Metformin hydrochloride
Ranmet XR contains the active substance metformin hydrochloride, which belongs to a group of medicines called biguanides and is used to treat diabetes.
Ranmet XR is used to treat type 2 diabetes (also known as non-insulin-dependent) in adults, where diet and exercise alone are not enough to control blood sugar levels. Insulin is a hormone that allows the body to take up glucose from the blood and use it for energy or store it for future use. In type 2 diabetes, the pancreas does not produce enough insulin or the body does not respond properly to the insulin produced. This leads to high blood sugar levels, which can cause a number of serious and long-term problems, so it is important to continue taking the medicine even if you do not have any obvious symptoms. Ranmet XR makes the body more sensitive to insulin and helps the body to use glucose properly.
Taking Ranmet XR is associated with either maintaining body weight or only a small increase in body weight.
If any of the above situations apply to you, you should consult your doctor before taking this medicine.
You should consult your doctor if:
Before starting to take Ranmet XR, you should discuss it with your doctor.
After starting to take the medicine:
If you have diabetes, you should regularly check your blood and urine for glucose.
During treatment with Ranmet XR, your doctor will check your kidney function at least once a year or more often if you are elderly and/or have impaired kidney function.
Ranmet XR may cause a very rare but very serious side effect called lactic acidosis, especially if you have kidney problems. The risk of lactic acidosis increases in cases of uncontrolled diabetes, severe infection, prolonged fasting or alcohol consumption, dehydration (see more information below), liver disease, and any conditions in which a part of the body is not getting enough oxygen (e.g. acute severe heart disease).
If any of the above situations apply to you, you should consult your doctor for more detailed instructions.

If you are going to have a major surgical procedure, you should not take Ranmet XR during the procedure and for a certain period after it. Your doctor will decide when you should stop and restart taking Ranmet XR.
Ranmet XR does not cause hypoglycemia (low blood sugar). However, if Ranmet XR is taken with other diabetes medicines that can cause hypoglycemia (such as sulfonylureas, insulin, meglitinides), there is a risk of hypoglycemia. If you experience symptoms of hypoglycemia, such as weakness, dizziness, increased sweating, rapid heartbeat, vision problems, or difficulty concentrating, eating food or drinking a sugary drink usually helps.
You may find remains of the tablets in your stool. Do not worry, as this is normal with this type of tablet.
You should continue to follow your doctor's advice about diet and make sure you eat carbohydrates regularly throughout the day.
You should not stop taking this medicine without consulting your doctor.
This medicine should not be used in children and adolescents. It is not known if this medicine is safe and effective when used in children and adolescents under 18 years of age.
If you are going to have an iodine-containing contrast agent injected into your bloodstream, for example for an X-ray or CT scan, you should stop taking Ranmet XR before or at the latest at the time of the injection. Your doctor will decide when you should stop and restart taking Ranmet XR.
You should tell your doctor or pharmacist about all the medicines you are taking or have recently taken, as well as any medicines you plan to take. You may need more frequent blood sugar checks and kidney function tests, or your doctor may need to adjust your dose of Ranmet XR. It is especially important to tell your doctor about the following medicines, such as:
Ranmet XR should be taken with a meal or immediately after a meal, for example with dinner.
You should avoid drinking excessive amounts of alcohol while taking Ranmet XR,
as this may increase the risk of lactic acidosis (see "Warnings and precautions").
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, you should ask your doctor or pharmacist for advice before taking this medicine. You should not take Ranmet XR if you are pregnant.
Ranmet XR is not recommended if you are breastfeeding or planning to breastfeed.
Ranmet XR itself does not cause hypoglycemia (symptoms of low blood sugar, such as fainting, disorientation, and increased sweating) and therefore does not affect your ability to drive or use machines.
However, you should be careful when driving or using machines if you are taking Ranmet XR with other diabetes medicines that can cause low blood sugar.
Your doctor may recommend taking Ranmet XR alone or in combination with other oral diabetes medicines or insulin.

Treatment usually starts with a dose of 500 mg of Ranmet XR once a day.
After about two weeks of taking the medicine, your doctor may adjust the dose based on your blood sugar measurements. The maximum dose of Ranmet XR is 2000 mg per day. If you have kidney problems, your doctor may prescribe a lower dose.
If you are also taking insulin, your doctor will tell you how to start taking Ranmet XR.
Usually, you should take the tablets once a day with your evening meal.
In some cases, your doctor may recommend taking the tablets twice a day. You should always take the tablets with a meal.
Swallow the tablets whole with a glass of water, do not chew, break, or crush the tablets.
If after some time you feel that the effect of Ranmet XR is too strong or too weak, you should consult your doctor or pharmacist.

The dose should be determined after assessing kidney function.
If you accidentally take extra tablets, you should not worry, but if you experience unusual symptoms, you should contact your doctor. Symptoms may include weakness, disorientation, rapid breathing, and nausea, vomiting, or abdominal pain.
If the overdose is significant, the risk of lactic acidosis is higher. This is a life-threatening condition that requires immediate treatment in a hospital (see also section 4 "Possible side effects").
As soon as you remember, you should take the missed dose with any meal.
You should not take a double dose to make up for a missed dose.
You should not stop taking this medicine without consulting your doctor. If you stop taking Ranmet XR, your blood sugar levels may increase again.
