Butterfly Needle Vs Regular Needle: A Detailed Comparison

When it comes to drawing blood or starting an IV, you have two main options for needles: butterfly needles and regular needles. If you’re wondering about the key differences and which one is better for certain situations, you’ve come to the right place.

If you’re short on time, here’s a quick answer: Butterfly needles have flexible tubing which allows for more versatile positioning and movement. Regular needles don’t have tubing so they are simpler to use. Butterfly needles cause less pain and scarring.

Regular needles are cheaper and may be preferred for blood draws.

What is a Butterfly Needle?

A butterfly needle, also known as a winged infusion set or scalp vein set, is a specialized type of needle used for venipuncture procedures. It is named after its unique shape, resembling the wings of a butterfly.

This type of needle is commonly used for drawing blood or administering medication, particularly in cases where the patient’s veins are difficult to access or are fragile.

Definition and Key Features

A butterfly needle consists of a plastic hub with two flexible “wings” on either side, attached to a thin hollow needle. The needle is typically shorter and smaller in gauge compared to a regular needle, making it less painful for the patient.

The wings on the hub provide stability and control during the procedure, allowing for precise insertion and maneuverability within the vein.

One key feature of a butterfly needle is its ability to create a shallow angle of entry into the vein, which reduces the risk of puncturing through the opposite wall of the vein. This is particularly important when dealing with delicate veins, such as those in pediatric or elderly patients.

Pros of Butterfly Needles

  • Less Painful: The smaller gauge and shorter length of the needle make butterfly needles less painful for patients, especially those with sensitive or fragile veins.
  • Increased Precision: The wings on the hub provide better control and stability, allowing for precise insertion and maneuverability within the vein.
  • Reduced Risk of Hematomas: The shallow angle of entry reduces the risk of puncturing through the opposite wall of the vein, minimizing the likelihood of hematoma formation.
  • Improved Blood Flow: Butterfly needles are designed to allow for a smoother and faster flow of blood, making the process more efficient.

Cons of Butterfly Needles

  • Higher Cost: Butterfly needles are generally more expensive compared to regular needles, which can be a limiting factor in healthcare settings with tight budgets.
  • Not Suitable for High-Pressure Injections: Due to their smaller gauge, butterfly needles are not recommended for high-pressure injections or when large volumes of medication need to be administered quickly.
  • Increased Risk of Infiltration: The smaller needle size and flexibility of the wings can increase the risk of infiltration, where fluid leaks into the surrounding tissue rather than entering the vein.

It is important to note that the choice between a butterfly needle and a regular needle depends on the specific needs of the patient and the procedure being performed. Healthcare professionals should consider factors such as vein condition, patient comfort, and the type of medication or blood sample required before deciding on the appropriate needle to use.

What is a Regular Needle?

A regular needle, also known as a standard or conventional needle, is the most commonly used type of needle in medical procedures, including blood draws and injections. It is a thin, hollow tube made of stainless steel or plastic, with a sharp beveled tip.

Definition and Key Features

The regular needle is typically available in various lengths and gauges, with the gauge referring to the diameter of the needle. The smaller the gauge number, the larger the diameter of the needle. For example, a 22-gauge needle is thicker than a 25-gauge needle.

Regular needles are designed to puncture the skin and access blood vessels or deliver medications. They are commonly used for routine blood tests, vaccinations, and administering medications intramuscularly or subcutaneously.

Pros of Regular Needles

Regular needles have several advantages that make them the preferred choice in many medical settings. First, they are widely available and cost-effective, making them accessible for healthcare providers and patients alike.

Second, regular needles are versatile and can be used for a variety of purposes, from drawing blood to administering medications. They are suitable for most patients, regardless of age, size, or medical condition.

Furthermore, regular needles are relatively easy to use and handle, which allows healthcare professionals to perform procedures efficiently and with minimal discomfort for the patient.

Cons of Regular Needles

Despite their widespread use, regular needles do have some limitations. One of the main drawbacks is the potential for pain and discomfort during the insertion and removal of the needle. This can be particularly concerning for individuals who have a fear of needles or experience anxiety during medical procedures.

