Lantus vs Insulin Glargine: are they the same?
Lantus is a commercial brand whose active ingredient is exactly Insulin Glargine. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Lantus contains Insulin Glargine as its active ingredient. Talking about "Lantus" in clinical terms is the same as talking about Insulin Glargine at the dose strengths 100 IU/mL. The differences from the authorised generic are brand, manufacturer (Sanofi), excipients, tablet appearance and price — not the active molecule itself.
When Lantus is used
Das Arzneimittel ist bei Erwachsenen und pädiatrischen Patienten mit Diabetes mellitus Typ 1 sowie bei Erwachsenen mit Diabetes mellitus Typ 2 indiziert, wenn ein Basalinsulin erforderlich ist.

Brand or generic — which to choose?
For most patients, authorised generics of Insulin Glargine are clinically equivalent substitutes for Lantus and typically cost substantially less. The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
