What Trajentamet is used for

Trajentamet is used to lower blood sugar levels in patients with type 2 diabetes mellitus.

It may be used when diet plus exercise do not provide adequate blood sugar level control either:

  • alone as a single medicine, or
  • in combination with certain other anti-diabetic medicines such as:
    – sulfonylurea medicines such as glimepiride and glibenclamide, or
    – insulin, or
    – sodium-glucose transporter 2 inhibitor medicines such as empagliflozin.

Type 2 diabetes mellitus is also called non-insulin-dependent diabetes mellitus or NIDDM. Type 2 diabetes mellitus develops if the body does not make enough insulin or if the insulin that your body makes does not work as well as it should.

Insulin is a substance which helps to lower the level of sugar in your blood, especially after meals.

When the level of sugar builds up in your blood, this can cause damage to the body’s cells and lead to serious problems with your heart, brain, eyes, circulation, nerves or kidneys.

How Trajentamet works

Trajentamet contains two different active substances, linagliptin and metformin.

Linagliptin belongs to a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors). Metformin belongs to a class of medicines called biguanides.

Trajentamet helps to improve the levels of insulin after a meal and lowers the amount of sugar made by your body.

Lowering and controlling blood sugar may help prevent or delay complications of diabetes, such as heart disease, kidney disease, blindness and foot amputation.

Both medicines work together to control blood sugar in patients with Type 2 diabetes mellitus.

Along with diet and exercise, this medicine helps lower your blood sugar.

Your doctor may have prescribed Trajentamet to replace the antidiabetic medicine(s) you are currently taking. It is important that you continue to follow the diet and/or exercises recommended for you while you are on treatment with Trajentamet.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor’s prescription. It is not addictive.

Before you take Trajentamet

When you must not take it

Do not take Trajentamet if you have an allergy to:

  • any medicine containing linagliptin or metformin
  • any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin.

Do not take Trajentamet if you:

  • have any type of metabolic acidosis such as lactic acidosis, diabetic ketoacidosis (a symptom of uncontrolled diabetes, in which substances called ketone bodies build up in the blood – you may notice this as an unusual fruity odour on your breath, difficulty breathing, confusion and frequent urination)
  • have had a diabetic pre-coma
  • have problems with your kidneys
  • have liver problems
  • have a severe infection
  • are dehydrated
  • are treated for acute heart failure or have recently had a heart attack
  • have severe problems with your circulation (such as shock)
  • have severe breathing difficulties
  • have blood clots in the lungs (symptoms include coughing, shortness of breath, chest pain and a fast heart rate)
  • have significant blood loss
  • have gangrene
  • have inflammation of the pancreas (pancreatitis), symptoms include severe upper stomach pain, often with nausea and vomiting
  • drink excessive alcohol (all the time or “binge” drinking).

Talk to your doctor about when to stop taking Trajentamet and when to start taking it again if you:

  • are going to have an x-ray where you will be injected with an iodinated contrast (dye)
  • are planning to have surgery (including where the use of insulin is essential).

Do not take this medicine if you are pregnant or intending to become pregnant. It may affect your developing baby if you take it during pregnancy.

Do not breast-feed if you are taking this medicine. One of the active substances in Trajentamet, metformin, is known to pass into human breast milk. It is not known if the other active substance, linagliptin passes into human breast milk and could affect your baby.

Do not give this medicine to a child under the age of 18 years. Safety and effectiveness in children younger than 18 years have not been established.

Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Discard any other medicines containing metformin or linagliptin that your doctor might have prescribed to you in the past and that you may still have in your possession. Trajentamet contains linagliptin and metformin. If you have more than one metformin-containing medicine in your possession you may accidentally take too much (overdose). Accidentally taking too much metformin can cause a very serious side effect called lactic acidosis.


Ask your doctor or pharmacist if you are unsure if you have any other medicines containing metformin. Metformin is sold under many different brand names in Australia. Your doctor or pharmacist will know which other medicines also contain metformin.

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes. Your doctor can discuss with you the risks and benefits involved.

Tell your doctor if you have type 1 diabetes, a condition where your body does not produce any insulin. Trajentamet should not be used to treat type 1 diabetes.

