Insulin glargine (Lantus)

ATI class: Long-acting insulin / Antidiabetic

Action

  • ATI/source-folder candidate for Insulin glargine (Lantus); verify mechanism against the source table before validation.

Therapeutic use

  • Review under Diabetes mellitus medication safety.

Nursing assessment

  • Review fasting glucose trends.
  • Assess for nocturnal or fasting hypoglycemia.
  • Confirm the ordered basal insulin schedule.

Administration

  • Verify route against the order and source table.

Side effects

  • Verify common side effects against the source table.

Adverse effects

  • Hypoglycemia
  • Weight gain
  • Injection-site reactions

Interactions

  • Beta blockers may mask hypoglycemia.
  • Corticosteroids can increase insulin requirements.
  • Alcohol can increase hypoglycemia risk.

Contraindications

  • Current hypoglycemia

Precautions

  • Do not mix glargine with other insulins in the same syringe.
  • Use caution when appetite, renal function, or activity level changes.

Client teaching

  • Take at the same time each day as prescribed.
  • Do not use basal insulin as a rapid correction dose.
  • Rotate injection sites and keep glucose records.

Medication outcomes

  • Therapeutic response with no priority adverse effects.

Antidote / rescue

  • No specific antidote is seeded; hold/question unsafe doses and manage toxicity per provider, facility, or poison-control guidance.

NCLEX priority cues

  • Basal insulin can still cause hypoglycemia even without a meal-time peak.
  • Confusing basal and rapid-acting insulin is a medication-safety priority.
  • Unexpected nighttime sweating or morning headache can suggest overnight hypoglycemia.
