1.What Efficib is and what it is used for

Efficib contains two different medicines called sitagliptin and metformin.

sitagliptin belongs to a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors)

metformin belongs to a class of medicines called biguanides.

They work together to control blood sugar levels in adult patients with a form of diabetes called ‘type 2 diabetes mellitus’. This medicine helps to increase the levels of insulin produced after a meal and lowers the amount of sugar made by your body.

Along with diet and exercise, this medicine helps lower your blood sugar. This medicine can be used alone or with certain other medicines for diabetes (insulin, sulphonylureas, or glitazones).

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 Efficib

Do not take Efficib:

-if you are allergic to sitagliptin or metformin or any of the other ingredients of this medicine (listed in section 6)

-if you have severely reduced kidney function

-if you have uncontrolled diabetes, with e.g. severe hyperglycaemia (high blood glucose), nausea, vomiting, diarrhoea, rapid weight loss, lactic acidosis (see “Risk of lactic acidosis” below) or ketoacidosis. Ketoacidosis is a condition in which substances called ‘ketone bodies’ accumulate in the blood and which can lead to diabetic pre-coma. Symptoms include stomach pain, fast and deep breathing, sleepiness or your breath developing an unusual fruity smell.

-if you have a severe infection or are dehydrated

-if you are going to have an X-ray where you will be injected with a dye. You will need to stop taking Efficib at the time of the X-ray and for 2 or more days after as directed by your doctor, depending on how your kidneys are working

-if you have recently had a heart attack or have severe circulatory problems, such as ‘shock’ or breathing difficulties

-if you have liver problems

-if you drink alcohol to excess (either every day or only from time to time)

-if you are breast-feeding

Do not take Efficib if any of the above apply to you and talk with your doctor about other ways of managing your diabetes. If you are not sure, talk to your doctor, pharmacist or nurse before taking Efficib.

Warnings and precautions

Cases of inflammation of the pancreas (pancreatitis) have been reported in patients receiving Efficib (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 Efficib.

Risk of lactic acidosis

Efficib 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 Efficib 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 Efficib 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 Efficib:

-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 Efficib (see section 4)

-if you are taking a sulphonylurea or insulin, diabetes medicines, together with Efficib, 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 Efficib during and for some time after the procedure. Your doctor will decide when you must stop and when to restart your treatment with Efficib.

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

During treatment with Efficib, your doctor will check your kidney function at least once a year or more frequently if you are elderly and/or if you have worsening kidney function.

Children and adolescents

Children and adolescents below 18 years should not use this medicine. It is not known if this medicine is safe and effective when used in children and adolescents under 18 years of age.

Other medicines and Efficib

If you need to have an injection of a contrast medium that contains iodine into your bloodstream, for example, in the context of an X-ray or scan, you must stop taking Efficib before or at the time of the injection. Your doctor will decide when you must stop and when to restart your treatment with Efficib.

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 Efficib. 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)

medicines used to treat pain and inflammation (NSAID and COX-2-inhibitors, such as ibuprofen and celecoxib)

certain medicines for the treatment of high blood pressure (ACE inhibitors and angiotensin II receptor antagonists)

specific medicines for the treatment of bronchial asthma (β-sympathomimetics)

iodinated contrast agents or alcohol-containing medicines

certain medicines used to treat stomach problems such as cimetidine

digoxin (to treat irregular heart beat and other heart problems). The level of digoxin in your blood may need to be checked if taking with Efficib.

Efficib with alcohol

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

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 or if you are breast-feeding. See section 2, Do not take Efficib.

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 with sitagliptin, 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.

3.How to take Efficib

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Take one tablet:

twice daily by mouth

with meals to lower your chance of an upset stomach.

Your doctor may need to increase your dose to control your blood sugar.

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

You should continue the diet recommended by your doctor during treatment with this medicine and take care that your carbohydrate intake is equally distributed over the day.

This medicine alone is unlikely to cause abnormally low blood sugar (hypoglycaemia). When this medicine is used with a sulphonylurea medicine or with insulin, low blood sugar can occur and your doctor may reduce the dose of your sulphonylurea or insulin.

If you take more Efficib than you should

If you take more than the prescribed dosage of this medicine, contact your doctor immediately. Go to the hospital if you have symptoms of lactic acidosis such as feeling cold or uncomfortable, severe nausea or vomiting, stomach ache, unexplained weight loss, muscular cramps, or rapid breathing (see section “Warnings and precautions”).

If you forget to take Efficib

If you miss a dose, take it as soon as you remember. If you do not remember until it is time for your next dose, skip the missed dose and go back to your regular schedule. Do not take a double dose of this medicine.

If you stop taking Efficib

Continue to take this medicine as long as your doctor prescribes it so you can continue to help control your blood sugar. You should not stop taking this medicine without talking to your doctor first. If you stop taking Efficib, your blood sugar may rise again.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4.Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

STOP taking Efficib and contact a doctor immediately if you notice any of the following serious side effects:

Severe and persistent pain in the abdomen (stomach area) which might reach through to your back with or without nausea and vomiting, as these could be signs of an inflamed pancreas (pancreatitis).

Efficib may cause a very rare (may affect up to 1 in 10,000 people), but very serious side effect called lactic acidosis (see section “Warnings and precautions”). If this happens you must stop taking Efficib and contact a doctor or the nearest hospital immediately, as lactic acidosis may lead to coma.

If you have a serious allergic reaction (frequency not known), including rash, hives, blisters on the skin/peeling skin and swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing, stop taking this medicine and call your doctor right away. Your doctor may prescribe a medicine to treat your allergic reaction and a different medicine for your diabetes.
