Refer to adult dosing; use with caution
Dosing: Renal Impairment
eGFR ≥15 mL/minute/1.73 m2 to <90 mL/minute/1.73 m2: There are no specific dosage adjustments provided in the manufacturer’s labeling for the combination product; insulin requirements may be reduced due to changes in insulin clearance or metabolism; monitor blood glucose closely. Limited data indicates lixisenatide exposure is increased in patients with severe impairment (eGFR <30 mL/minute/1.73 m2). Also refer to individual monographs.
eGFR <15 mL/minute/1.73 m2: Use is not recommended (has not been studied).
Dosing: Hepatic Impairment
There are no specific dosage adjustments provided in the manufacturer’s labeling for the combination product; insulin requirements may be reduced due to changes in insulin clearance or metabolism; monitor blood glucose closely. Also refer to individual monographs.
For SubQ use only. Do not administer IM, IV, or via an insulin pump. Cold injections should be avoided. Inject into the abdomen, thigh, or upper arm. Rotate injection sites for each dose; do not use the same site for each injection to avoid lipodystrophy. Administer within one hour before the first meal of the day, preferably the same meal each day. If a dose is missed, resume with the next scheduled dose. Do not double dose or increase the dose to make up for the missed dose. Solution should appear clear and colorless; do not use if particulate matter or coloration is seen. Do not split the dose. Do not mix or dilute with any other insulin or solution.
Individualized medical nutrition therapy (MNT) based on ADA recommendations is an integral part of therapy (ADA 2016b).

Concerns related to adverse effects:
• Antibody formation: Development of antibodies to insulin and lixisenatide may occur; in clinical trials with lixisenatide, high titers were observed in 2.4% of patients and were associated with an attenuated glycemic response. Allergic reactions and injection site reactions were more frequent in antibody positive patients; consider alternative antidiabetic therapy in patients not achieving targeted glycemic control or with worsening glycemic control and/or significant allergic or injection site reactions.
• Hypersensitivity: Serious hypersensitivity reactions including anaphylaxis and angioedema have been reported with lixisenatide and with insulin glargine; discontinue use if hypersensitivity reactions occur and treat promptly as indicated. It is not known if patients with a history of hypersensitivity to other GLP-1 agonists are at increased risk for hypersensitivity reactions with lixisenatide; patients with prior serious reactions to similar agents should be monitored closely.
• Hypoglycemia: The most common adverse effect of insulin is hypoglycemia. The timing of hypoglycemia differs among various insulin formulations. Hypoglycemia may result from increased work or exercise without eating; use of long-acting insulin preparations (eg, insulin detemir, insulin glargine, insulin degludec) may delay recovery from hypoglycemia. Profound and prolonged episodes of hypoglycemia may result in convulsions, unconsciousness, temporary or permanent brain damage, or even death. Insulin requirements may be altered during illness, emotional disturbances, or other stressors. Instruct patients to use caution with ethanol; may increase risk of hypoglycemia.
• Hypokalemia: Insulin (especially IV insulin) causes a shift of potassium from the extracellular space to the intracellular space, possibly producing hypokalemia. If left untreated, hypokalemia may result in respiratory paralysis, ventricular arrhythmia and even death. Use with caution in patients at risk for hypokalemia (eg, loop diuretic use). Monitor serum potassium and supplement potassium when necessary.
• Pancreatitis: Cases of acute pancreatitis (including hemorrhagic and necrotizing with some fatalities) have been reported with GLP-1 receptor agonists; monitor for signs and symptoms of pancreatitis (eg, persistent severe abdominal pain which may radiate to the back, and which may or may not be accompanied by vomiting). If pancreatitis is suspected, discontinue use. Do not resume unless an alternative etiology of pancreatitis is confirmed. Consider alternative antidiabetic therapy in patients with a history of pancreatitis (has not been studied).
• Gastroparesis: Lixisenatide slows gastric emptying and is not recommended for use in patients with gastroparesis (has not been studied); do not initiate therapy in patients with severe gastroparesis.
• Renal impairment: Use with caution in patients with renal impairment. Dosage adjustments may be necessary. Patients with mild to moderate renal impairment (eGFR ≥30 to 89 mL/minute/1.73 m2) may be at increased risk of adverse effects (eg, diarrhea, nausea, vomiting) which may lead to dehydration, acute kidney injury, and worsening of chronic renal failure. There is limited experience with severe impairment (eGFR 15 to <30 mL/minute/1.73 m2); lixisenatide exposure may be increased in these patients. Monitor all patients with renal impairment closely for decreasing renal function. Use is not recommended in patients with end-stage renal disease (eGFR <15 mL/minute/1.73 m2) (has not been studied).
• Hepatic impairment: Use with caution in patients with hepatic impairment. Dosage adjustments may be necessary.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
Dosage form specific issues:
• Multiple dose injection pens: According to the Centers for Disease Control and Prevention (CDC), pen-shaped injection devices should never be used for more than one person (even when the needle is changed) because of the risk of infection. The injection device should be clearly labeled with individual patient information to ensure that the correct pen is used (CDC 2012).
• Appropriate use: Not approved for use in patients with diabetic ketoacidosis (DKA) or patients with type 1 diabetes mellitus (insulin-dependent, IDDM).
• Patient education: Diabetes self-management education (DSME) is essential to maximize the effectiveness of therapy.
Diabetes mellitus: Plasma glucose, electrolytes, HbA1c (at least twice yearly in patients who have stable glycemic control and are meeting treatment goals; quarterly in patients not meeting treatment goals or with therapy change [ADA 2016a]), potassium (in patients at risk for hypokalemia; renal function, signs/symptoms of pancreatitis; signs/symptoms of adverse GI effects (diarrhea, nausea, vomiting); signs/symptoms of hypersensitivity
Adverse events were observed in some animal reproduction studies. Refer to individual monographs.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience nausea, vomiting, diarrhea, constipation, abdominal pain, flatulence, lack of appetite, rhinitis, pharyngitis, common cold symptoms, headache, weight gain, or injection site irritation. Have patient report immediately to prescriber signs of pancreatitis (severe abdominal pain, severe back pain, severe nausea, or vomiting), signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), signs of low potassium (muscle pain or weakness, muscle cramps, or an abnormal heartbeat), difficulty swallowing, vision changes, dizziness, passing out, seizures, change in skin to thick or thin at injection site, shortness of breath, excessive weight gain, swelling in the arms or legs, or signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, tachycardia, confusion, increased hunger, or sweating) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
