Dagliflozin is generally recommended to be given orally once daily. The recommended starting dose of dagliflozin is 5 mg taken in the morning, once daily, by mouth. The dose may be increased to 10 mg once daily for patients who tolerate 5 mg once daily and require enhanced glycemic control. Dagliflozin lowers blood glucose by inhibiting sodium-glucose cotransporter protein 2 expressed in renal proximal tubules, reducing renal glucose reabsorption and increasing urinary glucose excretion. Note that this drug is contraindicated in people who are allergic to this drug, as well as those with severe renal impairment, end-stage renal disease, and those who need dialysis. It is recommended to decide how to use Dagliflozin under the guidance of a professional doctor and according to the individual’s physical condition, blood sugar and other conditions. Do not use it on your own to avoid adverse reactions.
