Maxsulin 50/50 Penset

What is Maxsulin 50/50 Penset?

Maxsulin 50/50 Penset is a premixed (biphasic) human insulin manufactured by Incepta Pharmaceuticals Ltd., combining equal parts (50%) fast-acting regular insulin with 50% intermediate-acting NPH insulin in a convenient prefilled pen device. It provides a more balanced mealtime-to-basal ratio than Maxsulin 30/70, suited to patients with higher mealtime insulin requirements.

Generic Name and Composition

Each mL contains 100 IU of Biphasic Insulin Human, consisting of 50% soluble (regular) insulin and 50% isophane (NPH) insulin, supplied in a 3 mL prefilled pen device.

Indications

• Type 1 diabetes mellitus, as part of a structured insulin regimen
• Type 2 diabetes mellitus when oral antidiabetic agents are insufficient to control blood glucose, particularly in patients with significant post-meal glucose elevation
• Patients who prefer or require a simplified premixed insulin regimen with greater mealtime coverage

How It Works — Mechanism of Action

The regular insulin component acts quickly to control blood glucose rise after meals, while the NPH component provides a delayed, prolonged basal effect. With an equal 50/50 split, this formulation provides stronger mealtime coverage than the 30/70 ratio, lowering blood glucose by promoting cellular glucose uptake and suppressing hepatic glucose production.

Dosage and Administration

• Dosage is strictly individualized by a physician based on blood glucose monitoring, body weight, and meal patterns.
• Administered by subcutaneous injection, typically before breakfast and/or dinner.
• Gently roll/invert the pen before each use to re-suspend the cloudy insulin evenly — do not shake vigorously.
• Inject 15-30 minutes before a meal to align with the regular insulin component's onset.
• 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 premixed formulations, is generally considered safe for use during pregnancy and breastfeeding under close physician supervision. 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 with other insulin brands or types without physician guidance.
• Closely monitor blood glucose, especially when changing dose, insulin brand, meal timing, 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 50/50 Penset appear cloudy?
The NPH component is a suspension, giving the insulin a cloudy appearance. Gently roll or invert the pen to re-suspend it evenly before each injection — do not shake vigorously.

Q2: What does the "50/50" in the name mean?
It refers to the ratio of insulin types: an equal 50% fast-acting regular insulin and 50% intermediate-acting NPH insulin, combined in one premixed formulation.

Q3: How is the Penset different from the vial form?
Both contain the same insulin; the Penset offers a more portable, convenient prefilled pen device, while the vial requires a separate syringe for dosing.

Q4: How does Maxsulin 50/50 Penset compare to Maxsulin 30/70 Penset?
Both are premixed insulin pens from Incepta; Maxsulin 50/50 contains an equal 50% split of regular and NPH insulin, while Maxsulin 30/70 contains 30% regular and 70% NPH, which may better suit different meal and glucose patterns as determined by your physician.
