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 have used this without a problem until I refilled my prescription in October. I have become increasingly sick since taking this bottle. It started with a flu/cold that wouldn't go away, then horrible stomach pains, and then the fatigue set in, where I literally could not get out of bed. In addition, I had abnormally high blood pressure. I went to a few doctors who had no answers until one day I noticed when taking my NP that it tasted different. I might have noticed it before but disregarded it. I did some research online and found that the specific batch I am taking which is M330E19-1 is on the STTM website list of problematic batches. I discontinued it today and will switch to Armour. It's becoming harder to get reliable desiccated thyroid."

For Underactive Thyroid "I was on NP Thyroid for 3 years and finally got my life back. There’s a change in my most recent refill that has made me sick to my stomach, headache for days along with unbelievable fatigue. The pills smell like cat urine and taste the same. How dare you endanger so many people that are trying to regain their health. Do NOT buy NP Thyroid!"

For Underactive Thyroid "I've been on Armour Thyroid for years and felt fairly good. My doctor switched me to NP Thyroid recently because Armour is no longer covered by insurance. NP Thyroid is awful. Not only did it cause some thyroid symptoms to return (trouble waking up in the mornings, extreme fatigue, depression, weight gain, and irritability to name a few), but it also caused new symptoms. My stomach hurt a lot with acid reflux symptoms, and I had constant mucus in my throat, which created a chronic cough, to the point where I had to clear my throat every 15 minutes. After being back on Armour for a couple of weeks now, all of the symptoms/side effects have disappeared, and I feel good again."

For Hypothyroidism, After Thyroid Removal "I have been on thyroid for 15 years. 8 years before thyroid removal, 7 years after. I started with Synthroid at the beginning, I felt 'normal.' Then it was difficult to get Synthroid, and I switched to Nature Thyroid. Was on that for a very long time, made me feel better, no headaches, didn’t fluctuate in weight. Then the money-hungry pharmaceutical companies decided that we didn’t pay enough for our working thyroid medicine and didn’t make enough. So, I switched to NP. Now I am back to being fatigued all the time, migraines again, weight gain, brain fog, cramps in my legs, the list goes on. When are these pharmaceuticals going to be accountable for screwing with the well-being of hundreds of thousands of people?"

For Hashimoto's disease "I started taking NP Thyroid in March 2019 after 20 years on Synthroid. Once my dosage was correct, I began to feel so great. I felt like I was actually a functioning human being again. And then I got the 'new' batch in October and immediately felt terrible. I had zero energy, could barely walk down the stairs, deep hip pain. I examined the pills, and they looked different (speckles) and smelled terrible (now smelled like cat pee, instead of just kind of unpleasant). Thankfully, I had some of my old batch left and resumed taking that and immediately talked to my doctor about switching to a synthetic T4/T3 combo so this wouldn't happen again. I've been on the new meds for 5 days and not feeling well yet. Not sure if it's from the doses of bad NP I took or just getting used to new meds. This is just heartbreaking. So many people having terrible reactions to the 'new' formula while Acella is saying basically that it's all in our heads. I just want to feel better."

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 Hashimoto's disease "I stopped taking NP Thyroid after my symptoms got the best of me. Aches, dry eyes, fatigue. When I called Acella, they said, 'batches can be different, but the standards are the same.' I told them to raise the bar. Their new 'batch' smells horrible, tastes even worse, has a different size and look, and makes me feel worse than ever. How can that be acceptable?"

For Underactive Thyroid "Was doing well on Naturethroid, up until they seemed to change the formula. So switched to NP. Fatigue okay, but brain fog much worse, painful joints, stiffness in muscles, and leg pain that feels similar to restless legs. The worst symptom though is headaches-constant. Am now experimenting with altering my dose (again!), but I’ll have to swap to Armour, I think. I’m in the U.K. Getting hold of NDT is like finding a unicorn. I despair. I wish Naturethroid had never changed. I know they deny a reformulation, but it worked like a dream for me before their manufacturing issues, and I felt well. Now I’m back in the hypo pit, and it’s dreadful."

