Nocturia & Januvia Intake?

Nocturia & Januvia

Nocturia & Januvia




Quick Answer
Waking six times each night to urinate is significant and deserves further evaluation. Nocturia is not listed as a common adverse effect of Januvia (sitagliptin), and changing the time of the dose may not solve it. Januvia is usually taken once daily, with or without food, at a consistent time. Possible causes include high nighttime glucose, an overactive or incompletely emptying bladder, enlarged prostate, sleep apnea, leg swelling, kidney or heart problems, and medicines such as diuretics.


Answer by Dr. Albana Greca, MD, MMedSc



Hi there,



Your HbA1c of 6.3% suggests good average glucose control for many adults with type 2 diabetes. However, HbA1c does not show every overnight rise or explain all urinary symptoms. Our guide to understanding HbA1c explains why daily readings and HbA1c provide different information.



Is Januvia Causing the Nocturia?



Januvia is a DPP-4 inhibitor. It is not a diuretic and does not lower glucose by making the kidneys release sugar into the urine. Nocturia is not listed among its common adverse reactions.



The usual dose is taken once daily with or without food. Morning or evening dosing is generally acceptable, provided you take it consistently and follow your prescription. Do not stop or change Januvia without speaking with your doctor. See our overview of Januvia and other DPP-4 medicines.



What Else Can Cause Nocturia?



A negative urine test makes infection less likely, but it does not rule out other causes. Your doctor may consider:




  • High glucose during the evening or overnight

  • An overactive bladder or incomplete bladder emptying

  • Enlarged prostate in men, especially with a weak urine stream

  • Sleep apnea, particularly with snoring, gasping, or daytime sleepiness

  • Leg swelling that returns fluid to the circulation after lying down

  • Kidney disease, heart problems, or abnormal calcium levels

  • Diuretics and some other medicines



Long-standing diabetes can also affect the nerves and muscles controlling the bladder. Read more about diabetic autonomic neuropathy and bladder symptoms.



What Should Be Checked?



Keep a three-day bladder diary recording when and how much you drink, each urination, approximate urine volume, bedtime, awakenings, and glucose readings.



Checking glucose at bedtime and when you wake to urinate may show whether high blood sugar is contributing. Compare your results with our blood sugar level chart.



Ask your healthcare provider to review your kidney function, medicines, blood pressure, leg swelling, bladder emptying, and symptoms of sleep apnea. If you are male, a prostate assessment may be appropriate. A urologist may recommend additional bladder testing.



Fluid and Evening Habits



Three 16-ounce bottles provide about 1.4 litres of fluid before counting food and other drinks. There is no single two-litre requirement that is safe for everyone. Fluid needs vary with body size, climate, activity, kidney function, heart health, and medicines.




  • Drink regularly during the day rather than becoming dehydrated.

  • Reduce larger drinks during the two to four hours before bed.

  • Limit evening caffeine and alcohol.

  • Empty your bladder immediately before sleeping.

  • If your legs swell, ask whether elevating them earlier in the evening is suitable.




Important: Do not deliberately dehydrate yourself. Concentrated urine may irritate the bladder, and dehydration can worsen kidney function and blood glucose.


My Advice



Because you are waking as many as six times nightly and experiencing daytime fatigue, return to your healthcare provider for a focused nocturia assessment rather than assuming Januvia is responsible.



Your good HbA1c is reassuring, but it does not exclude a bladder, prostate, sleep, kidney, or circulation problem.



Do not replace Januvia with herbal or Ayurvedic products based on online comments. Diabetes medicines and supplements may cause side effects or interact with other treatment, as explained in our diabetes medication safety guide.




Seek prompt care for blood in the urine, fever, burning pain, inability to urinate, severe lower abdominal pain, new leg swelling, shortness of breath, extreme thirst, or repeatedly very high glucose.


Hope this helps.
