Sitagliptin is typically taken once a day, with or without food. It can be used alone or in combination with other diabetes medications, such as metformin. The dosage of sitagliptin will depend on the patient’s age, kidney function, and other medications they may be taking.
Common side effects of sitagliptin may include upper respiratory tract infections, headache, and diarrhea. Rare but serious side effects may include severe joint pain, pancreatitis, and allergic reactions.
