Diabetes Medications and New Drugs

Janumet (Januvia / Metformin)

What is Janumet?

Janumet is a combination tablet which combines two diabetes medications Januvia (Sitagliptin) and Metformin in a single tablet.

Why combine two drugs in one tablet?

The only reason to combine two drugs in this way is for your convenience. If you would prefer to take the doses separately there is no reason why you shouldn’t.

It is important to recognise that the combination tablet does not offer any improvement in blood glucose lowering efficacy. However, there may be an advantage in combining the two drugs as there is evidence that the blood glucose lowering potential of the combined tablet may be greater than that of each drug taken individually.

What strengths of Janumet are available?

It is likely that JanuMet will be available in two preparations.

Januvia 50 mg + Metformin 500 mg

Januvia 50 mg + Metformin 1000 mg

Is Janumet available in the UK?

Both Januvia and Metformin are available for prescription separately in the UK. The combination tablet has yet to be launched. The Food and Drug Administration in the United States has approved Janumet for use in adults with type 2 diabetes.

Where can I find more information?

You can read more about Januvia and Metformin on the separate web pages for those individual drugs.
