What Metformin Almus Pharma is
Metformin Almus Pharma contains metformin, a medicine used to treat diabetes. It belongs to a group of medicines called biguanides.
Insulin is a hormone produced by the pancreas that makes your body take in glucose (sugar) from the blood. Your body uses glucose to produce energy or stores it for future use.
If you have diabetes, your pancreas does not produce enough insulin or your body cannot use the insulin it produces properly. This causes high blood glucose levels. Metformin helps reduce your blood glucose to as normal a level as possible.
If you are an adult with overweight, taking metformin for a long time also helps reduce the risk of complications associated with diabetes. Metformin Almus Pharma is associated with maintaining body weight or a slight decrease in body weight.
Metformin Almus Pharma is used to treat patients with type 2 diabetes (also called "non-insulin-dependent diabetes") when diet and exercise alone are not enough to control their blood glucose levels. It is especially used in patients with overweight.
Adults can take metformin alone or with other medicines to treat diabetes (oral medicines or insulin).
Children from 10 years old and adolescents can take metformin alone or with insulin.
Do not take Metformin Almus Pharma:
If any of the above circumstances apply to you, consult your doctor before starting to take this medicine.
Make sure to consult your doctor if:
You should stop taking metformin for a certain period before and after the examination or surgery. Your doctor will decide if you need any other treatment during this time. It is essential that you follow your doctor's instructions precisely.
Warnings and precautions
Consult your doctor or pharmacist before starting to take this medicine.
Risk of lactic acidosis
This medicine can cause a very rare but very serious side effect called lactic acidosis, especially if your kidneys do not work properly. The risk of developing lactic acidosis is also increased with uncontrolled diabetes, severe infections, prolonged fasting or alcohol consumption, dehydration (see more information below), liver problems, and any medical disorder in which a part of the body has a reduced oxygen supply (such as acute and severe heart diseases).
If any of the above applies to you, consult your doctor for further instructions.
Consult your doctor immediately to indicate how to proceed if:
Stop taking metformin for a short period if you have a disorder that may be associated with dehydration(significant loss of body fluids), such as severe vomiting, diarrhea, fever, heat exposure, or if you drink less fluid than usual. Consult your doctor for further instructions.
Stop taking metformin and contact a doctor or the nearest hospital immediately if you experience any of the symptoms that produce lactic acidosis, as this disorder can lead to a coma.
The symptoms of lactic acidosis include:
Lactic acidosis is a medical emergency and should be treated in a hospital.
If you need to undergo major surgery, you should stop taking metformin during the procedure and for a period after it. Your doctor will decide when you should stop taking metformin and when you can restart it.
Metformin alone does not cause hypoglycemia (a concentration of glucose in the blood that is too low). However, if you take metformin 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, increased heart rate, vision disorders, or difficulty concentrating, it is usually helpful to eat or drink something that contains sugar.
During treatment with metformin, your doctor will check your kidney function at least once a year or more frequently if you are an elderly person and/or if your kidney function is worsening.
Using Metformina Almus Pharma with other medicines
If you need to be given an injection of a contrast medium that contains iodine into your bloodstream, for example, in the context of an X-ray or examination, you should stop taking metformin before the injection or at the time of the injection. Your doctor will decide when you should stop taking metformin and when you can restart it.
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 dose of metformin.
It is especially important to mention the following:
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicine.
Taking Metformina Almus Pharma with alcohol
Avoid excessive alcohol consumption while taking metformin, as this can increase the risk of lactic acidosis (see section "Warnings and precautions").
Pregnancy and breastfeeding
During pregnancy, you need insulin to treat the diabetes you have. Tell your doctor if you are pregnant, think you may be pregnant, or plan to become pregnant, so that your treatment can be changed.
This medicine is not recommended if you are breastfeeding or plan to breastfeed your baby.
Driving and using machines
Treatment with metformin alone does not cause low blood sugar (hypoglycemia) and therefore does not affect your ability to drive or use machines.
However, be careful if you take metformin with other diabetes medicines that can cause hypoglycemia (such as sulfonylureas, insulin, meglitinides). The symptoms of hypoglycemia include weakness, dizziness, increased sweating, increased heart rate, vision disorders, or difficulty concentrating. Do not drive or use machines if you start to feel these symptoms.
Follow exactly the administration instructions of this medicine indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.
Metformin cannot replace the benefits of a healthy lifestyle. Continue to follow any dietary advice your doctor has given you and exercise regularly.
Recommended dose
Children from 10 years old and adolescents usually start with 500 mg or 850 mg of metformin once a day. The maximum daily dose is 2000 mg divided into 2 or 3 doses. Treatment of children between 10 and 12 years is only recommended under specific advice from your doctor, as clinical experience in this patient group is limited.
Adults usually start with 500 mg or 850 mg of metformin, two or three times a day. The maximum daily dose is 3000 mg divided into 3 doses.
If you have reduced kidney function, your doctor may prescribe a lower dose.
If you are also given insulin, your doctor will tell you how to start taking metformin.

If you take more Metformina Almus Pharma than you should
If you have taken more metformin than you should, you may suffer from lactic acidosis. The symptoms of lactic acidosis are non-specific, such as vomiting, stomach pain (abdominal pain) with cramps, a general feeling of discomfort with intense fatigue, and difficulty breathing. Additional symptoms may include a decrease in body temperature and heart rate. If you experience any of these symptoms, seek medical attention immediately, as lactic acidosis can lead to a coma.
