No, you should not substitute these medications without consulting your doctor. While both contain the same amount of metformin (1000 mg), they contain different primary active ingredients to control your blood sugar. Your original medication contains sitagliptin (50 mg), whereas the other contains teneligliptin (20 mg). Even though both sitagliptin and teneligliptin belong to the same class of drugs, they are different medicines with different dosing strengths. Switching between them requires your doctor's evaluation to ensure your blood sugar remains safely and effectively controlled. Please consult your prescriber before changing your medicine.

Yes, you can safely substitute your morning medication with another brand, provided it contains the exact same active ingredients in the same strengths: Teneligliptin 20mg and Metformin 500mg. Substituting discontinued brands with equivalent alternatives is a very common and safe practice, and it will keep your blood sugar well-controlled. Please consult your pharmacist or doctor so they can recommend a high-quality alternative brand and update your prescription records. Continue taking your evening medication as scheduled. There is no need to worry, as your treatment remains highly effective.

No, you should not change your dose on your own, as it may affect your blood sugar control. Zita Met Plus 20/500 Tablet contains a lower dose of Teneligliptin than Zita Met 50/500 Tablet, so you should consult your doctor before switching. Your doctor can guide you on the correct dose or suggest an alternative if needed.

You should follow a structured diet plan along with your medication to help improve blood sugar control. Eat regular meals with controlled portions, focus on whole grains, vegetables, pulses, and lean proteins, and avoid refined carbohydrates, sugary drinks, and fried foods. Regular blood sugar monitoring and guidance from a doctor or dietitian will help you better manage your diabetes.

You should not switch from Zita Met Plus 20/1000 to 20/500 without medical advice, as this halves the metformin dose and may worsen blood sugar control. Please consult your doctor, who will decide based on your blood sugar readings and HbA1c levels.
