The report shows high blood glucose despite metformin and sitagliptin:
- Fasting blood sugar: 198 mg/dL
Usual target for many non-pregnant adults with diabetes is about 80-130 mg/dL before meals. - Post-lunch blood sugar: 230 mg/dL
Usual target is generally below 180 mg/dL at 1-2 hours after starting a meal. - Urine sugar reported as N/R, but this does not rule out high blood glucose.
This suggests that diabetes is not adequately controlled at present. Please arrange a review with the treating physician or diabetologist soon, ideally within a few days. Do not increase or add medicines on your own.
At the visit, ask for:
- HbA1c - shows average sugar control over about 3 months. For many adults, the goal is below 7%, individualized to the person.
- Serum creatinine/eGFR - needed to check kidney function and whether metformin and the sitagliptin dose are appropriate. Sitagliptin generally needs dose adjustment when kidney function is reduced.
- Urine albumin-creatinine ratio, blood pressure, lipid profile, eye and foot assessment.
The doctor may check adherence, meal pattern, medication doses, kidney function, and decide whether the current medicines need adjustment or whether a different/additional diabetes medicine is appropriate. Current ADA standards support individualized treatment based on HbA1c, weight, kidney disease, heart disease, cost, and hypoglycemia risk, not glucose values alone (ADA 2026 standards).
Seek urgent medical care today if there is vomiting, severe weakness, confusion, deep/rapid breathing, abdominal pain, dehydration, fever/infection, or glucose repeatedly above 300 mg/dL.
Until reviewed: take prescribed medication regularly, avoid sugary drinks/sweets and large rice/maida portions, do not skip meals, and monitor fasting plus 2-hour post-meal glucose if a glucometer is available.

ADA Standards of Care 2026 pharmacologic treatment A1C 1.5% above goal initial combination therapy insulin A1C 10
For most adults, the usual HbA1c goal is <7%, but it should be individualized.
Because he is already taking metformin plus sitagliptin, an HbA1c result above 7% should prompt a treatment review. A practical guide:
| HbA1c | Usual implication |
|---|---|
| <7% | Usually continue current plan if home glucose readings are acceptable. |
| 7-8% | Reinforce diet, activity, correct medication use, and check whether doses and kidney function are appropriate. If persistently above target, treatment adjustment is often needed. |
| ≥8.5% | This is about 1.5% above a 7% target. Guidelines say many people will need a more potent or additional glucose-lowering treatment. |
| ≥9% | Strong reason to intensify treatment promptly rather than wait several months, especially with fasting sugars near 200 mg/dL. |
| >10% | Insulin should be considered, particularly if there are symptoms such as excessive urination/thirst, weight loss, dehydration, or random glucose ≥300 mg/dL. |
So, for this patient, HbA1c ≥8.5% would clearly be a level likely to change the treatment plan, and ≥9% warrants prompt physician review. The current fasting value of 198 mg/dL and post-lunch 230 mg/dL make an HbA1c above goal quite likely, but HbA1c is needed to confirm the 3-month average.
The ADA notes that when HbA1c is ≥1.5% above the individual target, dual or more potent therapy is often needed; insulin is commonly considered for HbA1c >10%, glucose ≥300 mg/dL, hyperglycemic symptoms, or unintended weight loss (ADA pharmacologic guidance).

FDA metformin prescribing information eGFR 30 45 dose renal function
It may be appropriate, but only if the prescribing doctor confirms it. Do not add metformin 500 mg at night yourself.
Before increasing metformin, check:
- Current metformin dose and formulation: regular versus extended-release
- Creatinine/eGFR kidney test
- Any vomiting, diarrhea, dehydration, heavy alcohol use, severe liver/heart illness, or recent contrast CT/angiography
For many people with normal kidney function, metformin is taken with food, and a night dose may be used to improve fasting glucose. But with fasting glucose 198 mg/dL despite metformin plus sitagliptin, simply adding 500 mg may not be enough. The HbA1c, current doses, adherence, kidney function, body weight, and any heart or kidney disease should determine the next medicine change.
Do not start or increase metformin if:
- eGFR <30 mL/min/1.73 m²: metformin should be stopped.
- eGFR 30-45: starting/increasing is generally not recommended without specific clinician assessment.
- You are acutely unwell or dehydrated, have significant vomiting/diarrhea, or are scheduled for iodinated contrast imaging.
GI effects such as nausea, loose stools, and abdominal discomfort are common after rapid dose increases. Taking it with the evening meal and gradual titration can reduce this.
Please share the exact current tablet names, strengths, and timing plus the latest creatinine/eGFR if available. The metformin prescribing guidance requires kidney-function assessment before dose decisions.
