Hi from 2004 im with diabete 2 im using diabos 5 mg twice a day and metformin 850 mg so is it better to use insuline or the medicaments im usin?

Depends on A1c: If your sugars are well controlled on your current medications, meaning your hemoglobin A1c is less than 7, then your current regimen is good. If not you may have better luck with insulin. There is no best treatment for diabetes. What is important is that you have good control with the least side effects possible.

Anti diabetic meds: If the diabetes is controlled with the oral medication, there is no need for insulin at this time. Type 2 diabetes over the period of time may need insulin to be part of the treatment regimen.

The best dose: of metformin is 1000 mg twice a day. The glibenclamide dose is the maximum appropriate dose, Other non-insulin treatments are available, as is insulin. It depends upon multiple factors that you need to discuss w/your doctor, There is no universal treatment.
