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
alone as a single medicine, or
in combination with certain other anti-diabetic medicines such as:
sulfonylurea medicines such as glimepiride and glibenclamide, 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
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
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
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
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription. It is not addictive.

rash, itching or hives on the skin.
Do not take Trajentamet if you:

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.
ACCIDENTAL METFORMIN OVERDOSING IS A SIGNIFICANT SAFETY RISK.

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.

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

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.

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
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking
It may affect other medicines used during surgery such as, iodinated contrast agents
(which you may receive while having an X-ray).
If you become pregnant while taking this medicine, tell your doctor immediately.
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
light-headedness, dizziness, headache or lack of concentration
irritability, tearfulness or crying
numbness around the lips and tongue.
If not treated quickly, these symptoms may progress to:
loss of co-ordination
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:
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
Do not give this medicine to anyone else, even if they have the same condition as
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:
not eating enough
doing unexpected or vigorous exercise.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you
are taking Trajentamet.

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

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

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.
