Farxiga treats type 2 diabetes. Farxiga can cause yeast infections and urinary tract infections.
Farxiga is a prescription medication used to control blood sugar levels in people with type 2 diabetes. Farxiga is part of a new class of drugs that work in the kidney to block a protein called SGLT2. By blocking this protein, the drug can remove excess glucose (sugar) through the urine, which helps lower blood sugar levels.
This medication comes in tablet form and is usually taken once daily. Farxiga tablets should be swallowed whole and can be taken with or without food.
Common side effects of Farxiga include low blood sugar (hypoglycemia), yeast infections of the penis or vagina, and backache.
