Lantus Warnings and Precautions, Diabetes Library

Lantus Warnings and Precautions: Lantus is prescribed to diabetics to control blood sugar; do not use if you are allergic to any of its ingredients. Make sure the prescribing physician knows if you have liver disease, kidney disease, or any allergies. Like other insulin, many medications can interact with Lantus and alter how effective it will be. Discuss your current medications with your prescribing physician. Monitoring blood sugar levels is an important part of a diabetic treatment program; many health insurance plans will cover the cost of a glucose monitor.
