What is NovoRapid (NovoLog) Penfill?
NovoRapid (NovoLog) Penfill, available from Novo Nordisk Canada, is an insulin pen injection cartridge that contains 300 units (3 mL) of insulin aspart.
It is used to treat patients with type 1 and type 2 diabetes mellitus who require insulin to manage their glucose levels and avoid hypoglycemia.
This rapid-acting insulin is typically prescribed by doctors as a meal time insulin to help reduce blood glucose levels after meals.
How does NovoRapid work?
NovoRapid insulin will begin to lower glucose levels 10-20 minutes after injection. It has a maximum effect between 1-3 hours and can have a lasting effect for up to 3-5 hours.
Since this preparation is short-acting, it is usually used in combination with intermediate-acting or long-acting insulin.
What are the ingredients in NovoRapid?
The active ingredient in NovoRapid is insulin aspart. Non-medical ingredients include: zinc chloride, metacresol, phenol, glycerol, sodium chloride, disodium phosphate dihydrate, sodium hydroxide, hydrochloric acid and water for injection.
How to use NovoRapid Penfill?
Your doctor will personalize our treatment and dose for your specific needs and lifestyle. Your doctor, nurse, diabetes educator or pharmacist will teach you how to inject your insulin.
Due to NovoRapid’s fast onset of action, it should be taken 5-10 minutes before meal times. When necessary it can be taken soon after a meal rather than before.
NovoRapid is to be injected under the skin (subcutaneously). The best places to inject yourself are the abdomen/waist (will work quicker), upper arm, front of thigh or buttocks.
Keep track of where you have injected yourself as it’s good practice to rotate injection site in order to avoid skin complications.
Check the medications label to ensure you are taking the right dose and concentration. Dosage refers to how many units of insulin you require and concentration is how many units are in each milliliter (mL). For example, the concentration may be 100 units/mL (U-100) does not mean 100 units at once.
If you have any questions about how to use the NovoRapid Penfill be sure to discuss with your doctor, pharmacist or diabetes educator.

Medications that can affect insulin
Below are common medications which can affect your insulin treatment and/or glucose levels:

The following drugs may cause your blood sugar to drop (hypoglycemia):
- Other diabetes medications

- Angiotensin converting enzyme (ACE) inhibitors
- Anabolic steroids
The following drugs may cause your blood sugar to rise (hyperglycemia)
- Oral contraceptives (ie birth control pills)

The most common side effect patients experience with this insulin is low blood sugar (hypoglycemia).
If reactions to hypoglycemia are not treated they can result in the loss of consciousness, coma or even death.
If you lose consciousness, you may require a glucagon injection by someone who knows how to use it. Once you regain consciousness, you should consume a sugary snack or glucose tablet.
If you do not respond to the glucagon treatment, you will need to be treated at a hospital.
