Levemir Flextouch vs Flexpen
Introduction
For patients with diabetes mellitus, certain insulin analogs that mimic the body's natural insulin secretion can help in managing blood sugar levels and keeping symptoms under control. Levemir Flextouch and Flexpen are two such insulin delivery devices that doctors often prescribe to diabetics. They each allow for different levels of dosage customization, but both have significant effects in helping patients manage their diabetes. Levemir Flextouch is a disposable dial-a-dose insulin pen that allows you to administer your insulin without having to handle a vial or syringe, making it more convenient and discrete. On the other hand, Flexpen is another type of pre-filled, dial-a-dose injection device designed for ease of use by even people who are visually impaired or have dexterity issues as it includes audible clicks when doses are adjusted.
What is Levemir Flextouch?
Insulin detemir (the generic name for Levemir) was a significant advancement in the world of diabetes management upon its introduction. It is a long-acting insulin analog that mimics the body's natural release of insulin, providing steady coverage over a 24-hour period to help control blood sugar levels. The FDA approved Insulin detemir first in 2005. Levemir works by allowing glucose to enter cells, thereby reducing high levels of glucose in the bloodstream. Two delivery devices are available: the FlexTouch and the FlexPen.
The Levemir Flextouch has distinct advantages over its precursor, the Flexpen; one being it doesn't require any pushing force when injecting at all dose steps due to spring-loaded technology which makes injections more comfortable for patients with dexterity or strength issues. Furthermore, both have minor side effects including reactions at injection site or weight gain but are known to be less than other types of insulins that may cause hypoglycemia if not balanced correctly with food intake and exercise.
What conditions is Levemir Flextouch approved to treat?
Levemir Flextouch is approved for the treatment of different variations of diabetes:
- Type 1 diabetes, in which insulin production is insufficient or non-existent
- Type 2 diabetes, where the body's cells become resistant to insulin The Levemir FlexTouch device aids in providing accurate and convenient dosage administration for these patients.
How does Levemir Flextouch help with these illnesses?
Levemir FlexTouch helps manage diabetes by slowly releasing insulin into the bloodstream, mimicking the steady release of insulin that a healthy pancreas would provide. This slow-release feature helps to maintain stable blood sugar levels throughout the day and night. Insulin is a hormone that allows cells in your body to take in glucose from your bloodstream. Glucose is used as energy for cell function, but when there's not enough insulin—or if it’s not being used properly—glucose can build up in your blood instead of being absorbed by cells. It's thought that individuals with diabetes have problems managing their blood glucose levels due to either insufficient production or ineffective use of insulin. Therefore, by providing a slow and steady supply of insulin, Levemir FlexTouch can limit the negative effects of uncontrolled diabetes and help patients manage their condition more effectively.
What is Flexpen?
Flexpen is a brand name for Novo Nordisk's pre-filled, dial-a-dose insulin pen. It allows users to inject their required dose of insulin without the need for vials and syringes. The Flexpen contains 300 units of insulin, and doses can be adjusted in one-unit increments up to 60 units per injection. First introduced in the mid-2000s, the Flexpen has been designed with convenience and ease-of-use in mind - its simple design means that patients have less steps to follow when preparing their injections.
In contrast to Levemir Flextouch which delivers a long-acting form of insulin (Insulin detemir), Flexpen can deliver either short or long acting insulins depending on the specific type you are prescribed. This makes it versatile for managing both baseline (fasting) blood glucose levels as well as post-meal spikes.
While not causing sedation or sexual dysfunction like some SSRIs such as Prozac do, potential side effects from using any type of insulin delivery device include hypoglycemia (low blood sugar), allergic reactions at the injection site, lipodystrophy (changes in fat tissue at injection sites), weight gain, and edema (fluid build-up). However, these risks are generally outweighed by the benefits of maintaining good glycemic control.
What conditions is Flexpen approved to treat?
The FlexPen is sought after as a delivery method for insulin, including but not limited to:
- Type 1 diabetes, where it's used to supplement the body's lack of natural insulin.
- Type 2 diabetes, where it helps control blood sugar levels when oral medication and lifestyle changes aren't enough.
How does Flexpen help with these illnesses?
