Tecfidera (dimethyl fumarate): “I've been on this for a 1.5 years. I had no issues from the beginning. No new lesions since diagnosed. No stomach issues. My arms will itch every now and then. There are people that are like me and don't have any problems. If you are trying to decide on this drug- know that.”

Tecfidera (dimethyl fumarate): “I’ve been on Tecfidera since October 2016. MS diagnosed 2006. Been on Copaxone, Rebif, Gilenya, Tysabri. I’m now Secondary Progressive MS (not even 50yo yet). For first year on Tecfidera my side effects that I had were severe flushing, rash, and itching which lasted about 2 hours after each dose. I was told by neurologist to chew half to full baby aspirin with each dose to help with the Tecfidera side effects and it worked - NO MORE FLUSHING or ITCHING. For the past two years I’ve been able to reduce the amount of aspirin to about a 1/4 baby aspirin per dose. Sometimes I can go without it for a day or two. But the chewable baby aspirin (84mg) works like magic to take away the severe flushing, rash, and itching. Also, I’ve only had one exacerbation since being on Tecfidera and it was mild. Such a huge relief because I had exacerbations every 12-18 months previously. I’m not switching off this as long it keeps working. Especially during this pandemic! No way I’m going in for infusions.”

Tecfidera (dimethyl fumarate): “I have been on Tecfidera for 8 mths for MS and have decided to stop. Since taking it fatigue has gone through the roof to the point I can't work anymore. Also I had hair loss which is not a noted side effect. I felt better when I was taking nothing (previously on avonex). We all react differently but I just feel a break from any drug worth a shot to see if life improves. Good luck everyone x”

DEE · November 3, 2019

Tecfidera (dimethyl fumarate): “I was diagnosed in March of 2019 with MS and put on Tecfidera in August. The pain from the burning for hours is terrible. It's NOT a flushing feeling. It's burning. My scalp, chest , armband, back area. Told my Neurologist and he said stay on it a while longer to get adjusted to it. But the burning feeling won't let you. Something is wrong with those ingredients. No medication should add to your problems that bad. Praying for another medication for all MS patients to get some relief.”

Tecfidera (dimethyl fumarate): “Its really sad that a medication that is needed for somebody suffering with MS costs so much. My mom can't afford it and there are no grant's available. Sad that she will now suffer because pharmaceutical companies are greedy.”

CLS · Taken for 2 to 5 years · September 26, 2019

Tecfidera (dimethyl fumarate): “I was put on Tecfidera 5 years ago to change from 5 years of daily Copaxone injections. Initially, I was fine with it. At year 4 side effects attributed to the medication began. Sinusitis and headaches started. Medications to treat these issues did not work. Then came the skewed liver function tests. Since long term and untreatable liver damage would occur, I was taken off of it. Now that I have been off Tecfidera for 4 months I am healthy again. I was diagnosed 10 years ago and my repeated MRI and testing show no new lesions or inflammation has ever occurred during this time. Sometimes I wonder if I really do have MS.”

Tecfidera (dimethyl fumarate): “Dont take it! Side effects are miserable. Felt like I was better off dead. Over a year I hung in there because my Neuro said give your system time to adjust. Don't listen to them. Gastric issues, flushing for hours. My body is on fire and I'm sick as a dog like you have the flu. Made my body hurt. Take something else. Trust me.”

Tecfidera (dimethyl fumarate): “It is my 1 st medication since diagnosed in 3/13. Just had my 14 month check up MRI, No new lesions. It is hard to adjust to for some people, but if you stick it out by month 3 it starts to get better.”

Tecfidera (dimethyl fumarate): “PML (Progressive multifocal leukoencephalopathy) side affect? My mother almost died from PML. After contracting the virus, she then contracted IRIS. She was on a feeding tube and had a week to live. It's a miracle she is still with us. She's still alive, but this 56 year old woman has spent the last three years relearning how to do basic life skills. She can barely walk or talk. She needs constant one on one care. There needs to be a better option for people with MS.”

Tecfidera (dimethyl fumarate): “I was taking Tecfidera for about 2 years. I regularly had my white blood cells checked. They dropped below 1 and dr took me off and no medication until white count comes up. After two years my white count has not improved. Still no MS medication, luckily no new flare-ups of my MS. If you take this medication, please keep a check on white blood cells.”

Mason · Taken for 2 to 5 years · February 26, 2020

Tecfidera (dimethyl fumarate): “I have been on Tecfidera for 5 years. The only side effect I ever have is flushing. I always take the pill with a full meal. The flushing normally comes on if I eat lunch. Maybe eating once the pill is fully in your stomach reacts with the lunch, I'm not sure. Over all, even the flushing is normally minor and goes away after 10 mins. I have had no flare ups in the five years I've been on the med that I know of.”

Tecfidera (dimethyl fumarate): “Been on T. since May 2013. Was allergic to Copaxone so was on Rebif for years. Pill is so much better. Side effects of flushing, burning last only 10-15 minutes during the first month or two of starting the pill. Cold wash cloth and relaxing helps during the flushing. Working so well...no new lesions. I drink a lot of water and eat protein when I take the pill. Highly recommend trying!”

