Januvia is a medicine used to treat type 2 diabetes. Diabetes is a long-term condition that causes blood sugar to become too high. Januvia works by lowering blood sugar levels in diabetic patients.

    What is Januvia?

    Januvia is a daily medicine that, along with diet and regular exercise, helps lower blood sugar levels in adults with type 2 diabetes and can be used alongside other prescription drugs.

    Januvia contains sitagliptin phosphate, an active substance which is part of a class of medicines called dipeptidyl peptidase-4 (DPP-4) inhibitors. Sitagliptin is a prescription medication that works by increasing the levels of natural substances called incretins which help control the release of insulin.

    Diabetes can be maintained with a healthy lifestyle. Proper control of diabetes is important as it lessens your risk of kidney damage, heart attack, stroke and nerve damage.

    For further information on Januvia, please see the patient information leaflet.

    How It Works

    After a meal, the glucose spikes to a temporarily high blood sugar level that will start soon after eating. In a person with type 2 diabetes, the body may not produce enough insulin, a hormone that regulates the movement of sugar into the cells, to maintain and help lower the amount of sugar in the blood to healthy glucose levels.

    The risk of hypoglycemia is unlikely as Januvia works along with your body to enhance its own ability to lower blood sugar made by the liver and will be effective only if it is needed. If you do present symptoms of low blood sugar levels, ask your doctor for medical advice on a treatment most suitable for you.

    A healthy lifestyle of a balanced diet and regular exercise are essential while managing diabetes, as medication alone does not substitute the added benefits of a good diet and exercise. People who practise a healthy lifestyle have a higher chance of getting better control of their diabetes.

    Before you take it

    Januvia is suitable for people who have type 2 diabetes only. Type 2 diabetes is characterised by high blood sugar, insulin resistance and lack of insulin. Januvia should not be used in patients with type 1 diabetes.

    Most healthy adults over the age of 18 years old can take Januvia. It is unknown if this medication is safe to treat children and adolescents under the age of 18 and should therefore not be used in such instances. It is not recommended to take treatment without the supervision of a doctor or registered medical practitioner. We do not prescribe any medications to people under the age of 18 years old.

    It is important for your own health and safety that if you already suffer symptoms of serious allergic reactions related to sitagliptin or any other ingredient in this drug, you should talk to your doctor if you have a concern about any ingredients in this treatment.

    Januvia is unsuitable for some patients. You should contact your doctor or healthcare professional if any of the following apply:

    • You have ever had pancreatitis (a disease of the pancreas)
    • You suffer gallstones or high levels of triglycerides in the blood
    • Have type 1 diabetes
    • You have ever had heart failure
    • Are in diabetic ketoacidosis (a complication of diabetes where there are too many ketones in the blood if there is not enough insulin)
    • Have or have had problems with your kidneys
    • Regularly drink more than the recommended maximum amount of 14 units of alcohol per week

    Dosage Instructions

    This medication can be taken with water and can be administered with or without food. If you have problems with your kidney, it is likely your doctor may prescribe a lower dose and can best advise you how to take Januvia.

    The recommended dose of Januvia is one 100 mg tablet taken orally, once a day.

    It is recommended for people who take Januvia to administer the dosage at the same time every day. This helps avoid double dosing and forgetting to take the medicine.
