Both Soliqua and Xultophy combine a long-acting insulin with a GLP-1 agonist: Xultopy brings together Tresiba (insulin degludec) and Victoza (liraglutide), while Soliqua combines Lantus (insulin glargine) with Adlyxin (lixisenatide). When used with diet and exercise for the treatment of type 2 diabetes, these agents can help you control blood sugar, insulin levels, and digestion and may help you lose weight.
