Why would a prescriber prefer Lantus over Levemir or vice versa? I know that they are both long-acting insulins. I remember asking a pharmacist about it awhile ago and the only answer they provided me was that Levemir is cheaper than Lantus.
The reason I ask is because I had a patient who was on Lantus 15 units at bedtime. The MD ended up lowering the dose and changing the order to Levemir 10 units at bedtime when I came back the next night. The lowered dosage makes sense, but why change from Lantus to Levemir?
