Byetta and iching
Found on a diabetes newsgroup, addresses some of the folk who have had this
side effect.
"I also take Byetta. The only side effect that I suffered, other than the
slight nausea/decrease in appetite the first 6 months (and a subsequent 18
pound weight loss) was an allergic reaction to the preservatives in the
medicine. It created a welt similar to a very large hornet sting every
time I injected it, and it itched like the dickens! My endo contacted the
company, who sent a representative down to counsel. It appears that about
1 in 100 people have that reaction, and the simplest solution is longer
needles. The reaction is only to the outer layer of skin, not inside, so
depositing the medicine further inside meant a smaller reaction. It still
itches slightly after an injection, but I no longer feel the need to rip my
skin apart, and the small welt goes away long before the next time I
inject. The needles weren’t that much longer (yay). I have had mixed
feelings about taking it."
