Boxed warning

LACTIC ACIDOSIS.

Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. The onset of metformin-associated lactic acidosis is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Metformin-associated lactic acidosis was characterized by elevated blood lactate levels (>5 mmol/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), an increased lactate/pyruvate ratio; and metformin plasma levels generally >5 mcg/mL [see Warnings and Precautions (5.1) ]. Risk factors for metformin-associated lactic acidosis include renal impairment, concomitant use of certain drugs (e.g., carbonic anhydrase inhibitors such as topiramate), age 65 years old or greater, having a radiological study with contrast, surgery and other procedures, hypoxic states (e.g., acute congestive heart failure), excessive alcohol intake, hepatic impairment, and mitochondrial diseases [see Warnings and Precautions (5.1) ]. Steps to reduce the risk of and manage metformin-associated lactic acidosis in these high risk groups are provided in the full prescribing information [see Dosage and Administration (2.2), Contraindications (4), Warnings and Precautions (5.1), Drug Interactions (7), and Use in Specific Populations (8.6 , 8.7) ].

What does the patient leaflet for linagliptin and metformin say first?

The FDA-approved Medication Guide or Patient Information that comes with the medicine, in its own words.

From the patient leaflet: What is the most important information I should know about JENTADUETO?

JENTADUETO can cause serious side effects, including: 1. Lactic acidosis. Metformin hydrochloride (HCl), one of the medicines in JENTADUETO, can cause a rare but serious condition called lactic acidosis (a build-up of lactic acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in a hospital. Stop taking JENTADUETO and call your healthcare provider right away or go to the nearest hospital emergency room if you get any of the following symptoms of lactic acidosis: feel very weak and tired have unusual (not normal) muscle pain have trouble breathing have unexplained stomach or intestinal problems with nausea and vomiting, or diarrhea have unusual sleepiness or sleep longer than usual feel cold, especially in your arms and legs feel dizzy or lightheaded have a slow or irregular heartbeat You have a higher chance of getting lactic acidosis with JENTADUETO if you: have severe kidney problems. have liver problems. drink a lot of alcohol (very often or short-term "binge" drinking). get dehydrated (lose a large amount of body fluids). This can happen if you are sick with a fever, vomiting, or diarrhea. […]

From the patient leaflet: What should I avoid while taking JENTADUETO?

Avoid drinking alcohol very often or drinking a lot of alcohol in a short period of time ("binge" drinking). It can increase your chances of getting serious side effects.

From the patient leaflet: How should I store JENTADUETO?

Store JENTADUETO at room temperature between 68°F and 77°F (20°C and 25°C). Keep tablets dry. Keep JENTADUETO and all medicines out of the reach of children.

Is there a generic for linagliptin and metformin (Jentadueto)?

The FDA approved the first generic linagliptin and metformin on August 30, 2021. 4 generic applications are approved; 4 of them carry a current (not discontinued) marketing status in Drugs@FDA; that status is not evidence that the generic is on sale. Drugs@FDA also holds 2 tentative approvals: the FDA found the generic approvable, but patents or exclusivity keep it from final approval for now.

FDA's NDC Directory lists linagliptin and metformin from 1 labeler under a generic (ANDA) application and from 1 brand labeler. A listing means the company has registered the product for sale; it does not show that every pharmacy stocks it. In the latest NADAC survey pharmacies bought only the brand, so a generic may not be on sale yet.

The Orange Book lists 10 patents for Jentadueto tablets, the last expiring on December 8, 2037. A patent or exclusivity date is not the date a generic goes on sale: court cases and settlements move it either way.

  • 2012 earliest approval on file
  • 2021 first generic approved
  • 2037 last listed patent

What does the linagliptin and metformin label say about other medicines?

The linagliptin and metformin label names 11 other medicines in its interaction, contraindication or warning sections. The sentences are the labels' own; a label lists what its studies and reports found, not every interaction.

Medicine namedSectionWhat the label says
Acetazolamidedrug interactionsClinical Impact; Topiramate or other carbonic anhydrase inhibitors (e.g., zonisamide, acetazolamide or dichlorphenamide) frequently cause a decrease in serum bicarbonate and induce non-anion gap, hyperchloremic metabolic acidosis. Concomitant use of these drugs with JENTADUETO may increase the risk of lactic acidosis.
Cimetidinedrug interactions… [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) could increase systemic exposure to metformin and may increase the risk for lactic acidosis [see ].

Phenytoindrug interactions… thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid.
Ranolazinedrug interactionsClinical Impact; Concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) could increase …
Rifampindrug interactionsClinical Impact; Rifampin decreased linagliptin exposure, suggesting that the efficacy of linagliptin may be reduced when administered in combination with a strong P-gp or CYP3A4 inducer.
