Flu Shot Season: Using Numbing Cream to Make Injections Easier for Needle-Anxious Patients
As flu shot season returns, millions of people roll up their sleeves to protect themselves and those around them. While the injection itself only takes a few seconds, it’s often enough to make many people feel nervous for the prick–especially those with needle anxiety.
Whether you’ve avoided getting your annual flu vaccine because you're worried about the pain or simply want a more comfortable experience, you're not alone. Fear of needles is one of the most common reasons people postpone or skip recommended vaccinations, even when they understand their importance.
Fortunately, there are several ways to make the experience easier. From relaxation techniques to using a numbing cream for injections, a little preparation before your appointment can help reduce discomfort and make getting your flu shot feel far less intimidating.
In this guide, we'll explain how topical lidocaine works, when to apply numbing cream before an injection, and other practical tips to help make flu shots—and other routine vaccinations—more comfortable.
Why Do Injections Hurt?
Although injections are quick, they still involve a needle passing through the skin and stimulating pain receptors.
How much discomfort you experience depends on several factors, including:
- Needle size
- Injection location
- Medication being administered
- Individual pain tolerance
- Anxiety levels
For many people, anticipation contributes just as much to the experience of the injection itself.
Understanding Needle Anxiety
Feeling nervous before a shot is common. In fact, many adults continue to experience needle anxiety long after childhood.
Symptoms often include:
- Increased heart rate
- Sweaty palms
- Muscle tension
- Dizziness
- Feeling faint
- Avoiding medical appointments altogether
Research has shown that anxiety can actually increase the perception of pain, making injections feel more uncomfortable than they otherwise would.
The good news is that preparing ahead of time can help reduce both anxiety and discomfort.
Does Numbing Cream Work for Injections?
Yes, using a numbing cream before injections works by temporarily blocking pain signals in the skin before the needle enters the body. While it doesn’t eliminate the sensation of pressure or the medication itself, it significantly reduces pain associated with needles entering the skin.
Topical anesthetics are commonly used before:
- Flu shots
- Routine vaccinations
- Vitamin injections
- Cosmetic injectables
- Blood draws
- Allergy shots
How Does Topical Lidocaine Work?
Most topical lidocaine for injections works by temporarily blocking sodium channels within nerve endings near the skin's surface. This reduces the ability of nerves to transmit pain signals to the brain.
Because lidocaine works only where it's applied, the numbing effect remains localized to the treatment area.
Once the lidocaine wears off, normal sensation gradually returns.
When Should You Apply Numbing Cream Before an Injection?
Timing is important. For best results, Zensa Numbing Cream should be applied approximately 15-20 minutes before your injection, allowing enough time for the lidocaine to properly numb the skin before your appointment.
For optimal results:
- Clean the injection site thoroughly with an alcohol swab
- Apply a thick, visible layer of numbing cream to the area
- Cover with an occlusive dressing, such as Tegaderm or plastic cling wrap, for maximum absorption
- Remove the wrap, gently dab away excess cream using sterile gauze

Other Ways to Make Shots Hurt Less
Numbing cream is just one part of creating a more comfortable flu shot experience.
Additional strategies include:
Stay Relaxed
Tensing your muscles can make injections feel more uncomfortable. Slow, steady breathing helps reduce muscle tension. Many people find it helpful to meditate or think of peaceful scenarios to help ease muscle tension and relax the body.
Don't Watch the Needle
Many people find that looking away during the injection helps reduce anxiety.
Stay Hydrated
Proper hydration supports healthy circulation and may help you feel better after your appointment.
Let Your Provider Know
If you have significant needle anxiety, tell your healthcare provider before the injection. They’re experienced in helping needle-anxious patients feel more comfortable.
Choosing the Right Numbing Cream for Injections
Not every numbing product is formulated the same way.
When selecting a numbing cream for shots, consider:
- Lidocaine concentration
- Recommended application time
- Intended use
- Skin sensitivity
- Formulation and ingredients
Zensa Numbing Cream contains 5% lidocaine, the maximum strength available without a prescription, to temporarily numb the skin before injections.
Its water-based, pH-balanced formula is designed to absorb efficiently without leaving a greasy residue, making it a convenient option before medical appointments.
