Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Januvia (sitagliptin) and Invokana (canagliflozin) are both oral medications used to treat Type 2 diabetes, but they work in different ways and belong to different drug classes. Januvia is a dipeptidyl peptidase 4 (DPP-4) inhibitor that helps increase insulin levels and decrease sugar production in your body, while Invokana is a sodium-glucose co-transporter 2 (SGLT2) inhibitor that helps your kidneys remove excess sugar through urine. Januvia is typically taken once daily and does not affect body weight, whereas Invokana can cause weight loss and is also taken once daily, preferably before the first meal. Invokana has additional benefits of lowering the risk of major heart events and worsening kidney problems, which Januvia does not specifically address. However, Invokana carries a risk of genital infections and possible amputations, while Januvia may cause severe joint pain and has a rare risk of pancreatitis. Both Invokana and Januvia are only available as brand-name medications.
