Disimet contains two different medications, called sitagliptin and metformin.

• Sitagliptin belongs to a class of medications called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors)
• Metformin belongs to a class of medications called biguanides.

They work together to control blood sugar levels in adult patients with a form of diabetes called “type 2 diabetes mellitus”. This medication helps to increase the levels of insulin produced after a meal and reduces the amount of sugar produced by the body.

Along with a diet and exercise, this medication helps to lower blood sugar levels. This medication can be used alone or with certain diabetes medications (insulin, sulfonylureas, or thiazolidinediones).

What is type 2 diabetes?

Type 2 diabetes is a disease in which the body does not produce enough insulin and the insulin produced by the body does not work as well as it should. The body may also produce too much sugar. When this occurs, sugar (glucose) accumulates in the blood. This can lead to serious medical problems, such as heart diseases (cardiovascular), kidney diseases (renal), blindness, and amputations.

Do not take Disimet

• if you are allergic to sitagliptin, metformin, or any of the other ingredients of this medication (listed in section 6)
• if you have severe kidney function impairment
• if you have uncontrolled diabetes, for example, severe hyperglycemia (high blood sugar), nausea, vomiting, diarrhea, rapid weight loss, lactic acidosis (see "Risk of lactic acidosis" below) or ketoacidosis. Ketoacidosis is a condition in which ketone bodies accumulate in the blood, which can lead to diabetic precoma. Symptoms include stomach pain, rapid and deep breathing, drowsiness, or an unusual fruity odor on your breath
• if you have a severe infection or are dehydrated
• if you are scheduled to undergo a radiography that requires the injection of a contrast agent. You will need to stop taking this medication at the time of the radiography and for 2 or more days after, as instructed by your doctor, depending on your kidney function
• if you have recently had a heart attack or have severe circulatory problems, such as "shock" or difficulty breathing
• if you have liver problems (hepatic)
• if you drink excessive amounts of alcohol (either daily or occasionally)
• if you are breastfeeding

Do not take this medication if any of the above circumstances apply to you and consult your doctor about other ways to control your diabetes. If you are unsure, consult your doctor, pharmacist, or nurse before starting to take this medication.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Disimet.

Cases of pancreatitis have been reported in patients treated with sitagliptin/metformin (see section 4).

If you notice blisters on your skin, it may be a sign of a condition called bullous pemphigoid. Your doctor may ask you to stop taking sitagliptin/metformin.

Risk of lactic acidosis

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

If any of the above applies to you, consult your doctor for further instructions.

Stop taking this medication for a short period of time if you have a condition that may be associated with dehydration(significant loss of body fluids), such as intense vomiting, diarrhea, fever, exposure to heat, or if you drink less fluid than normal. Consult your doctor for further instructions.

Stop taking this medication and contact a doctor or the nearest hospital immediately if you experience any of the symptoms that produce lactic acidosis, as this condition can lead to coma.

The symptoms of lactic acidosis include:

• vomiting
• stomach pain (abdominal pain)
• muscle cramps
• general feeling of discomfort, with intense fatigue
• difficulty breathing
• reduced body temperature and heart rate

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

Consult your doctor or pharmacist before starting to take this medication:

• if you have or have had a pancreatic disease (such as pancreatitis)
• if you have or have had gallstones, alcohol addiction, or have high levels of triglycerides in your blood. These medical conditions may increase your risk of developing pancreatitis (see section 4)
• if you have type 1 diabetes. This disease is also known as 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 sulfonilurea or insulin, other diabetes medications, as you may experience low blood sugar (hypoglycemia). Your doctor may consider reducing the dose of the sulfonilurea or insulin you are taking

If you need to undergo major surgery, you should stop taking sitagliptin/metformina while the procedure is being performed and for a period of time after. Your doctor will decide when to interrupt treatment with sitagliptin/metformina and when to restart it.

If you are unsure whether you are affected by any of the above circumstances, consult your doctor or pharmacist before starting to take this medication.

During treatment with sitagliptin/metformina, your doctor will check your kidney function at least once a year or more frequently if you are an elderly person and/or if your kidney function is deteriorating.

