Novorapid® Cartridge for Rapid Mealtime Insulin Control

What Novorapid® Is and How It Works

Novorapid® (insulin aspart) is a rapid-acting mealtime insulin used to control blood glucose in adults and children with diabetes. It is supplied in 3 mL Penfill cartridges (100 units/mL) for use with compatible reusable insulin pens. The clear, colorless solution starts working quickly to cover carbohydrates at meals and correct high readings. If you pay novorapid cartridge without insurance, Canadian pricing can ease out-of-pocket costs.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba. Prescriptions are reviewed by licensed pharmacists before dispensing.

We partner with licensed, vetted international pharmacies to supply authentic brand medications across a wide selection at affordable prices.

Insulin aspart works by replacing the body’s own insulin, enabling glucose to move from the blood into cells for energy and storage. Compared with human regular insulin, Novorapid® is absorbed faster after subcutaneous injection. It is typically taken within 5–10 minutes before a meal, or right after starting a meal if needed. Dosing is individualized based on your treatment plan, carbohydrate intake, activity, and glucose targets. Many patients use Novorapid® as part of a basal-bolus regimen alongside a long-acting insulin.

Novorapid® Penfill cartridges fit specific reusable pens such as NovoPen devices. They are not for insulin pumps and should not be mixed with other insulins in the cartridge. Do not share pens or needles.

Dosage and Usage

• Use as directed in your prescription. Mealtime doses are individualized in units.
• Inject subcutaneously in the abdomen, thigh, upper arm, or buttocks. Rotate sites to reduce skin changes.
• Give 5–10 minutes before meals. If needed, dosing can occur immediately after starting the meal.
• Use only with compatible reusable pens designed for Penfill cartridges. Follow the pen’s user manual.
• Inspect the cartridge. Use only if the solution is clear and colorless with no particles or clumps.
• Insert the cartridge into the pen as instructed by the pen manufacturer.
• Always attach a new sterile pen needle for each injection.
• Prime the pen (for example, 1–2 units) until you see insulin at the needle tip.
• Dial the prescribed dose. Pinch the skin if advised. Insert the needle at the recommended angle.
• Inject and keep the needle in place for 6–10 seconds to ensure full dose delivery.
• Remove and safely discard the needle in a sharps container. Do not store the pen with a needle attached.
• Do not share pens, cartridges, or needles with anyone.
• Do not mix Novorapid® with other insulins in a Penfill cartridge or pen.
• Missed dose: if a meal dose is missed, check glucose and follow your care plan. Do not double doses.

• Storage (unopened): refrigerate cartridges at 2–8 °C (36–46 °F). Do not freeze. Keep away from the freezer compartment.
• Storage (in-use cartridge in a pen): keep below 30 °C (86 °F) and use within 28 days. Do not refrigerate a pen with an in-use cartridge.
• Protect from heat and light. Do not expose to temperatures above 30 °C (86 °F).
• Travel: carry insulin in an insulated bag with cold packs. Do not place vials or cartridges directly against ice packs. Keep a backup supply and pen needles.
• Do not use if insulin has been frozen, overheated, or appears cloudy or discolored.
• For shipping, we use prompt, express, cold-chain shipping to maintain product integrity.

Benefits and Savings

Novorapid® offers fast onset for mealtime coverage, flexible dosing around food intake, and predictable action in most people. Penfill cartridges let you use a durable pen with clear dosing clicks and memory features on some models, which many patients find convenient. The compact pen-and-cartridge setup also simplifies daily carrying and travel.

Buying through a Canadian pharmacy can lower the novorapid cartridge price compared with typical U.S. retail costs. Many customers report 60–80% savings. If you pay novorapid cartridge cash price, you may still see strong savings versus U.S. pharmacies. Multi-month supplies and occasional bulk promotions can further reduce the per-month novorapid cartridge cost.

Side Effects and Safety

• Hypoglycemia (low blood sugar): shakiness, sweating, fast heartbeat, hunger, headache, confusion.
• Injection site reactions: redness, swelling, itching, or mild pain.
• Lipodystrophy or cutaneous amyloidosis at injection sites with repeated use.
• Weight gain or mild fluid retention.
• Allergic reactions such as rash or hives.
• Low potassium (hypokalemia) in rare cases.

Serious risks include severe hypoglycemia requiring assistance, anaphylaxis, and significant low potassium, which may affect heart rhythm. The risk of hypoglycemia increases if Novorapid® is used with insulin secretagogues such as sulfonylureas or when combined with basal insulin. Adjustments to doses and careful glucose monitoring reduce this risk. Discuss illness, changes in activity, kidney or liver impairment, pregnancy, or breastfeeding with your clinician.

Onset Time

After subcutaneous injection, Novorapid® usually starts lowering glucose within about 10–20 minutes. Peak effect often occurs around 1–3 hours, and the action typically lasts 3–5 hours. Glucose metrics may improve in the first days as you match doses to meals. Expect refinements to mealtime dosing over the first 1–4 weeks as patterns and carbohydrate intake are assessed.

Compare With Alternatives

Insulin lispro (Humalog) is another rapid-acting mealtime insulin with a similar onset and duration. Some people switch between aspart and lispro based on availability, price, or prescriber preference. Dose conversions are often unit-to-unit under medical guidance.

Faster aspart (Fiasp) adds niacinamide to speed absorption. It may begin working slightly sooner than Novorapid®, which can help with high–glycemic index meals in some users. Not everyone needs the faster profile, and tolerability varies.

Insulin aspart biosimilars like Trurapi cartridge may offer cost advantages where available. If you are comparing novorapid penfill cartridges with other brands, review pen compatibility, action profile, and total monthly cost.

Combination Therapy

• Basal-bolus: long-acting insulin once or twice daily plus Novorapid® at meals.
• With metformin: common in type 2 diabetes to improve insulin sensitivity.
• With SGLT2 inhibitors or GLP-1 receptor agonists: may reduce insulin requirements and support weight goals.
• With sulfonylureas: consider reducing sulfonylurea dose to lower hypoglycemia risk.
• Correction dosing: small extra doses of Novorapid® to correct high readings per your plan.

Patient Suitability and Cost-Saving Tips

Novorapid® is used in type 1 diabetes and in type 2 diabetes when rapid-acting insulin is needed for meals or corrections. It is not for diabetic ketoacidosis treatment and is not indicated for insulin pumps when supplied as Penfill cartridges. Those with frequent severe hypoglycemia or unawareness, significant kidney or liver disease, or recurrent site reactions need closer supervision.

Discuss pen compatibility if you already own a device. Novorapid® Penfill cartridges work only with certain reusable pens. Always verify the pen model, needle length, and dose increment (for example, 0.5 or 1 unit).

To manage the novorapid cartridge price, consider a multi-month order to lower shipping costs per month. You can set gentle reorder reminders so you do not run short. If you pay novorapid cartridge out of pocket, compare the per-unit cost across package sizes and ask about bulk promotions when available.
