METFORMIN UXA 850 mg FILM-COATED TABLETS

2. What you need to know before you take Metformin Uxa

Do not take Metformin Uxa

• If you are allergic (hypersensitive) to metformin or any of the other ingredients of this medicine (listed in section 6).
• If you have liver problems
• If you have a severe reduction in kidney function;
• If you have uncontrolled diabetes with, for example, severe hyperglycemia (high blood sugar), nausea, vomiting, diarrhea, rapid weight loss, lactic acidosis (see "Risk of lactic acidosis" below) or ketoacidosis. Ketoacidosis is a disorder in which substances called "ketone bodies" accumulate in the blood, which can lead to a pre-diabetic coma. Symptoms include stomach pain, rapid and deep breathing, drowsiness or an unusual fruity odor in your breath.
• If you have lost a lot of water from your body (dehydration), for example due to prolonged or severe diarrhea or if you have vomited several times in a row. Dehydration can trigger kidney problems, which can put you at risk of developing lactic acidosis (see "Warnings and precautions").
• If you have a severe infection, for example an infection that affects your lungs, bronchi or kidneys. Severe infections can trigger kidney problems, which can put you at risk of developing lactic acidosis (see "Warnings and precautions").
• If you are receiving treatment for acute heart failure or if you have recently had a heart attack, if you have severe circulation problems (such as shock) or if you have difficulty breathing. This can lead to a lack of oxygenation in the tissues, which can put you at risk of developing lactic acidosis (see below "Warnings and precautions").
• If you drink a lot of alcohol.

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 need an examination such as an X-ray or a scan that involves injecting a contrast medium into your blood that contains iodine.
• you need major surgery.

You should stop taking Metformin Uxa for a certain period of time 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

Stop taking Metformin Uxa 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:

• vomiting
• stomach pain (abdominal pain)
• muscle cramps
• general feeling of discomfort, with intense fatigue
• difficulty breathing
• reduction in body temperature and heart rate

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 Uxa during the procedure and for a period after it. Your doctor will decide when you should stop taking Metformin Uxa and when you can restart it.

Metformin Uxa alone does not cause hypoglycemia (a blood glucose concentration that is too low). However, if you take Metformin Uxa 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 disturbances, or difficulty concentrating, it is usually helpful to eat or drink something that contains sugar.

During treatment with Metformin Uxa, your doctor will check your kidney function regularly and adjust your Metformin Uxa dose according to your blood glucose levels. Make sure to talk to your doctor regularly. This is especially important for children, adolescents, or if you are an elderly person.

Other medicines and Metformin Uxa

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 scan, you should stop taking Metformin Uxa before the injection or at the time of the injection. Your doctor will decide when you should stop taking Metformin Uxa 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 Uxa. It is especially important to mention the following:

• medicines that increase urine production (diuretics)
• medicines used to treat pain and inflammation (NSAIDs and COX-2 inhibitors, such as ibuprofen and celecoxib)
• certain medicines to treat 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 various conditions, such as severe skin inflammation or asthma)
• medicines that may alter the amount of Metformin Uxa in your blood, especially if you have reduced kidney function (such as verapamil, rifampicin, cimetidine, dolutegravir, ranolazine, trimethoprim, vandetanib, isavuconazole, crizotinib, olaparib).
• other medicines used to treat diabetes.

Taking Metformin Uxa with alcohol

Avoid excessive alcohol consumption while taking Metformin Uxa, 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.

It is not recommended to take this medicine if you are breastfeeding or plan to breastfeed your baby.

Driving and using machines

Metformin Uxa alone does not cause hypoglycemia (a blood glucose concentration that is too low). This means it will not affect your ability to drive or use machines.

However, be especially careful if you take Metformin Uxa 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 disturbances, or difficulty concentrating. Do not drive or use machines if you start to feel these symptoms.
