Hi, I started taking Januvia approx. 3 months ago. Around the time I started taking this new drug, I started getting very bad hives. The allergist said in no way could it be from a drug. I was watching t.v. this evening when a commercial for Januvia came on and they said hives are a serious side effect and if you are experiencing rthis, call your doctor right away. Has anyone else out there had hives after taking Januvia? It also made me feel like I have a cold that will not go away.
