Warnings and precautions
Cases of inflammation of the pancreas (pancreatitis) have been reported in patients receiving Treviamet (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 Janumet.
Risk of lactic acidosis
Treviamet 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 Treviamet 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 Treviamet 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
– stomachache (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 Janumet:
– 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 Janumet (see section 4)
– if you are taking a sulphonylurea or insulin, diabetes medicines, together with Treviamet, as you may experience low blood sugar levels (hypoglycaemia). Your doctor may reduce the dose of your sulphonylurea or insulin
