From the FDA label for Rezvoglar (application BLA761215). Other insulin glargine-aglr products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.

Individualize dosage based on metabolic needs, blood glucose monitoring, glycemic control, type of diabetes, and prior insulin use. ( 2.1 , 2.2 , 2.3 , 2.4 ) Administer subcutaneously into the abdominal area, thigh, or deltoid once daily at any time of day, but at the same time every day. ( 2.1 ) Do not dilute or mix with any other insulin or solution. ( 2.1 ) Rotate injection sites to reduce the risk of lipodystrophy and localized cutaneous amyloidosis. ( 2.1 ) See Full Prescribing Information for the recommended starting dosage in patients with type 2 diabetes and how to change to REZVOGLAR from other insulins ( 2.3 , 2.4 ) Closely monitor glucose when switching to REZVOGLAR and during initial weeks thereafter. ( 2.4 ) 2.1 Important Administration Instructions Always check insulin labels before administration [see Warnings and Precautions ( 5.4 )] . Visually inspect REZVOGLAR KwikPen prefilled pens for particulate matter and discoloration prior to administration. Only use if the solution is clear and colorless with no visible particles. Administer REZVOGLAR subcutaneously into the abdominal area, thigh, or deltoid, and rotate injection sites within the same region from one injection to the next to reduce the risk of lipodystrophy and localized cutaneous amyloidosis. Do not inject into areas of lipodystrophy or localized cutaneous amyloidosis [see Warnings and Precautions (…

Hypersensitivity Reactions [see Warnings and Precautions ( 5.5 )] . Hypokalemia [see Warnings and Precautions ( 5.6 )] . Adverse reactions commonly associated with insulin glargine products include hypoglycemia, allergic reactions, injection site reactions, lipodystrophy, pruritus, rash, edema, and weight gain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trial of another drug and may not reflect the rates observed in practice. The data in Table 1 reflect the exposure of 2327 patients with type 1 diabetes to insulin glargine or NPH in Studies A, B, C, and D [see Clinical Studies ( 14.2 )] . The type 1 diabetes population had the following characteristics: Mean age was 39 years. Fifty-four percent were male, 97% were Caucasian, 2% were Black or African American and 3% were Hispanic. The mean BMI was 25.1 kg/m 2 . The data in Table 2 reflect the exposure of 1563…

Insulin Glargine-Aglr drug interactions

Table 8 includes clinically significant drug interactions with REZVOGLAR. Table 8: Clinically Significant Drug Interactions with REZVOGLAR Drugs that May Increase the Risk of Hypoglycemia Drugs: Antidiabetic agents, ACE inhibitors, angiotensin II receptor blocking agents, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, salicylates, somatostatin analogs (e.g., octreotide), sulfonamide antibiotics. GLP-1 receptor agonists, DPP-4 inhibitors, and SGLT-2 inhibitors. Intervention: Dosage reductions and increased frequency of glucose monitoring may be required when REZVOGLAR is coadministered with these drugs. Drugs that May Decrease the Blood Glucose Lowering Effect of REZVOGLAR Drugs: Atypical antipsychotics (e.g., olanzapine and clozapine), corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens (e.g., in oral contraceptives), protease inhibitors, somatropin, sympathomimetic agents (e.g., albuterol, epinephrine, terbutaline), and thyroid hormones. Intervention: Dosage increases and increased frequency of glucose monitoring may be required when REZVOGLAR is coadministered with these drugs. Drugs that May Increase or Decrease the Blood Glucose Lowering Effect of REZVOGLAR Drugs: Alcohol, beta-blockers, clonidine, and lithium salts. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Intervention: Dose adjustment and increased frequency of glucose monitoring may be required when REZVOGLAR is coadministered with these drugs. Drugs that May Blunt Signs and Symptoms of Hypoglycemia Drugs: Beta-blockers, clonidine, guanethidine, and reserpine. Intervention: Increased frequency of glucose monitoring may be required when REZVOGLAR is coadministered with these drugs. Drugs that affect glucose metabolism: Adjustment of insulin dosage may be needed. ( 7 ) Antiadrenergic Drugs (e.g., beta-blockers, clonidine, guanethidine, and reserpine): Signs and symptoms of hypoglycemia may be reduced or absent. ( 5.3 , 7 )

What people report to the FDA about insulin glargine-aglr

The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 6 reports naming insulin glargine-aglr, and the FDA flagged 50% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:

  • adverse event1 reports
  • asthma1 reports
  • blood creatinine increased1 reports
  • blood potassium increased1 reports
  • encephalopathy1 reports
  • glomerular filtration rate decreased1 reports
  • herpes zoster disseminated1 reports
  • impaired quality of life1 reports

Read these as a signal, not a rate. A report does not mean insulin glargine-aglr caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.
