Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Sitagliptin (Januvia) and dapagliflozin (Farxiga) are both oral medications used to treat Type 2 diabetes, but they belong to different medication classes. Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor, while dapagliflozin is a sodium-glucose cotransporter 2 (SGLT2) inhibitor. Sitagliptin is taken once daily at a dose of 25 mg to 100 mg, whereas dapagliflozin is started at 5 mg daily and can be increased to 10 mg daily. Dapagliflozin is also approved to lower the risk of heart failure hospitalization and to help with chronic kidney disease, which sitagliptin is not. While sitagliptin is not known to affect body weight, dapagliflozin may cause weight loss. Common side effects of sitagliptin include a runny nose and sore throat, while dapagliflozin can cause urinary tract infections, yeast infections, and increased urination. Both medications can interact with other diabetes treatments, potentially causing low blood sugar.