Additionally, regular needles may cause bruising or hematoma formation at the injection site, especially if the needle is not inserted correctly or too much pressure is applied.

Regular needles also carry a small risk of accidental needlestick injuries for healthcare providers, which can lead to the transmission of bloodborne pathogens.

It is important to note that while regular needles are suitable for most medical procedures, there may be specific cases where alternative needle types, such as butterfly needles, are preferred for their unique features and benefits.

Butterfly Needle vs Regular Needle: Key Differences

Pain Levels

One of the key differences between butterfly needles and regular needles is the level of pain experienced during the insertion. Butterfly needles, also known as winged infusion sets, are designed with a smaller gauge and a shorter length than regular needles.

This makes them less painful to use, especially for individuals with a fear of needles or those with sensitive skin. Regular needles, on the other hand, can cause more discomfort due to their larger gauge and longer length.


When it comes to scarring, butterfly needles have an advantage over regular needles. Due to their smaller size, butterfly needles typically leave behind smaller puncture wounds, resulting in less noticeable scarring.

Regular needles, with their larger gauge and longer length, can cause larger puncture wounds that may result in more visible scars. However, it’s important to note that scarring can vary depending on factors such as individual skin type and proper wound care.


In terms of cost, regular needles are generally more affordable than butterfly needles. Regular needles are commonly used in medical settings and are available in bulk at a lower cost. Butterfly needles, being more specialized, can be more expensive to purchase.

However, it’s important to consider that the cost of the needle itself is just one aspect. Other factors such as the overall procedure cost and potential complications should also be taken into account.

Ease of Use

Butterfly needles are often preferred by healthcare professionals and individuals who self-administer injections due to their ease of use. The wings on the needle make it easier to control and stabilize during the insertion process.

Regular needles, while still relatively simple to use, may require a bit more skill and precision to ensure a successful injection. It’s important to note that proper training and technique are crucial for both types of needles to minimize any potential risks.

Applications and Situations

Both butterfly needles and regular needles have their own specific applications and situations in which they are preferred. Butterfly needles are commonly used for individuals with fragile veins, such as pediatric patients or those with difficult venous access.

They are also favored for drawing blood samples for laboratory testing. Regular needles, on the other hand, are widely used for various medical procedures, including vaccinations, intramuscular injections, and other routine medical interventions.

How to Choose Between the Two

Consider the Procedure

When choosing between a butterfly needle and a regular needle, it is important to consider the specific procedure being performed. Butterfly needles, also known as winged infusion sets, are typically used for procedures that require smaller gauge needles or for patients with delicate veins, such as when drawing blood for laboratory tests or administering medications.

On the other hand, regular needles, also known as hypodermic needles, are commonly used for procedures that require larger gauge needles or for patients with more robust veins, such as when administering intravenous fluids or performing vaccinations.

Assess the Patient’s Needs

The needs and comfort of the patient should also be taken into consideration when choosing between a butterfly needle and a regular needle. Some patients may have a fear or phobia of needles and may prefer the use of a butterfly needle, as they are typically smaller and cause less discomfort during insertion.

Additionally, patients with fragile or sensitive veins may benefit from the use of a butterfly needle, as they can minimize the risk of bruising or damage to the veins. However, it is important to note that some patients may have a preference for regular needles due to their familiarity or past positive experiences.

Evaluate Your Skills and Preferences

Another factor to consider when choosing between a butterfly needle and a regular needle is your own skills and preferences as a healthcare professional. If you are highly skilled and comfortable with using butterfly needles, you may choose to use them for a wider range of procedures.

However, if you have limited experience or are not as confident in using butterfly needles, you may prefer to stick with regular needles that you are more familiar with. It is important to choose the option that you are most comfortable and confident in using, as this will help ensure the safety and success of the procedure.


In summary, butterfly needles and regular needles both have their pros and cons. Butterfly needles tend to cause less pain and scarring due to their flexible tubing but they cost more. Regular needles are simpler to use and cheaper but may be more painful.

When choosing between the two, consider factors like the procedure, patient needs, your own skills, and personal preferences. With the information in this guide, you should now be able to select the right needle for your next blood draw or IV.
