For Underactive Thyroid "In November 2020, I was diagnosed with low thyroid. My doctor put me on levothyroxine 25 mcg. I also went to Walmart and they gave me Euthyrox. I started taking it on the 11th. After taking it for one week, I began having hip pains that radiated into my legs. My joints ached and burned. I had headaches, low energy, dizziness, confusion, and a foggy brain. I didn't want to move as it hurt. I am a retired nurse and knew the recent change was due to medication. I stopped taking it on the 19th of November. I went to the doctor's office and was told to stop taking it. By Thanksgiving, I was feeling better. It took a few weeks to feel normal again. I have been prescribed Synthroid today and going to try it. It is the brand name of levothyroxine. Hopefully, I can use it. They need to inform people about how dangerous this medication is. I will stop using Walmart. They told me I was sick with a virus and treated me like I was delusional or making it up. I hope they never experience the same as I did."

For Underactive Thyroid "Began taking in early June when Walmart pharmacy refilled my prescription, saying Euthyrox was their new generic and what I would be getting going forward. Within days of taking the first pill, I began to experience headaches that progressively increased in duration and frequency during the four months of taking Euthyrox. Then began the insomnia, tinnitus, heat intolerance, uncontrollable sweating, swelling in the face and eyelids, diarrhea, neck and shoulder pain, blurred vision, fatigue, occasional dizziness, dry mouth, loss of appetite, and brain fog. Stopped Euthyrox almost two weeks ago, and most symptoms have gone away except for headaches and neck pain. Definitely returning to the prior medication, this one was disabling."

For Hypothyroidism, After Thyroid Removal "Walmart switched me to this brand back in April. They assured me it was the exact same thing as the levothyroxine brand I was taking. I had just had labs done in March. Things were good. By early May my TSH had jumped to a 14 from a 0.40. I had fatigue to the point that I was bed-bound. Headaches, sleeplessness, rapid heart rate, sweats, memory issues. This medicine is a dangerous medication. My doctor had several other thyroid patients complain of the same medication after Walmart switched them. It is absolutely not the same as what I was taking. This medication will crash your labs and make you feel like the walking dead. It shouldn't be on the market."

For Hashimoto's disease "This drug has many side effects that I am experiencing: labored breathing, hair loss, blurred vision, fatigue, chest pain, heart skipping beats, nausea, and insomnia. I was taking a little oblong yellow levothyroxine that worked great, but the drug store changed companies, and this pill is round and white."

For Hashimoto's disease "Started this Euthyrox about a month ago after Walmart switched me to it. Since then, I’m having daily headaches, sometimes migraines, more hair loss, and fatigue. Called Walmart, and they switched me back to my previous manufacturer with no problem. This brand didn’t work for me."

For Hashimoto's disease "I have had Hashimoto's for 8 years. Tried Levoxyl, Synthroid, Armour thyroid. Finally went to generic since they all seemed about the same and the cost was far less. I felt great, very stable TSH, etc. Walmart switched to Euthrox with my last refill, and I feel absolutely horrible. Low energy, weight gain, complete brain fog, and many, many more. Since it was a new med, I alternated it every other day with my old generic and this. Felt okay, so I switched to Euthrox daily and honestly feel as if I am taking NOTHING. Glad to hear it seems to be an almost universal complaint. I plan on visiting Walmart tomorrow to see if there is anything they can do about replacing this horrible medication."

For Hashimoto's disease "I was switched from my normal levothyroxine to Euthyrox recently because Walmart pharmacy switched me (without asking me). I was told the blister pack was a better option because it maintains the freshness of the medication, which is supposed to make it work “better.” My TSH typically sits around .9-1.2, and now I’m at 3.69 as of last week. The only thing that has changed is my medication! I’ve felt terrible - very cold, lots of crushing headaches again, joint pain, fatigue... I’m afraid it’s from switching over to this med. I’m calling my endocrinologist to try and move my rx to a different pharmacy to see if I can get off the Euthyrox."

For Underactive Thyroid "Oh my gosh. I am so pissed after reading all this. I have been on a physical roller coaster for almost a year now. Last May, unbeknownst to me, Walmart switched me to Euthyrox from my regular levothyroxine medication, Synthroid. When questioned, I was told it was the same. Fast forward a short time, I can't get out of bed. I can't even think or carry on a conversation, literally. I have a condition that causes me fatigue, so I just figured I was having a relapse. My thyroid stimulating hormone (TSH) level had jumped to 13+. I didn't have the other normal symptoms like my skin/hair being dry and constipation, so I didn't pick up on it, it might be my thyroid or the medicine. Just in a fog, with extreme fatigue, pain, and irregular heartbeat. My doctor increased my meds. I talked to the pharmacist. I was told again that it was the same thing, but 'some' people have problems taking it. I asked if they could note it on the computer. I would have to call every month. Fast forward to almost a year later and I'm still trying to get things regulated."

