While Janumet is generally considered safe and effective when used as prescribed, it does carry some potential risks and side effects. It’s important to be aware of these risks and discuss them with your healthcare provider before starting the medication. Here are some of the key risks associated with Janumet:

  • Hypoglycemia: Janumet, especially when used in combination with other blood sugar-lowering medications, can potentially cause low blood sugar levels (hypoglycemia). This can result in symptoms such as dizziness, shaking, sweating, confusion, and in severe cases, loss of consciousness. It’s important to monitor blood sugar levels closely and follow your healthcare provider’s instructions to prevent and manage hypoglycemia.
  • Gastrointestinal side effects: Janumet can cause gastrointestinal side effects such as nausea, vomiting, diarrhea, and abdominal discomfort. These side effects are generally mild and temporary, but if they persist or become severe, it’s important to notify your doctor.
  • Lactic acidosis: Although rare, metformin, one of the active ingredients in Janumet, can cause a serious condition called lactic acidosis. Lactic acidosis is characterized by the buildup of lactic acid in the blood and can be life-threatening. It is more likely to occur in individuals with kidney or liver problems, severe infections, dehydration, or those undergoing certain medical procedures. Symptoms may include muscle pain, weakness, difficulty breathing, irregular heartbeat, and unusual fatigue. Seek immediate medical attention if you experience any of these symptoms.
  • Pancreatitis: There have been reports of inflammation of the pancreas (pancreatitis) in individuals taking Janumet. Symptoms may include severe abdominal pain that may radiate to the back, nausea, and vomiting. If you experience these symptoms, seek medical help promptly.
  • Allergic reactions: Some people may experience allergic reactions to Janumet, characterized by symptoms like rash, itching, swelling, severe dizziness, and difficulty breathing. If you develop any signs of an allergic reaction, seek immediate medical attention.

It’s important to note that this list does not include all possible side effects or risks associated with Janumet. Individual reactions may vary, and it’s essential to consult your healthcare provider for a comprehensive understanding of the potential risks and benefits of the medication based on your specific medical history and condition.

Why is this medication prescribed?

Janumet is prescribed to treat type 2 diabetes. It is a combination medication that contains two active ingredients: sitagliptin and metformin.

Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor. It works by increasing the levels of incretin hormones in the body, which help regulate blood sugar levels. By inhibiting the DPP-4 enzyme, sitagliptin prolongs the action of these hormones, which in turn helps to stimulate insulin release and reduce the production of glucose by the liver. Metformin, on the other hand, is a biguanide medication that improves the way the body responds to insulin and reduces the amount of glucose produced by the liver. It also increases the uptake and utilization of glucose by the body’s tissues.

By combining sitagliptin and metformin in Janumet, the medication addresses multiple aspects of blood sugar control. It helps to lower blood sugar levels, especially after meals, by increasing insulin release, reducing glucose production, and enhancing the body’s sensitivity to insulin. Janumet is typically prescribed when lifestyle changes, such as diet and exercise, alone are not sufficient to manage blood sugar levels in individuals with type 2 diabetes. It is often used as part of a comprehensive treatment plan that includes diet, exercise, and other medications to help improve glycemic control and manage the condition effectively.

How should this medicine be used?

The exact dosage and usage instructions for Janumet may vary depending on individual factors and the advice of your healthcare provider. It is essential to follow your doctor’s instructions and the prescribing information provided with the medication. However, here is a general overview of how Janumet is commonly used:

  • Timing: Janumet is usually taken twice daily, with meals (typically breakfast and dinner), or as directed by your healthcare provider. Taking it with food helps reduce the risk of stomach upset or other gastrointestinal side effects.
  • Dosage: The strength of Janumet tablets can vary, so it’s important to take the specific dosage prescribed by your doctor. The tablet may contain different amounts of sitagliptin and metformin, such as 50/500 mg, 50/850 mg, or 50/1000 mg. The numbers represent the milligrams of sitagliptin and metformin, respectively, in each tablet.
  • Swallowing: Janumet tablets should be swallowed whole with a glass of water. Do not crush, chew, or split the tablets unless advised by your doctor.
  • Other medications: If you are taking other medications, including over-the-counter products or supplements, inform your healthcare provider, as some drugs may interact with Janumet.

Remember, the information provided here is for general guidance, and it’s crucial to consult your healthcare provider or pharmacist for personalized instructions and recommendations regarding the use of Janumet. They will consider your specific health condition and medical history to determine the most appropriate dosage and usage regimen for you.

Other uses for this medicine

Janumet is primarily used for the management of type 2 diabetes. However, it is important to note that medications should only be used for their approved indications. Janumet should not be used for any other purposes unless specifically prescribed by a healthcare professional.

What special precautions should I follow?

Regarding special precautions, here are some important points to consider when taking Janumet:

  • Allergies: Inform your doctor if you have any known allergies to sitagliptin, metformin, or any other ingredients in Janumet. Allergic reactions can include rash, itching, swelling, severe dizziness, or difficulty breathing.
  • Medical conditions: Provide your healthcare provider with a comprehensive medical history, especially if you have or have had kidney problems, liver disease, pancreatitis, heart failure, or any other serious medical conditions. These conditions may affect the safe use of Janumet or require adjustments in dosage.
  • Kidney function: Janumet contains metformin, and impaired kidney function can affect the elimination of this drug from the body. Your doctor may need to monitor your kidney function regularly and adjust the dosage of Janumet accordingly.
  • Lactic acidosis: Metformin, one of the components of Janumet, can rarely cause a serious condition called lactic acidosis. It is more likely to occur in individuals with kidney or liver problems, severe infections, dehydration, or those undergoing certain medical procedures. Inform your doctor immediately if you experience symptoms such as muscle pain, weakness, rapid breathing, unusual tiredness, stomach discomfort, or cold sensations.
  • Hypoglycemia: Janumet, particularly when used in combination with certain other diabetes medications like insulin or sulfonylureas, can cause low blood sugar levels (hypoglycemia). Be aware of the signs and symptoms of hypoglycemia, such as shakiness, dizziness, sweating, confusion, and fast heartbeat. Follow your doctor’s instructions on how to manage and prevent hypoglycemia.
  • Surgery or medical procedures: If you are scheduled for surgery or any medical procedure, inform the healthcare professionals involved that you are taking Janumet. Your doctor may advise temporarily discontinuing the medication to reduce the risk of complications.
  • Pregnancy and breastfeeding: Janumet should only be used during pregnancy or breastfeeding if clearly needed and under the supervision of a healthcare professional. It is important to discuss the potential risks and benefits with your doctor.

These are general precautions, and it is essential to consult your healthcare provider for personalized advice based on your specific medical condition and circumstances. They will provide you with the most appropriate guidance regarding the use of Janumet and any necessary precautions.

What special dietary instructions should I follow?