For Underactive Thyroid "NP Thyroid failed me and made me lose my baby. Or perhaps it was the pharmacy that switched my medication without informing me. I was on Armour for about 5 years, doing fine. Then I suddenly had a regression of all my hypo symptoms in about 2 weeks. The third week, I skipped a day, then took the pill. Within a few hours, I was fatigued, had headaches, joint pain, incredible water retention, and chest tightening... After doing this a second time, I knew for sure it was the medication. I then noticed that my med bottle said “NP Thyroid.” I called the pharmacy, and they said they had replaced Armour with NP 6 weeks before. They did not inform me! NP totally didn’t work at all for at least a month. And while I took this failure of a medication, my pregnancy failed because I had no functional thyroid hormone to sustain it. I found that NP costs cents while Armour does not. It’s a case of insurance companies trying to pay out less $$, even at the expense of real people’s health."

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 Underactive Thyroid "Have taken Armour thyroid for 45 years. Pharmacy switched me to Acella thyroid NP. After a couple of weeks, I realized something was wrong. Low energy and just slowed down. Pharmacist insisted that was Armour thyroid! My experience is that Acella thyroid is garbage and smells awful too."

For Underactive Thyroid "I have been on Nature Throid for years and have felt great. My doctor switched me to NP after Nature Throid was recalled. I felt okay at first, and now symptoms are popping up: sore arms, depression, constipation, brain fog, weight gain, puffy skin, and fatigue. This medicine isn't consistent, and not to mention, it smells and tastes like pee. Stop recalling medicine that works for people for pharmaceutical benefit. It's wrong. This stuff is junk."

For Hashimoto's disease "Was switched to NP Thyroid after Nature-Throid was recalled. I was doing really well on the Nature-Throid, but I tried to stay positive in taking this one. It smells and tastes disgusting. I noticed unexplained pain in my hip, constant indigestion, upset stomach, random diarrhea. Seven months in and my T3 is off the chart, T4 and TSH are super low, basically hyperthyroid. In the past month, I developed horrible anxiety, crying randomly and uncontrollably, trouble sleeping, and fatigue. I barely recognize myself. Had a complete breakdown in the middle of an exam. My professors are mad and think I'm somehow incompetent, although I kept trying to explain I didn't know what was going on. Finally went to the doctor and found out she had prescribed Armour, but my pharmacy was filling NP instead. I'm fighting with insurance to get Armour covered, but I can't continue with NP. My temporary dose of Armour already smells better than the NP. I'm praying this works, because I don't know what I'm gonna do if it doesn't."

For Hypothyroidism, After Thyroid Removal "I never write reviews, but want to share my experience with NP Thyroid by Acella. I have many of the same problems listed here already. I have taken thyroid replacement for 20 years. I had been on Armour for years; my dosage is closely monitored as my blood levels fluctuate a lot. My doctor switched my dosage, and the pharmacy filled it with the generic NP Thyroid instead of Armour. We have new health insurance. I decided to try it; maybe it would help keep my levels more steady. Three weeks in, and this is the worst I have ever felt mentally. I have never been so depressed in my life. I have dealt with anxiety, but this is different: hopeless, weepy, with a dark depression. I have gained over 10 pounds, and all I want to do is sleep. The confusion and brain fog are almost scary; I can't remember or figure out simple things I do every day. Maybe if I could give it more time, my body would 'adjust,' but I had to call my doctor to go back to Armour. There is no way I could take the NP another day."

For Underactive Thyroid "Had been taking 120 mg of Armour Thyroid for years when the price shot up. I looked for an alternative and was on Nature-Thyroid and had no problems when suddenly it disappeared from the market. I went back to Armour but was sick of the price gouging and found NP Thyroid. I have been on it for a month now and have been an utter mess. The first week was fine, but then a sudden drop in general well-being. I cannot focus, constant fatigue, grogginess, barely able to function, balance is off... just generally horrible. Thankfully, I am able to get Nature-Thyroid again and am waiting for the new prescription to arrive. Once it does, NP is going in the trash. Avoid... avoid... avoid!!!"

For Hypothyroidism, After Thyroid Removal "Walmart pharmacy substituted NP for Armour thyroid. It makes me very depressed, sleepless, and fatigued. It makes me angry because they did this without my permission after I told them before that I didn’t want NP because of the same issues before. I would avoid NP!!!!"

For Hashimoto's disease "Loved NP Thyroid but then started feeling really ill. Migraines, fatigue, nausea, joint pain, brain fog, etc. This was my lifesaver and now just horrible. My doctor switched me to medication from a compounding pharmacy. So disappointed in Acella Pharmaceuticals for changing what was a wonderful product."

