What Metformin EQL is and what it is used for
Metformin EQL contains metformin, a medicine used to treat diabetes. It belongs to a group of drugs called biguanides.
Insulin is a hormone produced in the pancreas that helps the body absorb glucose (sugar) from the blood. The body uses glucose to produce energy or stores it for future needs. If you have diabetes, the pancreas does not produce enough insulin or the body cannot use the insulin that is produced well enough. This leads to high glucose levels in the blood. Metformin EQL helps to lower blood glucose levels to a level that is as close to normal as possible.
If you are an adult and overweight, taking Metformin EQL for a long time can also help reduce the risk of complications associated with diabetes. Metformin EQL is associated with either stable body weight or a slight weight loss.
Metformin EQL is used to treat patients with type 2 diabetes (also known as “non-insulin-dependent diabetes”) when diet and exercise alone are not sufficient to control blood glucose levels, especially for obese patients.
Adults can take Metformin EQL as the only treatment or together with other medicines to treat diabetes (medicines taken by mouth or insulin ).
Children 10 years of age or older and adolescents can take Metformin EQL as their only treatment or with insulin.
Metformin EQL may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist or another healthcare professional if you have any further questions and always follow their instructions.
What you need to know before using Metformin EQL
Do not use Metformin EQL
- if you are allergic (hypersensitive) to metformin or to any of the other ingredients of this medicine (see section 6, ‘Contents of contents’).
- if you have liver problems
- if you have severe renal impairment
- if you have uncontrolled diabetes with, for example, severe hyperglycaemia (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 substances called ketone bodies accumulate in the blood, which can lead to diabetic precoma. Symptoms include stomach pain, rapid and deep breathing, drowsiness or that your breath has a different, fruity odor.
- if the body has lost too much water (dehydration), e.g. due to prolonged or severe diarrhea, or if you have vomited several times in a row. Dehydration can lead to kidney problems which can cause lactic acidosis (See “Warnings and Precautions”).
- if you have a severe infection , e.g. an infection that affects the lungs, trachea or kidneys. Severe infections can lead to kidney problems which can cause lactic acidosis (See “Warnings and Precautions”).
- if you are being treated for acute heart failure or have recently had a heart attack, if you have severe circulatory problems (such as shock ) or difficulty breathing. This can lead to a lack of oxygen in tissue one, which can cause lactic acidosis (see “Warnings and Precautions”).
- if you drink a lot of alcohol
If any of these apply to you, do not take this medicine but talk to a doctor.
You need to consult a doctor about
- you need to have an examination, such as an X-ray or a computed tomography scan , which means that you are receiving contrast media containing iodine injected into your blood
- you will undergo major surgery
You must stop taking Metformin EQL for some time before and after the examination or operation. Your doctor will decide if you need any other treatment during this time. You must follow your doctor’s instructions carefully.
Warnings and cautions
Risk of lactic acidosis
Metformin EQL can cause the very rare, but very serious, side effect of lactic acidosis, especially if your kidneys are not working properly. The risk of developing lactic acidosis is also increased in uncontrolled diabetes, severe infections, prolonged fasting or alcohol intake, dehydration (see more information below), liver problems and conditions where part of the body has reduced oxygen supply (including acute severe heart disease).
If any of the above apply to you, talk to your doctor for further information.
Stop taking Metformin EQL for a short time if you have a condition that may be associated with dehydration, such as severe vomiting, diarrhoea, fever, exposure to heat or if you drink less fluid than normal. Talk to a doctor for further instructions.
Stop taking Metformin EQL and contact a doctor or nearest hospital immediately if you experience any of the symptoms of lactic acidosis as the condition may lead to coma.
The symptoms of lactic acidosis include:
- abdominal pain (stomach pain)
- muscle cramps
- a general feeling of not feeling well and pronounced fatigue
- hard to breathe
- lowered body temperature and heart rate
Lactic acidosis is an acute medical condition that must be treated in a hospital.
If you are going to undergo a major operation, you must stop taking Metformin EQL during the operation and for a certain time after it. Your doctor will decide when you need to stop taking Metformin EQL and when you should start taking it again.
Metformin EQL itself does not cause hypoglycaemia (too low blood sugar) but if you take Metformin EQL with other antidiabetic medicines that can cause hypoglycaemia (eg sulphonylureas, insulin, meglitinides) there is a risk of hypoglycaemia. If you experience symptoms of hypoglycaemia, such as weakness, dizziness, sweating, rapid heartbeat, visual disturbances or difficulty concentrating, eating or drinking something containing sugar usually helps.
During treatment with Metformin EQL, your doctor will check your kidney function at least once a year or more often if you are older and/or if your kidney function is deteriorating.
Other drugs and Metformin EQL
If you need to get an injection into your blood with a contrast agent that contains iodine, for example in connection with X-rays or computed tomography, you must stop taking Metformin EQL before or at the time of injection. Your doctor will decide when you need to stop taking Metformin EQL and when you should start taking it again.
Tell your doctor if you are taking, have recently taken or might take any other medicines. You may need to do more blood sugar and kidney function tests, or your doctor may need to adjust the dose of Metformin EQL. You must mention the following;
- drugs that increase urine production ( diuretics ).
- drugs used to treat pain and inflammation ( NSAIDs 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).
- beta-2 agonists such as salbutamol or terbutaline (used to treat asthma ).
- corticosteroids (used to treat a variety of conditions, such as severe dermatitis or asthma ).
- medicines that can change the amount of Metformin EQL in your blood, especially if you have impaired kidney function (eg verapamil, rifampicin, cimetidine, dolutegravir, ranolazine, trimethoprim, vandetanib, isavuconazole, crizotinib, olaparib).
- other drugs used to treat diabetes
Metformin EQL with food, drink and alcohol
Avoid high alcohol intake while taking Metformin EQL as alcohol may increase the risk of lactic acidosis (see section “Warnings and precautions”).
Pregnancy, breastfeeding and fertility
During pregnancy, you need insulin to treat your diabetes. Tell your doctor if you are or think you may be pregnant or are planning to have a baby so that he or she can change your treatment. This medicine is not recommended if you are breastfeeding or planning to breastfeed your baby.
Driving and using machines
Metformin EQL alone does not cause hypoglycaemia (too low a blood glucose level). This means that it does not affect your ability to drive or use machines.
However, you should be especially careful if you take Metformin EQL with other antidiabetic medicines that can cause hypoglycaemia (eg sulphonylureas, insulin, meglitinides). Symptoms of hypoglycaemia include weakness, dizziness, sweating, rapid heartbeat, visual disturbances or difficulty concentrating. Do not drive or use machines if you experience such symptoms.
You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened vigilance. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.
