NOVOMIX-30 FLEXPEN (100IU/ML)

The NOVOMIX-30 FlexPen (100 IU/ML) is a widely used and convenient pre-filled insulin pen for individuals with diabetes. Here’s a detailed description:

NOVOMIX-30 FlexPen (100 IU/ML): A Premixed Insulin Analog for Balanced Diabetes Control

The NOVOMIX-30 FlexPen contains insulin aspart, a modern insulin analog, in a premixed suspension. It’s designed to provide effective blood sugar control for adults, adolescents, and children (typically aged 10 years and above for type 1 diabetes) with diabetes mellitus (both Type 1 and Type 2). The “30” in NOVOMIX-30 signifies its unique ratio: 30% rapid-acting insulin aspart and 70% longer-acting protamine insulin aspart. This combination allows for a single injection to address both immediate post-meal blood sugar spikes and provide sustained background insulin levels. The concentration is 100 IU/ML, which is the standard concentration for most insulin pens.

How Insulin Aspart (NovoMix-30) Works:

Insulin aspart is an insulin analog that has been modified to act faster than traditional human insulin. NovoMix-30’s dual-action profile is attributed to its two components:

• 30% Rapid-Acting Insulin Aspart: This component starts to lower blood sugar levels very quickly, typically within 10-20 minutes after injection. Its purpose is to effectively manage the rapid increase in blood glucose that occurs right after consuming a meal.
• 70% Longer-Acting Protamine Insulin Aspart: In this part, insulin aspart is bound to protamine, which slows down its absorption from the injection site. This provides a more prolonged and sustained effect, helping to control blood sugar levels between meals and throughout the night.

Together, these two components offer a balanced approach to insulin therapy, aiming to mimic the body’s natural insulin response to food while also providing essential basal insulin coverage. This can simplify the daily insulin regimen for many individuals.

Onset, Peak, and Duration of Action (General):

• Onset of Action: 10-20 minutes
• Peak Effect: 1-4 hours after injection
• Duration of Action: Up to 24 hours (though individual responses can vary depending on dose, injection site, blood flow, temperature, and physical activity).

Key Features and Benefits of NOVOMIX-30 FlexPen:

• Comprehensive Glycemic Control: Effectively manages both immediate post-meal glucose excursions and provides sustained background insulin levels, contributing to overall blood sugar stability.
• Convenience of a Premixed Insulin: The single injection simplifies daily insulin regimens, making it easier for patients to adhere to their treatment plan.
• User-Friendly FlexPen: As a pre-filled, disposable pen, it is ready to use and allows for accurate dosing from 1 to 60 units in 1-unit increments.
• Rapid Action: Its rapid-acting component allows for injection immediately before a meal, or even shortly after, offering flexibility in meal timing.
• Improved Quality of Life: By maintaining stable blood sugar levels, it helps reduce the risk of long-term diabetes complications such as eye disease, kidney disease, nerve damage, and cardiovascular problems.

Important Usage and Administration:

• Subcutaneous Injection Only: NOVOMIX-30 FlexPen must be injected under the skin (subcutaneously) into the abdomen (front of your waist), thigh, buttocks, or upper arm. It should never be injected directly into a vein (intravenously) or a muscle (intramuscularly), nor used in insulin infusion pumps.
• Thorough Mixing is CRUCIAL: As it is a cloudy suspension, the FlexPen must be gently rolled between the palms at least 10 times and then inverted (turned upside down and back up) at least 10 times immediately before every injection until the contents appear uniformly cloudy white or milky. Do not shake vigorously, as this can create foam and lead to inaccurate dosing.
• Priming the Pen: Before each injection, the pen should be primed (e.g., by dialing 2 units and expelling it into the air) to ensure proper insulin flow and remove any air bubbles from the needle and cartridge.
• Timing of Injection: NOVOMIX-30 is generally administered immediately (up to 10 minutes) before your meal or carbohydrate snack. If necessary, it can be given soon after starting a meal. Consuming a meal promptly after injection is important to prevent low blood sugar.
• Individualized Dosage: The precise dose and timing of injections are determined by your healthcare provider based on your individual blood glucose monitoring results, dietary habits, physical activity, and overall treatment plan.
• Injection Site Rotation: To prevent localized skin changes such as lipodystrophy (skin thickening, shrinking, or lumps) and cutaneous amyloidosis, it is vital to rotate injection sites regularly within the same general area with each injection.
• Never Share Pens or Needles: NOVOMIX-30 FlexPens are for single-patient use only. Sharing pens or needles can lead to the transmission of infections and blood-borne pathogens. Always use a new, sterile needle for each injection.
• Visual Inspection: Before each use, inspect the suspension. After mixing, it should appear uniformly cloudy white. Do not use if it looks clear, contains solid particles, or appears frosted.

