Maxsulin N PenSet

What is Maxsulin N PenSet?

Maxsulin N PenSet is an intermediate-acting human insulin (NPH/Isophane) manufactured by Incepta Pharmaceuticals Ltd., supplied in a convenient prefilled pen device. It is used to control blood glucose in people with diabetes mellitus who require insulin therapy, offering a cloudy suspension with a delayed, prolonged action profile compared to regular insulin.

Generic Name and Composition

Each mL contains 100 IU of Insulin Human (NPH, Isophane suspension), supplied in a 3 mL prefilled pen device.

Indications

• Type 1 diabetes mellitus, as part of a basal-bolus insulin regimen
• Type 2 diabetes mellitus when oral antidiabetic agents are insufficient to control blood glucose
• Gestational diabetes, as directed by a physician

How It Works — Mechanism of Action

NPH insulin is a suspension of insulin combined with protamine, which delays its absorption and prolongs its glucose-lowering action compared to regular (soluble) insulin. It lowers blood glucose by facilitating cellular glucose uptake, particularly in muscle and fat tissue, and by suppressing hepatic glucose production.

Dosage and Administration

• Dosage is strictly individualized by a physician based on blood glucose monitoring, body weight, and lifestyle.
• Administered by subcutaneous injection, typically once or twice daily.
• Gently roll/invert the pen before use to re-suspend the cloudy insulin — do not shake vigorously.
• Rotate injection sites within the same body region (abdomen, thigh, upper arm) to reduce lipodystrophy.
• Always prime the pen and check for proper insulin flow before each injection.

Side Effects

Common: Hypoglycemia, injection site reactions (redness, swelling, itching), lipodystrophy with repeated injections at the same site.

Uncommon: Weight gain, peripheral edema (especially when starting therapy).

Rare: Severe allergic reactions (generalized rash, angioedema, anaphylaxis), hypokalemia.

Drug Interactions

May increase hypoglycemia risk: Oral antidiabetic agents, ACE inhibitors, salicylates, alcohol.

May reduce insulin effect / raise blood glucose: Corticosteroids, thiazide diuretics, thyroid hormones, oral contraceptives.

Other considerations: Beta-blockers may mask symptoms of hypoglycemia; inform your doctor of all medicines you are taking.

Contraindications

• Known hypersensitivity to insulin human or any excipient
• Episodes of hypoglycemia requiring caution in dosing adjustment

Pregnancy and Lactation

Human insulin, including NPH formulations, is generally considered safe for use during pregnancy and breastfeeding under close physician supervision, as insulin does not cross into breast milk in a way that affects the infant. Dose requirements often change during pregnancy and require close monitoring.

Precautions and Warnings

• Never share pen devices between patients, even with a new needle, due to infection transmission risk.
• Always verify the insulin type before each injection — do not interchange NPH, regular, or premixed insulins without physician guidance.
• Closely monitor blood glucose, especially when changing dose, insulin brand, or activity/diet patterns.
• Be aware of signs of hypoglycemia (sweating, palpitations, confusion) and carry a fast-acting sugar source.
• Store the pen correctly — refrigerate unopened pens, keep in-use pens at room temperature, away from direct heat and sunlight.

Overdose

Overdose may cause severe hypoglycemia, with symptoms ranging from sweating and confusion to seizures and loss of consciousness. Mild cases can be managed with oral glucose; severe cases require immediate medical attention, including intravenous glucose or glucagon administration.

Storage Instructions

• Store unopened pens in a refrigerator (2-8°C); do not freeze.
• Once in use, the pen may be kept at room temperature (below 30°C) for up to 4 weeks, away from direct heat and light.
• Keep out of reach of children.
• Do not use after the expiry date printed on the pack.

Frequently Asked Questions

Q1: Why does Maxsulin N appear cloudy?
NPH insulin is a suspension, which gives it a cloudy appearance. Gently roll or invert the pen to re-suspend it evenly before each injection — do not shake vigorously.

Q2: How is Maxsulin N different from Maxsulin R?
Maxsulin N is an intermediate-acting (NPH) insulin with a delayed, prolonged effect, while Maxsulin R is a fast-acting regular insulin used to control blood glucose around meals.

Q3: Can I reuse pen needles?
Pen needles are intended for single use; reusing needles can cause pain, infection, and inaccurate dosing due to needle dulling.

Q4: How does Maxsulin N PenSet compare to Maxsulin 30/70?
Maxsulin N contains only intermediate-acting NPH insulin, while Maxsulin 30/70 is a premixed insulin combining 30% regular and 70% NPH insulin for combined mealtime and basal coverage.
