The data in Table 1 reflect the exposure of 2,327 patients with type 1 diabetes to insulin glargine or NPH in Studies A, B, C, and D [see Clinical Studies (14.2) ] .

Intervention: Dosage increases and increased frequency of glucose monitoring may be required when Insulin Glargine-yfgn is coadministered with these drugs. Drugs that May Increase or Decrease the Blood Glucose Lowering Effect of Insulin Glargine-yfgn Drugs: Alcohol, beta-blockers, clonidine, and lithium salts. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Intervention: Dosage adjustment and increased frequency of glucose monitoring may be required when Insulin Glargine-yfgn 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 Insulin Glargine-yfgn 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. ( 7 ) * Biosimilar means that the biological product is approved based on data demonstrating that it is highly similar to an FDA-approved biological product, known as a reference product, and that there are no clinically meaningful differences between the biosimilar product and the reference product. Biosimilarity of Insulin Glargine-yfgn has been demonstrated for the condition(s) of use (e.g., indication(s), dosing regimen(s)), strength(s), dosage form(s), and route(s) of administration described in its Full Prescribing Information.

How long insulin glargine-yfgn keeps

No insulin glargine-yfgn label we read sets a separate limit for after opening, but they do specify how it must be stored — and the stability behind any date assumes those conditions.

What people report to the FDA about insulin glargine-yfgn

The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 2,037 reports naming insulin glargine-yfgn, and the FDA flagged 11% 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:

  • device mechanical issue874 reports
  • device issue286 reports
  • device delivery system issue249 reports
  • device defective216 reports
  • product storage error214 reports
  • device breakage169 reports
  • blood glucose increased140 reports
  • wrong technique in device usage process96 reports

Read these as a signal, not a rate. A report does not mean insulin glargine-yfgn 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.