Storage:

• Unopened FlexPens: Store in a refrigerator (2°C – 8°C / 36°F – 46°F). Do not freeze. Do not use if it has been frozen. Keep away from the cooling element.
• Opened (In-Use) FlexPens: Once a FlexPen is opened and in use, it can be stored at room temperature (below 30°C / 86°F) for a maximum of 4 weeks (28 days). Do not refrigerate an in-use pen. Keep the pen cap on to protect it from light.
• Remove Needle After Use: Always remove the needle after each injection. This prevents air from entering the pen and insulin from leaking.

Potential Side Effects:

The most common and serious side effect of all insulins, including NOVOMIX-30, is hypoglycemia (low blood sugar). Symptoms can include:

• Sweating, cold sweats
• Shakiness, trembling
• Dizziness, lightheadedness, headache
• Confusion, blurred vision, slurred speech
• Anxiety, irritability, mood changes
• Rapid heartbeat
• Intense hunger

It is crucial to be prepared to treat hypoglycemia immediately by consuming a fast-acting source of sugar (e.g., glucose tablets, fruit juice, regular soda, or sugary candy).

Other common side effects may include:

• Injection site reactions: Pain, redness, itching, swelling, or bruising at the injection site. These are usually mild and temporary.
• Lipodystrophy and localized cutaneous amyloidosis: Skin changes (thickening, pits, or lumps) at injection sites if not rotated.
• Weight gain.
• Peripheral edema (swelling of hands and feet): This can occur when blood sugar control rapidly improves.
• Allergic reactions: Rare but serious generalized reactions (e.g., rash spreading over the whole body, shortness of breath, wheezing, swelling of face/lips/tongue, fast heartbeat, feeling faint) require immediate medical attention.
• Hypokalemia (low blood potassium): Insulin can cause a shift of potassium into cells.

Important Warnings and Precautions:

• Blood Glucose Monitoring: Regular and consistent monitoring of your blood glucose levels is absolutely essential to adjust insulin doses and prevent both hypoglycemia and hyperglycemia.
• Medical Supervision: Always use NOVOMIX-30 FlexPen under the guidance of a healthcare professional. Do not change your dose, timing, or type of insulin without consulting your doctor.
• Medication Interactions: Inform your doctor about all medications (prescription, over-the-counter, herbal supplements) you are taking, as many can affect blood sugar levels and may require insulin dose adjustments.
• Alcohol Consumption: Alcohol can significantly affect blood sugar levels and increase the risk of hypoglycemia. Discuss alcohol intake with your doctor.
• Driving/Operating Machinery: Be cautious if you experience symptoms of hypoglycemia or hyperglycemia, as your ability to concentrate and react may be impaired.
• Pregnancy and Breastfeeding: Consult your doctor if you are pregnant, planning to become pregnant, or breastfeeding, as insulin needs may change during these periods.
• Kidney or Liver Problems: Patients with kidney or liver impairment may require dose adjustments and closer monitoring.

NOVOMIX-30 FlexPen is an effective and convenient tool for managing diabetes, but its safe and successful use depends on strict adherence to medical advice, proper administration techniques, diligent blood glucose monitoring, and open communication with your healthcare provider.
