What Is Humulin N (Insulin Isophane NPH)?
Humulin N or insulin isophane NPH (intermediate acting insulin), is a cloudy human insulin suspension for type 1 and type 2 diabetes blood sugar control. It provides basal coverage lasting 18-24 hours, starting several hours after injection.
Mix gently by rolling before each dose to ensure even suspension. Available as Humulin N cartridge for convenient pens or vial for cost-effective syringes, it is ideal for patients needing reliable, long-action insulin. Monitor blood sugar regularly as Humulin N dosage depends on diet, exercise and A1C levels.
Humulin N Cartridge vs Vial
Humulin N cartridge fits insulin pens for precise, portable dosing – great for on-the-go diabetes management. Vials suit syringes for bulk use and lower prices, perfect for home injection. Both forms maintain effectiveness when stored properly; choose based on your routine and healthcare provider advice.
Humulin R Regular Insulin Cartridge
Humulin R is short-acting, clear human insulin for mealtime blood sugar spikes or sliding-scale dosing in diabetes treatment. With 30-minute onset, it covers bolus needs faster than Humulin N, lasting 5-8 hours.
Humulin R cartridge works seamlessly in pens for easy injected doses – no mixing required. Use under skin as directed, rotating injection sites to avoid irritation, redness, itching, or lumps from tissue damage. Combine with diet and exercise for optimal blood sugar control.
Humulin N vs Humulin R Differences
| Feature | Humulin N | Humulin R |
| Action Time | Intermediate | Short |
| Appearance | Cloudy (mix) | Clear |
| Best Use | Basal | Bolus |
| Mixing | Yes | No |
Humulin N offers NPH basal coverage for steady blood sugar; Humulin R handles mealtime peaks. Together, they support comprehensive diabetes action.
Humulin N & R Cartridge Dosage Instructions
Humulin N & R cartridge dosage is prescribed by your healthcare provider based on blood sugar levels, carbs, activity and weight. Start low, titrate slowly to avoid low blood sugar (hypoglycemia) risks like shakiness, sweating or anxiety. Never skip doses – inject as directed, monitoring for effects.
Humulin N & R can interact with other medications like beta blockers, steroids or depression drugs, altering effectiveness or raising hypoglycemia danger. Always review other medications and symptoms with your healthcare professional.
Humulin N & R Injection Sites
Inject Humulin N or R in abdomen (fastest absorption), thighs, upper arms or buttocks – rotate sites to prevent skin irritation or lumps. Use 90° angle on clean skin; new needle each time reduces infection risk.
Let refrigerated insulin warm to room temp for comfort. Proper injection sites ensure consistent action and minimize tissue damage.
Proper Storage Guidelines for Humulin N
Store unopened Humulin N at 36-46°F in the refrigerator – don’t freeze as it ruins effectiveness. In-use Humulin N cartridge or vial stays at room temp. (≤86°F) for up to 28-31 days max. Keep away from heat, light and humidity.
For cloudy Humulin N, roll gently between palms 10 times and invert 10 times before injecting – never shake. Proper storage maintains insulin performance; discard if clumped or discolored. Travel with insulated bag and ice pack.
