From the Guidelines

Januvia (sitagliptin) 25mg is typically prescribed once daily, not twice a day. The standard dosing for Januvia is a single daily dose, regardless of whether the patient is taking the 25mg, 50mg, or 100mg strength. The 25mg dose is usually recommended for patients with moderate to severe kidney impairment (with creatinine clearance less than 50 mL/min) or those on dialysis, as indicated in the most recent guidelines 1. Januvia works by inhibiting the DPP-4 enzyme, which increases incretin hormone levels that help regulate blood glucose throughout the day. The medication has a long half-life, which allows for effective blood sugar control with just one dose per day. Patients should take Januvia at the same time each day with or without food. If you've been instructed to take it twice daily, you should consult with your healthcare provider as this would be an unusual dosing regimen for this medication, and the most recent evidence does not support twice-daily dosing 1. Some key points to consider when prescribing Januvia include:

  • Dose adjustment required based on kidney function (sitagliptin) 1
  • No dose adjustment required for linagliptin 1
  • Pancreatitis has been reported, but causality has not been established, and the medication should be discontinued if pancreatitis is suspected 1 It's essential to follow the recommended dosing regimen to minimize potential side effects and maximize the medication's effectiveness in managing blood sugar levels.
