Ryzodeg penfill 100 IU 3ml

Ryzodeg Penfill – Insulin Degludec/Aspart 100 IU/ml Cartridge by Novo Nordisk

What is Ryzodeg Penfill?

Ryzodeg 70/30 Penfill contains insulin degludec/aspart co-formulation — 70% ultra-long basal insulin degludec and 30% rapid-acting insulin aspart — in a 3 ml Penfill cartridge for compatible NovoPen reusable devices (NovoPen 4, 5, or Echo). The solution is clear — no rolling or resuspension required. Each cartridge contains 300 IU (210 IU degludec + 90 IU aspart). Preferred by patients using reusable pens for sustainability or requiring the NovoPen Echo's dose memory function.

Generic Name & Composition

Each ml contains 70 IU insulin degludec + 30 IU insulin aspart (both rDNA origin). These co-exist as separate molecules in a clear solution without interacting. After subcutaneous injection: degludec forms a multi-hexameric depot providing 42+ hour basal coverage; aspart is absorbed rapidly (10–20 min) for post-meal control. Each component follows its own independent pharmacokinetic pathway.

Indications

• Type 2 diabetes — once or twice daily injection covering basal and mealtime needs
• Patients using reusable NovoPen devices (NovoPen 4, 5, or Echo)
• Intensification from basal-only to basal-plus therapy
• Type 1 diabetes — in select cases under specialist guidance

How It Works — Mechanism of Action

Degludec (70%): Forms large soluble multi-hexameric subcutaneous depot; slowly releases monomers over 42+ hours — flat, peakless basal coverage. Aspart (30%): Rapid monomeric absorption (onset 10–20 min, peak 1–3 hrs, duration 3–5 hrs) — direct post-meal glucose control. Both activate insulin receptors: GLUT-4 glucose uptake, hepatic output suppression, glycogen synthesis.

Dosage & Administration

Regimen: Once or twice daily with main meal(s). Starting dose: 10 IU once daily with largest meal; titrate by 2 IU every 3–4 days. Penfill use: Load cartridge into compatible NovoPen device. Prime 2 IU. No rolling needed — solution is clear. Dial dose, inject subcutaneously, hold 6 seconds. Rotate sites.

Side Effects

Very common: Hypoglycaemia — from rapid aspart component (post-meal) and/or degludec component (overnight).

Common: Injection site reactions, lipohypertrophy, weight gain.

Uncommon: Lipoatrophy, peripheral oedema.

Rare: Anaphylaxis, severe allergic reactions.

Drug Interactions

Increase hypoglycaemia: Oral antidiabetics, GLP-1 agonists, SGLT-2 inhibitors, ACE inhibitors, MAO inhibitors, alcohol, salicylates.

Reduce effect: Corticosteroids, glucagon, thyroid hormones, thiazides, sympathomimetics, oral contraceptives.

Caution: Beta-blockers mask hypoglycaemia symptoms.

Contraindications

• Hypersensitivity to insulin degludec, aspart, or any excipient
• Active hypoglycaemia; for compatible reusable pen use only

Pregnancy & Lactation

Pregnancy: Limited data; specialist supervision required. Lactation: Not expected at clinically significant concentrations in breast milk.

Precautions & Warnings

• Clear solution — do NOT roll or shake. If cloudy, discard.
• NovoPen compatible devices only — NovoPen 4, 5, Echo.
• Eat within 15 minutes of injection.
• Degludec steady state: Full effect after 2–3 days. Avoid over-titration in first days.

Overdose

Prolonged hypoglycaemia (degludec extends risk beyond 42 hrs). Mild: oral glucose. Severe: IV dextrose or IM glucagon. Extended monitoring required.

Storage Instructions

• Unopened: 2–8°C. Do not freeze.
• In-use (loaded pen): Below 30°C. Do not refrigerate.
• Discard 56 days after first use.

Frequently Asked Questions (FAQs)

Q1: What is the difference between Ryzodeg Penfill and Ryzodeg FlexTouch?
Identical insulin — degludec 70 IU/ml + aspart 30 IU/ml. FlexTouch is pre-filled disposable. Penfill is a refill cartridge for NovoPen 4/5/Echo reusable devices.

Q2: Which pen devices work with Ryzodeg Penfill?
NovoPen 4, NovoPen 5, and NovoPen Echo. Confirm 3ml Penfill compatibility with your device manual.

Q3: Is Ryzodeg Penfill a clear or cloudy solution?
Clear. A solution, not a suspension — do not roll or shake. If cloudy or discoloured, do not use.

Q4: Who manufactures Ryzodeg Penfill?
Novo Nordisk A/S (Denmark).
