Healthcare professionals often prescribe Januvia for people with type 2 diabetes. It works by inhibiting the dipeptidyl peptidase-4 (DPP-4) enzyme, increasing insulin production, and decreasing glucagon production, which helps improve blood sugar management.
Januvia is generally well-tolerated but may cause mild side effects like upper respiratory tract infections and an upset stomach. Serious side effects are rare but can include pancreatitis and acute kidney failure.
Januvia can effectively lower blood sugar levels within a few days or weeks, and you can take it alongside other medications under the guidance of a healthcare team.
How does Januvia work for type 2 diabetes?
Januvia works by blocking the activity of the DPP-4 enzyme. This enzyme breaks down incretin hormones in the body, like glucagon-like peptide-1 (GLP-1) and gastric inhibitory peptide (GIP), which help regulate blood sugar levels.
By blocking DPP-4, Januvia increases the levels of GLP-1 and GIP, leading to increased insulin secretion and decreased glucagon secretion. This results in reduced blood sugar levels after meals and fasting in people with type 2 diabetes.
About its efficacy and potential side effects
Experts have demonstrated that Januvia can effectively lower blood sugar levels in people with type 2 diabetes. A 2016 study showed that it can significantly reduce hemoglobin A1c (HbA1c), which is your blood sugar levels over the past 2–3 months, and fasting blood sugar levels.
You take Januvia once each day before or after a meal. Although it acts quickly, it can take a few days to a few weeks to observe its full blood sugar-lowering effects. According to some studies, some people taking Januvia noticed improvements in their blood sugar levels after 18 weeks.
People generally tolerate Januvia well. However, like any medication, it may cause some side effects. The most commonly reported side effects of Januvia include:
- headaches
- upper respiratory tract infection, like the common cold
- arthralgia (joint pain)
- urinary tract infection
These side effects are mild and usually resolve on their own within a few days or weeks.
More serious side effects of Januvia are rare but can include:
- pancreatitis (inflammation of the pancreas)
- allergic reactions
- acute kidney failure
While these cases are rare, consider discussing your medical history and any existing kidney conditions with a healthcare professional before starting Januvia treatment. They will closely monitor how you respond to it and ensure its safety and efficacy.
However, seek immediate medical attention if you experience:
- severe stomach pain
- persistent nausea or vomiting
- rash
- itching
- swelling
These symptoms can be signs of a more serious condition, such as pancreatitis or an allergic reaction.
Does it work alongside any other medications?
You can take Januvia alone or in combination with other medications for treating type 2 diabetes. Healthcare professionals often prescribe it alongside other oral antidiabetic drugs like metformin or sulfonylureas.
Combining Januvia with other medications can help you achieve better blood sugar management by targeting the different processes involved in regulating glucose. A healthcare professional will determine the most appropriate combination of medications based on your needs and individual factors.
Consider discussing all of your medications, including over-the-counter drugs and supplements, with a healthcare team. They will review your medication list to ensure there are no potential interactions or adverse effects.
Are there any dietary adaptations to follow?
While taking Januvia, there is no need for any specific dietary adaptations. However, it’s important to maintain a balanced diet to help maintain stable blood sugar levels and manage type 2 diabetes effectively.
A healthy diet for people with diabetes typically includes:
- a variety of fruits
- nonstarchy vegetables
- whole grains
- lean proteins
- healthy fats
To keep your blood sugar levels within optimal range, medical professionals recommend limiting:
- sweetened beverages
- processed foods
- sugary foods
- desserts
While taking Januvia, it is important to avoid excessive alcohol consumption, as it can increase the risk of pancreatitis and hypoglycemia (low blood sugar).
Consider speaking with a healthcare team if you have any concerns or questions about dietary changes while taking Januvia. They can guide you based on your health needs and goals.
What are some alternative medications?
Sometimes, a doctor or healthcare professional may consider alternative medications depending on several factors, like your medical history, potential side effects, and treatment goals.
Some alternatives to Januvia include:
DPP-4 inhibitors
Alternative DPP-4 inhibitors include:
- saxagliptin (Onglyza)
- linagliptin (Tradjenta)
- alogliptin (Nesina)
Sulfonylureas
Sulfonylureas stimulate cells in the pancreas, called beta cells, to increase insulin production and reduce the amount of insulin cleared from the body by the liver. This helps lower blood sugar levels.
They include:
- glipizide ER (Glucotrol XL)
- glimepiride (Amaryl)
- glyburide (Glynase)
Sulfonylureas effectively lower blood sugar levels but can cause low blood sugar as a possible side effect.
Biguanides
These medications help reduce the amount of glucose the liver produces and improve insulin sensitivity. Commonly prescribed biguanides include:
- metformin
- metformin extended release (Fortamet, Glumetza)
- metformin glyburide
Metformin is the preferred first-line medication for treating type 2 diabetes due to its effectiveness and low risk of hypoglycemia.
Glucagon-like peptide-1 (GLP-1) receptor agonists
These medications mimic the action of incretin hormones, stimulating insulin secretion and suppressing glucagon release. This leads to lower blood sugar levels. They include:
You can discuss alternative options with a healthcare professional to help determine the appropriate medication for you.