Nurse Lauren · Taken for 1 to 6 months · October 2, 2018

Tecfidera (dimethyl fumarate): “This is the 3rd drug I’ve tried for RRMS (Relapsing Remitting Multiple Sclerosis). About 5-6 weeks into taking it, I did start to notice the facial flushing. About 3 hours after taking a dose, my face would turn red, then start burning and itching for about 20min. Also had stomach cramping and nausea. Taking Aspirin 324mg chewed and taking the 1st dose after 9am with a snack helped reduce those symptoms. After taking this drug for 3 months, I suddenly developed severe joint pain and swelling that limited my movement. The pains were there when I woke up and would resolve in one joint and present in another throughout the day. I’ll be leery of these drugs from now on. Background info-I take VitD 50,000iu weekly, B-12 500mcg daily, and Align daily. I am a runner and a nurse.”

Tecfidera (dimethyl fumarate): “Been taking tecfidera for my MS about 4 months been having hot flashes very little stomach discomfort but my huge complaint is my hair is falling out it’s pretty bad and very upsetting from a woman’s stand point. Trying to switch from Tecfidera which was my first MS drug - I was diagnosed in July. The hair loss is not a common side effect but I think it needs to be added to the list!”

Tecfidera (dimethyl fumarate): “I've been off and on this medicine since 4/2013 (not because of side effects, but because I had two babies). This is the only medicine that has effectively helped with my MS. I have had two MRI's and I have no new or enhancing lesions. The existing ones I did have, have healed. I had the side effects for the first month but eating a fatty meal and taking an aspirin decreases them. I have no side effects now and I've been back on since 10/14. Just make sure you get your white blood cell count tested every 3 months”

Janette75 · September 26, 2016

Tecfidera (dimethyl fumarate): “I was diagnosed with MS in June 2014; and was prescribed Tecfidera. I was fine on the initial 120mg dose, but once I had to take the 240mg dose, I started having severe GI issues...vomiting, diarrhea, cramping...similar to food poisoning. I couldn't even keep water down. I stopped taking the Tecfidera for two months until my body got back to normal; then had my neurologist prescribe me one month of the 120 mg capsules before increasing to the 240mg dose; and started taking Singulair with my morning dose. It is also essential that I eat a substantial meal with fat and starch before taking the Tecfidera. I've not had any new lesions since. For me, its a great med as long as I can manage the GI side effects.”

Tabpolo · Taken for less than 1 month · June 1, 2019

Tecfidera (dimethyl fumarate): “I was diagnosed 13 years ago with RRMS, started on Rebif which nearly killed me. Crashing blood sugar, 34, passed out at work. Was on Copaxone for 12 years, all going well, until insurance said they would no longer cover. Put on Tecfidera. By week 2 vomited, severe cramping, pounding headaches, thought I was having a stroke. I stopped. My doctor wants me to try again claiming I did not give it long enough to get over the hump of the negative side effects. When the side effects are worse than the disease it treats, I am very cautious. It just doesn’t feel right. I’m speculative as to why my doctor is pushing this drug so hard when it made me feel so bad. Is it time for a new doctor, not just a new drug?”

mimosa · Taken for 1 to 2 years · September 4, 2018

Tecfidera (dimethyl fumarate): “My husband takes this after failing with Avonex and Copaxin for RRMS. Ever since he started he's had headaches, stomach aches, joint pain, and severe fatigue. He's now taking Vitamin D and Wellbutrin. Can't sleep through the night because of pain and can't stay awake because of the fatigue. Can't do much exercise or activities due to the headaches. Only good thing was it stopped the progression of lesions. But what good is that when you don't have quality of life?”

Tecfidera (dimethyl fumarate): “I was diagnosed with MS about 3 months ago. My MS is mild so I could try weaker drugs which are usually injections (every other day). But I hate needles so my doctor prescribed tecfidera for me. It has been really good for me so far with almost no side effects. ”

Tecfidera (dimethyl fumarate): “I have been diagnosed since 5/13. I have been on tecfidEra al.osteoporosis the whole time. I have had no growth in my lesions and no new lesions at all. I was recently taken off my meds to see if I have any relapses and where my disease is....I feel like this is a wonderful medication. Also they had a program to make the meds reasonable or free if needed. Would definitely refer this medication. My cousin used to have to go get 5 hour treatments for her MS. grateful this kind of med is out there.”

Doesnt matter · Taken for 1 to 6 months · December 21, 2017

Tecfidera (dimethyl fumarate): “Ok so was given my first drug and my last for now. I had hair loss extreme balance issues, no stomach cramps etc the most common. But after 3 months taking this I got very severe joint pains that moved from one area of my body to another on a daily basis. After I stopped the drug the joint pain continued nearly 3 weeks, then stopped and I threw drugs away. It was confirmed after tests at my drs and hospital it was the drug. I have never experienced pain like it. Not a common side effect but a side effect all the same. Now I' m on no drug I feel normal like my old self. How interesting hardly any negative comments on here? Or there are plenty but not been published!”
