Humulin 30/70® Cartridges for Diabetes Management

What Humulin® Is and How It Works

Humulin 30/70 Cartridges contain a premixed human insulin: 30% Regular (short-acting) and 70% NPH (intermediate-acting) at 100 units/mL. This mix lowers blood glucose by helping glucose move into cells and by reducing glucose output from the liver. It is given by subcutaneous injection and is usually taken twice daily with meals for people with diabetes who benefit from a premix schedule.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba, and licensed pharmacists review prescriptions before dispensing. We work with vetted, licensed international partner pharmacies to supply authentic brand medicines, offering a broad selection at affordable pricing.

Humulin 30/70 cartridges are designed for compatible reusable insulin pens. They provide fixed basal and mealtime coverage in one step. Many people in the U.S. know a similar mix as Humulin 70/30. You can order cartridges from Canada with prompt, express, cold-chain shipping.

Dosage and Usage

• Humulin 30/70 is often injected twice daily, about 30 minutes before breakfast and dinner. The exact dose and timing are individualized by the prescriber.
• Roll the cartridge gently between your hands and invert it several times until the suspension looks uniformly cloudy. Do not use if you see clumps, frosting, or particles after mixing.
• Check that your reusable pen is compatible with 3 mL Humulin cartridges and U-100 insulin. Inspect the label each time you use a new cartridge.
• Wash hands. Attach a new sterile needle. Prime the pen per the manufacturer (often 1–2 units) until a drop appears at the tip.
• Dial the prescribed dose. Choose an injection site in the abdomen, thigh, upper arm, or buttock. Pinch a skin fold if advised and insert the needle into subcutaneous tissue.
• Press and hold the injection button until the dose counter returns to zero, then keep the needle in place for 10 seconds before removing it.
• Rotate injection sites with each dose to reduce lipodystrophy. Avoid injecting into areas that are tender, bruised, or scarred.
• If you miss a dose and it is close to the next scheduled dose, do not double the dose. Check glucose and follow your prescriber’s guidance.
• Never share pen devices or needles. Do not inject intravenously or use in an insulin pump.

• Unopened cartridges: store in a refrigerator at 2–8 °C (36–46 °F). Do not freeze. Keep in the original carton to protect from light.
• In-use cartridges: you may store at room temperature, generally below 25–30 °C (77–86 °F). Discard after the in-use period on the label (often up to 28 days), even if insulin remains.
• Do not expose to direct heat or sunlight. Do not use if frozen or if the suspension remains lumpy after mixing.
• Travel tips: carry insulin in your hand luggage in an insulated bag. Use cold packs but do not place cartridges directly on ice. Bring spare needles, a backup cartridge, and your prescription documents.
• For road trips, avoid leaving insulin in a hot or freezing car. Use a travel case that keeps temperature stable during the journey.

Benefits and Savings

Humulin 30/70 offers basal and mealtime insulin coverage in one injection. The premix can simplify routines for those with regular meals. Cartridges work with reusable pens, which may reduce plastic waste compared with single-use pens and give clear dose dialing. The cloudy suspension is easy to resuspend before each use.

Ordering from YouDrugstore provides typical savings of 60–80% compared with common U.S. prices. Many shoppers compare humulin 30 70 cartridge price or humulin 70 30 cartridge price when budgeting. You may also see searches for huminsulin 30 70 penfill price in markets where Huminsulin is the brand name. We display Canadian pricing transparently on each product page.

Choose multi-month supplies when appropriate. Bulk promotions can lower your per‑month costs. You can also set up reorder reminders so you never run short of supplies.

Side Effects and Safety

• Hypoglycemia (low blood sugar), which may cause sweating, shakiness, fast heartbeat, hunger, headache, or confusion
• Injection-site redness, itching, mild pain, or swelling
• Weight gain and peripheral edema
• Allergic skin reactions such as rash or pruritus
• Lipodystrophy (lipoatrophy or lipohypertrophy) at injection sites
• Itching of hands or feet and mild fluid retention

Serious but less common risks include severe hypoglycemia, generalized allergic reactions, and hypokalemia. Rapid improvement in glucose control may temporarily worsen diabetic retinopathy. The risk of hypoglycemia increases if insulin doses are too high or when used with sulfonylureas or other glucose‑lowering drugs. Do not use Humulin 30/70 for diabetic ketoacidosis (DKA) or in an insulin pump.

Onset Time

Because Humulin 30/70 contains Regular insulin, onset usually begins about 30 minutes after injection. The Regular component peaks within 2–4 hours, while the NPH component peaks later and can last up to 18–24 hours. Many people see fasting and premeal glucose improve within days as doses are set. A1C changes are typically assessed after 8–12 weeks of a stable dose.

Compare With Alternatives

Rapid‑acting analog premixes may suit those who need a faster onset with meals. For example, you can consider Humalog® Mix Kwikpens, which contain insulin lispro mixes and begin working more quickly than human premixes with Regular insulin.

If you prefer vials and syringes or need a different delivery format, the same insulin blend is available as a vial. See Humulin® 30 70 Vial for details on vial-based dosing and storage.

Some patients compare human premixes (e.g., Humulin 30/70) with other ratios or brands, including products known as humulin 70 30 cartridges in the U.S. Your prescriber can help select the right formulation for your routine and glycemic targets.

Combination Therapy

• Metformin plus Humulin 30/70 is common in type 2 diabetes.
• SGLT2 inhibitors or DPP‑4 inhibitors can be used with premix insulin when appropriate.
• GLP‑1 receptor agonists may be combined; dose adjustments of insulin may reduce hypoglycemia risk.
• When used with sulfonylureas or other insulin products, consider lowering doses to limit hypoglycemia.
• Always review timing with other agents to avoid overlapping peaks that increase low‑glucose risk.

Patient Suitability and Cost-Saving Tips

Humulin 30/70 may suit adults with type 2 diabetes who prefer a twice‑daily premix and have predictable meals. It may also fit some people with type 1 diabetes when a simplified premix schedule is selected by their clinician. It is not for use in pumps or for treating DKA.

People who need flexible meal timing or detailed carb counting may prefer a basal‑bolus plan. Those with recurrent hypoglycemia, significant hepatic or renal impairment, or a history of severe insulin allergy require careful evaluation. Human insulin is frequently used in pregnancy; clinicians adjust dosing as needs change during gestation and postpartum.

For savings, compare pack sizes and consider reusable pens with cartridges, which can be cost‑effective over time. Multi‑pack orders often reduce the per‑month cost. Reorder reminders help you maintain continuous supply. Some customers search for huminsulin 30 70 cartridge or huminsulin 30 70 100iu for international equivalents; we dispense Canadian Humulin products at 100 units/mL.