If you have not told your doctor, pharmacist or diabetes educator about any of the above, tell them before you take Trajentamet.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and Trajentamet may interfere with each other. These include:

  • an antibiotic used to treat certain infections such as tuberculosis (rifampicin)
  • a medicine used to treat reflux and ulcers (cimetidine)
  • medicines used to control fits (seizures), chronic pain or glaucoma (carbamazepine, phenobarbital, phenytoin, topiramate, zonisamide, acetazolamide, dichlorphenamide)
  • medicines used to treat diseases that involve inflammation, like asthma and arthritis (corticosteroids)
  • specific medicines for the treatment of high blood pressure (ACE inhibitors, angiotensin II receptor antagonists, calcium channel blockers, beta blockers)
  • medicines used to prevent blood clots, such as warfarin
  • medicines which increase urine production (diuretics)
  • some medicines used to treat asthma (salbutamol or terbutaline)
  • medicines used to relieve pain, swelling and other symptoms of inflammation (NSAIDs (non-steroidal anti-inflammatory drugs) such as aspirin, diclofenac, ibuprofen, meloxicam, naproxen or piroxicam, and selective COX II inhibitors such as celecoxib, parecoxib, etoricoxib)
  • iodinated contrast agents (which you may receive while having an X-ray)
  • alcohol-containing medicines
  • a medicine used in people with multiple sclerosis, and in young children to treat some types of seizures (fits) (tetracosactrin)
  • a medicine used to treat endometriosis (danazol)
  • a medicine used to treat schizophrenia and other mental illnesses (chlorpromazine)
  • medicines used in the treatment of HIV and chronic hepatitis C infections (dolutegravir, daclatasvir)
  • medicines used in the treatment of certain cancers (crizotinib, olaparib, vandetanib).

These medicines may be affected by Trajentamet or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor, pharmacist or diabetes educator can tell you what to do if you are taking any of these medicines. They also have more information on medicines to be careful with or avoid while taking this medicine.

How to take Trajentamet

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How much to take

Your doctor will tell you how many Trajentamet tablets to take and how often you should take them.

The usual dose is one Trajentamet tablet twice daily.

Take Trajentamet exactly as your doctor or pharmacist has told you.

Your doctor will prescribe Trajentamet alone or in combination with another anti-diabetic medicine if that medicine alone is not sufficient to control your blood sugar level.

How to take it

Swallow the tablet whole with a full glass of water during or after meals. This will lessen the chance of a stomach upset.

When to take it

Take your medicine at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

How long to take it

Continue taking Trajentamet for as long as your doctor tells you to. Make sure you keep enough Trajentamet to last over weekends and holidays.

Trajentamet will help control your diabetes, but will not cure it. Therefore, you may have to take it for a long time.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Trajentamet. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are taking Trajentamet

Things you must do

If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking Trajentamet.

Tell any other doctors, dentists and pharmacists who treat you that you are taking Trajentamet.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking Trajentamet. It may affect other medicines used during surgery such as, iodinated contrast agents (which you may receive while having an X-ray).

If you are intending to become pregnant or are pregnant talk to your doctor about alternative medications to control your blood glucose level. It is important your blood glucose levels are as close to normal as possible at this time.

Keep all of your doctor’s appointments so that your progress can be checked. Your doctor may want to perform blood tests to check your kidneys and vitamin B12 levels while you are taking Trajentamet.

Follow your doctor’s and/ or dietician’s advice on diet, drinking alcohol and exercise. Diet and exercise can help your body use its blood sugar better. It is important to stay on the diet and exercise program recommended by your doctor while taking Trajentamet.

Make sure you check your blood glucose levels regularly. This is the best way to tell if your diabetes is being controlled properly. Your doctor or diabetes educator will show you how and when to do this.

Tell your doctor if you become ill or dehydrated, or experience stress, injury, fever, infection, or need surgery. Your blood glucose may become difficult to control at these times. You may also be at greater risk of developing a serious condition called lactic acidosis. During these times, your doctor may temporarily replace Trajentamet with insulin.

Make sure that you, your friends, family and work colleagues can recognise the symptoms of hypoglycaemia and hyperglycaemia and know how to treat them.


Trajentamet does not normally cause hypoglycaemia, although you may experience it if you take certain other medicines.

Signs of hypoglycaemia may include:

  • weakness, trembling or shaking
  • sweating
  • light-headedness, dizziness, headache or lack of concentration
  • irritability, tearfulness or crying
  • hunger
  • numbness around the lips and tongue.

