Cases of inflammation of the pancreas (pancreatitis) have been reported in patients receiving Sitagliptin/Metformin (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/Metformin.

Sitagliptin/Metformin may cause a very rare, but very serious side effect called lactic acidosis, particularly if your kidneys are not working properly. The risk of developing lactic acidosis is also increased with uncontrolled diabetes, serious infections, prolonged fasting or alcohol intake, dehydration (see further information below), liver problems and any medical conditions in which a part of the body has a reduced supply of oxygen (such as acute severe heart disease).

If any of the above apply to you, talk to your doctor for further instructions.

Stop taking Sitagliptin/Metformin for a short time if you have a condition that may be associated with dehydration (significant loss of body fluids) such as severe vomiting, diarrhoea, fever, exposure to heat or if you drink less fluid than normal. Talk to your doctor for further instructions.

Stop taking Sitagliptin/Metformin and contact a doctor or the nearest hospital immediately if you experience some of the symptoms of lactic acidosis, as this condition may lead to coma.

Symptoms of lactic acidosis include:

• vomiting
• stomach ache (abdominal pain)
• muscle cramps
• a general feeling of not being well with severe tiredness
• difficulty in breathing
• reduced body temperature and heartbeat

Lactic acidosis is a medical emergency and must be treated in a hospital.

Talk to your doctor or pharmacist before taking Sitagliptin/Metformin:

• if you have or have had a disease of the pancreas (such as pancreatitis)
• if you have or have had 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)
• if you have type 1 diabetes. This is sometimes called insulin-dependent diabetes
• if you have or have had an allergic reaction to sitagliptin, metformin, or Sitagliptin/Metformin: (see section 4)
• if you are taking a sulphonylurea or insulin, diabetes medicines, together with Sitagliptin/Metformin: as you may experience low blood sugar levels (hypoglycaemia). Your doctor may reduce the dose of your sulphonylurea or insulin.

If you need to have major surgery, you must stop taking Sitagliptin/Metformin during and for some time after the procedure. Your doctor will decide when you must stop and when to restart your treatment with Sitagliptin/Metformin.

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Sitagliptin/Metformin

Your doctor will decide when you must stop and when to restart your treatment with Sitagliptin/Metformin.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. You may need more frequent blood glucose and kidney function tests, or your doctor may need to adjust the dosage of Sitagliptin/Metformin. It is especially important to mention the following:

• medicines (taken by mouth, inhalation, or injection) used to treat diseases that involve inflammation, like asthma and arthritis (corticosteroids)
• medicines which increase urine production (diuretics)

• digoxin (to treat irregular heartbeat and other heart problems). The level of digoxin in your blood may need to be checked if taking with Sitagliptin/Metformin.

Avoid excessive alcohol intake while taking Sitagliptin/Metformin since this may increase the risk of lactic acidosis (see section “Warnings and precautions”).
