For Underactive Thyroid "Update: I posted on March 11, 2021, and shared how I switched back to my regular medication from Walgreens, which is just the generic Levothyroxine 88mg and stopped taking this horrible pill from Walmart called Euthyrox, which is their version of the generic brand but with horrible side effects. Today is April 21, 2021, and I feel like a brand new person! I finally feel normal! I prayed for this moment to feel like my old self! The horrible side effects have all subsided!! I just want to share with everyone that there is hope! I’ve been trying my hardest to be patient with my body. I also was taking ibuprofen for the aches and pains in the meantime. But I can finally share with you all that I’m doing great! I pray for everyone else to feel better soon. There is HOPE and light at the end of the tunnel."

For Underactive Thyroid "I was taking Levothyroxine 88mg from Walgreens or CVS since I was 18. Now I’m 33. Switched pharmacies to a neighborhood Walmart because it was closer to home back in Sept 2020. They gave me a generic called Euthyrox and said it was the exact same thing, so I trusted them. They just said the packaging was different. They were so wrong! Since September 2020, I’ve been having horrible side effects - muscle aches, pains, and stiffness all the time! Muscle weakness, blurred vision, chest pains, severe acid reflux (GERD-like symptoms). Foggy brain, forgetfulness, and feeling cold all the time. Didn't feel like myself at all! I almost passed out twice last week and had enough! I went to the Dr and she immediately switched me back to my meds from before. Today will be 6 days that I have switched back and my side effects have been subsiding. It was so scary and still is knowing this medication is out there! Please don’t take it. When I almost fainted and had chest pains, that was the scariest part for me."

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 Hashimoto's disease "I was on Levothyroxine for three years. Three months ago, Walmart (without permission) changed my prescription to Euthyrox. At the time, I didn't think it would matter, so I took it as I had my previous med. I started having leg and hip pain - then extreme brain fog - tingling and numb extremities - depression. I went to the doctor and was told my levels were within range. The doctor stated he had not heard of Euthyrox. Nothing has changed in my life (other than COVID), but the med. I called Walmart, and they told me they could no longer get Levothyroxine. The pharmacist explained that Euthyrox was much better in foil packs and would not lose its purpose as Levothyroxine would once it was open. After reading other comments, I'm switching back and to another pharmacy."

For Underactive Thyroid "I was switched from my levothyroxine a few months ago. There was a doctor's name associated with it that I have never seen or heard of. I was given Euthyrox, and I also fill my prescription at Walmart. For a while, I have felt awful. More headaches, tired, achy, mood drops, thirsty, and have to pee more. Probably because I drink so much water at work. I am always hot, especially at work. I have been thinking it was because of the mask I have to wear at work. We are not allowed to use indoor fans either, so I get overheated, sweaty, thirsty, and headaches. It's been a vicious circle of not feeling well."

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 Underactive Thyroid "I have taken now for about one year. I can barely walk due to severe edema in bilateral knees causing terrible pain. I have even had injections without resolution. My legs have become extremely weak, and I chalked these changes up to growing older. I am calling my Dr. and pharmacy today. Also, I'm having numbness and tingling in bilateral hands/lower arms."

For Underactive Thyroid "Walmart switched me from levothyroxine to Euthyrox a year ago. I started feeling weak and had lightheadedness. Leg and back pain. I went through heart tests and physical therapy for back pain. A week ago, I went back to levothyroxine and now feel 80% better. Walmart should have a lawsuit to cover all our pain and suffering over their horrible generic Euthyrox medicine."

For Underactive Thyroid "I’m so glad to know I’m not the only one! I’ve been on Unithroid for 2 years for hypothyroidism with no issues! Went to Walmart Pharmacy and was given Euthyrox. I have been taking it for 4 days, and I’m nauseous, no appetite, my body hurts, headache, and insomnia! What the heck! I called my doctor this morning, and he contacted the pharmacy to tell them to refill my Unithroid! I haven’t felt this sick in years."

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 have been on Levothyroxine for 25 years with no issues or side effects. Was given Euthyrox at Walmart back in July 2021 instead of my usual Levothyroxine. When I questioned it, I was told that they were exactly the same. After about 4 weeks on this medication, I started to experience weakness and trembling in my arms, legs, and shoulders, pain in my knees, legs, hips, and shoulders, rapid heartbeat, nervousness, anxiety, restlessness, bloating, fuzzy feeling in my head, and my feet and hands being cold all the time. I found all of these reviews and stopped taking the Euthyrox the next day. I have been back on Levothyroxine for 2 weeks now, and the side effects have subsided, but my arms and legs still feel strange, and I still have pain. This medicine has made the last 2 months of my life a living nightmare."

For Hypothyroidism, After Thyroid Removal "I had the right side of my thyroid removed 3/10/20 and started on Euthyrox about one month later at 75 mcg from Walmart, and the side effects stink. Since I have not been on this medicine, side effects are terrible. They have switched me to 50 mcg and have more side effects. Going to switch to Walgreens to see if anything is better. Because I can't live with the pain I am in right now."

For Underactive Thyroid "Wal-Mart switched my medicine to Euthyrox and told me the manufacturer changed because my current levothyroxine absorbs moisture. Within a week of taking Euthyrox, I had a rash on my legs. Two weeks in, a horrible rash appeared on my hands and feet. My body itched on my trunk, front and back, continuously. By the third week, most of my hair had fallen out, and I experienced tiredness and pain in my hips. After taking Euthyrox for 27 days, I had Wal-Mart switch me back to my old medication. It's been 6 weeks since I switched. The tiredness and hip pain are gone. The rash on my leg is mostly gone. The horrible hand and feet condition remains. My primary doctor gave me cream for eczema. The dermatologist has given me two different creams for eczema or psoriasis. My hands were dry, scaly, very red, and flaky. My hands itch and hurt at the same time. They appeared like burnt hands. My feet have very hard and dry patches. I am praying for some answers. How long will this problem last before it clears up? Has anyone else had this rash?"

For Underactive Thyroid "Please do not take this medication. My pharmacy switched me from Levothyroxine to Euthyrox, and since then I've been having anxiety, fatigue, loose bowels, extreme sweating, muscle aches, and pains. Called the pharmacy today, had them switch me back to Levothyroxine. Hopefully, this will help."

For Hashimoto's disease "Two years ago, my pharmacy switched over to this and told me it was Levothyroxine, just under a different brand name. Me or my doctor did not put the two together. I gained 30 lbs, and I now have chronic fatigue and pain, slow heart rate. I stopped running because the fatigue was so horrible I could barely function going to work on a daily basis. My quality of life was failing, and I felt like no one was listening to me. When I switched pharmacies, I was getting Levothyroxine again, and in two weeks, I noticed more energy. By week three, I was running again and actually able to clean my house, run three miles, and make dinner and have guests over, all in the same day! This drug was ruining my life. I can't get back the last two years, but this drug needs to be removed from the market. The sad part, my TSH was normal, so my complaints were ignored."