If not treated quickly, these symptoms may progress to:

  • loss of co-ordination
  • slurred speech
  • confusion
  • fits or loss of consciousness.

At the first signs of hypoglycaemia, you need to raise your blood glucose quickly.

You can do this by taking one of the following:

  • 5 -7 jelly beans
  • 3 teaspoons of sugar or honey
  • half a can of non-diet soft drink
  • 2-3 concentrated glucose tablets.

Unless you are within 10 to 15 minutes of your next meal or snack, follow up with extra carbohydrates such as plain biscuits, fruit or milk. Taking this extra carbohydrate will prevent a second drop in your blood glucose level.


If you notice the return of any signs of hyperglycaemia, contact your doctor immediately. The risk of hyperglycaemia is increased in the following situations:

  • uncontrolled diabetes
  • illness, infection or stress
  • taking less Trajentamet than prescribed
  • taking certain other medicines
  • too little exercise
  • eating more carbohydrates than normal.

Things you must not do

Do not take Trajentamet to treat any other complaints unless your doctor tells you to.

Do not give this medicine to anyone else, even if they have the same condition as you.

Do not stop taking your medicine or lower the dosage without checking with your doctor.

Things to be careful of

Be careful driving or operating machinery until you know how Trajentamet affects you. You may experience dizziness when taking Trajentamet.

If your blood sugar level becomes too low, you may feel dizzy, weak or tired and your reaction time may be slower than usual. Other symptoms of low blood sugar are listed under Side effects.

If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.

Be careful when doing any of the following things, which increase the risk of your blood glucose becoming too low:

  • drinking alcohol
  • not eating enough
  • doing unexpected or vigorous exercise.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Trajentamet.

This medicine helps most people with type 2 diabetes mellitus, but it may have unwanted side effects in a few people.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Do not be alarmed by the following lists of side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • swelling of the nose or throat (nasopharyngitis)
  • cough
  • loss in appetite
  • nausea, vomiting
  • loss of taste
  • mouth ulceration
  • constipation
    Constipation may occur in patients who already take another medication to treat diabetes, such as insulin.
  • diarrhoea
  • painful, swollen joints
  • aching muscles, muscle tenderness or weakness, not caused by exercise
  • weight gain

Tell your doctor as soon as possible if you notice any of the symptoms of low blood sugar such as:

  • sweating
  • weakness
  • hunger
  • dizziness
  • trembling
  • headache
  • flushing or paleness
  • numbness
  • a fast, pounding heartbeat.

Low blood sugar may occur in patients who already take another medication to treat diabetes, such as a sulfonylurea or insulin. The dose of your sulfonylurea or insulin medicine may need to be reduced while taking Trajentamet.

Tell your doctor immediately if you develop blisters or the breakdown of the outer layer of your skin (erosion). These may be signs of a skin reaction called bullous pemphigoid. Your doctor may tell you to stop taking Trajentamet.

Tell your doctor immediately or go to Emergency if you notice any of the following:

  • sudden onset of hives, itching or skin rash
  • swelling of the face, lips or tongue which may lead to difficulty swallowing or breathing
  • severe upper stomach pain radiating to the back, nausea, vomiting and fever (which may be symptoms of an inflamed pancreas – pancreatitis).

Stop taking Trajentamet if you get any of the following symptoms of lactic acidosis and go to Emergency immediately:

  • feeling cold (especially in your arms and legs)
  • feeling very weak, tired
  • feeling light-headed, dizzy
  • severe nausea or vomiting
  • feeling uncomfortable
  • muscle pain
  • drowsiness
  • abdominal pain
  • unexplained weight loss
  • irregular heartbeat
  • rapid or difficult breathing.

In rare cases, metformin, one of the active substances in Trajentamet can cause a serious side effect called lactic acidosis.

This is a medical emergency that can cause death. It is caused by build-up of lactic acid in your blood.

The above list includes very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are very rare.

Tell your doctor or pharmacist if you notice anything else that is making you feel unwell. Other side effects not listed above may also occur in some people.

Some of these side effects can only be found when your doctor does tests from time to time to check your progress.

After taking Trajentamet


Keep your tablets in the pack until it is time to take them. If you take the tablets out of the pack they may not keep well.

Keep your tablets in a cool dry place where the temperature stays below 30°C.

Do not store Trajentamet or any other medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.

Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking this medicine or the expiry date has passed, ask your pharmacist what to do with any medicine that is left over.
