The use of the diabetes drug Byetta has been linked to the development of serious and potentially fatal pancreatitis. The FDA issued alerts in October 2007 and August 2008 warning doctors about the possible link between side effects of Byetta and pancreatitis.
BYETTA LAWSUIT STATUS: Based on reports of acute, hemorrhagic and necrotizing pancreatitis among users, potential Byetta lawsuits are being considered and reviewed by lawyers.
>>REVIEW A CASE WITH A BYETTA LAWYER<<
MANUFACTURERS: Amylin Pharmaceuticals, Inc. and Eli Lilly & Co.
OVERVIEW: Byetta (exenatide) is a type 2 diabetes drug which was approved by the FDA in April 2005 to help reduce blood sugar levels. It is a subcutaneous injection administered twice a day, which has been taken by over 700,000 people in the United States.
The drug belongs to a class of drugs known as incretin mimetics, which mimic the action of endogenous incretin hormones like GIP and GLP-1, which are found in the gastrointestinal tract. Byetta lowers blood glucose levels by stimulating insulin secretion from pancreatic cells.
BYETTA PANCREATITIS SIDE EFFECTS: In October 2007, the FDA issued an alert about an association between Byetta and pancreatitis, which could lead to fatal injuries for some users. At that time, the FDA had received at least 30 reports of acute pancreatitis associated with Byetta, and the manufacturer agreed to update the warning label about this potential Byetta side effect.
In August 2008, a second FDA alert was issued to inform healthcare providers about six additional cases of necrotizing pancreatitis or hemorrhagic pancreatitis which had been reported among Byetta users. At least two of these cases resulted in fatal injuries for the user.
Pancreatitis is an inflammation of the pancreas, which can cause symptoms like:
- Severe upper abdominal pain which may radiate through the back
- Nausea and Vomiting
- High or Low Blood Pressure
- Elevated Heart or Respiratory Rates
Hemorrhagic pancreatitis is a severe form of the condition where massive erosion of blood vessels can lead to severe bleeding.
Necrotizing pancreatitis involves tissue damage, which leads to the release of toxins and enzymes into the blood stream and may cause multi-organ failure and death.
The FDA has recommended that healthcare providers monitor their patients who are receiving Byetta and the drug should be stopped if pancreatitis is suspected. If someone develops pancreatitis or has a history of the condition, the FDA indicates that a different diabetes treatment should be used. Individuals receiving the drug have also been urged to report any potential Byetta side effects, including unexplained severe abdominal pain, either with or without bleeding.

Comment by Sonji on 8 October 2008:
I started Byetta in May 2008. I thought this was a wonder drug. My blood sugars were normal for a change. However, in June 2008, I developed severe abdominal pain and was hospitalized. I was dx with a small bowel obstruction and pancreatitis. The hospitalist stopped my byetta because of the reports he had heard regarding the use of Byetta and pancreatitis. Four month later, I still have GI problems and have been told this is probaly due to the Byetta.

around october 2003 my dr. put me on byetta. In February 2005 I had to have my right kidney removed andon May 27, 2007 i had to go on dialysis.
Comment by Brigitte on 22 October 2008:
In 2006-2007 I was on Byetta. At first it really helped my blood sugar and I ate less. But I was always sick with abdominal pain which I thought it would pass but never did. I still have GI problems to this day.

