Managing your blood sugar is a vital part of staying healthy with diabetes. The Insulatard FlexPen 100 IU is a pre-filled, easy-to-use insulin pen designed to provide steady, long-acting control over your glucose levels throughout the day or night.
In this guide, we’ll explain how the Insulatard FlexPen works, its benefits, and how to use it safely as part of your daily routine.
What is Insulatard FlexPen Used For?
Insulatard is used to treat Diabetes Mellitus (both Type 1 and Type 2) in adults and children. It is a long-acting insulin that helps maintain a baseline level of insulin in the body.
The primary uses include:
- To control high blood sugar levels over an extended period.
- Preventing long-term diabetes complications like heart disease or nerve damage.
- Providing a “basal” insulin supply, often used alongside fast-acting insulin taken at mealtimes.
Ingredients in Insulatard
The active ingredient in Insulatard is Isophane (NPH) Insulin.
How Does Insulatard Work?
Insulatard is an intermediate-acting insulin. Once injected, it works by:
- Lowering Blood Sugar: It helps your cells take in sugar from the blood to use for energy.
- Liver Control: It tells your liver to stop producing extra sugar when your body doesn’t need it.
- Slow Release: Because it is an NPH insulin, it starts working about 1.5 hours after injection, reaches its peak effect between 4 and 12 hours, and lasts for about 24 hours.
Dosage and How to Take It
Note: Your doctor will determine your specific dose based on your weight and blood sugar levels.
- Check the Appearance: Insulatard is a cloudy (milky) suspension. You must gently rotate or move the pen up and down before use until the liquid is uniformly white and cloudy.
- Injection Sites: It is injected under the skin (subcutaneously), usually in the thigh, abdomen, or upper arm.
- Rotate Sites: Always change the exact spot where you inject within the same area to prevent skin lumps or thickening.
- Timing: It is often taken once or twice a day, depending on your medical plan.
Possible Side Effects
While Insulatard is highly effective, it is important to be aware of potential side effects.
Common side effects include:
- Hypoglycemia (Low Blood Sugar)
- Redness or swelling at the injection site.
- Weight Gain: A common effect of starting insulin therapy.
- Always keep a source of fast-acting sugar (like glucose tablets or fruit juice) nearby in case your blood sugar drops too low.
Frequently Asked Questions (FAQs)
1. Do I need to refrigerate my FlexPen?
Unused pens should be kept in the refrigerator ($2°C$ to $8°C$). Once you start using a pen, you can keep it at room temperature (below $30°C$) for up to 6 weeks. Never freeze insulin.
2. Can I share my FlexPen with someone else?
No. Even if the needle is changed, sharing an insulin pen can spread serious infections. The pen is for single-person use only.
3. Why is the insulin cloudy?
Insulatard is naturally cloudy because of the protamine added to make it last longer. If the liquid stays clear or has clumps after mixing, do not use it.
