1.
What Metformin Actavis is and what it is used for
Metformin Actavis is used in diabetes mellitus in adults, especially in overweight patients, when diet and
exercise have not reduced sugar levels.
Metformin Actavis lowers the blood sugar in diabetes without causing the levels to drop too low. Metformin
Actavis can be used as single treatment or in combination with other oral medications (sulfonylureas) or
together with insulin, to reduce the blood sugar .
2.

Do not take Metformin Actavis
if you are allergic to metformin or any of the other ingredients of this medicine (listed in section 6).
if you have liver problems or drink a lot of alcohol
if you have kidney problems
if you have severe heart or pulmonary disease
if you have a tendency for developing diabetic ketoacidosis and diabetic pre-coma
if you have a severe infection
if you are seriously dehydrated (lost a lot of water from your body, which can happen if you have
severe sickness or diarrhoea)
in the condition of shock
Warnings and precautions
Please note the following particular risk of lactic acidosis.
Metformin Actavis may cause a very rare, but very serious complication called lactic acidosis, particularly if
your kidneys are not working properly. The risk of developing lactic acidosis is also increased with
uncontrolled diabetes, prolonged fasting or alcohol intake, body fluid deficit (dehydration) due to severe
diarrhoea or vomiting, liver problems and any medical conditions in which a region of the body is deprived
with a lack of oxygen supply (such as acute severe heart diseases).
It is important to you to comply with your medication intake, dietary instructions and regular exercise
program because this can reduce the risk of lactic acidosis.
1
The onset of lactic acidosis can be subtle and the symptoms can be non-specific such as vomiting, bellyache
(abdominal pain) 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 seek immediately medical attention, as lactic acidosis may lead to
coma. Stop taking Metformin Actavis immediately and contact a doctor or the nearest hospital
straight away.
Talk to your doctor or pharmacist before taking Metformin Actavis
- If you have diabetes developed during old age and your kidney function is reduced
If you are going to undergo an x-ray procedure where a contrast agent is used containing iodine, the
treatment with Metformin Actavis must be stopped before or at the start of the procedure. Medication may
not be restarted again until 48 hours after the procedure and only after the kidney function has been tested
again and found to be normal.
In connection with surgery, a doctor should be consulted and the medication must be stopped.
When Metformin Actavis is taken together with other antidiabetic medications such as insulin or other
antidiabetics such as sulphonureas or meglitinides, the possibility of low blood sugar (hypoglycaemia) can
occur. Symptoms of low blood sugar such as sweating, shakiness, anxiety, palpitation of the heart and
hunger might appear. In such cases it is often helpful to drink milk or take sugar or something similar.
Patients should continue their diet with a regular distribution of carbohydrates during the day. Patients who
are overweight should continue on their low energy diet.
Usual laboratory tests for monitoring diabetes should be done on a regular basis.

malnutriation. Therefore it is recommended to avoid alcohol during treatment with Metformin Actavis.

Breast-feeding
Metformin Actavis passes on to human breast milk. Breast-feeding during metformin treatment is not
