It binds to insulin receptors, supporting glucose uptake in muscle and fat while reducing hepatic output. Onset may occur within minutes when taken at mealtime. Novorapid Cartridge is typically paired with a long-acting insulin to cover baseline needs.

Who It’s For
This insulin aspart cartridge is indicated to improve glycemic control in adults and pediatric patients with diabetes mellitus. It is not suitable during episodes of hypoglycemia or for anyone with a known hypersensitivity to insulin aspart or formulation excipients.
Those with frequent severe lows, significant renal or hepatic impairment, or hypoglycemia unawareness may require closer monitoring. Learn more in our Diabetes category.
Dosage and Usage
Administer by subcutaneous injection shortly before the meal begins or right after starting to eat, as directed on the official label. Typical injection sites include the abdomen, thigh, or upper arm. Rotate injection sites within the same region to reduce skin changes.
Use a new pen needle for every injection. Prime the pen per device instructions before dosing. This treatment is often combined with a basal insulin as part of a multiple daily injection plan. Cartridges are designed for reusable pens and are not intended for IV use or for most insulin pumps. Follow the product label if your prescriber changes insulin types.
Strengths and Forms
Common presentation: Novorapid 100 units/mL 3 mL cartridge. Availability can vary by pharmacy and pack size. The clear solution is intended for use with compatible reusable pens.
See more options within Insulin Cartridges. Cartridges are typically Penfill-style refills designed to fit specific pen platforms; confirm compatibility with the device instructions.
Missed Dose and Timing
If a mealtime dose is missed, check blood glucose. If the meal has just begun, follow the label or consult your clinician for guidance on taking the missed dose. Do not double doses to make up for one that was missed. Extra monitoring may be prudent after any missed or delayed mealtime injection.
Storage and Travel Basics
Unopened cartridges are generally stored refrigerated and protected from light. Do not freeze, and discard any product that has been frozen. In-use cartridges are usually kept at room temperature and used within the time period on the label. Keep away from heat or direct sunlight and store out of reach of children.
For travel, keep your pen, cartridges, and needles in carry-on baggage with a copy of your prescription. Use insulated storage to help protect from temperature extremes. Label guidance may differ by country; check the official monograph for specific temperature ranges. Our partner pharmacies use temperature-controlled handling when required.
Pen Handling and Sharps Disposal
Novorapid Penfill cartridges are intended for compatible reusable pens. Confirm your device match prior to loading. Many patients pair a pen such as the Novopen 4 Novo Nordisk with fine-gauge needles like Bd Nano Pro Pen Needles.
Before each injection, attach a new needle, prime according to the pen manual, and dial the prescribed dose. Inspect the solution; do not use if cloudy, colored, or if you see particles. Never share pens or needles. Dispose of used needles in an approved sharps container and follow local guidance for disposal.
Benefits
- Mealtime control: addresses post-meal glucose rises.
- Pen accuracy: dialed dosing supports fine dose adjustments.
- Refill convenience: replace the cartridge, keep your pen.
- Portability: compact format for daily routines and travel.
- Clear solution: easy visual check before injection.
Side Effects and Safety
Common effects may include hypoglycemia, injection site redness or itching, lipodystrophy at injection sites, mild edema, headache, or rash. Weight change can occur with insulin therapy.
Serious risks can include severe hypoglycemia, generalized allergic reactions, and hypokalemia. Beta-blockers may mask adrenergic warning signs of low blood sugar. Stop and seek medical help if you experience signs of a severe allergic reaction such as widespread rash, trouble breathing, or facial swelling.
Drug Interactions and Cautions
- Agents affecting glucose: other antidiabetic medicines, steroids, thyroid agents, and certain antivirals may change insulin needs.
- Beta-blockers and similar drugs: may blunt recognition of hypoglycemia symptoms.
- Thiazolidinediones: combined use may increase fluid retention; monitor for heart failure symptoms.
- Alcohol: can raise or lower glucose unpredictably.
Do not mix different insulins in the same pen or cartridge. Use caution with renal or hepatic impairment. Review all medicines and supplements with your healthcare professional.
What to Expect Over Time
With consistent mealtime dosing and monitoring, many patients see smoother post-meal glucose profiles. Individual response varies. Keep logs of blood sugar readings, meals, activity, and doses to support discussions with your prescriber. Any change in insulin type or delivery method may require closer monitoring during the transition period.
Compare With Alternatives
Faster aspart may be suitable for some patients; see Buy Insulin Cartridges for that option. Another mealtime insulin is insulin lispro; compare with Cartridge 100 Units Ml. Some regions also offer biosimilar aspart products, such as Trurapi; speak with your prescriber about suitability and substitution rules.

How do cartridges compare with vials or prefilled pens?
Cartridges fit reusable pens, offering dialed dosing and the ability to replace only the refill. Prefilled pens are disposable and already assembled, while vials require syringes. Many find pens simpler for accurate mealtime doses. Novorapid can be supplied as cartridges for compatible pens, which may reduce plastic waste compared with single-use pens. The best format depends on your prescription, manual dexterity, and dosing needs discussed with your prescriber.
Can I use these cartridges with my current pen?
Check your pen’s compatibility list in the device instructions. Penfill-style refills are designed for specific reusable pens. For example, many patients use a cartridge with a Novo Nordisk pen platform approved for that refill. If unsure, ask your pharmacist or clinician to confirm. Never force a cartridge into an incompatible device, and always prime and use a new needle for each injection per the pen manual.
Are insulin aspart cartridges suitable for children?
Insulin aspart cartridges are indicated for pediatric patients when a mealtime insulin is prescribed. Dosing and timing should follow the official labeling and your clinician’s directions. Caregivers should receive training on pen setup, priming, dose dialing, and recognition of low blood sugar. Schools or caregivers may need written instructions for management of hypoglycemia, meal routines, and activity plans. Speak with your healthcare professional about age-specific considerations.
Can I put a cartridge into an insulin pump?
No. Cartridges are intended for compatible reusable pens, not for standard insulin pumps. While insulin aspart can be used in some pumps, that typically involves pump-specific reservoirs and infusion sets sourced for that device, often filled from vials. Follow the manufacturer’s guidance for pump therapy and do not modify a cartridge for pump use. If you are considering a pump, discuss device options and supplies with your diabetes care team.
How long can an opened cartridge be used?
Follow the storage and in-use time on the official label. In general, an in-use cartridge is kept at room temperature and used within the labeled number of days, protected from heat and light. Do not refrigerate an in-use pen unless the label instructs otherwise. Discard any cartridge that has been frozen, appears cloudy or discolored, or shows particles. Keep out of reach of children and do not share pens or needles.
What needle type should I use with my pen?
Use a compatible pen needle size and gauge listed in your pen’s instructions. Many users prefer shorter, finer needles for comfort, but the correct length depends on your body type, injection technique, and prescriber guidance. Always use a new sterile needle for each injection. Dispose of used needles in a puncture-resistant sharps container, and follow local regulations for safe disposal.
What if I see air bubbles or a leak during dosing?
If you notice air bubbles, follow your pen’s priming steps to remove air before dialing the dose. A small drop at the needle tip after injection can be normal. If leakage seems significant, review injection technique, needle attachment, and priming steps. Do not reuse needles. If problems continue, contact your pharmacist or clinician. Replace any damaged pen or cartridge and monitor blood glucose more closely until the issue is resolved.
