Combining a GLP-1 receptor agonist with a DPP-4 inhibitor (add-on therapy) provides better glycemic control than switching, without a significant increase in adverse events, contrary to theoretical predictions of antagonism.
If you are on a DPP-4 inhibitor and metformin but still need better blood sugar control, adding a GLP-1RA might be an option, though switching is more common. One study suggested this combination worked well without extra side effects, but it is not the standard approach. Discuss with your doctor if this complex regimen is right for you.
The results of this study suggest that adding a GLP-1RA to sitagliptin and metformin provides better glycemic control without a significant increase in adverse events.

- Switching patients from DPP-4 inhibitors to GLP-1 receptor agonists improves glycemic control and weight loss, although it may transiently increase gastrointestinal adverse events.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
