Patient leaflet - Sitagliptin 25 mg/ml oral solution
1. What Sitagliptin is and what it is used for
The name of this medicine is Sitagliptin 25 mg/ml oral solution (called Sitagliptin throughout this leaflet). It contains the active substance sitagliptin which is a member of a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors) that lowers blood sugar levels in adult patients with type 2 diabetes mellitus. This medicine helps to increase the levels of insulin produced after a meal and decreases the amount of sugar made by the body.
Your doctor has prescribed this medicine to help lower your blood sugar, which is too high because of your type 2 diabetes. This medicine can be used alone or in combination with certain other medicines (insulin, metformin, sulphonylureas, or glitazones) that lower blood sugar, which you may already be taking for your diabetes together with a food and exercise plan.
What is type 2 diabetes?
Type 2 diabetes is a condition in which your body does not make enough insulin, and the insulin that your body produces does not work as well as it should. Your body can also make too much sugar.
When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems like heart disease, kidney disease, blindness, and amputation.
2. What you need to know before you take Sitagliptin
Do not take Sitagliptin
- if you are allergic to sitagliptin or
any of the other ingredients of
this medicine (listed in section 6). Warnings and precautions
Cases of inflammation of the pancreas (pancreatitis) have been reported in patients receiving
Sitagliptin (see section 4).
If you encounter blistering of the skin it may be a sign for a condition called bullous pemphigoid.
Your doctor may ask you to stop Sitagliptin.
Tell your doctor if you have or have had:
a disease of the pancreas (such

as pancreatitis)
gallstones, alcohol dependence
or very high levels of triglycerides (a form of fat) in your blood. These medical conditions can increase your chance of getting pancreatitis (see section 4).
- type 1 diabetes
- diabetic ketoacidosis
(a complication of diabetes with high blood sugar, rapid weight loss, nausea or vomiting)
any past or present
kidney problems.
an allergic reaction to Sitagliptin
(see section 4).
This medicine is unlikely to cause low blood sugar because it does not work when your blood sugar is low. However, when this medicine is used
in combination with a sulphonylurea medicine or with insulin, low blood sugar (hypoglycaemia) can occur. Your doctor may reduce the dose of your sulphonylurea or insulin medicine.
Children and adolescents
Children and adolescents below 18 years should not use this medicine. It is not effective in children and
adolescents between the ages of 10 and 17 years. It is not known if this medicine is safe and effective when used in children younger than 10 years.
Other medicines and Sitagliptin
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. In particular, tell your doctor if you are taking digoxin (a medicine used
to treat irregular heart beat and other heart problems). The level of digoxin in your blood may need to be checked if taking with Sitagliptin. Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask
your doctor or pharmacist for advice before taking this medicine. You should not take this medicine during pregnancy.
It is not known if this medicine passes into breast milk. You should not take this medicine if you are breast-feeding or plan to breast-feed. Driving and using machines
This medicine has no or negligible influence on the ability to drive and use machines. However, dizziness and drowsiness have been reported, which may affect your ability to drive or use machines.
Taking this medicine in combination with medicines called sulphonylureas or with insulin can cause hypoglycaemia, which may affect your ability to drive and use machines or work without safe foothold. Excipients with known effect: Sodium methyl parahydroxybenzoate (E219): May cause allergic reactions (possibly delayed).
Forest fruits flavour containing benzyl alcohol (E1519): may cause allergic reactions. Ask your doctor or pharmacist for advice if you are pregnant or breast-feeding or have a liver or kidney disease. This is because large amounts of benzyl alcohol can build-up in your body and may cause side effects (called “metabolic acidosis”), ethyl alcohol (E1510); the small amount of alcohol on this medicine will not have any noticeable effects.
Sitagliptin contains less than 1 mmol sodium (23 mg) per 1 ml, that is to say essentially “sodium-free”.
