About NovoLog

NovoLog is considered insulin, which therefore functions by increasing insulin levels in the body. The insulin dose can help reduce high blood sugar in diabetes mellitus.

Like any insulin, this medication can only be used for type 1 and type 2 diabetes mellitus. It could worsen already low blood sugar (hypoglycemia) because its primary goal is to help the body remove and store blood sugar.

 

NovoLog is known to treat type 1 and type 2 diabetes mellitus. NovoLog is available only by prescription, and is available in a generic formulation called insulin aspart.

NovoLog may be prescribed as an injection. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage you are prescribed.

 

If you are prescribed NovoLog, follow the usage directions carefully, and continue using the medication if a healthcare provider tells you to. The medication has different forms, including the Flexpen Novolog flextouch penfill.

 

If you suddenly stop using insulin aspart, then you will experience problems with controlling high blood sugar. This is not an insulin pump, but instead comes in the form of NovoLog Flextouch penfill cartridge options, which makes it easier to administer the insulin dose at appropriate times.

 

Insulin aspart is a fast or rapid-acting insulin, starting to work in as little as 15 minutes and reaching peak effects in 1 hour. Novolog is usually part of a regimen of insulin that may include longer-acting forms to provide baseline coverage over 24 hours.

NovoLog uses

There is a single FDA-approved use for NovoLog, but it may also be used off-label to treat other conditions. Your online medical professional may prescribe it for the following reasons.

It’s also possible that your healthcare provider may prescribe it for other reasons not listed here. Ask your online doctor or pharmacist if you have questions about why a medication is prescribed.

Diabetes mellitus

If you have diabetes mellitus, you generally have difficulty controlling high blood sugar. Consistent high blood sugar can cause serious adverse effects. For example, failure to control high blood sugar can cause you to develop a severe infection.

NovoLog's active ingredient, insulin aspart, can help to provide you with the correct insulin dose to control high blood sugar and keep your glucose levels stable.

The medication releases quickly and can start having a glucose-lowering effect within 15 minutes after administration. To help manage low blood sugar in people with diabetes, it is generally advised to consume a meal shortly after using the medication.

NovoLog side effects

The side effects associated with taking NovoLog are typically mild to moderate. Most NovoLog side effects are associated with blood sugar control. This is why glucose monitoring is crucial while you use insulin aspart. NovoLog has some common side effects. They may include:

  • Weight gain

  • Skin rashes

  • Low potassium levels


There is also a low blood sugar risk (hypoglycemia) when using Novolog to treat diabetes. When you have low blood sugar, you may experience severe side effects. These adverse reactions associated with low blood sugar levels can sometimes lead to unconsciousness.

You should also be on the lookout for injection site reactions. If the individual fails to take note of injection site reactions, this can give people a severe infection.

Other side effects, which are less common but might be more severe, could include:

  • Severely low potassium: Potassium plays several roles in the body. If the insulin aspart causes low potassium levels that become severe, then the patient may experience more serious symptoms. This includes leg cramps, an irregular heartbeat, greater thirst, and a need to urinate more frequently. Numbness, tingling, and muscle weakness are also signs of low potassium levels.

  • Severe hypoglycemia: Low blood sugar is generally considered dangerous, but when using insulin aspart, levels may decline more significantly. This can cause excessive sweating, delirium, fainting, and seizures. Talk to your doctor to make sure you know how to manage low blood sugar levels. 

  • Heart-related complications: There have also been some rare cases where individuals experienced complications with their cardiovascular system while using insulin aspart. This may lead to unexpected and sudden weight gain, difficulty breathing, and swelling.


You should call your doctor if you notice any of these side effects or if you develop any other new or concerning symptoms, and should call 911 immediately if you have any severe symptoms.

Insulin aspart or NovoLog is sometimes used in children under 12 years, as long as the pediatric patient is at least two years of age.

How to take NovoLog

Your pharmacist will provide you with instructions on how to take your NovoLog prescription.

Be sure to read your prescription label and follow the instructions. Call your doctor or pharmacy if you have any questions.