Comment by Jennifer on 12 November 2008:
I began taking Byetta in December of 2007, and continued to take it until April of 2008. Though it worked wonders at lowering my blood sugar levels in combination with my Glipizide, it made me sick to my stomach with serious abdominal pain. In August of this year my pills completely stopped working, causing my sugar levels to soar into the 500’s on nearly a daily basis, and I was informed that my pancreas had completely stopped working, and there are threats of dialysis in the very near future. I am going to have additional tests run this week, but I need to know if anyone else has had issues like this after taking this drug?
Comment by patty on 13 November 2008:
I started taking byetta in july of 07. It worked wonderful until aug of 08 when i developed severe pain and was taken to a local hospital where they transferred me to a bigger hospital. I am still having pain of and on and have to take morphine when it is severe.
Comment by Shelly on 1 December 2008:
I started Byetta in 2006 and stop taking it about four months ago. I was never told about the pancreatitis issues. My doctor took me off of it because my blood sugar was well maintained. For a little over a year I have been having severe abdonminal pain and abnormal bloodwork. I was told my liver and pancreas levels were high. I have under gone several tests. Now it looks like I have liver disease. I’m having a liver biospy done this coming Thursday to see how bad it is. I’m 34 and what most doctors consider a good diabetic. My A1C hasn’t been any higher than 6.7 in a year and a half. Now I’m thinking that their is a link to my liver issues. Has anyone else been having liver issues? I was also told that my gall bladder is involved. So I’m having issues with three organs. I had a full cardio work up about three months ago. Everything is fine. I only failed the EKG. Since taking Byetta I have been having heart palpations. I’m glad I’m no longer taking Byetta.

Comment by patricia on 8 December 2008:
in 2006 i was precribed byetta. i began to take it even with the warning from my dr. about the side effects. he did say stay with it because in timr the symptoms will probably go away. that is what i did, every side effect listed i experienced. i was sick as a dog, lost a great deal of wehit, could not keep anything down, the abdominal was awful, i mostely stayed in bed then i would take the second dose, the onslaught continued. after being told by my dr. to hang on a few more weeks i did but got no better. in 2007 i stoped taking byetta for three months then i was told to begin again. again i suffered the same symptoms but with a vengence. after 6 mo. i finally told my dr. i could not do this anymore. now i take lantus, but my sugars are difficult to keep at a normal range.
Comment by Richard on 15 December 2008:
I took byetta for 14 months and had excellent control over my diabetes as well as lost 50 pounds. Six weeks ago my endocrinologist d/c my byetta and prescribed insulin due to extremely elevated liver enzynes. SMy liver levels have now gotten back to almost normal. I also had to d/c lipitor at the same time so I’m uncertain which or if both are related.
Comment by Bill on 19 December 2008:
I have taken Byetta since 2005 when it was first approved. I have never had any problems with nausia and my blood sugar has been well controled. I have had some heart problems over the past three years I have had to have stints put in on two occassions as well as triple by-pass surgery. I had never had any heart problems in my life, also my chlostriol levels have always been excellent. I am not a Dr. but, I feel that all of tthese problems were brought on by the use of Byetta/
Comment by Stu on 30 December 2008:
I’m afraid to eat anything because the Byetta shot starts a radiating burning feeling in my stomach within 1 hour followed my throwing up shortly there after.
From 5:15pm last night when I took the shot until around 3:30am I had this constant burning feeling throughout my body just like when I was taking the Chemo treatments.
Bye Bye BYETTA Before this stuff frys my insides out!!!
Comment by Jarrod on 5 January 2009:

Comment by S Smart on 9 January 2009:
I took for 3 months everyday vomiting and pain. My doctor believed in the drug and did not want to take me off of it. I finally told him there was no way I was continuing to take this medicine. I still have problems with my GI tract.
Comment by angela on 17 January 2009:
I never lost a pound on the byettam, as I was promised. It did control my appetite. I was naseus when I first started but then that subsided. I am afraid to go back to the dr. I did stop taking my byetta about 3 mnths ago because I hated giving myself shots.
Comment by Sharon on 19 January 2009:
In July of 2007 I was prescribed Byetta and began to use it. It worked extremely well at controlling my blood sugars, however I was constantly sick to my stomach with diarrhea constantly. I used this drug until November of the same year. I could no longer take the bad side effects and called my doctor. He told me to immediately stop using the Byetta and he prescribed Januvia. Until about three weeks ago I had this feeling of being extremely full all the time. I’m just wondering if this could have been some lasting side effects from the drug. Has anyone else experienced this?
Comment by Doris on 21 January 2009:
I started taking Byetta in March 27th of 2008 and stopped taking it soon after. While I was on it and even after I stopped taking it I experience severe abdominal pain, nausea, heart palpatations, and now my stomach does not empty properly. It may have even caused a bacterial infection I had soon after taking it. I stopped taking it because I couldn’t handle the side effects anymore and I’m still having problems with my stomach and GI tract.
Comment by Shari on 26 January 2009:
I began taking Byetta in September 2005. I began with the .5mcg dosage with some nausea for a few months and occassional vomitting but eventually my body got used to it and my sugar was controlled and I began to lose weight as well.. Then in April of 2008, my blood pressure began to go up despite my BP meds as did my weight with a lot of waterweight gains so my doctor increased my BP med and increased my Byetta dosage to 10mcg. That dosage made me deathly sick…mostly in the evenings. I rarely kept anything down so I made the mistake of eating very little at night and eating my bigger meal at noon which defeated the purpose of the Byetta. I lost the weight and my sugar was kept within acceptable range but the vomitting was wrecking my body and I was losing weight the wrong way.
My doctor took me off of Byetta last October and put me on 2 tabs of Janumet/day. It took my body a couple of months to get used to being off the Byetta and on the Janumet, but my sugar is stable and I have not gained back the weight I lost plus my BP has remained controlled. I do not miss the Byetta. It was definitely not for me…I had enough of that nausea with 3 pregnancies…I didn’t not want to have to put up with it for the rest of my life.

