Lactic acidosis can occur due to metformin accumulation. The risk increases with conditions such as sepsis, dehydration, excess alcohol intake, hepatic impairment, renal impairment, and acute congestive heart failure. Symptoms include malaise, myalgias, respiratory distress, increasing somnolence, and nonspecific abdominal distress. Laboratory abnormalities include low pH, increased anion gap, and elevated blood lactate. If acidosis is suspected, discontinue repaglinide and metformin hydrochloride tablets and hospitalize the patient immediately .
Repaglinide and metformin combination is used to treat high blood sugar levels caused by a type of diabetes mellitus (sugar diabetes) called type 2 diabetes. In type 2 diabetes, your body does not work properly to store excess sugar and the sugar remains in your bloodstream. Chronic high blood sugar can lead to serious health problems in the future .
Proper diet is the first step in managing type 2 diabetes, but often medicines are needed to help your body. Repaglinide causes your pancreas to release more insulin into the blood stream. Metformin reduces the absorption of sugar, reduces the release of stored sugar from the liver, and helps your body's cells use sugar better .
