For Underactive Thyroid "DO NOT TAKE THIS. I was on Nature-Throid with no problems for about a year before being switched to this garbage due to recall. I took NP Thyroid for about a week and ended up in the back of an ambulance this morning because my husband thought I was having a heart attack. I am a 30-year-old female athlete with no underlying health conditions other than an underactive thyroid. The past week on it has been a blur. Brain fog, irritability, heart palpitations, achy body and joints, breathlessness, migraines, nausea, dizziness, extreme fatigue, and anxiety. I don't know what's in this stuff, but it needs to be pulled. There is something very wrong with NP Thyroid. Stay far away from this stuff."

For Underactive Thyroid "I’ve been on NP for 4 months. I haven’t been feeling well and have a splitting headache, so I googled side effects. I don’t know what made me think it could be thyroid medicine. For some reason, it just popped into my head. I have very bad headaches daily, bloated stomach, constipation, I’m very cold all the time, foggy, and just out of it. I’m so tired and have a 'I don’t care' attitude. I used to take levo and didn’t have any of these problems. My numbers aren’t changing, so the doctor keeps increasing the dosage. Now at 120 mg, I have such blurry vision, which is sometimes double vision. Heart palpitations. Chest pain. Joint pain. I can’t sleep. I'm glad I came here to read, I thought I must have a terrible disease. Seeing doctor in a few days."

For Underactive Thyroid "I was on Nature-Throid for quite a long time and was doing great until it wasn't available. Then, I switched to NP Thyroid for the past year or so. The NP Thyroid has given me horrible insomnia, heart palpitations, terrible anxiety, and many more symptoms. I was so grateful to find this site and read everyone's reviews because I didn't really put it together until I started digging. I don't know what I'm going to do now for meds, but I am not staying on this any longer. The last few batches have been really bad, and I've been feeling much worse. Thank you all for writing!"

For Underactive Thyroid "Was on Armour for 10 yrs with good results, good consistent labs. Last year, the pharmacy refilled with NP Thyroid on and off, claiming availability issues, then insurance denial. So, in November 2019, decided to just keep the script NP. Labs last year not as good. In January 2020, had a horrible episode of nausea, dizziness, increased BP, irregular pulse, and flu-like symptoms. Took a few days to realize intensity increased a couple hours after dose. Stopped for a few days, then took a partial dose for a month, noted puffy face, so went back to full dose. This past week, symptoms recurred along with a very bloated, gassy stomach, constant belching, scary high BP, palpitations, and dizziness. Ended up in the doctor's office. EKG showed PACs. My weight also went up 10 lbs past year. Just picked up Armour, paid out of pocket, hoping all these symptoms disappear. See many here had similar experiences."

For Underactive Thyroid "Last week, my pharmacy gave me NP Thyroid instead of regularly prescribed Armour Thyroid. At first, I noticed the strong smell and taste of mildew/cat wee. I checked the label on my prescription and noticed it wasn’t Armour. A week into taking this, I noticed my body aching and heart palpitations. Then my heart started pounding, and I got all jittery. My hands and knees were shaking, and I felt weak with a headache and brain fog. I called my pharmacist, and after talking to them, they exchanged that medication for my regular Armour. After looking into this medication, I found out it has been recalled multiple times, and my symptoms were identical to other multiple people's reviews. Please do not take this medicine. It is terrible."

For Underactive Thyroid "I was put on this after Nature Throid was recalled. I ended up with atrial fibrillation. I stopped the drug. A cardiologist told me to restart it. I then had hyperthyroid symptoms after four days when I am actually hypothyroid. This drug needs to be recalled. Nature Throid never caused me any problems. It just did its job."

