Janumet XR CP is indicated as an adjunct to exercise and diet to help improve glycemic (blood sugar) control in adults with type 2 diabetes mellitus.
Limitations of use:
These conditions require different treatments, as Janumet XR CP is not effective in such cases.
Janumet XR CP Boxed Warning: Lactic Acidosis
Janumet XR CP contains Metformin, which can cause lactic acidosis, a rare but serious condition that may be fatal. Postmarketing cases have reported outcomes including death, low body temperature (hypothermia), low blood pressure, and abnormal heart rhythms.
Symptoms of lactic acidosis may include:
Risk factors that increase the chance of lactic acidosis include:
If lactic acidosis is suspected, stop taking Janumet XR CP immediately and seek emergency medical care. Treatment may require hospitalization, and hemodialysis may be used to remove Metformin from the body.
The mechanism of action of Janumet XR CP involves the combined effects of sitagliptin and metformin hydrochloride extended-release.
Sitagliptin works by enhancing the levels of natural hormones called incretins. These hormones are released after meals and help the body respond better to rising blood sugar. By slowing the breakdown of incretins, Sitagliptin helps:
Metformin (Extended-Release) helps improve the body’s response to insulin over time. It works by:
Together, these effects improve daily blood glucose control without overstimulating insulin secretion.
Janumet XR CP tablet should be taken once daily, preferably in the evening, with a meal or exactly as prescribed by your healthcare provider. Taking it with food helps reduce stomach-related side effects and improves tolerability. Always follow your healthcare provider’s instructions. General guidelines include:
The dosage of Janumet XR CP tablet is individualized by a healthcare provider based on a patient’s current diabetes treatment, effectiveness, tolerability, and kidney function.
Recommended dosing:
Maximum recommended daily dose:
Starting dose considerations:
Patients with kidney impairment:
Temporary discontinuation:
Janumet XR CP may need to be stopped temporarily in certain situations, such as before imaging procedures involving iodinated contrast agents. Treatment is typically restarted once kidney function is confirmed to be stable.
If too much Janumet XR CP is taken, seek immediate medical support or contact a poison control center for guidance. An overdose may require supportive medical care, depending on the amount taken and the person’s condition. Doctors may monitor heart function and provide treatment based on symptoms.
This is because Janumet XR CP contains Metformin; taking too much can increase the risk of lactic acidosis, a rare but serious condition that requires urgent medical attention. In severe cases of Metformin overdose, hemodialysis may be used to help remove the drug from the body.
Commonly reported Janumet XR CP side effects are listed below:
These are usually mild and may improve as the body adjusts to the medication:
Low blood sugar (hypoglycemia) may occur, especially when Janumet XR CP is taken with insulin or sulfonylureas.
If any side effects bother you, last longer than expected, or worsen, contact your healthcare provider.
Some individuals may require additional monitoring when using Janumet XR CP. Always share your full medical history with your healthcare provider before starting treatment.
Before starting Janumet XR CP tablets, inform your healthcare provider about your full medical history. Extra caution may be needed in the following situations:
Pregnancy:
Limited data are available regarding the use of Janumet XR CP during pregnancy. Poorly controlled diabetes during pregnancy increases maternal and fetal risks. This medication should be used during pregnancy only if clearly needed and under medical supervision.
Breastfeeding:
Metformin is present in human breast milk in small amounts, and sitagliptin may also pass into breast milk. The benefits of breastfeeding should be weighed against the mother's need for treatment. Consult a healthcare provider before use.
Janumet XR CP may interact with medications that affect blood glucose levels or metformin clearance. Patients should inform their healthcare provider of all medications and supplements they are taking. Medications that may interact include:
| Drug Category | Clinical Impact | Drug Examples |
|---|---|---|
| Carbonic Anhydrase Inhibitors | May increase the risk of lactic acidosis | Topiramate, Zonisamide, Acetazolamide |
| Drugs That Reduce Metformin Clearance (OCT2 / MATE Inhibitors) | May increase Metformin levels and lactic acidosis risk | Cimetidine, Ranolazine, Vandetanib, Dolutegravir |
| Alcohol | Increases the effect of Metformin on lactate metabolism | Beer, wine, spirits |
| Insulin or Insulin Secretagogues | Increased risk of low blood sugar (hypoglycemia) | Insulin, Sulfonylureas |
| Drugs Affecting Blood Sugar Control | May raise or lower blood sugar levels | Diuretics, Corticosteroids, Thyroid products, Estrogens, Oral contraceptives, Calcium channel blockers |
