Humulin 30/70 Vial® Premixed Human Insulin for Diabetes Care

What Humulin 30/70® Is and How It Works

Humulin 30/70® Vial is a premixed human insulin suspension. It contains 30% regular insulin (short‑acting) and 70% isophane insulin, also called NPH (intermediate‑acting). It helps manage blood glucose in adults and children with type 1 or type 2 diabetes. The mix provides meal coverage and basal support in one injection. Many people compare Humulin 30/70 Vial cost without insurance when planning refills, but dosing decisions should remain clinical.

CanadianInsulin is a prescription referral service. Prescriptions are verified with your clinic, and orders are filled by licensed Canadian pharmacies.

This vial is for subcutaneous injection only. Typical use is twice daily before meals. Regular insulin starts first to cover food, and NPH extends control between doses. The cloudy suspension must be gently mixed before drawing a dose. Use U‑100 insulin syringes for accurate measurement.

Dosage and Usage

• Dosing is individualized: Your prescriber sets the dose based on glucose targets, meals, and activity.
• When to inject: Usually 30 minutes before breakfast and 30 minutes before the evening meal.
• Initiation: Many start with two daily injections. The morning dose often exceeds the evening dose when meal size is larger earlier in the day.
• Titration: Clinicians may adjust by 2–4 units or 10–15% every few days based on fasting and pre‑meal readings.
• Missed dose: If you miss a dose and it is close to the next dose, skip the missed dose. Never double up. Check glucose more often and follow your care plan.
• Do not use in pumps or IV: Premixed insulin is not for insulin pumps or intravenous use.
• Resuspension: Roll the vial gently between the palms 10 times. Invert 10 times until uniformly cloudy. Do not shake hard.
• Drawing the dose: Use U‑100 syringes. Clean the stopper, inject air equal to the dose, then withdraw the dose carefully.
• Injection sites: Abdomen, thigh, upper arm, or buttocks. Rotate sites to reduce lipodystrophy.
• Timing with meals: Eat within about 30 minutes after injection to limit hypoglycemia.
• Supplies: Pair with Bd Ultrafine Ii Syringes for precise dosing.
• Glucose checks: Monitor fasting and pre‑meal levels to guide safe adjustments with your clinic.

• Storage—unopened vials: Refrigerate at 2–8°C (36–46°F). Do not freeze. Keep away from light.
• Storage—after first use: Keep at room temperature (below 25–30°C/77–86°F) or refrigerated. Discard 31 days after first puncture.
• Do not use if: The insulin is frozen, clumped, or has particles/strings after mixing.
• Travel: Carry vials and syringes in your hand luggage with a cold pack. Avoid direct sun and car glove boxes. Keep the label and a copy of your prescription for security checks.
• Shipping: Orders ship with prompt, express, cold‑chain handling to protect potency.
• Disposal: Place used needles and syringes in an approved sharps container.

Benefits and Savings

Premixed insulin combines meal coverage and basal support in one vial. It can reduce the number of daily injections compared with separate short‑ and intermediate‑acting insulins. Many users find it fits a regular meal routine and provides steady daytime and overnight control. The familiar human insulin profile supports predictable timing when meals are consistent.

Premixes can simplify training and daily preparation. The vial format works with standard U‑100 syringes available in most settings. You can coordinate doses with your meal plan and activity to manage both post‑meal spikes and between‑meal levels. Clinicians can adjust total dose and morning/evening split to meet targets.

Many customers save 60–80% vs typical U.S. prices. Savings can help if you pay without insurance. We source through licensed, vetted partner pharmacies in Canada, offering authentic brand medications, broad selection, and value‑focused pricing.

Side Effects and Safety

• Hypoglycemia (shakiness, sweating, fast heartbeat, hunger, headache, confusion)
• Injection‑site reactions (redness, swelling, itching)
• Weight gain and peripheral edema
• Allergic reactions (rash, pruritus)
• Lipodystrophy at injection sites if not rotated
• Hypokalemia (low potassium), especially with high doses or diuretics

Severe hypoglycemia can be dangerous. Review signs and how to treat low blood sugar with your clinic. Risk increases when used with insulin secretagogues such as sulfonylureas or with alcohol. Do not share syringes or vials. Premixed insulin is not for diabetic ketoacidosis, insulin pumps, or IV use. Fluid retention may occur with thiazolidinediones. Tell your clinician about kidney, liver, or heart conditions and all medicines you use.

Onset Time

The regular insulin component begins lowering glucose about 30–60 minutes after injection. Peak effect from the regular portion occurs around 2–4 hours. The NPH portion adds a later peak between 4–12 hours and extends activity up to about 18–24 hours. Glucose readings often begin to improve within days as steady dosing is established. Your clinician may fine‑tune doses over 1–3 weeks to stabilize fasting and pre‑meal targets.

Compare With Alternatives

Some patients use separate insulins instead of a premix. For example, Humulin R 100u Ml 10ml offers flexible short‑acting dosing for meals, paired with an intermediate or basal insulin. This can fit variable meal sizes but requires more injections and planning.

Non‑insulin options can also support type 2 diabetes management. Rybelsus® is an oral GLP‑1 receptor agonist taken daily. Trulicity® is a once‑weekly GLP‑1 injection that may reduce appetite and support weight loss while lowering A1C. Mounjaro® (tirzepatide) is a GIP/GLP‑1 agent given weekly, with A1C and weight benefits in clinical trials. These agents are often used before or with insulin in type 2 diabetes under medical guidance.

Whichever path you follow, regular glucose monitoring helps guide therapy changes. Many customers also add supplies such as Accu Chek Aviva Test Strips for home testing.

Combination Therapy

• Metformin plus premixed insulin to improve fasting and post‑meal control.
• SGLT2 inhibitors with insulin for added A1C reduction and potential weight/heart‑kidney benefits.
• GLP‑1 receptor agonists with insulin to reduce insulin needs and limit weight gain.
• Sulfonylureas with insulin may increase hypoglycemia risk; clinicians often reduce or stop the sulfonylurea.
• Basal‑bolus transitions: a clinician may move from premix to separate basal and bolus doses if meals become variable.
• Illness plans include more frequent testing and ketone checks in type 1 diabetes when unwell.

Patient Suitability and Cost‑Saving Tips

Humulin 30/70 Vial can suit people who prefer fewer daily injections and have predictable meal times. It is an option for type 1 diabetes with clinician oversight and for type 2 diabetes when oral agents no longer meet targets. It is not appropriate for insulin pumps, IV use, or for treating diabetic ketoacidosis. Those with frequent snack patterns or highly variable meal timing may need a different plan.

To reduce costs, consider a multi‑month supply when appropriate, and align refills to limit separate shipments. Set a reminder to reorder before your current vial reaches 31 days in use. Value comes from authentic branded insulin shipped with temperature control. If you need syringes or test supplies, adding them to the same order may simplify logistics.