For Hashimoto's disease "I’ve been on Armour thyroid for over 10 years, taking 60 mg daily. My prescription got filled with NP thyroid this last time. When I received it, I saw the change, quickly looked it up, saw desiccated thyroid and figured it was fine. I finished my Armour and switched over. I was also recently diagnosed with type 2 narcolepsy for which I’ve been taking Modafinil for the last 4 months. So when I started developing headaches, palpitations, hypertension, and GI bloating, and let’s just say it-farts-I actually thought it was that. Even though it’s only been about a month of those symptoms. Today as I sat here and pondered why the headaches and increase in BP, I thought of the thyroid medication switch and started poking around. And here I found some answers. Along with reading the differences in Armour and NP. I won’t take it tomorrow or the next day, until they give me Armour back. Be alert to what feels good, right, and normal. Be persistent in your health!"

For Thyroid Cancer "When I found NP Thyroid 11 months ago, I got my life back. I struggled for a year on different medications after a total thyroidectomy for cancer, but now Acella changed all that. That's over now. They changed the supplier for the active ingredient, claiming it worked exactly the same. It does not. I am having memory problems, brain fog, heart palpitations, headache, and a burning throat. There is something wrong with these pills. No more NP Thyroid for me."

For Underactive Thyroid "I took NatureThroid for 12 years without problems and good results. It was recalled. I found I could not take Synthroid, which tore up my digestive tract. I tried Tirosint and no go. Endocrinologist switched me to NP Thyroid. I went to the ER with a head injury, and that had no ill effects. I was not allowed to leave and was detained for 10 hours because I had atrial fibrillation. I came home with a beta blocker and a blood thinner, which I hope are temporary. This is a dangerous and horrible drug. Irregular heartbeat is a listed side effect. I reported it to the FDA, mentioning that the recall of NatureThroid caused this situation."

For Underactive Thyroid "Started taking NP Thyroid about 3 weeks ago. I was taking WP Thyroid due to recall, no longer available. I have chronic Lyme and co-infections. I've been feeling a lot better lately. About 2 weeks ago, I started feeling very anxious, heart palpitations, extreme fatigue, severely depressed, brain fog, muscle pain/aches, and the list is endless. I really thought it was one of my co-infections coming back. Paid $580 to get tested for it, and I was negative. Couldn't figure out what was causing all of this until I Googled NP Thyroid, it smells like cat pee. I will no longer be taking it. I don't know what to change it to, I see my doc on Monday, I hope to get it sorted. Please don't touch this stuff."

For Hypothyroidism, After Thyroid Removal "I was on Synthroid for 14 years after my thyroidectomy (thyroid cancer). My body stopped absorbing Synthroid medicine. My doctor prescribed NP Thyroid, and I figured, great, something new and I’ll finally feel better. The exact opposite happened. I had diarrhea for 2 months every single day (I’ve never had stomach issues), heart palpitations, and I was tired all the time. Talked with my doctor this week, and we checked my levels. My T3 and T4 were dangerously low. For 2 months, the medication didn’t work at all. I called the pharmaceutical company today to put in a complaint and am waiting for someone to call me on a recorded line. It’s alarming to read all of these comments and hear that we all have similar issues. I’m a working mother who needs to have my medicine to function. I’ve missed work, sporting events, and time with my family. Please look into these ingredients, fix them, or remove this medication from the market."

For Hashimoto's disease "Finally, a medication that works wonderfully! I have never felt better. So far, so good! Used to be on Naturethroid. Had heart palpitations, highs and lows. The Stop The Thyroid Madness Support Group I follow has its members highly recommending NP by Acella. However, I do not understand the shortages in these thyroid medications when they are so desperately needed! The AMA has a lot of catching up to do because their protocol is counterintuitive and productive for patients like me who have been un and underdiagnosed for years! Time to wake up!"

For Hypothyroidism, After Thyroid Removal "Will never take this rubbish again!!!! I have no thyroid and thought this would be a good med since it's natural, wrong!!!! Dizziness, heart palpitations, extreme exhaustion. I am going back to levo as my labs were horrible on NP - elevated T3, but the rest low. No more of this horrid drug."

For Hypothyroidism, After Thyroid Removal "I kept feeling bloated at the top part of my tummy. I had heart palpitations, then realized that they changed my medication from Armour Thyroid to NP Thyroid. I actually just stopped taking it. I know I probably shouldn't, but with COVID-19 and no doctor's appointment in sight, I just wanted to feel better, and I do! I thought I'd start taking Armour again and called the doctor's office, and much to my surprise, they called it in. I checked online with the pharmacy, and it's NP Thyroid! OMG, are you kidding me? I have to call the pharmacy tomorrow and see about changing to Armour again. Geesh! I used to take NP fine until several months ago."

