Yes, you’d be able to make the switch if your doctor recommends that you change treatment from Lantus to Basaglar.
Lantus and Basaglar contain the same type of insulin: insulin glargine. The Food and Drug Administration (FDA) has determined that Basaglar is a “follow-on” insulin glargine to Lantus. This means that Basaglar is very similar to Lantus and that it’s just as safe and effective as Lantus.
Basaglar and Lantus are both available in the same strength: 100 units of insulin per mL of drug solution. If you switch from Lantus to Basaglar, your dosage will probably stay the same.
If you’re interested in switching from Lantus to Basaglar, talk with your doctor to see if that’s a good option for you.
