It is becoming more and more common for doctors and their patients to apply numbing cream for injections. Numbing cream for injections is used to reduce or eliminate the needle stick pain. There are several numbing cream for injection products available to both clinicians and their patients.
Needle sticks can be painful. Many physicians and their patients are using numbing cream for injections to reduce that pain.

First it can be helpful to understand what causes the fear and pain from injections and how using numbing cream for injections can help you ease the pain and anxiety.
Why Use Numbing Cream for Injections?
The condition of being very heightened about needles (“needle phobia”) is known as trypanophobia. It is known to affect at least 10% of the population. It is sometimes caused by early childhood painful experiences. It can also be passed down from one generation to another. The response to trypanophobia that causes dizziness and other related symptoms is called a vaso-vagal response. This response includes, initially high heart rate and blood pressure, followed by a resultant drop in blood pressure and heart rate. This secondary affect can also lead to extreme dizziness and fainting.
The pain caused by the needle puncturing the skin is caused when the high voltage sodium ion gate is activated and the nerve depolarizes, leading to the conduction of sensory neuron pain signals. The API in most numbing creams for injections blocks the sodium channel from being activated, which leads to a reduction or elimination of the pain signals.
An effective numbing cream for injections includes a delivery system that allows the API to enter the skin rapidly where it can perform its job. Not all numbing creams include ingredients that make the skin temporarily more permeable. A list of some of those ingredients that help this process are:
- Propylene glycol
- isopropyl myristate
Those numbing creams that include these ingredients are designed to permeate the skin more rapidly and completely. This process can make the numbing cream more effective and faster.
NeuroMed 7 is a numbing cream that includes penetration enhancer technology that is designed for a more rapid and effective permeation of the API lidocaine to enter the skin and block the nerve impulses that signal pain.