Insulin is a hormone that plays key roles in regulating blood sugar levels and the metabolism of carbohydrates, fats, and proteins. In patients with diabetes mellitus, insulin production by the pancreas is either insufficient or the body's cells are resistant to its effects. Flexpen provides exogenous insulin to help regulate these processes in diabetic individuals. It operates by mimicking the action of naturally produced insulin, thereby helping to manage blood glucose levels throughout the day - crucial for patients with diabetes. Unlike Levemir Flextouch which has a specific duration of action per dose, Flexpen offers flexibility as it can be adjusted according to an individual's lifestyle or meal plans making it suitable for those who require personalized treatment regimens. While both provide essential control over this chronic condition, Flexpen might be preferred when more tailored therapy is required.
How effective are both Levemir Flextouch and Flexpen?
Both Levemir FlexTouch and the original FlexPen have established histories of success in delivering insulin detemir for patients with diabetes, and they were initially approved by the FDA within a decade of each other. Since they both deliver the same medication but via different device designs, they may be chosen under varying patient circumstances.
The effectiveness of Levemir delivered using either system was directly studied in multiple clinical trials; both devices exhibited equivalent efficacy in maintaining glycemic control as well as similar safety profiles. In these studies, none of the different metrics used to measure efficacy in managing blood glucose levels differed between patients receiving their Levemir via the FlexTouch or those using a FlexPen.
A review conducted on insulin delivery systems demonstrated that newer devices like the Flextouch are designed to make it easier for patients to administer their insulin treatments correctly and consistently. The Flextouch is reported to require less forceful pressure during injection compared to its predecessor, making it potentially more comfortable for certain populations such as elderly or arthritic patients.
While data confirming its preference over traditional pen injectors is not yet extensive due to its relatively recent introduction into medical practice, early results suggest Flextouch may offer some advantages over earlier models such as ease-of-use and comfort during injection.
Nonetheless, due to unique characteristics relating to individual patient needs (e.g., needle phobia), preferences (comfortability) and abilities (manual dexterity), one model could end up being preferred over another despite similar overall function.
At what dose is Levemir Flextouch typically prescribed?
Dosages of Levemir Flextouch and Flexpen are typically tailored to individual patient needs, but they generally range from 0.1-0.2 units/kg/day for treating type 1 or type 2 diabetes in adults. Children and adolescents may be started on a lower dose based on their body weight, but this should always be under the supervision of a healthcare provider. The dosage can then be adjusted after a few weeks if necessary, according to blood glucose control. It is important that dosages are not changed without consulting your doctor first as both types of insulin pens contain long-acting insulins that work over several hours to help control blood sugar levels throughout the day.

At what dose is Flexpen typically prescribed?
The Flexpen for insulin delivery is typically started with the dosage recommended by a healthcare provider, based on the patient's individual needs. This dosage can then be adjusted in increments as determined by blood glucose levels and doctor recommendations. The maximum dose varies widely among individuals due to factors such as weight, diet, exercise level, and other concurrent medications. It should be noted that doses often need to be divided into two or more separate injections throughout the day depending on your body’s insulin requirements— these are not usually spaced out but rather timed around meals or bedtime. If there is no significant response in blood glucose control after a certain period of consistent usage at an initial dose, your doctor might consider adjusting your regimen further.
What are the most common side effects for Levemir Flextouch?
Common side effects of Levemir Flextouch may include:
- Reactions at the injection site such as redness, swelling or itching
- Weight gain
- Headache
- Back pain
- Stomach pain
- Flu-like symptoms (such as fever, chills and sore throat)
- Cold symptoms like runny or stuffy nose, sneezing, sinus pain, cough
It's important to note that both Levemir Flextouch and Flexpen contain the same medication - insulin detemir. The difference between them lies in their delivery mechanism rather than in the medicine itself. The side effects are therefore similar for both devices. If you experience any severe or persistent side effects while using either device, seek medical attention promptly.
Are there any potential serious side effects for Levemir Flextouch?
While Levemir Flextouch and Flexpen are delivery mechanisms for the same insulin medication, there can be distinct considerations when using either. Some possible side effects that might arise include:
- Signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue or throat.
- Low potassium level in the body - leg cramps, constipation, irregular heartbeats, fluttering in your chest, increased thirst or urination,numbness or tingling
- Hypoglycemia (low blood sugar) symptoms such as headache,dizziness,trembling,sweating,hungry,fatigue .
- Lipodystrophy (skin changes where the medicine is injected)
- Swelling in your hands and feet
- Rapid weight gain If you experience any of these potential side effects while using either device to administer insulin therapy it's crucial to seek immediate medical attention.
What are the most common side effects for Flexpen?
Flexpen, a device used for insulin delivery, can cause the following potential side effects:
- Hypoglycemia (low blood sugar), which may lead to sweating, trembling, dizziness and even confusion if severe.
