pancreatitis,, After being prescribed Byetta for Type II Diabetes by a PA, I used the 5 dose size of Byetta for 30 days, then I went on 10 dose of Byetta twice a day. on a Saturday morning I had discomfort under my left breast after my AM injection, then after PM injection I began to experience severe pains under my left breast, they got progressively worse as the minutes went by, terrible pain, ended up in the emergency room, blood tests showed increased pancreatic enzymes, I was given a prescription and told to visit my GP on Monday. My GP knew what had caused it as soon as I told him I had been taking Byetta, he had other patients who had the same thing to happen. I called the mfg, they were aware of the problem, the FDA has put out a warning after I began taking the Byetta. There were no warnings about pancreatitis in the medicines I had received. Since this instance in December, I have talked with two others who had similar experiences with Byetta. I now am left with chronic pancreatic pain and am on meds for that. From what I have read have a 4% chance of developing pancreatitis cancer as a result of the attack. When you read the little infor out there about this, it appears to be pushed off as long time alcoholics who drink excessively are the ones who have had this problem with Byetta. I would estimate it has been at least 4 years since I have had a cocktail and have never been an alcoholic... BEWARE!!!
