Jentadueto Side Effects Center

Medical Editor: Charles Patrick Davis, MD, PhD

Jenadueto (linagliptin and metformin hydrochloride) is a combination of two drugs indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus when treatment with both linagliptin and metformin is appropriate. Jenadueto is not available as a generic drug. Common side effects of Jentadueto are pancreatitis, nasopharyngitis, diarrhea, and hypoglycemia.

Jenadueto is available in the following strengths: tablets containing 2.5 mg linagliptin and 500 mg metformin hydrochloride or 850 mg metformin hydrochloride or 1000 mg metformin hydrochloride. The maximum recommended dose is 2.5 mg linagliptin/1000 mg metformin twice daily. Jenadueto should be taken daily with meals, with gradual dose escalation to reduce the gastrointestinal side effects due to metformin. Cationic drugs eliminated by renal tubular secretion may reduce metformin elimination. Serious side effects include lactic acidosis, hypoglycemia and impaired hepatic function. Women should alert their doctors if they are pregnant or planning to become pregnant. It is not known if Jentadueto will harm an unborn baby. Pregnant women should talk with their doctors about the best way to control blood sugar while pregnant. Women should also talk with their doctors if they are breastfeeding or plan to breastfeed. It is not known if Jentadueto passes into breast milk. Breastfeeding women should talk with their doctors about the best way to feed their babies while taking Jenadueto. Safety and effectiveness has not been established in the pediatric population.

Jentadueto FDA Prescribing Information: Side Effects
(Adverse Reactions)


Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.


The safety of concomitantly administered linagliptin (daily dose 5 mg) and metformin (mean daily dose of approximately 1800 mg) has been evaluated in 2816 patients with type 2 diabetes mellitus treated for ≥ 12 weeks in clinical trials.

Three placebo-controlled studies with linagliptin + metformin were conducted: 2 studies were 24 weeks in duration, 1 study was 12 weeks in duration. In the 3 placebo-controlled clinical studies, adverse events which occurred in ≥ 5% of patients receiving linagliptin + metformin (n=875) and were more common than in patients given placebo + metformin (n=539) included nasopharyngitis (5.7% vs 4.3%).

In a 24-week factorial design study, adverse events reported in ≥ 5% of patients receiving linagliptin + metformin and were more common than in patients given placebo are shown in Table 1.

Table 1 : Adverse Reactions Reported in ≥ 5% of Patients Treated with Linagliptin + Metformin and Greater than with Placebo in a 24-week Factorial-Design Study

Linagliptin Monotherapy
Metformin Monotherapy
Combination of Linagliptin with Metformin
  n (%) n (%) n (%) n (%)
Nasopharyngitis 1 (1.4) 8 (5.6) 8 (2.7) 18 (6.3)
Diarrhea 2 (2.8) 5 (3.5) 11 (3.8) 18 (6.3)

Other adverse reactions reported in clinical studies with treatment of linagliptin + metformin were hypersensitivity (e.g., urticaria, angioedema, or bronchial hyperactivity), cough, decreased appetite, nausea, vomiting, pruritus, and pancreatitis.

Linagliptin Monotherapy

Nasopharyngitis was reported in ≥ 5% of patients treated with linagliptin and more commonly than in patients treated with placebo (5.8% vs 5.5%). In the clinical trial program, pancreatitis was reported in 8 of 4687 patients (4311 patient-years of exposure) while being treated with TRADJENTA compared with 0 of 1183 patients (433 patient-years of exposure) treated with placebo. Three additional cases of pancreatitis were reported following the last administered dose of linagliptin.

Other adverse reactions reported in clinical studies with treatment of linagliptin monotherapy were hypersensitivity (e.g., urticaria, angioedema, localized skin exfoliation, or bronchial hyperactivity) and myalgia.

Metformin Monotherapy

The most common adverse reactions due to initiation of metformin are diarrhea, nausea/vomiting, flatulence, asthenia, indigestion, abdominal discomfort, and headache.

Long-term treatment with metformin has been associated with a decrease in vitamin B12 absorption which may very rarely result in clinically significant vitamin B12 deficiency (e.g., megaloblastic anemia) [see WARNINGS AND PRECAUTIONS].


In a 24-week factorial design study, hypoglycemia was reported in 4 (1.4%) of 286 subjects treated with linagliptin + metformin, 6 (2.1%) of 291 subjects treated with metformin, and 1 (1.4%) of 72 subjects treated with placebo. When linagliptin was administered in combination with metformin and a sulfonylurea, 181 (22.9%) of 792 patients reported hypoglycemia compared with 39 (14.8%) of 263 patients administered placebo in combination with metformin and sulfonylurea.

Laboratory Tests

Changes in laboratory findings were similar in patients treated with linagliptin + metformin compared to patients treated with placebo + metformin. Changes in laboratory values that occurred more frequently in the linagliptin + metformin group and ≥ 1% more than in the placebo group were not detected.

No clinically meaningful changes in vital signs were observed in patients treated with linagliptin.

Postmarketing Experience

Additional adverse reactions have been identified during postapproval use of linagliptin. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
