Unlike other insulin analogues, Lantus is a long-acting insulin form, which allows injecting the prescribed Lantus dose only once a day.

Lantus insulin is released with no pronounced peak for the period of 24 hours, thus you don’t need to balance a peak at a specific time.

The results of clinical trials in several countries showed increase of cancer diseases rates in patients receiving Lantus insulin. Nevertheless, the final proofs have not been found yet, that is why patients using Lantus pens are recommended to continue this treatment.
