What is Janumet XR Used For? Side Effects and Dosing
What is Janumet XR used for?
Janumet XR is an oral extended release tablet that contains two drugs, i.e. sitagliptin and metformin. An extended-release tablet is normally released slowly into the bloodstream over a certain period of time. It can be used alone or in combination with other diabetes drugs. The 2 drugs in this extended-release tablet work in synergy to control blood glucose levels. Sitagliptin works by increasing incretins. This natural substance helps to control blood glucose by increasing the amount of insulin that is released after eating. Incretins also work by reducing the amount of glucose that is produced by the liver. On the other hand, metformin helps to increase your body’s sensitivity to insulin. Metformin also reduces the amount of glucose that is produced by the liver, and the glucose that is absorbed by the intestines. Janumet XR is normally prescribed together with diet and exercise to treat high levels of blood sugar in patients with type 2 diabetes. It is important to control high levels of blood sugar in patients with type 2 diabetes, so as to prevent complications such as nerve damage, kidney problems, blindness, and loss of limbs. However, this medication should not be used to treat patients with type 1 diabetes or diabetic ketoacidosis. Do not take this medicine if you are allergic to any of its ingredients.
The dosage of this prescription drug will vary depending on your medical condition, other drugs you are using, and how you respond to treatment. To lower the chance of side effects, your health-care provider may ask you to start taking Janumet XR at a lower dose and increase your dose gradually. The drug comes in dose strengths of 100mg sitagliptin/1000mg metformin, 50mg sitagliptin/500mg metformin, and 50mg sitagliptin/1000mg metformin. For diabetic patients who are not currently taking metformin, the starting dose is 1 tablet that contains 100mg sitagliptin/1000mg metformin to be taken once every day with dinner. Your health-care provider may gradually increase your dosage if needed. This medication should be taken orally as advised by your health-care provider. Make sure you don’t chew or crush the extended release tablet. Crushing or chewing Janumet XR may release the drugs contained in it all at once, which increases the chance of side effects. Instead swallow the whole tablet.
