What is AVANDAMET used for?
AVANDAMET is used to treat patients with type 2 diabetes mellitus. This is also called non-insulin dependent diabetes (NIDDM) or maturity onset diabetes.
Type 2 diabetes mellitus is a condition in which your body does not make enough insulin or where the insulin that your body produces does not work as well as it should. Insulin is a natural body chemical that helps the body’s cells use the sugar from the blood and so stops your blood sugar levels from rising too high. High blood sugar levels can cause damage to the body’s cells.
AVANDAMET contains two active ingredients; namely rosiglitazone (as maleate), which belongs to a group of medicines called glitazones, and metformin hydrochloride which belongs to a group of medicines called biguanides.
AVANDAMET acts by making your body more sensitive to insulin. It therefore helps your body make better use of the insulin it produces and thus helps to restore your blood sugar towards a normal level.
AVANDAMET can be used alone (when diet and exercise is not enough to treat your diabetes) or together with other anti-diabetic medicines.
Your doctor may have prescribed AVANDAMET for another reason.
There is no evidence that AVANDAMET is addictive.
Before you take AVANDAMET
Do not take if:
You must not take AVANDAMET if:
you have ever had an allergic reaction to rosiglitazone, metformin or any of the ingredients listed toward the end of this leaflet (See “Ingredients”). Signs of an allergic or ‘anaphylactic’ reaction may include itchy skin rash (hives), shortness of breath, difficulty breathing, wheezing swelling of the face, tongue or other parts of the body or fainting.
you have heart failure or have had heart failure in the past.
you are being treated for angina or having a heart attack.
you have juvenile diabetes mellitus that is uncomplicated and well regulated on insulin; diabetes mellitus which is regulated by diet alone; acute complications of diabetes mellitus such as metabolic acidosis, coma, infection, gangrene, or during or immediately following surgery where insulin is essential.
you have kidney failure or reduced kidney function (e.g. if you are elderly).
you have any conditions that may be associated with tissue hypoxia (where the tissue is deprived of oxygen) (e.g. gangrene, circulatory shock, acute significant blood loss); pulmonary embolism; severe liver failure; pancreatitis; excessive alcohol intake or the use of diuretics. This is due to the risk of lactic acidosis (an increased amount of lactic acid in the blood).
the expiry date (EXP) printed on the pack has passed.

you have polycystic ovary syndrome. Due to the way your medicine works there may be an increased risk of pregnancy.
you are allergic to foods, dyes, preservatives or any other medicines.
you are taking any other medicines, including medicines you buy without a prescription. In particular, medicines that can affect the amount of sugar in your blood if you take them with AVANDAMET such as gemfibrozil, rifampicin, cimetidine and medicines that may change the amount of metformin in your blood, (especially if you have reduced kidney function) such as verapamil, rifampicin, cimetidine, dolutegravir, ranolazine, trimethoprim, vandetanib, isavuconazole, crizotinib, olaparib.
you have kidney failure or may have reduced kidney function (e.g. if you are elderly).
Broken bones, usually in the hand, upper arm or foot, have been seen with rosiglitazone use. Talk to your doctor for advice on how to keep your bones healthy.
AVANDAMET only works in the presence of the body’s own insulin therefore it should not be used in patients with type 1 (or insulin dependent) diabetes mellitus.
There is no information available on the use of AVANDAMET in people under 18 years of age, therefore its use in these patients is not recommended.
How do I take AVANDAMET?
How much to take:
Take AVANDAMET as directed by your doctor or pharmacist.
The amount of AVANDAMET people take can be different, and this depends on your condition. Your doctor will prescribe the best dose for you.
Do not take more tablets than your doctor has recommended.
How to take it:
Your AVANDAMET tablets should be swallowed with a glass of water. They may be taken with or after a meal or on an empty stomach.
However, taking your tablets with or just after food will lessen the chance of a stomach upset.
It is best to take the tablets at the same time each day.
How long to take it for:
Diabetes is a condition that requires long term treatment and regular assessment by your doctor.Once you have started taking medication, you will normally need to keep taking it for the rest of your life.
If you feel the effect of your medicine is too weak or too strong do not stop taking AVANDAMET or change the dose yourself, but ask your doctor.
Your doctor may prescribe AVANDAMET in combination with other anti-diabetic medicines. Read the leaflets for these medicines too.
