Epidra and lantus are 2 different types of insulins. Epidra is a short acting, pre-meal bolus insulin and Lantus is a basal insulin or long acting insulin. Epidra has to be given only when the patient eats. Lantus, on the other hand, can be given once or twice daily at the same time every day without regard to meals. Both insulin products can be prescribed to the same patient. Lantus will cover a person's blood sugar before meals, and Epidra will cover a person's blood sugar after meals.
