Insulin

Question from Fort Myers, Florida, USA:
Does insulin have to be refrigerated? Is there a difference in strength Novo and Lilly NPH and Regular?
Answer:
From: DTeam Staff
All insulins would last longer if refrigerated, but, in reasonable temperate climates/temperatures, insulin can last at room temperatures for about a month. We suggest changing bottles after end of month.
Nobody has done direct comparisons between Lilly and Novo insulins but they are rather similar. We generally do not suggest changing from one to the other unless there are specific allergies suspected.
