How Jentadueto (linagliptin / metformin) works
Jentadueto (linagliptin / metformin) is a combination of two medications.
- Linagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor. It works by blocking DPP-4, a protein that breaks down certain hormones in your body. These hormones normally tell your body to make more insulin and produce less sugar. When DPP-4 causes these hormone levels to drop, you end up having high blood sugar levels. By blocking the action of DPP-4, linagliptin helps your body produce more insulin and make less sugar. In doing so, linagliptin helps lower your blood sugar levels.
- Metformin is a biguanide that lowers blood sugar in several ways. It lowers the amount of sugar that your liver makes. It also makes your body more sensitive to the effects of insulin. When your body is able to use insulin better, it can move more blood sugar into your cells to use as energy. In addition, metformin lowers the amount of sugar that gets absorbed through your intestines. As a result of these three pathways, metformin helps lower the amount of sugar in your bloodstream.

Pharmacist tips for Jentadueto (linagliptin / metformin)
- Take Jentadueto (linagliptin / metformin) with food. The metformin in this medication can cause stomach problems, including diarrhea, nausea, vomiting, and belly pain. So food can help lower the risk of these side effects.
- While you're taking Jentadueto (linagliptin / metformin), make sure to drink enough fluids to keep hydrated, especially if you're experiencing vomiting or diarrhea or feeling ill. These conditions can lead to dehydration and raise your risk of having a buildup of lactic acid in your blood.
- If you're scheduled for a surgery, let your primary care provider know ahead of time. They can discuss with you when to stop Jentadueto (linagliptin / metformin) before surgery and when to restart this medication afterwards. This is because you might not be able to eat or drink during the time around your surgery, which can raise your risk of lactic acidosis.
- Talk with a provider or radiologist about your medication history before getting any procedures done. The contrast dyes that are used for certain imaging procedures can temporarily affect your kidneys. If you're taking Jentadueto (linagliptin / metformin), this effect on the kidneys can raise your risk of metformin buildup in your body and lactic acidosis, which can be dangerous. Don't restart this medication until your provider checks your kidney health to make sure it's safe for you to do so.
- If you feel cold in your hands or feet, dizzy, weak, confused, or nauseous or have trouble breathing, belly pain, or a racing heart, stop taking Jentadueto (linagliptin / metformin) and get medical attention right away. These can be signs of a serious condition called lactic acidosis (high acid levels in the blood), which sometimes can require treatment in the hospital.
- Jentadueto (linagliptin / metformin) can interact with certain medications. For example, ranolazine (Ranexa), a medication used to treat chest pain, can expose your body to more metformin, which raise your risk of lactic acidosis. Let your provider or pharmacist know what medications you're taking, including over-the-counter products and supplements, before you start Jentadueto (linagliptin / metformin).
- Make sure to get your routine blood tests done on time while you’re taking Jentadueto (linagliptin / metformin). By doing so, your provider can check for side effects, like liver injury or changes to your vitamin B12 levels, or your risk for lactic acidosis (too much acid in your blood). This makes sure Jentadueto (linagliptin / metformin) is safe for you to take.
- It's important to eat healthy and exercise regularly to keep your blood sugar under control. Make sure to work with your provider on a diet and exercise plan while taking Jentadueto (linagliptin / metformin).
