I just started my 4th month on Byetta (3 months at 10mcg). I also take 2000 mg of Metformin XR daily. Has anyone else developed what may or may not be an allergic reaction to Byetta? I developed hives and itching on my neck and lower face a month ago, and I still have the itchiness. Other possible causes are having taken an antibiotic and after having tried a new skin cream. During my first month of Byetta, hives developed at injection sites. That has not occurred since.
My other question: when you develop nausea, does it occur suddenly and last for a minute or two, then disappear as quickly? This has happened to me about three times. The last time occurred at work immediately after lunch. I only ate a chicken salad (not fried chicken) and an orange.
