1. What Metformin Oral Solution is and what it is used for

■    Metformin Colonis 850mg/5ml Oral Solution (referred to as Metformin Oral Solution in this leaflet) contains metformin hydrochloride, a medicine to treat diabetes. It belongs to a group of medicines called biguanides.

■    After you have eaten, your body converts the carbohydrates and sugar in your food into glucose, which travels in your blood to where it is needed. Insulin is a hormone produced in your pancreas which moves the glucose from your blood into your body’s cells where it is used as energy (fuel)

■    If you have type 2 diabetes, your pancreas does not make enough insulin or your body is not able to use properly the insulin it produces, (known as insulin resistance). This leads to

high levels of glucose in your blood. Metformin Oral Solution helps to lower your blood glucose to as normal a level as possible.

■    This medicine is used to treat patients with type 2 diabetes (also called ‘noninsulin dependent diabetes’) when diet and exercise alone have not been enough to control your blood glucose levels. It is often used in overweight patients.

■    If you are an overweight adult, taking this medicine over a long period of time can also help lower the risk

of complications associated with diabetes. This medicine is associated with either a stable body weight or modest weight loss.

   Adults can take this medicine on its own or together with other medicines to treat diabetes or with insulin.

   Adolescents and children aged 10 years and over can take this medicine on its own or together with insulin.

2. What you need to know before you take Metformin Oral Solution

Do not take Metformin Oral Solution

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

■    if you have uncontrolled diabetes, with e.g. severe hyperglycaemia (high levels of blood glucose in your blood), nausea (feeling sick), vomiting (being sick), dehydration or rapid weight loss

■    if you have symptoms of a condition called ketoacidosis in which substances called ‘ketone bodies’ accumulate in the blood and can lead to diabetic pre-coma (unconsciousness). Symptoms include stomach pain, fast and deep breathing, sleepiness and unusual fruity odour of the breath (likened to the smell of pear drops)

■    if you have moderate or severe liver or kidney problems

■    if you become dehydrated (when ou lose too much water from your ody), due to long-lasting or severe

diarrhoea, or if you have been sick several times in a short space of time. Dehydration may lead to kidney problems, which can put you at risk of lactic acidosis (see ‘Warnings and precautions’)

■    if you have a severe infection,

such as an infection affecting your lungs, airways or your kidneys.

Severe infections may lead to kidney problems, which can put you at risk of lactic acidosis (see ‘Warnings and precautions’ and Section 4 Possible side effects)

■    if you are treated for acute heart failure or have recently had a heart attack, have severe problems with

our circulation (such as shock) or ave breathing difficulties. This may lead to a lack of oxygen in your body tissues which can put you at risk of lactic acidosis (see “Warnings and precautions”)

■    if you drink a lot of alcohol

If any of the above applies to you, talk to

your doctor, before you start taking this

medicine.

Warnings and precautions

■    Metformin Oral Solution may cause a very rare, but very serious complication called lactic acidosis, particularly if your kidneys are not working properly

(kidney function may worsen when starting medication for high blood pressure, water retention and when starting treatment with Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).

■    The risk of developing lactic acidosis is also increased with:

■    uncontrolled diabetes

■    prolonged fasting or alcohol intake loss ofbody fluid (dehydration) due to severe diarrhoea or vomiting (being sick)

■    liver problems

■    any medical conditions in which a region of the body is deprived of oxygen (such as acute severe heart diseases).

■    It is important you take your medication as prescribed, follow dietary instructions and keep up your regular exercise program because these measures can reduce the risk of lactic acidosis.

■    The onset of lactic acidosis can be

subtle and the symptoms can be nonspecific such as:

■    being sick (vomiting)

■    stomach ache (abdominal pain) with muscle cramps

■    a general feeling of not being well with severe tiredness

■    difficulty in breathing

■    further symptoms are reduced body temperature and heartbeat.

If you experience some of these symptoms, stop taking this medicine and seek medical attention immediately.

■    Talk to your doctor or pharmacist before using Metformin Oral Solution if:

■    you need to have a diagnostic examination such as X-ray or scan involving the injection of contrast dyes that contain iodine into your bloodstream

■    you need to have surgery in which you will be given an anaesthetic (put to sleep).

You must stop taking Metformin Oral Solution for a certain period of time before and after the examination or surgery. Your doctor will tell you what you need to do and will decide whether you need any other treatments during this time. It is important that you follow your doctor’s instructions precisely.

■    On its own this medicine does not cause hypoglycaemia (a condition when your blood glucose levels become too low). However, if you take Metformin Oral Solution together with other medicines used to treat diabetes (such as sulphonylureas, insulin, meglitinides), there is a risk of hypoglycaemia. If you experience symptoms such as weakness, dizziness, increased sweating, fast heart beating, vision disorders or difficulty in concentration, it usually helps to eat or drink something containing sugar.

Children aged 10 and over and adolescents

■    This medicine may be used in children aged 10 and over either by itself or in combination with insulin.

   Regular monitoring of children taking this medicine is recommended

Other medicines and Metformin Oral Solution

■    If you need to have an injection of a contrast dye medicine that contains iodine for a diagnostic examination such as an X-ray or scan, you will need to stop taking Metformin Oral Solution for a period of time both before and after the examination (at least 48 hours). It is important that you discuss this with your doctor beforehand.

■    Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including those bought without a prescription.

■    You may need more frequent blood glucose tests or your doctor may adjust the dosage of Metformin Oral Solution if you are taking or have recently taken:

■    diuretics (used to remove water from the body by making more urine).

■    beta-2 agonists such as salbutamol or terbutaline (used to treat asthma)

■    corticosteroids such as prednisolone (used to treat a variety of conditions including asthma and inflammation)

■    other medicines used to treat diabetes

■    Non-Steroidal Anti-Inflammatories (NSAIDS) such as diclofenac (used to treat inflammation)

Metformin Oral Solution with food and drink

Do not drink alcohol when you take this medicine. Alcohol may increase the risk of lactic acidosis especially if you have liver problems or if you are undernourished. This also applies to medicines that contain alcohol.

Pregnancy and breast-feeding

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

■    During pregnancy, you need to use insulin to treat your diabetes rather than Metformin Oral Solution. Tell your doctor if you are pregnant, think you may be pregnant or are planning to have a baby, so that they can change your treatment.

■    This medicine is not recommended if you are breast-feeding or if you are planning to breast-feed your baby.

Driving and using machines

■    Taken on its own this medicine does not cause hypoglycaemia (a condition where your blood glucose levels become too low). This means that it will not affect your ability to drive or use machines.

■    If this medicine is taken with insulin or other medicines used to treat diabetes that can cause hypoglycaemia (such as sulphonylureas, insulin and meglitinides), it is possible that their combined effects may make you feel faint or dizzy. Other symptoms

of hypoglycaemia include weakness, increased sweating, fast heartbeat, vision disorders and difficulty concentrating. If you experience any of these symptoms do not drive or operate machinery until you feel better.
