressured so took drugs for that. I couldn't focus at work and just getting up in the morning felt like a chore In 2013, I switched to natural desiccated thyroid drugs (NDT). It felt like waking up from a bad dream. I'm no longer depressed, my sleep hasn't been this good in my entire adult life. It's like night and day, I wish more doctors gave their patients the opportunity to try solutions other then synthroid; because clearly, it doesn't work for everyone."

"I have only been taking this drug for seven days after being diagnosed with hypothyroidism. This drug is awful. I honestly would not suggest it to anyone. I feel like I'm pregnant and have menopause at the same time! I'm having hot flashes, sleeping terribly, my emotions are way out of control (got really upset and in tears over something that normally wouldn't make me react that way). I feel bloated, my joints hurt worse than they did before this med, my heart is racing and I've had muscle spasms in my back and chest and legs. I've also gotten severely nauseated for multiple hours every single time I've taken it. It was so bad yesterday that I had to run to the bathroom because I thought I was going to throw up. I also feel very tired, more depressed than usual, and I have intense anxiety that is making me paranoid. Never again will I take this drug! Don't put yourself through it. It's not worth it."

Tirosint (levothyroxine) "I have to say I was excited to triosint but after roughly 8-9 weeks I started to notice tingling in my legs and left arm. I also noticed redness on my chest and vision issues. I wouldn’t have thought it was the medication but since I don’t take it one day out of the week usually every Sunday I would start to feel better by end of day once I started to take it again on Mondays my usual schedule usually by 4 hours later I started to get the tingling feeling again. My legs felt week and knees and joints were hurting. I do better on synthroid"

"I have hypothyroid but still have my thyroid. So Levo. works wells for me. Lowers my TSH and even aided in weight loss. I always have better bowel movements when taking this medication. It stopped my hair from stripping out. BUT, at first it did cause my heart to race when I was bumped up to 0.75 and it does cause fatigue. I would get really sweaty when I started taking the 0.75. I see now why they don't want you taking this if you've been experiencing heart attack symptoms because boy did this make me feel like I was having one. Only issues I had with taking 0.50 was the fatigue, but my TSH was steady going down. The side effects have subsided. Guess I just needed to stick it out. I feel better on Levothyroxine than without it. It works. Prayers for healing for us all <3"

Synthroid (levothyroxine) "For the first few years I had my OB/GYN monitoring my thyroid and adjusting my Levothyroxine… What a mistake! I never felt good and come to find out he was doing it wrong. Not doing the right test to monitor my levels and decreasing my dose when he should've been increasing. I started to see an endocrinologist and WOW! What a difference. He switched me to namebrand Synthroid only (which made a difference) and checks my levels twice a year to make sure I'm on the correct dose. I feel amazing for the first time in years!"

Synthroid (levothyroxine) "MUST be taken at night - and it absolutely seems to work for me. No more brain fog - and for someone who was always a go getter - the brain fog was devastating. No more night sweats either. Those were the worst."

Synthroid (levothyroxine) "I've been taking Synthroid since October 2010 for my underactive Thyroid and am also a type 2 Diabetic. It is now February 2011 and things are wonderful. After about two weeks, my mood improved. After 6 weeks I was able to get a haircut (prior to this my hair kept breaking off at the ends) and my hair shines again. I've also lost a total of 15.5 pounds and counting. My doctor says it's because the Synthroid has corrected my metabolism. No bad side effects to date (fingers crossed for the future too). I am on a low dose...25mg. Monday through to Friday only...Weekends off."

Synthroid (levothyroxine) "While it brought the TSH into the appropriate range, the exhaustion, lethargy, constipation, etc. was unbearable. For 20 hours out of the day, felt drowsy, unmotivated and sleepy. This is no way to live. Got on Tirosint and what a difference."

Tirosint (levothyroxine) "Great medication for those who have absorption issues (Celiac, diary intolerances, etc) and no T3 conversion problems. On that note, you will find that a specific dose of Tirosint will feel much higher than that same dose in regular Levothyroxine, for example. As a gel cap with no fillers, more medication is able to absorb into your system. Start with a much lower dose than you think you need and work your way up. Over the past 10 years I've tried Armour Thyroid, NP Thyroid, NatureThroid, Levothyroxine, & Synthroid. With all the other medications, I always felt like I was constantly increasing my dose. At one point, I was on 200mcg of levothyroxine. I'm now taking 25mcg of Tirosint 5-6 days a week. My levels have never been as "steady" as they are with Tirosint, and it's nice to know I only need a small dose of it as opposed to depending on such a large dose on a daily basis. The only downside is the price, but it makes a world of difference."

"I've been taking levothyoxine for a week and a half now and before it I would fall asleep at work, when I was driving, just watching tv. There was a time that I went through 5 different sleep medications in 2 months to try and figure out the right one because nothing was working for me. My whole body ached, and worst of all my hair was falling out. The first couple of days taking the medication my body ached really bad but it got better. I lost 12 pounds already and my hair stopped falling out. I also am able to get through the day without falling asleep and because I don't fall asleep during the day I get tired during the night! I love it."

Synthroid (levothyroxine) "Originally my doctor put me on Levothyroxine when I first had symptoms of hypothyroidism. I continue to have the symptoms and ended up putting on a total of 43 lb! I then asked to see an endocrinologist and Bug them to put me on nature thyroid.. do to my persistence they put me on 82. 75 MCG of naturethroid. After 3 weeks of it in my system, I began to have energy again, stomach aches went away, slept better and was able to work out daily again! My new endocrinologist insisted that Synthroid was better then nature thyroid... So I will switch to Synthroid.. stomach aches and fatigue came back.. Synthroid and Levothyroxine don't help."

Levoxyl (levothyroxine) "Can't find a middle ground after using this med for 2 years. (Stopping, starting, re-adjusting dosage, etc) My symptoms of hypothyroidism cross into symptoms of hyperthyroidism and I'm stuck feeling like rubbish and not knowing what to do now. (I'm 51 years old, post menopause) I'm so tired of feeling bad."

Synthroid (levothyroxine) "I was just diagnosed with hypothyroidism on the last days of October of this year.. My doctor prescribed me 50mcg levothyroxine distributed by Mylan. I was only on the medication for 3 days! The medicine made me so fatigued and tired I could hardly go through my day without wanting to pass out and go to sleep. And not only that but my chest was feeling really uncomfortable. It felt like someone had put 20 pounds on my chest and overall having difficulty taking a deep breathe. My doctor then prescribed me the brand name Synthroid with only 25mcg. I had energy like I havent had in a year, but on the third day i was having shortness of breath, my heart was beating so hard& fast &I felt so lightheaded. Seriously, scariest experience i have had."
