Humulin® 30/70 Cartridges for Diabetes

Humulin® 30/70 is a premixed human insulin used to help control blood sugar in diabetes. You can access Humulin 70/30 cartridges without insurance with US delivery from Canada. This page explains how the medicine works, who it may suit, and how to use cartridges correctly.

What Humulin Is and How It Works

Humulin® 30/70 combines two insulins in one cartridge. The regular component helps cover mealtime glucose. The intermediate-acting NPH component supports between-meal and overnight needs. Together, they may simplify dosing for people who need both basal and prandial coverage.

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

As part of the premix class, Insulin 70/30 cartridges aim to smooth daily glucose patterns when used as directed by your clinician. Onset and duration vary by person, meal timing, and injection site. Always follow the official label and your prescriber’s instructions.

For background on insulin types, see Types Of Insulin And Uses.

Who It’s For

This treatment is indicated to improve glycemic control in adults and children with diabetes mellitus. It may be considered when a premix can meet meal and basal needs in fewer injections. People with recurrent severe hypoglycemia, allergy to any ingredient, or episodes of diabetic ketoacidosis should not use premix instead of appropriate acute care.

Discuss fit if you have kidney or liver problems, frequent low blood sugar, or variable meal patterns. Review your current regimen if you use other glucose-lowering agents, including sulfonylureas or GLP‑1 therapies. Condition details are available under Type 1 Diabetes and Type 2 Diabetes.

Dosage and Usage

Typical use is subcutaneous injection once or twice daily, often before breakfast and dinner. Your clinician will individualize timing and total units. Resuspend the cloudy suspension gently before each injection by rolling and inverting as directed for the pen system. Inspect to ensure a uniformly milky appearance.

When starting or adjusting, monitor glucose more often. The mealtime portion means injections should align with meals. Rotate sites in the abdomen, thigh, buttock, or upper arm to reduce local reactions. Do not inject into areas that are scarred, tender, or bruised. This premix is for subcutaneous use only. For administration tips with reusable pens, see Types Of Insulin Pen.

Your pen may deliver in 1‑unit increments. Cartridges contain insulin at 100 units per mL; confirm units on your device and your prescribed dose before injecting.

Strengths and Forms

Common presentations include Insulin 70/30 100 IU/mL cartridges supplied in 3 mL cartridges for compatible reusable pens. Packaging and availability can vary by market. The precise products and labels you receive will match your prescription and the dispensing pharmacy’s stock.

Missed Dose and Timing

If you miss a dose, check your glucose. With Human insulin 70/30 cartridges, timing matters because of the mealtime component. If a meal was missed, or it is close to your next scheduled dose, follow your clinician’s guidance or the official label. Do not double doses. Monitor for signs of low or high blood sugar and contact your healthcare professional for individualized advice as needed.

Storage and Travel Basics

Keep unopened cartridges refrigerated according to the label. Do not freeze. Once in use, many insulin cartridges can be kept at room temperature for a limited time; check the official product information for exact durations. Protect from heat and direct light. Keep out of reach of children. Do not use if the suspension remains clumpy or has particles after gentle mixing.

When you travel, carry insulin and supplies in your hand luggage. Bring your prescription label and a travel letter if available. Use a protective case for pens and needles. Pack extra pen needles and glucose supplies. For extreme temperatures, consider cooling sleeves that avoid freezing. Our partners use temperature-controlled handling when required.

See broader guidance in Intermediate Acting Insulin and Type 1 Diabetes Insulin.

Pen Handling and Sharps Disposal

Before each dose, roll and invert the cartridge pen as directed until uniformly cloudy. Attach a new pen needle. Prime the device per the manufacturer’s steps to ensure insulin flow. Dial your dose carefully and inject subcutaneously. Hold the needle in place for several seconds before removing to ensure full dose delivery.

Remove the needle immediately after injection. Do not store pens with a needle attached. Place used needles in a puncture-proof sharps container. Follow local rules for sharps disposal, or use community drop-off programs. Keep spare cartridges and supplies together so you can replace them safely when needed.

Benefits

This premix may reduce the number of daily injections needed to cover meals and between-meal needs. Using cartridges with a reusable pen can support dose accuracy and portability. A consistent routine, paired with meal planning and regular monitoring, may help stabilize day-to-day readings.

Side Effects and Safety

• Low blood sugar symptoms such as shakiness, sweating, or confusion
• Injection site redness, itching, or mild swelling
• Weight gain over time
• Mild fluid retention

Severe hypoglycemia can occur and requires prompt treatment. Allergic reactions, potassium changes, and visual shifts may also occur. Risk of hypoglycemia increases if you skip meals, increase activity, drink alcohol, or use other glucose-lowering agents. If you take insulin along with sulfonylureas, the chance of low blood sugar may rise. Seek urgent care for severe symptoms.

Drug Interactions and Cautions

Medicines that may affect insulin needs include steroids, some antibiotics, antifungals, thyroid drugs, and diuretics. Beta-blockers may mask signs of low blood sugar. Alcohol use can increase hypoglycemia risk. Tell your prescriber about all prescription, OTC, and herbal products you take. Consider medical identification that states you use insulin.

What to Expect Over Time

When used as prescribed with meal timing, the treatment may help lower fasting and post-meal readings. Your plan may evolve with changes in diet, activity, weight, or other medicines. Many people need periodic dose adjustments. Consistent monitoring, record keeping, and follow-up visits can help your clinician optimize your regimen over time.

Compare With Alternatives

Some patients use a lispro premix instead of human insulin premix. You can review Humalog® Mix Cartridges and discuss with your prescriber if a rapid‑acting premix is appropriate. Others may use human premix from a different brand or basal insulin plus separate mealtime insulin. See Insulin Novolin Ge for another human insulin option.

Pricing and Access

We display cash-pay options and Canadian-sourced products with transparent details. Many compare Humulin 70/30 Canadian pricing to local quotations to understand potential savings. You can view current offers, see available pack sizes, and place an order with encrypted checkout. Orders include US shipping from Canada with clearly shown service choices at checkout.

If you manage ongoing therapy, selecting multi-month fills may reduce per-fill fees. You can also align refills with your prescriber visits so documentation stays current.

Availability and Substitutions

Supply can vary by manufacturer and market. If a specific cartridge presentation is unavailable, your prescriber may suggest an equivalent premix or an alternate regimen that meets your needs. Your pharmacy team will dispense the product written on your valid prescription or contact your prescriber for guidance.

Patient Suitability and Cost-Saving Tips

This premix may suit people with predictable meals who prefer fewer daily injections. It may not fit those with highly variable schedules or those at high risk of hypoglycemia. Discuss if you have frequent lows, gastroparesis, or shift work. For budget planning, ask your prescriber about consolidation of visits, longer-duration prescriptions where appropriate, and glucose supplies that match your regimen.

Consider scheduling refill reminders so you have cartridges, pen needles, and testing supplies on hand. Packing a reserve for travel prevents gaps in therapy. Review our Type 2 Diabetes resources to support your plan.