Use in children:
There is no information available on the use of AVANDAMET in people under 18 years of age, therefore its use in these patients is not recommended.
What do I do if I take too much?(Overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 131126) for advice, if you think you or anyone else may have taken too much AVANDAMET, even if there are no signs of discomfort or poisoning.
If you are not sure what to do, contact your doctor, pharmacist or nearest hospital.
While you are taking AVANDAMET
Things you must do:
Tell your doctor if, for any reason, you have not taken your medicine exactly as directed.
Otherwise, your doctor may think that it was not working as it should and change your treatment unnecessarily.
If you forget to take AVANDAMET, take your tablet as soon as you remember.Do not take any more than the usual dose.Take your next dose at the usual time.
When taking AVANDAMET do not take any additional medicine containing metformin, either as a single or combination dose. Seek advice from your doctor or pharmacist.

Do not use AVANDAMET to treat any other complaints unless your doctor says to.
Do not skip meals while taking AVANDAMET.
Do not stop taking AVANDAMET or change the dose without checking with your doctor first.
Things to be careful of:
Be careful driving or operating machinery until you know how AVANDAMET affects you.
If you have to be alert, for example when driving, be especially careful not to let your blood glucose levels fall too low.
Excessive alcohol intake should be avoided while taking AVANDAMET as it can enhance the effect of this medicine and can also cause lactic acidosis (an increased amount of lactic acid in the blood).
If you are elderly, you may have reduced kidney function and your doctor may wish to adjust your dose.
If you have any concerns you should speak to your doctor. Do not stop taking AVANDAMET or change the dose without checking with your doctor first.
What are the side-effects?
Check with your doctor as soon as possible if you think you are experiencing any side effects or allergic reactions due to taking AVANDAMET, even if the problem is not listed below.
AVANDAMET may increase the risk of heart attack or heart failure in some patients. You must tell your doctor immediately if you develop any of the following:
rapid increase in weight
shortness of breath
swelling of legs and feet
chest pain
Like other medicines, AVANDAMET can cause some side-effects. If they occur, they are most likely to be minor and temporary. However, some may be serious and need medical attention.
The most commonly reported side-effects are:
heart failure or fluid in the lungs (pulmonary oedema).
heart problems such as angina or heart attack.
localised swelling (oedema)
a small increase in weight.
low sugar levels in the blood (hypoglycaemia).
a small reduction in red blood cell count (anaemia) and white blood cell count.
broken bones, usually in the hand, upper arm or foot.
metallic taste in the mouth.
an increase in appetite.
constipation.
Tell your doctor immediately if you notice any of the following:
stomach upset such as nausea or vomiting.
diarrhoea.
chest pain.
itching, rash.
dark urine or pale stools.
yellowing of the skin or eyes (jaundice).
severe stomach cramps.
loss of weight.
tiredness.
shortness of breath.
swelling or pain of legs and feet.
rapid increase in weight.
visual disorders.
itchy skin rash (hives), shortness of breath, difficulty breathing, wheezing, swelling of the face, tongue or other parts of the body or fainting. These could be symptoms of an allergic reaction.
AVANDAMET may increase your total cholesterol level slightly. Total cholesterol is made up of ‘good cholesterol’ (HDLc) and ‘bad cholesterol’ (LDLc) and it is the balance of these that is more important than the total level. AVANDAMET does not affect the balance of good and bad cholesterol. If you have any concerns about your cholesterol levels you should speak to your doctor.
Tell your doctor immediately or go to the Emergency Department at the nearest hospital if you notice any of the following symptoms of lactic acidosis (high lactic acid in the blood):
nausea, vomiting or stomach pain.
difficulty in breathing.
feeling weak, tired or generally unwell.
unusual muscle pain.
sleepiness.
dizziness or light-headedness.
shivering, feeling extremely cold.
slow heart beat.
You may need urgent medical attention. Lactic acidosis with AVANDAMET is rare. The risk of lactic acidosis is higher in some patients, including the elderly, those taking doses of metformin greater than 2 g per day, those drinking excessive amounts of alcohol and those whose kidneys are not working properly.
This is not a complete list of all possible side-effects. Others may occur in some people and there may be some side-effects not yet known.
Tell your doctor or pharmacist if you notice any side effects from your medicine which are not mentioned here.
Do not be alarmed by this list of possible side-effects. You may not experience any of them.
