Who can and cannot take sitagliptin

This medicine is not used to treat type 1 diabetes (when your body does not produce insulin).

Sitagliptin is not suitable for some people. To make sure it's safe for you, tell your doctor if you:

• have ever had an allergic reaction to sitagliptin or any other medicine
• have problems with your pancreas
• have gallstones or very high levels of triglycerides (a type of fat) in your blood
• are a heavy drinker or dependent on alcohol
• have ever had any problems with your kidneys
• are pregnant or breastfeeding, or trying to get pregnant
