Yes, Zita Met Plus 20/1000 Tablet (Metformin and Teneligliptin) is suitable for long-term control of type 2 diabetes when taken under a doctor?s supervision. It helps lower blood sugar by improving insulin action and reducing sugar production in the body. Many people use this combination safely for several years with good results. However, the suitability of this medicine depends on how well your blood sugar is controlled, your kidney and liver function, weight, diet, exercise habits, and whether you have any side effects. Regular monitoring is important because diabetes treatment may need to be adjusted over time. Your doctor may advise periodic tests, such as HbA1c, kidney function tests, liver function tests, and vitamin B12 levels. You should continue taking the medicine regularly unless your doctor advises otherwise. Along with tablets, maintaining a healthy diet, regular physical activity, proper sleep, and weight control are equally important for long-term diabetes management. If you notice symptoms such as frequent low blood sugar episodes, stomach upset, weakness, or swelling, consult your doctor for review of the medicine and dosage.
