My fasting blood sugar is staying around 300 will this tablet help bring it down?

A fasting sugar of 300 is quite high and really needs prompt medical attention rather than waiting to see how a single tablet performs. This combination dapagliflozin, metformin, and sitagliptin together is a strong, extended-release option for type 2 diabetes and can help bring numbers down significantly over time, but at this level your doctor needs to reassess your treatment directly and possibly adjust things quickly. Please don't wait get in touch with your doctor as soon as possible.
