Yaltormin SR prolonged release tablets contain the active ingredient metformin hydrochloride and belong to a group of medicines called biguanides, used in the treatment of diabetes. Yaltormin SR is used for the treatment of Type 2 (non-insulin dependent) diabetes mellitus when diet and exercise changes alone have not been enough to control blood glucose (sugar). Insulin is a hormone that enables body tissues to take glucose from the blood and to use it for energy or for storage for future use. People with Type 2 diabetes do not make enough insulin in their pancreas or their body does not respond properly to the insulin it does make. This causes a build-up of glucose in the blood which can cause a number of serious long-term problems so it is important that you continue to take your medicine, even though you may not have any obvious symptoms. Yaltormin SR makes the body more sensitive to insulin and helps return to normal the way your body uses glucose.
Yaltormin SR is associated with either a stable body weight or modest weight loss.
Yaltormin SR Prolonged Release Tablets are specially made to release the drug slowly in your body and therefore are different to many other types of tablet containing metformin.
Risk of lactic acidosis
Yaltormin SR 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 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 Yaltormin SR 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 Yaltormin SR 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:
Lactic acidosis is a medical emergency and must be treated in a hospital.
If you need to have major surgery you must stop taking Yaltormin SR during and for some time after the procedure. Your doctor will decide when you must stop and when to restart your treatment with Yaltormin SR.
During treatment with Yaltormin SR, 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.
If you are older than 75 years, treatment with Yaltormin SR should not be started to lower the risk of developing type 2 diabetes
You may see some remains of the tablets in your stools. Do not worry- this is normal for this type of tablet.
You should continue to follow any dietary advice that your doctor has given you and you should make sure that you eat carbohydrates regularly throughout the day.
Do not stop taking this medicine without speaking to your doctor.
If you need to have an injection of contrast medium that contains iodine into your bloodstream, in the context of an X-ray or scan, you must stop taking Yaltormin SR before or at the time of the injection. Your doctor will decide when you must stop and when to restart your treatment with Yaltormin SR.
Tell your doctor 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 Yaltormin SR. It is especially important to mention the following:
Avoid excessive alcohol intake while taking Yaltormin SR since this may increase the risk of lactic acidosis (see section ‘Warnings and precautions’).
Do not take Yaltormin SR if you are pregnant or breast feeding. Ask your doctor or pharmacist for advice before taking any medicine.
Yaltormin SR taken on its own does not cause ‘hypos’ (symptoms of low blood sugar or hypoglycaemia, such as faintness, confusion and increased sweating) and therefore should not affect your ability to drive or use machinery.
You should be aware, however, that Yaltormin SR taken with other antidiabetic medicines can cause hypos, so in this case you should take extra care when driving or operating machinery.
This medicine contains less than 1mmol sodium (23mg) per dosage unit, that is to say it is essentially ‘sodium free’.
Your doctor may prescribe Yaltormin SR for you to take on its own, or in combination with other oral antidiabetic medicines or insulin.
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Swallow the tablets whole with a glass of water; do not chew.
Recommended dose
Usually you will start treatment with 500 milligrams Yaltormin SR daily. After you have been taking Yaltormin SR for about 2 weeks, your doctor may measure your blood sugar and adjust the dose. The maximum daily dose is 2000 milligrams of Yaltormin SR.
In renal impaired patients with a GFR between 45 and 60 ml/min, the starting dose is 500 mg or 750 mg Yaltormin SR once daily. The maximum dose is 1000 mg daily. The renal function should be closely monitored (every 3 – 6 months).
Normally, you should take the tablets once a day, with your evening meal.
In some cases, your doctor may recommend that you take the tablets twice a day. Always take the tablets with food.
If you have reduced kidney function, your doctor may prescribe a lower dose.
If you take extra tablets by mistake you need not worry, but if you have unusual symptoms, contact your doctor. If the overdose is large, lactic acidosis is more likely. Symptoms of lactic acidosis are non-specific, such as vomiting, bellyache with muscle cramps, a general feeling of not being well with severe tiredness, and difficulty in breathing. Further symptoms are reduced body temperature and heart beat. If you experience some of these symptoms, you should immediately seek medical attention, as lactic acidosis may lead to coma. Stop taking Yaltormin SR immediately and contact a doctor or the nearest hospital straightaway.
Take it as soon as you remember with some food. Do not take a double dose to make up for a forgotten dose.
