What is in this leaflet
This leaflet answers some common questions about JANUVIA. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking JANUVIA against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may need to read it again.
What JANUVIA is used for
JANUVIA is used to lower blood sugar levels in patients with type 2 diabetes mellitus in combination with certain other medicines (metformin, medicines such as rosiglitazone and pioglitazone, or a sulfonylurea medicine such as glimepiride and glibenclamide), when diet plus exercise plus the single medicine do not provide adequate blood sugar level control.
Type 2 diabetes mellitus
Type 2 diabetes mellitus is a condition in which your body does not make enough insulin and the insulin that your body produces does not work as well as it should. Your body can also make too much sugar.
When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems.
The main goal of treating diabetes is to lower your blood sugar to a normal level. Lowering and controlling blood sugar may help prevent or delay complications of diabetes, such as heart disease, kidney disease, blindness and amputation.
High blood sugar can be lowered by diet and exercise and by certain medicines.
How JANUVIA works
JANUVIA is a member of a class of medicines you take by mouth called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors) that lowers blood sugar levels in patients with type 2 diabetes mellitus. Type 2 diabetes mellitus is also called non-insulin-dependent diabetes mellitus, or NIDDM.
JANUVIA helps to improve the levels of insulin after a meal.
JANUVIA decreases the amount of sugar made by the body.
JANUVIA works when blood sugar is high, especially after a meal. This is when the body needs the greatest amount of help in lowering blood sugar. JANUVIA also lowers blood sugar between meals.
JANUVIA by itself is unlikely to cause low blood sugar (hypoglycaemia) because it does not work when your blood sugar is low.

How to take JANUVIA
How much to take
Take JANUVIA only when prescribed by your doctor.
The recommended dose is to take:
one 100 mg tablet
once a day
by mouth, with or without food
If you have kidney problems, your doctor may prescribe lower doses.
Your doctor may prescribe JANUVIA along with certain other medicines that lower blood sugar.
Follow all directions given to you by your doctor and pharmacist carefully.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
When to take it
Take your JANUVIA at about the same time each day.
Taking your tablet(s) at the same time each day will have the best effect. It will also help you remember when to take the tablets.
How long to take it
Continue to take JANUVIA as long as your doctor prescribes it so you can continue to help control your blood sugar.
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 JANUVIA.
If you forget to take it
If you miss a dose, take it as soon as you remember. If you do not remember until it is time for your next dose, skip the missed dose and go back to your regular schedule.
If you are not sure whether to skip the dose, talk to your doctor or pharmacist.
Do not take a double dose of JANUVIA to make up for the dose that you missed.
If you have trouble remembering to take your tablet, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have taken too much JANUVIA. Do this even if there are no signs of discomfort or poisoning.
While you are using JANUVIA
Things you must do
If you become pregnant while taking JANUVIA, tell your doctor immediately.
If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking JANUVIA.
Things you must not do
Do not give JANUVIA to anyone else, even if they have the same condition as you.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking JANUVIA.
Like all prescription medicines, JANUVIA may cause side effects. In studies, side effects usually were mild and did not cause patients to stop taking JANUVIA.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice or have any of the following and they worry you:
signs of an infection of the breathing passages, including runny nose, sore throat, cough
soreness in the back of the nose and throat and discomfort when swallowing
JANUVIA may occasionally cause stomach discomfort and diarrhoea.
Tell your doctor immediately if you notice any of the following:
Low blood sugar (hypoglycaemia) when JANUVIA is used in combination with a sulfonylurea medicine. Due to the sulfonylurea, causing hypoglycaemia, the dose of your sulfonylurea medicine may need to be reduced while you use JANUVIA.
Allergic reactions which may be serious including rash, hives, and swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing. If you have an allergic reaction, stop taking JANUVIA and call your doctor right away. Your doctor may prescribe a medication to treat your allergic reaction and a different medication for your diabetes.
Other side effects not listed above may also occur in some patients. Tell your doctor if you notice any other effects.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
After using JANUVIA
Keep your tablets in the blister pack until it is time to take them.
If you take the tablets out of the blister pack they may not keep well.
Keep JANUVIA in a cool dry place where the temperature stays below 30°C. Do not store it or any other medicine in the bathroom or near a sink.
Do not leave it in the car or on window sills.
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 JANUVIA or the tablets have passed their expiry date, ask your pharmacist what to do with any that are left over.