For Hashimoto's disease "Switched from other brand after moving to a naturopath Dr. to help with my Hashimoto's. I really would not recommend Thyroid NP. For the last 2 years, I’ve had stomach burning, enough to make me think it was an ulcer, and loss of eyebrows and hair on my head, absolutely zero energy, leg aches, weight gain, and a massively foggy brain as of lately… I’ve been off for 3 days, and I can already feel the difference. Leaving my naturopath and heading back to my regular Dr. for Synthroid. I didn’t connect the dots until recently. And this stuff is not regulated well, it had 3 recalls in the last year… that’s not good."

For Underactive Thyroid "The quality of NP is poor. Hypothyroidism - thyroid not working at all. Switched to NP because Armour’s price shot up with my provider. It took a month to realize that it was causing my eyebrows to thin, my skin to be bad again, and my moods to be all over the place. I’m very weepy. I don’t have a lot of energy. It is supposed to be the same formulation, but if it is, why would I experience this? I have a lot of NP and have been adding an extra pill each day. It helps a little, but I don’t even think that’s enough. I’m unable to concentrate and I just want to sleep! I’m switching back as soon as I run out, and my insurance provider will cover the next prescription. They won’t cover the switch right now because I have a 3-month supply of NP."

For Underactive Thyroid "It smelled and tasted like cat urine. I began having headaches, fatigue, and joint pain within a three-week period. I called Acella Pharmaceuticals and complained and requested a refund. They have a do-not-refund policy, which essentially means that they don't guarantee their product. My doctor wrote me a prescription for Armour, and my symptoms subsided within a month. Life lesson for me. Never again will I purchase NP Thyroid medication."

For Underactive Thyroid "5 months ago, I refilled my thyroid meds, which at the time I thought were Armour Thyroid, which I have been taking for years. Probably a week after, I wasn’t feeling well at all. I hurt all over. My legs got heavy and hurt anytime I was active. I kept getting the chills, headaches, and very fatigued. My joints and shoulders hurt. I had blood work done to see if it was my kidneys. I felt like I had a pelvic infection, and some days I felt like I had the flu. I looked online to see if there was a recall on Armour, and NP Thyroid came up, that some lots were recalled because of super potency. I then looked at my bottle, and it said NP Thyroid. My doctor never prescribed that. Today is the first day I haven’t taken it, and I already feel a little better. I’m so upset to see all the complaints. Please make sure you know what you are taking, and they have Armour in stock. If my doctor changed it, I probably wouldn’t have gone through all this for five months. He would have told me."

For Underactive Thyroid "I started taking NP Thyroid in June. For the first week, I felt great, but then I started to notice some of the pills had a terrible odor, and the taste was worse. I have cats, and they smelled like cat urine, as well as my urine. Not every pill had the odor, but the ones that did, that I took, caused me terrible stomach cramps. Then, as time went on, my hair loss was terrible, constipation was 5 days, anxiety, depression, severe fatigue, it all came back as well as hot flashes. I let my doctor know, and he wanted me to have blood work before he made any changes, so after 5 weeks, I had blood work. I got it back, and my T3 was high, TSH low, and T4 was good. Before the blood work, I had blood work done, and the levels I just mentioned were all in range. I stopped it immediately. Unfortunately, my doctor is on vacation, so I can't get any meds like LDN, which worked wonders for me in the past. I am so exhausted I can barely function. I would not recommend this medication to anyone."

For Underactive Thyroid "I have taken Armour Thyroid for years. I picked up my refill prescription from Kroger pharmacy and didn’t notice that I received NP Thyroid. Called the pharmacy and was told that the computer said generic and not Armour. It smells awful. Since I paid $70.00 for a 90-day supply, I thought I would just start out taking one every other day and still take Armour so my body could adjust. On the days I am taking NP, I am feeling okay until about 10:00 AM, then have a headache and am so fatigued I can’t get anything done. My body is aching too. I’m going to the pharmacy and getting my money returned."

For Underactive Thyroid "NP caused my heart to race and anxiety to happen. Never in my life did I have anxiety, so that was a real surprise. Fatigue never went away. Now that it has been recalled, I don't know what Dr. will put me on."
