Janumet (Metformin 500mg + Sitagliptin 50mg) itself does not typically increase creatinine levels, but it should be used cautiously if kidney function is impaired.

🩺 Creatinine and Janumet Use

• Janumet is generally avoided or used with caution in patients with kidney impairment because metformin, one of its components, is cleared by the kidneys. Impaired kidney function can lead to accumulation of metformin and increase risk of lactic acidosis, a rare but serious side effect.
• A creatinine level of 1.8 mg/dL indicates some reduction in kidney function, which is common after major surgery such as bypass. This level signals that careful monitoring and possibly adjusting diabetes medications are needed.

⚠️ Important Considerations After Bypass Surgery

• Kidney function can be affected by surgery and related factors (like medications, fluid shifts, or low blood pressure).
• Your elevated creatinine means your kidneys are currently under stress, so it is important to review all your medications, including Janumet and insulin, with your cardiologist and endocrinologist or nephrologist.
• Regular kidney function tests are recommended to monitor for any worsening.

🩺 What You Should Do Next

• Inform your doctor about your creatinine level and current medication regimen.
• Do not stop or change your medications without medical advice.
• Your doctor may adjust your dose or switch medications to safer alternatives for kidney health.

Always consult your cardiologist or an endocrinologist to ensure safe management of your diabetes and kidney function after bypass surgery.
