Know About Novolog Insulin Peak Time, Onset and Duration of Action

What is Novolog?

Novolog is a fast acting insulin that is used to treat patients with diabetes mellitus. It can be prescribed to adults with type 2 diabetes, and adults and children above the age of 2 with type 1 diabetes. Novolog is also known as insulin aspart. Insulin aspart is a man made insulin that mimics the way the natural hormone works, which is to help glucose enter the body’s cells to be used for fuel. When you inject this insulin, it starts to work quickly to reduce your blood sugar levels. After using insulin aspart, it is advised that you eat within 5 to 10 minutes tp prevent low blood sugar. This medication is usually prescribed together with intermediate or long acting insulin.

Novolog insulin peak time, onset and duration of action

Insulin types such as novolog are usually classified according to the time period they take to control blood sugar levels. To understand how this medication works in the body, it is important you know the meaning of onset, peak, and duration of the medication. The onset refers to how fast it takes before the insulin begins to reduce blood sugar levels in people with diabetes. On the other hand, peak refers to the time when insulin is working the best in the body to reduce blood sugar levels. The duration refers to how long the insulin keeps working in your body. The drug peak time is generally between one to four hours, while novolog onset is between 10 to 20 minutes.

How to take it

Novolog can be injected subcutaneously using an injection pen or a syringe. Your healthcare provider will show you the best part of your body to inject this medication. Usually, it is injected into the fat tissue of the stomach, thigh, upper arm or buttocks. You should not inject this medication on the same spot twice. Instead, change the injection site to reduce the risk of developing lipodystrophy. This medication can also be administered intravenously using an IV by a doctor. You should not take it if you do not know how to use it. Before you use this medication, check whether it contains particles inside or has changed colors. The drug is supposed to be colorless and clear. If you notice particles or discoloration, you should not take this medication. Also, you should not take it if you are allergic to any of its ingredients, including insulin aspart.

Side effects

Remember that your doctor asked you to take novolog because they judged that the benefit of using it outweighs the possible side effects. However, you may experience injection site reactions with symptoms such as redness, pain or irritation as a result of taking this medication. This medicine can also result in low blood sugar or hypoglycemia. 

Symptoms of hypoglycemia include

  • blurred vision
  • fast heartbeat
  • sweating
  • dizziness
  • hunger
  • shaking

If you notice any of these symptoms of low blood sugar, you may be able to treat it by eating fast acting sugars like hard candy, table sugar, fruit juice or non diet soda.
