Contents of the pack and other information
Tandemact contains pioglitazone and glimepiride which are anti-diabetic medicines, used to control blood sugar level.
It is used in adults when metformin is not suitable to treat type 2 (non-insulin dependent) diabetes mellitus. This type 2 diabetes usually develops in adulthood where the body either does not produce enough insulin (a hormone that controls blood sugar levels), or cannot effectively use the insulin it produces.
Tandemact helps control the level of sugar in your blood when you have type 2 diabetes by increasing the amount of insulin available and helping your body make better use of it. Your doctor will check whether Tandemact is working 3 to 6 months after you start taking it.
if you are allergic to pioglitazone, glimepiride, other sulphonylureas or sulphonamides, or any of the other ingredients of this medicine (listed in section 6)
if you have heart failure or have had heart failure in the past
if you have liver disease
if you have diabetic ketoacidosis (a complication of diabetes with rapid weight loss, nausea or vomiting)
if you have severe problems with your kidneys
if you have or have ever had bladder cancer
if you have blood in your urine that your doctor has not checked
if you have insulin dependent diabetes (type 1)
if you are in a diabetic coma
if you are pregnant
if you are breast-feeding
Talk to your doctor or pharmacist before taking Tandemact (see also section 4)
if you have a problem with your heart. Some patients with long-standing type 2 diabetes mellitus and heart disease or previous stroke who were treated with pioglitazone and insulin together experienced the development of heart failure. Inform your doctor as soon as possible if you experience signs of heart failure such as unusual shortness of breath or rapid increase in weight or localised swelling (oedema).
if you retain water (fluid retention) or have heart failure problems in particular if you are over 75 years old. If you take anti-inflammatory medicines which can also cause fluid retention and swelling, you must also tell your doctor.
if you have a special type of diabetic eye disease called macular oedema (swelling of the back of the eye), talk to your doctor if you notice any change to your vision.
if you have a problem with your liver. Before you start taking Tandemact you will have a blood sample taken to check your liver function. This check should be repeated at intervals. Inform
your doctor as soon as possible if you develop symptoms suggesting a problem with your liver (like feeling sick without explanations, vomiting, stomach ache, tiredness, loss of appetite and/or dark urine) as your liver function should be checked.
if you have cysts on your ovaries (polycystic ovary syndrome). There may be an increased possibility of becoming pregnant because you may ovulate again when you take Tandemact. If
this applies to you, use appropriate contraception to avoid the possibility of an unplanned pregnancy.
if you are already taking other medicines for the treatment of diabetes.
if you have problems with your enzyme called Glucose-6-phosphodehydrogenase since it can decrease your red cells.
You may also experience a reduction in blood count (anaemia). Your doctor may take blood tests to monitor your blood cell levels and liver function.
When you take Tandemact, your blood sugar could fall below the normal level (hypoglycaemia). If you experience symptoms of hypoglycaemia such as cold sweat, tiredness, headache, rapid heartbeat, hunger pangs, irritability, nervousness or nausea, you should take some sugar to increase your blood sugar level again. Ask your doctor or pharmacist for more information if you are not sure how to recognise this. It is recommended that you carry some sugar lumps, sweets, biscuits or sugary fruit juice.
A higher number of bone fractures was seen in patients, particularly women taking pioglitazone. Your doctor will take this into account when treating your diabetes.
Use in children and adolescents under 18 years is not recommended.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is because some medicines can weaken or strengthen the effect of Tandemact on the level of sugar in your blood.
The following medicines can increase the blood sugar lowering effect of Tandemact. This can lead to a risk of hypoglycaemia (low blood sugar):
gemfibrozil and fibrates (to lower high cholesterol level)
insulin, metformin or other medicines to treat diabetes mellitus
phenylbutazone, azapropazone, oxyphenbutazone, aspirin-like medicines (to treat pain and inflammation)
long acting sulphonamides, tetracyclines, chloramphenicol, fluconazole, miconazole,
quinolones, clarithromycin (to treat bacterial or fungal infections)
anabolic steroids (supporting muscle build up) or male sex hormone replacement therapy
fluoxetine, MAO-inhibitors (to treat depression)
angiotensin-converting enzyme (ACE) inhibitors, sympatholytics, disopyramide, pentoxifylline, coumarin derivatives such as warfarin (to treat heart or blood problems)
allopurinol, probenecid, sulfinpyrazone (to treat gout)
cyclophosphamide, ifosfamide, trofosfamide (to treat cancer)
fenfluramine (to reduce weight)
tritoqualine (to treat allergies)
The following medicines may decrease the blood sugar lowering effect of Tandemact. This can lead to a risk of hyperglycaemia (high blood sugar level):
oestrogens, progestogens (female sex hormones)
thiazide diuretics and saluretics also called water tablets (to treat high blood pressure)
levothyroxine (to stimulate the thyroid gland)
glucocorticoids (to treat allergies and inflammation)
chlorpromazine and other phenothiazine derivatives (to treat severe mental disorders)
adrenaline and sympathicomimetics (to increase heart beat, to treat asthma or nasal congestion, coughs and colds or used in life-threatening emergencies)
nicotinic acid (to treat high cholesterol level)
long-term use of laxatives (to treat constipation)
phenytoin (to treat fits)
barbiturates (to treat nervousness and sleep problems)
azetazolamide (to treat increased pressure in the eye also called glaucoma)
diazoxide (to treat high blood pressure or low blood sugar)
rifampicin (to treat infections, tuberculosis)
glucagon (to treat severe low blood sugar levels)
The following medicines can increase or decrease the blood sugar lowering effect of Tandemact:
H2 antagonists (to treat stomach ulcers)
beta-blockers, clonidine, guanethidine and reserpine (to treat high blood pressure or heart
failure). These can also hide the signs of hypoglycaemia, so special care is needed when taking these medicines
Tandemact may either increase or weaken the effects of the following medicines:
coumarin derivatives such as warfarin (to slow down or stop blood clotting)
Tell your doctor or pharmacist if you are taking any of these. Your blood sugar will be checked, and your dose of Tandemact may need to be changed.
Avoid alcohol while taking Tandemact since alcohol may increase or decrease the blood sugar lowering action of Tandemact in an unpredictable way.
Do not use Tandemact if you are pregnant. You must tell your doctor if you are, you think you may be pregnant or are planning to have a baby. Your doctor will advise you to discontinue this medicine.
Do not use Tandemact if you are breastfeeding or are planning to breast-feed (see section “Do not take
Tandemact”).
Alertness and reaction time may be impaired due to low or high blood sugar due to glimepiride, especially when beginning or after altering treatment, or when Tandemact is not taken regularly. This may affect your ability to drive or use machines.
Take care if you experience abnormal vision.
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking Tandemact.

may include cold sweat, tiredness, headache, rapid heartbeat, hunger pangs, irritability, nervousness, nausea, coma or convulsion. Your blood sugar level can be increased by taking sugar. It is
recommended that you carry some sugar lumps, sweets, biscuits or sugary fruit juice.
Take Tandemact daily as prescribed. However if you miss a dose, skip the missed dose and just carry on with the next dose as normal. Do not take a double dose to make up for a forgotten tablet.
Tandemact should be used every day to work properly. If you stop using Tandemact, your blood sugar may go up. Talk to your doctor before stopping this treatment.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