For Hashimoto's disease "Nope. Euthyrox is not viable for Hashimoto's. I’ve asked for the pharmacist to continue dispensing the green generic tablets because of severe fatigue, headaches, weight gain, yada, yada, yada this medicine delivers. It looks like it may work for a couple of folks here but not the majority. Even if the pharmacist or doctor looks at you like you have no clue, every one of us realizes that fine line with levothyroxine. Even in ultra-low dosages, sensitive Hashimoto's patients know right away. I don't feel like garbage, so I pass."

For Underactive Thyroid "Was on generic levothyroxine for several years, then last year got switched to Euthyrox. Almost immediately started feeling awful. Nausea, shortness of breath, fatigue, headache, brain fog. My doctor couldn't explain why I was having issues. Reading similar reviews makes me realize it's not just me. I will have to find a better alternative because I can't function like this."

For Hashimoto's disease "Do not take it! I was switched from Levo when I moved states. I was miserable for the 2 months I was taking Euthyrox. I had extreme exhaustion, I would take the meds in the AM and be back in bed for hours after. I would get exhausted doing laundry. More exhaustion than when I was pregnant. Extreme depression, and my hair was falling out. Also, the weight gain. I found this website, and it made me not feel crazy, but it was, in fact, the medication. My family doctor told me my numbers are in range, that it couldn’t possibly be the medication causing all this, and that I needed a “happy pill.” This is as I’m crying in his office, begging for something different. He then agreed to put me on Synthroid. It was more expensive, but it is what it is. He had told me my mono came back… Listen here, 2 days being on Synthroid and I got my life back! 2 weeks on, and I was running around Disney not needing a nap! Do not take this crap!"

For Hypothyroidism, After Thyroid Removal "Worst drug on the planet! I had always taken levothyroxine until May 2022. I went to get a refill when the pharmacist at Walmart said they had switched to Euthyrox. He told me it was the exact same thing, so I thought nothing of it. The side effects were absolutely horrid. Gaining 15 pounds, having extreme fatigue, a rash on my chest, extreme irritability, and hot flashes, just to name a few. I feel like I was robbed months of my life taking this medicine that I was not warned about. Not to mention, in the meantime, we had spent hundreds of dollars seeing doctors thinking it was my hormones or maybe diabetes. Thankfully, I complained to my sister enough about how bad I was feeling, she googled the drug (something I never thought about because I was told it was the exact same thing as levothyroxine). I got off of it in September, and I still do not feel like myself! I hope and pray they take this off the market."

For Hypothyroidism, After Thyroid Removal "Weight gain of 2 to 3 pounds a month after levothyroxine was changed to euthyroid with a 40-pound weight gain. Have lack of energy and after 2 years have fatigue, thinned skin, chronic muscle soreness, and decreased libido."

For Underactive Thyroid "Walmart switched me from Levo to Euthyrox. I trusted that the medications were the same..... THEY ARE NOT!! I've been suffering for almost a year on this Euthyrox garbage. I've been sick, hair falling out, joint pains, migraines, diarrhea, fatigue, depression, heart palpitations, etc. TSH skyrocketed. I just got my new script and noticed it was Levo again..... after 5 days on it, I feel like a new person! Euthyrox is garbage! And I didn't connect the dots at all. I will NEVER take this AGAIN! I've been suffering for a year! Take this OFF THE MARKET!!!"

For Underactive Thyroid "I have been on thyroid medications (Synthroid and levothyroxine) for quite a few years with no problems and good results/bloodwork. Several months ago, Walmart Pharmacy placed me on Euthyrox, and it has been a downward spiral since that time. I began experiencing many symptoms that only continued to worsen over time: muscle aches, fatigue, brain fog, headaches, dizziness, dry mouth, weakness. It was relatively easy to tell myself I was depressed, I was working too hard, it was age-related (I am 74), and on and on. Finally, I went back to when my symptoms began and knew the only change in that period of time was my medication. Then I checked out patient reviews of Euthyrox and knew I was not alone, so why is this medication still being prescribed? I called my pharmacy to put me back on my levothyroxine and never substitute that medication with any other drug again. My following lab level also showed a decrease in my level. Why is it still out there?"

For Underactive Thyroid "I am certain that this medicine is harmful. I started taking it ten days ago. My doctor prescribed a lower dose of 112 mg instead of the 125 mg I have been taking. This is the tenth day of taking it, and I feel bad. I have been fatigued, sleeping ten hours, dull headaches, stomach pain. For the past four days, it feels as if I am sleepwalking through the day. I just called Walmart and asked them to replace it with Levothyroxine. They should stop selling this Euthyrox!!"