Comment by Donald on 1 February 2009:
I took 5 shots of Byetta 5mcg - on the third day the heartburn and abdominal pain and fatigue were so severe for that I broke out in a full body sweat. I was never informed of this side effect before being prescribed. So I continued for 2 more days and thank God my wife is an RN - I went to the hospital and my LFT’s (liver Function tests) were extremely abnormal - That was only one day ago - I have to have the blood tests rechecked in 6 days to see if they are going back to normal…ALT normal 50 - mine 1068…..Please do NOT take this drug

I took byetta for two years and recently rushed to hospital with Renal failure.
Comment by Lynn on 5 March 2009:
I took Byette for a year and was nauseated the entire year. I would get so sick I would have to go to bed after taking it. But my sugars and A1C were under control and I lost almost 30 pounds. Then my sugars started to plunge to hypoglycemic numbers and I felt like I have never felt before, so scary, like you are dying or on fire inside. The doctor said the nausea was from acid reflux not Byetta? Horrible pain aroiund my chest and in my stomach and chronic diahrea. So why didn’t he tell me that when I asked him over and over about it? Now I have acid reflux so bad that he has me on acidphex and I am drinking organic vinegar with apple juice to try and stand it. I never had these porblems until the Byetta and now he wnat o prescribe a new thing called Symlin Pen? Because I may gain weight?
Comment by Gail on 19 March 2009:
I started Byetta in 2006. I loved it . My sugar was finally under control and I lost a few pounds. By early 2007 I started getting sick and had elevated liver enzymes.. By October of 2007 I was extremely ill , had severe abdominal pain and nausea and vomiting.A liver biopsy showed that I already had cirrhosis of the liver. I have only been diabetic for about 4 years. No where near long enough for the Diabetes to have caused this on its on.
My Nurse Practitioner feels that the byetta is the cause also.I have already notified the FDA of my story and I hope they pay attention.
Someone has to stop this madness . I belong to a diabetic support group and there are a lot of people still using this product.
My heart goes out to the families of the patients that have died. But There are many of us that are facing a death sentence because of this.
Comment by Gail on 21 March 2009:
I took Byetta and ended up with Liver damage. I urge every one that has liver damage from Byetta to e-mail the FDA so they will watch for more than pancreatic damage.All GI problems concerning Byetta should be reported to the FDA. This drug IS causing multiple problems for many people and I don’t think its going to stop any time soon.The damage doesn’t seem to improve after you stop using Byetta

My husband was on byetta over a year ago. He quit taking it due to our insurance changed and it was going to be to expensive for us. For the past 6-8 months, he has been having pain in his upper stomach and diarreah. The Dr ran tests, showed elevated liver. Ran other tests. Said he has IBS. After reading all of this, I think it has something to do with the byetta.