NovoLog can come in different forms and doses, so follow the specific instructions on your prescription. Your healthcare provider tells you, in most cases, to use the drug a few minutes before you have a meal.

This is due to the fast-acting mechanism that NovoLog provides. If you fail to eat a meal within 10 minutes after administering insulin apart, you may experience a drop in blood sugar levels.

What to avoid while taking NovoLog

NovoLog has some serious drug interactions. Don’t change what you take without checking with your doctor or pharmacist. That includes other medications or supplements, as well as over-the-counter drugs. 

It is essential to be careful about taking insulin aspart of other insulin products unless under medical supervision. A high insulin dose, especially when both are fast acting, significantly increases your risk of severe hypoglycemia.

Tell your doctor about other medications that you take. This can help to avoid medication errors that could lead to drug interactions. Make sure you also mention any over-the-counter medicines that you use too.

Some medications may increase the risk of low blood sugar due to potential effects on blood sugar control.

You should also tell your doctor if you take specific heart medication. In some cases, these drugs may reduce the symptoms that come with a more significant blood glucose-lowering effect.

This makes it challenging to detect hypoglycemia before the condition becomes more severe. At this point, the patient may have trouble breathing and requires emergency medical help.

Do not avoid food when using an insulin aspart injection. This prescription medication is meant to be used about 10 minutes before you have a meal. You should also check your blood sugar regularly to ensure the medicine works properly.

Ask your doctor or pharmacist if it is acceptable to consume alcohol while taking NovoLog. Some research shows that regular alcohol consumption may interfere with the body's ability to normal blood glucose levels. Alcohol may also reduce the medication’s ability to do its job, making it harder to keep your blood glucose levels stable.

Medication alternatives to NovoLog

If your healthcare provider prefers to put you on another treatment, they may suggest another insulin or an antidiabetic medication in another drug class. Here are some common doctor-recommended alternatives based on your health issue:

Long-lasting treatment

NovoLog and an insulin aspart injection provide a fast-acting type of insulin. It works similarly to human insulin.

These prescription drugs do not offer blood sugar control over a more extended period of time but rather provide a more immediate effect. Some patients may require prescription drugs that work for longer. This is a case where the doctor may give long-acting insulin instead. These options include:
Lantus Toujeo Levemir Basaglar

NovoLog prescription FAQs

How much does NovoLog cost?

There are no fixed costs for insulin aspart injection options. You need to consider the type of insulin aspart that you will use. The insulin dose provided through the Novolog prescription medication also affects its overall cost.

How can I refill my NovoLog prescription?

NovoLog is only available by prescription, so you must see a board-certified doctor to get a refill on your medication. You can book a virtual appointment with one of our top-rated board-certified doctors to get started. After a qualifying evaluation, your prescription will be sent to your local pharmacy for pickup.

How long can NovoLog insulin be out of the fridge?

Once you use NovoLog for the first time, you can leave it at room temperature for an extended period of time. This is not an insulin pump and generally comes as an insulin aspart injection. In most cases, the prescription medication should remain usable for up to 28 days if you keep it under 86 degrees Fahrenheit.

How long does it take NovoLog to lower blood sugar

NovoLog acts quickly, so it usually takes around 15 minutes to start working. After you use the insulin aspart injection, you should consume a meal. This is because insulin aspart injection is considered a mealtime insulin option. 

Who should not take NovoLog?

Do not take an insulin aspart injection if you have low blood sugar. This is due to a blood glucose-lowering effect that the medication produces. You should also avoid NovoLog if you have existing heart conditions.

What happens if I miss a dose of NovoLog?

You should not take a double dose to make up for a missed dose. These doses are generally advised to be taken before a meal, so take them as soon as you remember. With this said, do not take NovoLog I you will not have a meal in a short span afterward.

What happens if I take too much NovoLog?

Too much insulin aspart in your system can lead to more significant blood glucose-lowering effect. This can result in severe hypoglycemia. Ensure you have a high-sugar food or drink like candy, juice, or soda, available and call 911 if your blood sugar continues to drop after consuming them
