My husband has been on the Bydureon Exenatide 2mg for 4 weeks, For 24 to 48 hours he is a complete write off, Nausea, Chronic headaches, Just feeling crap, Needle site pain with red itchy welts which he still has from the first needle site, I have read where both reactions can pass and stay permanently. Can someone who has been on this medication please help, advise would be really helpful. My husband is ready to throw the towel in on this product.