Comment by Dolores on 21 April 2009:
I was prescribed Byetta the summer of 2005, first 5mg and than increased to 10mg each meal (3). I had lost 25 lbs by the end of 2006, but I was feeling nauseous during that period of time, but later on 2007 I started to feel sick to my stomach and was starting to throw-up, and felt like I had heartburn. Sometimes at night I would wake up with a burning acide rushing up my throat. Byetta is not for me.
Comment by boblynn on 26 April 2009:
I began taking byetta in 2006. I had great results, weight loss and great blood A1Cs. I did have just a short time of upset stomach at the beginning, nothing I was really bothered by. In the fall of 2007, I went on a business trip to Salt Lake City, UT. As I was leaving the city I began to be ill, within a week I was in the hospital. severe projectile vomiting, low blood sugars and diarrhea (which resulted in dehydration). After several trips to emergency room for treatment for the dehydration I was finally admitted. During my hospitalization they took me off the Byetta, with little explanation. I was never really diagnosed with any illness — a few weeks later we learned that there was some water born virus in Eli UT when I was there — it was assumed this was the problem. I was run through a large number of tests including a colonoscopy and one from the other end.. I eventually got better. When in the hospital they also discovered I had extremely low blood counts which was treated with Procrit. Later, I was diagnosed as Aplastic Anemia. I also began having problems with my sodium levels (too low) a little while after I began taking byeatta. I still am on restricted liquids for this. In April of last year I suffered Acute Kidney failure and was in a coma for three days. I still have some memory loss from the coma. My kidneys operate at around 70% with a few dips to the 50% since the kidney failure. I have gained all the weight back that I lost on byeatta, and even weight loss medicine will not make my weight go down. I have constant constipation. Sometimes close to two weeks between movements and that is with taking 2 Alli 3 times a day (Dr. prescribed Olliostat which is the same thing as Alli but lots cheaper), + other meds for constipation with minimal results. I don’t know if it is related, but I have had this problem since the diarrhea stopped from illness in fall of 2008. We have practically gone broke with my medical between Fall of 2007 and Now. We have insurance, but I capped out my prescription in June of 2008 (procrit shots were costing us out of pocket $2600 a month) The prescriptions have been the biggest problem. But the lost work for both me and my husband is the worst, we are self employed so we have no sick leave or family leave. The two hospitalizations totaled 18 days alone, that doesn’t count all the times running to emergency room and Drs. (both 60 miles round trip from home.) Most of last year I was too ill to drive the distance, so husband would have to close the shop to take me to the Dr.s. I sometimes wonder if we will ever recover and rebuild the business we’ve lost as a result!
Comment by kari on 3 June 2009:
I was put on byetta last year. IT was HORRIBLE i would cry before my injections because i knew i would be violently ill. I was told by my doctor that the side effects were normal and would pass over time..but they didnt they got worse. so bad infact that i was in the emegency room weekly for massive abdominal pain wich they could not explain they tried everything right down to removing my gallbladder (wich was perfectly health) I truly belive it was due to teh byetta . still to this day i suffer from unexplained massive abdominal pain that cripples me. I would break out in massive sweats and vomit so hard that i really thought my insides were going to come out. i ultimately stopped taking it and found a new doctor. it was not normal to feel that way and my doctor pushed so hard for me to stay on it. my husband called her in a panic one night and she told him to tell me to buck up and deal with a little nausea. as i was sweating from head to toe and violently shaking as i couldnt even sip water. i truly felt as though i were dying. and to this day i still get the pain. it is an evil drug please dont take it. you will suffer.
Comment by Chris on 16 June 2009:
I took my first dose of Byetta this morning… I’m trying to get my health on track. Thank you for the information. I will discontinue the Byetta if any extreme side affect take place or the pen is exhausted (which ever comes first).
Comment by Eileen on 22 June 2009:
When my dr put me on this - i took it for about 3 months in 2006, I looked forward to it because of the hype that it would help me lose weight too- but within the 3rd month I began to feel sick to my stomach alot and my blood pressure would bottom out, after I woke up in the middle of the night freezing in the middle of the summer I went to the dr and stopped taking byetta - I still have problems with my g. i. and believe this is related to my use of byetta for the short period of time I did use it.
