What is NovoLog and how does it work?
NovoLog is a brand name for insulin aspart, a rapid-acting (mealtime, or "bolus") human insulin analog. It is FDA-approved to improve blood sugar control in adults and children with type 1 or type 2 diabetes. NovoLog is injected under the skin shortly before meals to handle the rise in blood sugar that comes from eating, and it can also be used in external insulin pumps or, in hospital settings, given by IV infusion under supervision.
Because it is a fast, short-acting insulin, NovoLog is typically used together with a longer-acting basal insulin (such as Lantus, Levemir, or Tresiba) that covers your baseline needs between meals and overnight. NovoLog comes in vials and in the prefilled NovoLog FlexPen, and there is also a premixed option, NovoLog Mix 70/30. Fiasp is a faster-acting formulation of the same insulin aspart. Your provider decides which product and dose fit your treatment plan.
NovoLog cost: manufacturer savings card vs. the Rx.com cash coupon
Novo Nordisk, the maker of NovoLog, runs an official manufacturer savings card program through its NovoCare site. Manufacturer copay cards like this are generally limited to people with commercial (private) insurance and are not available if you have Medicare, Medicaid, or other government coverage, and the terms and eligibility can vary. If you are uninsured, on Medicare, or your savings card is declined at the pharmacy, the manufacturer card may not help you.
That is where the Rx.com cash coupon comes in. It is a straightforward discount you can use whether or not you have insurance, including when a manufacturer card will not apply. Novo Nordisk also offers a patient assistance program for those who qualify based on income, which is worth asking about if cost is a barrier. The biggest savings lever, though, is often the generic: a generic insulin aspart is available and is the same medicine at a lower price. Enter your ZIP above to compare today's cash price on both NovoLog and generic insulin aspart at pharmacies near you.
NovoLog alternatives and how it compares
NovoLog is one of several rapid-acting mealtime insulins. The closest comparison is Humalog (insulin lispro); both are fast-acting insulins taken before meals and work in a very similar way, though they are different molecules and your provider may prefer one based on your response, your pump, or your coverage. Fiasp is a faster-acting version of the same insulin aspart found in NovoLog.
For a generic option, insulin aspart is the generic form of NovoLog itself. Keep in mind that mealtime insulins like these are different from the long-acting basal insulins used for background coverage, such as Lantus, Levemir, and Tresiba - many people use one of each. Never switch insulins, brands, or doses on your own; changes should be made with your provider.
Safety and side effects to know
The most common and potentially serious side effect of NovoLog is hypoglycemia (low blood sugar), which can be life-threatening. Your risk goes up with changes in meals, physical activity, or other diabetes medicines, so learn the warning signs (shakiness, sweating, confusion) and how to treat a low. NovoLog can also lower potassium (hypokalemia), and serious allergic reactions, though rare, are possible. Do not use NovoLog if the solution is cloudy or discolored (except for the premixed 70/30), and do not dilute or mix it in a pump. If you also take a thiazolidinedione (TZD) diabetes medicine, watch for fluid retention and signs of heart failure. NovoLog has no FDA boxed warning.
An important safety rule: never share pens, cartridges, or needles between people, even if the needle is changed, because of the risk of passing bloodborne infections. This information is educational and is not medical advice. Talk with your doctor or pharmacist about your specific situation, dosing, and how to store and use your insulin correctly.
