Can i switch from novolog and lantis to the relion brand of insulin?

ReliOn Insulin: Walmart sells ReliOn insulin, Novolin (Regular, NPH and 70/30) at discounted prices. These are biosynthetic human insulins, time to peak and duration of action do not replicate endogenous basal and postprandial insulin secretion. Synthetic insulin analogs (lispro, aspart, glulisine, glargine, detemir, degludec) are preferred. Discuss with your doctor if switching insulin is right for you.
