Key takeaways
Toujeo (insulin glargine) and Novolin N (insulin NPH) are both insulins used to manage diabetes, but they have some key differences. Toujeo is a long-acting insulin that lasts up to 36 hours and is typically injected once a day. It's available only by prescription and comes in prefilled pens. On the other hand, Novolin N is an intermediate-acting insulin that lasts up to 24 hours and can be injected once or twice a day. Novolin N can be purchased over the counter without a prescription and is available in both vials and prefilled pens. While Toujeo is more concentrated and better suited for those needing high doses of insulin, Novolin N can be mixed with regular insulin in the same syringe. Both medications can cause low blood sugar and weight gain, but they differ in their onset and duration of action.
