1. Why am I taking JANUMET?

JANUMET contains two active ingredients: sitagliptin and metformin. Sitagliptin is a member of a class of medicines you take by mouth called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors) and metformin which belongs to a class of medicines called biguanides. Sitagliptin and metformin work together to control blood sugar levels in adults with type 2 diabetes mellitus.
JANUMET is used to lower blood sugar levels in adults with type 2 diabetes mellitus. JANUMET can be taken alone or in combination with certain other medicines that lower blood sugar along with a recommended diet and exercise program.

Do not take a double dose to make up for the dose you missed.

If you take too much JANUMET

If you think that you have taken too much JANUMET, you may need urgent medical attention.
You should immediately:

contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while taking JANUMET?

Things you should do

Call your doctor straight away if you:

Become pregnant while taking JANUMET, or
Tell your doctor if you:
Become ill
Become dehydrated
Are injured
Have a fever
Have a serious infection
Plan to have 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 JANUMET with insulin.

Low blood sugar or high blood sugar

Make sure that you, your friends, family and work colleagues can recognise the symptoms of low blood sugar and high blood sugar and know how to treat them.

Low blood sugar

Signs of low blood sugar 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 low blood sugar, 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.

High blood sugar

If you notice any signs of high blood sugar, contact your doctor immediately.
The risk of high blood sugar is increased with:
uncontrolled diabetes
illness, infection or stress
taking less JANUMET than prescribed
taking certain other medicines
too little exercise
eating more carbohydrates than normal.
Your blood glucose sugar 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 JANUMET with insulin.
Stop taking JANUMET if you have symptoms of lactic acidosis, such as feeling very weak and tired, unusual (not normal) muscle pain, trouble breathing, stomach pain with nausea and vomiting, or diarrhoea, feeling cold, especially in your arms and legs, feeling dizzy or lightheaded, a slow or irregular heart beat or your medical condition suddenly changes.
Diet and exercise can help your body use its blood sugar better. It is important to stay on your doctor's recommended diet, exercise and weight loss program while taking JANUMET.
Make sure you check your blood glucose sugar levels regularly.
Visit your doctor for regular checks of your eyes, feet, kidneys, heart, circulation, blood and blood pressure.
See you doctor once a year for a check on your body's level of vitamin B12.
If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking JANUMET.
Remind any doctor, dentist or pharmacist you visit that you are taking JANUMET.
