It prevents the kidneys from reabsorbing blood sugar. Farxiga also allows the removal of excess blood sugar through urine. Farxiga helps in slowing down or restricting the production of a protein, SGLT2. SGLT2 is present in the kidneys and prevents them from reabsorbing blood sugar. The absence of SGLT2 enables the kidneys to release the sugar. Farxiga helps in the removal of excess sugar through urine.
Dosage of Farxiga
Farxiga is available in 5 mg and 10 mg tablets. Estimated glomerular filtration rate (eGFR) is the basis of recommendation of the dosage of Farxiga. The doctors recommend Farxiga 5 mg tablet once a day as the starting dose to lower the blood sugar levels if your eGFR is 45 or more. People having eGFR 25 or more but less than 45 can take 10 mg of Dapagliflozin orally once a day. The doctors do not prescribe Farxiga to patients having eGFR less than 25.
