Oral medications and diet alone are typically insufficient when LADA and sugar levels are this high, and insulin is frequently needed early. If you haven't already, you should see an endocrinologist right away to begin or modify an appropriate insulin regimen and to have your HbA1c, C-peptide, and antibodies checked. Treatment should not be postponed since persistently elevated blood sugar levels might exacerbate beta-cell loss and quickly lead to problems.

Indeed, insulin glargine is included in both Lantus 100 IU and Glaritus 100 IU, and they can be used interchangeably. Blood sugar should be continuously checked after switching, though, as individual sensitivity and absorption can differ slightly. Always wait to make a modification until your doctor has confirmed the dosage and timing.