For Underactive Thyroid "A year ago, this month, I was suddenly finding it difficult to get NP Thyroid 30 mg. I started getting it easier through a different pharmacy. In October, I noticed a lot of little purple spots on the back of my hands. I’ve continued getting them here and there on my arms and hands. As well, I had strong heart palpitations that would sometimes make me feel faint. I had my heart checked out twice, but nothing explained the palpitations. Add to all that, I noticed my upper abdomen was feeling bloated. I was also feeling tired and anxious. Something wasn’t right. A few nights ago, something made me decide to research NP Thyroid medication, and I was shocked to see some of the side effects people were having. I quit taking it, and already, no more little purple spots! After a year of seeing them pop up here and there on my arms and hands - gone. I’m wondering if I have damaged my health taking it for a year. Don’t take this medicine!"

For Hashimoto's disease "I was on levothyroxine for over 2 years and had constant palpitations, anxiety, and heat intolerance. Thyroid levels were WNL [within normal limits], saw a new endo who let me discontinue because my initial TSH was under 10. After 3 months of no meds, I had zero energy and all of my muscles and joints hurt. Started NP Thyroid, and I feel so much better, but I am gaining weight, about 6 lbs so far and don't seem to be plateauing."

For Underactive Thyroid "I had been on Levothyroxine for 10 years, but in the last 4 years, I had been struggling. There was even one occasion where I was hospitalized for heart palpitations, and come to find out my thyroid was all messed up. I had been on 150 mcg for two years but started to notice my skin, hair, nails, and of course weight was off (weird weight gain, no diet changes). I moved and started a new doctor who recommended NP Thyroid. She started me on 90 mg. The first two weeks, I noticed a rapid heartbeat, but nothing scary. By week three, I felt like a superwoman and had my normal energy back! After four weeks, I finally feel better!"

For Underactive Thyroid "I started BHRT and Thyroid NP (60 mg) at the same time. Nine days after starting, had to call an ambulance because I thought I was having a heart attack or stroking out... horrible chest pressure, uncontrollable shaking, heart palpitations, dizziness, pain shooting up into my neck and jaw, left arm numbness. I told my doc that I think I had a reaction to this medication, but she didn’t think it likely. She told me to reduce the dosage of this and then increase it every couple of weeks. Started back at 15 mg, then 30 mg, and now 45 mg. Have been feeling like rubbish... mood swings, irritability, fatigue, and more recently really bad anxiety. Thought it was my hormones trying to balance out. Was getting frustrated because I thought the BHRT was supposed to make me feel better, but I just felt like rubbish all the time. Now I realize it may have been this medication this whole time causing me problems!!! Going to stop taking it. Very healthy and athletic prior to taking this. Now I feel like a mess."

For Hypothyroidism, After Thyroid Removal "I began NP a couple of weeks ago. The third day, I developed bad headaches and was dizzy. This past weekend, my BP soared and I began having heart palpitations. I stopped it today, and this evening I am beginning to improve. I will never take NP again."

For Underactive Thyroid "Took Synthroid from age 29-50. Felt okay but had osteoporosis on a bone scan. I was told Synthroid caused the osteoporosis. Started on Armour thyroid and felt fine with normal labs. My osteoporosis reversed to osteopenia. Went to a new doctor in 2021 (age 69) who refused to prescribe natural thyroid. Started back on Levothyroxine. I now feel terrible. Not sleeping, short of breath, weight gain, jittery, palpitations. My dose was lowered from 137 to 75 mcg. Still don't feel good. Finding a doctor to start natural thyroid again. My particular bottles of natural thyroid were never on the recall list. Synthetic thyroid is cost-free for me. Natural stuff not covered. I have one half of my thyroid due to partial removal at age 28. Rating below is for WP or NP thyroid."
