Uses of Janumet Tablets
Janumet (Sitagliptin and Metformin tablets) is an oral anti diabetic medication for type 2 diabetes, that helps to control blood sugar levels. It also helps regulate post prandial (after meals) insulin levels in the body. Janumet increases the secretion of naturally produced Incretin hormones in the body.
Metformin helps to restore body's proper response to the insulin naturally produced in the body. It also decreases the amount of sugar that your liver makes and, that your stomach/intestines absorb.
Janumet Tablets – Dosage
Janumet (Sitagliptin and Metformin tablets) is indicated in conjunction with diet and exercise, to improve glycemic control in adults with type 2 diabetes mellitus, when treatment with both Sitagliptin and Metformin is appropriate.
The dosage of Janumet tablets varies on the basis of the patient's current routine, effectiveness, and tolerability. The maximum recommended dosage for Janumet tablets in a day is 100 mg of Sitagliptin and 2000 mg of Metformin hydrochloride. The initial combination therapy, or maintenance of combination therapy should be individualized and needs to be determined by the physician. It is usually prescribed with following adult dosages options.
1. Sitagliptin (50 mg) + Metformin (500mg)
2. Sitagliptin (50 mg) + Metformin (1000 mg)
Janumet tablets should generally be given twice daily with meals, with gradual dose escalation, to reduce the gastrointestinal (GI) side effects.
Janumet dosage needs to be determined in patients already taking sitagliptin or metformin individually as separate drugs. Since Janumet is a combination of both Sitagliptin and Metformin a proper dose adjustment is required to be strictly considered to the patient by the physician.
Mechanism of Action
Janumet contains Sitagliptin and Metformin HCl. Sitagliptin which is present in Janumet reduces blood sugar (glucose) levels in patients with type 2 diabetes, by acting to preserve incretin hormones released naturally in the body. After a meal, Incretin hormones (GIP 1 and GIP 2) are released by the intestine, and their levels increase in the blood.
Incretin hormones reduce blood glucose by increasing the production, and release of insulin from the pancreas. Incretin hormones also reduce blood glucose by reducing the secretion of Glucagon (hormone that increases the production of glucose by the liver and raises the blood glucose levels) from pancreas. The net effect of increased release of Incretin hormones is to reduce blood glucose levels.
Sitagliptin also inhibits the enzyme DPP-4, that destroys Incretin hormones, and thereby increasing the level and activity of Incretin hormones. As a result, blood glucose levels fall. To summarize, Sitagliptin reduces blood glucose levels by inhibiting DPP-4 and increases the levels of Incretin hormones.
The Metformin part of the medication reduces hepatic glucose production, decreasing intestinal absorption of glucose, and improving insulin sensitivity by increasing peripheral glucose uptake and utilization.

Warnings and Precautions to be taken when using Janumet Tablets (Sitagliptin and Metformin Tablets)
Before using Janumet Tablets (Sitagliptin and Metformin tablets) please inform your doctor about all the medicines that you take including no prescription medications, over the counter medicines and herbal remedies. Lactic acidosis is a rare, but serious metabolic complication that can occur due to metformin accumulation during treatment with Janumet. Lactic acidosis is a medical emergency that has to be treated in a hospital.
The risk of lactic acidosis increases with age and degree of renal dysfunction. Renal function monitoring is advised. Janumet should be stopped immediately in the presence of any condition associated with hypoxemia, dehydration, or sepsis. Excessive alcohol intake should be avoided, when taking Janumet. Since alcohol potentiates the effects of metformin hydrochloride on lactate metabolism.
A few patients may show allergic reaction to Janumet, thus it is important to get an allergic test done to check, if the patient is susceptible to any kind of allergic reaction to Janumet.
If symptoms of allergic reactions (including rash, hives, and swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing) occur, patients should stop taking Janumet tablets and seek medical advice immediately.
Janumet should be temporarily discontinued prior to any intravascular radio contrast study and before any surgical procedure.
A few instances of fatal and non-fatal pancreatitis have been reported following use of Janumet.
Janumet intake with other anti-diabetic medications or excessive use may lead to hypoglycemia (low blood sugar). Thus it is advised to get a regular blood sugar level check while taking the drug.
In pregnancy Janumet should be taken only, if clearly needed (consult a physician before use). Nursing mothers should take Janumet only after a physician’s consultation.
Keep away from children.
Side Effects of Janumet Tablets
Janumet tablets are usually well tolerated. But in a few cases it is recommended to get medical help, if any of the following possible side effects of Janumet tablets (Sitagliptin and Metformin tablets) occur after Janumet tablet intake.
- Upper respiratory tract infections
- Gastrointestinal adverse reactions
- Hypoglycaemia on concomitant use with other anti-diabetic drugs
- Allergic reactions
Janumet Tablets – Drug Interactions
Cationic drugs (e.g. Amiloride, Digoxin, Morphine, Procainamide, Quinidine, Quinine, Ranitidine, Triamterene, Trimethoprim, or Vancomycin) that are eliminated by renal tubular secretion (kidney) have the potential for interaction with Janumet (Sitagliptin and Metformin tablets) by competing for common renal tubular transport systems.
Thus careful patient monitoring and dose adjustment of Janumet is recommended in patients who are taking cationic medications.
Furosemide on being administered with Janumet leads to a considerable increase in the plasma concentration of Janumet. Dose adjustment is thus recommended.
Nifedipine on being administered with Janumet leads to increased absorption of Janumet. Dose adjustment is thus recommended.