For Underactive Thyroid "After taking levothyroxine from Alvogen for 15 years and Synthroid prior to that, all with perfectly normal thyroid levels, Walmart switched my prescription to Euthyrox in late June. After a short time, I began to feel as I did when first diagnosed with hypothyroidism many years prior: rapid/irregular heartbeat, hair loss, insomnia, extreme fatigue, and new side effects such as difficulty swallowing, under-eye swelling, tightness in the chest, and nervousness/irritability. I called my doctor when Walmart again tried to give me a refill of Euthyrox. The doctor called in my original meds, and the cost went from $9 for 90 days of the levothyroxine to $288 now!!! I'm changing to a new pharmacy. I'm going back to 75 mcg of the Alvogen levothyroxine!"

For Underactive Thyroid "I have been hypothyroid for ten years. My medication currently is 125 mg Levothyroxine and 25 mcg Cytomel. I moved recently to Barbados and was prescribed the Eutirox. I had a personality change on them, I became sensitive to sound and highly irritated, aggressive, and my appetite increased and energy levels decreased. I know my symptoms very well and monitor any changes. My abdomen became swollen with fluid and painful, my face and eyes puffy. I was relieved to find this site."

For Underactive Thyroid "I too got this from Walmart. Just awful. Took it for two weeks and began feeling so dizzy I would have to sit down. Tightness in my chest, then had terrible heart palpitations. The fatigue and dizziness got so bad all I could do was sit on the couch. This is a clear case of the cure being way worse than the disease. Take this stuff off the market."

For Underactive Thyroid "This drug needs to be taken off the market! Should have been taken off before now with all the negative reactions. My dosage is 88 mcg. My experience after beginning this drug is as follows: insomnia, headaches, fatigue, blurred vision, heart palpitations, shortness of breath, leg cramps, weakness in legs. I am so angry! Can't we trust our FDA to approve only what is safe for us? Look at the low rating!"

For Underactive Thyroid "I had a bad experience with Euthyrox. I had extreme anxiety, weight loss, and fatigue. I have changed to a different generic of levothyroxine, and I feel much better. I would rate Euthyrox a 0 if I could."

For Underactive Thyroid "I have Graves' disease with RAI to get rid of my thyroid and have been taking Levothyroxine for 8 years. This past summer, I developed a stinging, itchy, red rash on my face that no doctor has been able to explain, and it continues to get worse. Then my heart palpitations came back even though I'm on a beta blocker for them as I have had MVP for the last 18 years. Also having extreme fatigue and feeling cold all the time with low-grade fevers. Just had my TSH, and it's .36 when it's always around 2.5. Can't remember it ever being in those low numbers. Never thought about the Euthyrox until today, so I decided to check when Walmart switched my Levothyroxine. Lo and behold, June of 2021. The rash started shortly afterward along with excessive histamine in my body, which my doctor has referred me to an allergist. Never had any histamine issues either until the same time when I was switched over to Euthyrox. I will be calling to get switched back to see if there's a change."

For Underactive Thyroid "I’m so thankful for this comment section. Walmart Pharmacy switched my Levothyroxine for Euthyrox. After a month and a half of taking it, I noticed I was feeling very poorly. Severe headache, thirst, muscle aches, extreme feeling of being cold, and generally achy and fatigued. After thinking about what I was doing differently, I did some research and realized it was likely the med change! Switching back to the Levothyroxine that I have taken for the last 20 years and hoping to be back to “normal” ASAP. Thanks, everyone, for sharing your stories. :)"

For Underactive Thyroid "Walmart changed my levothyroxine to Euthyrox. I questioned the pharmacist because I had never taken one in a blister pack. She said it was the exact same thing, that they had taken the dye out of the pills and repackaged. I started taking them, I got severely ill: lightheaded, fatigue, headache, heart palpitations, cold sweats, chest pain, and dizziness. I went to the doctor, he said I tested positive for the flu, still did not think about it being meds, so I wound up at the ER with chest burning, dizzy, body shaking uncontrollably. They said all my tests looked okay. Then he asked if I had started any new meds. I told him I started Euthyrox about 16 days ago. He told me to go back to my old pharmacy, not Walmart, and get them to fill a new prescription with the levothyroxine that I was supposed to be taking! I have been back on my regular meds for 2 days, still have a ways to go to get back to normal. People, please do not take this drug. I can’t believe Walmart is still dispensing this drug."

For Underactive Thyroid "I have been taking 125 mcg levothyroxine for 30 years, and everything has been well. Walmart changed my prescription to Euthyrox, and I have had chest pains, racing heart, followed by a slow heartbeat, headaches, and a general malaise. Do not take this medicine! Something is not right with it."