- Injection site reactions such as redness, swelling or itching.
- Weight gain due to an increased appetite
- Mild rash or skin changes around the injection area
- Fluid retention causing swelling in parts of your body These are not all possible side effects and others may occur. Always consult with your healthcare provider about any concerns you have about a medication.
Are there any potential serious side effects for Flexpen?
While Flexpen is generally safe to use, some users may experience severe side effects. If you notice any of the following symptoms after using Flexpen, seek medical attention immediately:
- Signs of a serious allergic reaction: hives; difficulty breathing; swelling in your face or throat
- Low potassium level: leg cramps, constipation, irregular heartbeats
- Hypoglycemia (Low blood sugar): dizziness and lightheadedness, sudden sweating or shaking, fast heartbeat
- Hyperglycemia (High blood sugar): frequent urination, increased thirst and hunger
- Lipodystrophy (changes in skin at the site of injection)
Remember that it's important to rotate your injection sites with each dose to reduce your risk of developing these changes. Always communicate any concerns or adverse reactions to your healthcare provider.
Contraindications for Levemir Flextouch and Flexpen?
Levemir Flextouch and Flexpen, like all insulin products, may cause blood sugar levels to dip too low (hypoglycemia). If you notice signs of hypoglycemia such as dizziness, confusion, irritability or rapid heartbeat, please seek immediate medical attention.
Neither Levemir Flextouch nor Flexpen should be used if you are allergic to any of its ingredients or if you're experiencing an episode of hypoglycemia. Always disclose your medication schedule with your physician; some medications might affect how insulin works which could require adjustments in the dosage.
In addition to this, certain conditions can change your insulin needs including pregnancy, illness or a change in diet and exercise routine. In these situations it is crucial that you consult with your healthcare provider for proper management.
How much do Levemir Flextouch and Flexpen cost?
For the brand name versions of these insulin pens:
- The price of 5 Levemir Flextouch pens (3 mL each) averages around $600, which works out to approximately $40/day, depending on your dose.
- The price for 5 Flexpen devices (3mL each) is about $560, corresponding to roughly a cost per day of $37.
Thus, if you are in the higher dosage range for insulin therapy (i.e., requiring more than one injection per day), then brand-name Flexpen might be less expensive on a per-day treatment basis. However, remember that cost should not be the primary consideration when deciding between these two options.
As far as generic versions go:
Unfortunately, there's no direct equivalent for either Levemir Flextouch or Novo Nordisk's FlexPen since they're both proprietary delivery systems for their respective insulins. Therefore we can't provide an apples-to-apples comparison like we could with Prozac and Wellbutrin. That said it’s always wise to consult your healthcare provider and pharmacist regarding lower-cost alternatives or potential patient assistance programs offered by manufacturers.
Popularity of Levemir Flextouch and Flexpen
Insulin detemir, available under the brand name Levemir in both Flextouch and Flexpen forms, is widely used for managing blood sugar levels in people with diabetes.
In 2020, about 5 million prescriptions were filled for Levemir products in the US. This accounts for approximately 10% of overall long-acting insulin prescriptions. Both the Flextouch and Flexpen versions have been popular among patients due to their user-friendly design.
The Levemir Flextouch was introduced after the original Flexpen model as an improved version designed to make administering insulin easier and more convenient. It features a no push-button extension during injection, reducing discomfort when delivering high-dose injections compared to the older Flexpen model. Despite this newer innovation, however, both versions remain heavily prescribed across America with relatively steady usage over recent years.
Conclusion
Both Levemir FlexTouch and FlexPen are well-established insulin delivery devices for patients with diabetes, and have been shown to improve blood glucose control effectively. The choice between the two is often down to personal preference, since their mechanisms of action are similar, delivering long-acting insulin detemir subcutaneously.
Levemir FlexTouch has a spring-loaded mechanism which means it requires less force to deliver the dose, making it potentially easier for individuals with limited strength or dexterity. On the other hand, Levemir FlexPen may be more familiar as it's been available on the market for longer.
Both devices come pre-filled with insulin and offer a dial-up dose selector allowing doses from 1 up to 60 units in single unit increments. They do not require refrigeration after first use but must be discarded after 42 days even if they still contain insulin.
The side effect profile is essentially identical between the two devices as they deliver the same medication. Users should monitor their blood glucose levels regularly - especially when starting treatment or changing dosages - and contact a healthcare provider immediately if they experience symptoms of high or low blood sugar.
