I have taken victoza (liraglutide) but had 2 stop due to horrible nausea, I want 2 try byetta wondering if it causes less nausea or is it just as bad?

Probably but try. Exanatide (Byetta) is in the same class of drug as liraglutide (Victoza and Saxenda) but slightly different chemically. These slight differences may make all the difference in side effects even though the potential may be the same. Worth a try.
U have to try. You really have to try to know.Let your md help you!