Consult your doctor quickly to determine how to proceed if:

-You know you have a genetic disease that affects the mitochondria (the components that produce energy inside cells), such as MELAS syndrome (mitochondrial encephalomyopathy, myopathy, lactic acidosis, and stroke-like episodes) or maternal diabetes and hearing loss (MIDD).

-You experience any of the following symptoms after starting treatment with metformin: convulsions, cognitive decline, difficulty with motor movements, symptoms indicative of nerve damage (e.g., pain or numbness), migraine, and hearing loss.

Children and adolescents

Children and adolescents under 18 years old should not use this medication. It is not known if this medication is safe and effective when used in children and adolescents under 18 years old.

Other medications and Disimet

If you need to receive an injection of a contrast agent containing iodine, such as during a radiography or examination, you should stop taking this medication before the injection or at the time of the injection. Your doctor will decide when to interrupt treatment with sitagliptin/metformina and when to restart it.

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication. You may need more frequent blood glucose and kidney function tests, or your doctor may need to adjust the dose of sitagliptin/metformina. It is especially important to mention the following:

• medications (taken orally, inhaled, or injected) used to treat inflammatory diseases, such as asthma and arthritis (corticosteroids)
• medications that increase urine production (diuretics)
• medications used to treat pain and inflammation (NSAIDs and COX-2 inhibitors, such as ibuprofen and celecoxib)
• specific medications used to treat high blood pressure (ACE inhibitors and angiotensin II receptor antagonists)
• medications specifically used to treat asthma (beta-2 agonists)
• iodinated contrast agents or medications containing alcohol
• specific medications used to treat stomach problems, such as cimetidine
• ranolazine, a medication used to treat angina pectoris
• dolutegravir, a medication used to treat HIV infection
• vandetanib, a medication used to treat a specific type of thyroid cancer (medullary thyroid cancer)
• digoxin (to treat irregular heartbeat and other heart problems). You may need to have your digoxin blood level checked if you are taking sitagliptin/metformina.

Taking Disimet with alcohol

Avoid excessive alcohol consumption while taking this medication, as this may increase the risk of lactic acidosis (see section "Warnings and precautions").

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, consult your doctor or pharmacist before using this medication. Do not take this medication during pregnancy or while breastfeeding. See section 2, Do not take Disimet

Driving and operating machinery

The influence of this medication on your ability to drive and operate machinery is negligible or insignificant. However, cases of dizziness and somnolence have been reported during treatment with sitagliptin, which may affect your ability to drive and operate machinery.

Taking this medication with medications called sulfonilureas or insulin may cause hypoglycemia, which may affect your ability to drive and operate machinery or work without a secure support.

This medication contains less than 23 mg of sodium (1 mmol) per tablet; it is essentially "sodium-free".

Follow exactly the administration instructions for this medication as indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.

• Take a tablet:
• • twice a day by mouth
  • with food to reduce the likelihood of stomach discomfort

• Your doctor may need to increase the dose to control blood sugar levels.

• If you have reduced renal function, your doctor may prescribe a lower dose.

You must continue with the diet recommended by your doctor during treatment with this medication and be careful to distribute carbohydrate intake evenly throughout the day.

It is unlikely that treatment with this medication alone will cause an abnormal drop in blood sugar (hypoglycemia). A drop in blood sugar may occur when this medication is taken with a medication containing sulfonylurea or insulin, so it is likely that your doctor will consider reducing the dose of your sulfonylurea or insulin.

If you take more Disimet than you should

If you take more than the prescribed dose of this medication, contact your doctor immediately. Go to the hospital if you experience symptoms of lactic acidosis such as feeling cold or unwell, intense nausea or vomiting, stomach pain, unexplained weight loss, muscle cramps, or agitated breathing (see "Warnings and precautions").

In case of overdose or accidental ingestion, consult the Toxicological Information Service. Phone 91 562 04 20.

If you forget to take Disimet

If you forget to take a dose, take it as soon as you remember. If you do not remember until your next scheduled dose, skip the missed dose and continue with your regular treatment. Do not take a double dose of this medication.

If you interrupt treatment with Disimet

Continue taking this medication as directed by your doctor to help control your blood sugar levels. Do not stop taking this medication without first consulting your doctor. If you interrupt treatment with sitagliptin/metformin, your blood sugar levels may increase again.

If you have any other questions about using this medication, ask your doctor or pharmacist.
