We’ve all experienced the discomfort of needles penetrating our skin at least once in our lives – it’s an inevitable part of any medical treatment or procedure. However, it doesn’t have to be a painful experience. Lidocaine and prilocaine cream, commonly known as numbing cream, can help alleviate the pain and discomfort caused by needles. But the question is – how long does it last?
For those who are new to the world of numbing creams, the duration of their effectiveness is crucial information. In some cases, patients may need to apply the cream well in advance to give it adequate time to take effect. But, just how long can you expect lidocaine and prilocaine cream to last? It’s essential to have a clear understanding of the length of time the cream will work effectively, so you can plan accordingly and ensure a pain-free experience.
Fortunately, we’ve got all the answers you need to help you prepare for your upcoming medical procedure. In this article, we’ll be exploring the duration of the effectiveness of lidocaine and prilocaine cream. We’ll cover how long it takes for the numbing agents to kick in, how long they last, and what factors contribute to their effectiveness. Whether you’re preparing for a surgical procedure or a simple blood test, you’ll want to read on to find out just how long you can expect to be pain-free.
The Longevity of Lidocaine and Prilocaine Cream
Lidocaine and prilocaine cream are topical anesthetics that offer temporary pain relief. They are commonly used for a range of medical procedures such as injections, minor skin surgeries, and laser treatments. The duration and efficacy of the cream depend on several factors, including the concentration of the active ingredients, the location of application, and the individual’s skin type.
- Concentration: The higher the concentration of lidocaine and prilocaine, the longer the duration of pain relief. A concentration of 5% usually lasts for approximately one hour, while a concentration of 2.5% lasts for 30 minutes.
- Location: The duration of pain relief depends on the location where the cream is applied. Areas with increased blood flow, such as the face, neck, and scalp, experience faster absorption and, subsequently, quicker onset of action and shorter duration of pain relief.
- Skin type: Individuals with dry or oily skin may find that the cream lasts longer or shorter than those with normal skin. This is because the barrier function of the skin determines the cream’s absorption rate and, ultimately, its duration of action.
It is important to note that while lidocaine and prilocaine cream offer temporary pain relief, they are not suitable for long-term use. Overuse can lead to skin irritation, allergic reactions, and in extreme cases, tissue damage. Therefore, it is recommended to follow the directions provided by a healthcare professional and use the cream as directed.
In conclusion, the longevity of lidocaine and prilocaine cream depends on several factors and can range from 30 minutes to an hour. It is essential to follow proper usage guidelines and avoid overuse to prevent any adverse effects.
How the Cream Works
The lidocaine and prilocaine cream, also known as EMLA cream, works by numbing the skin. The cream contains two local anesthetic agents, lidocaine and prilocaine, which when applied, penetrate the skin and block the nerve endings responsible for transmitting pain signals to the brain.
- Lidocaine: It works by blocking the sodium channels present in the nerve endings, thus preventing the transmission of pain signals.
- Prilocaine: It works by slowing down the movement of sodium ions across the nerve membrane, thereby reducing the flow of pain signals.
- Together, these agents provide an effective numbing effect, making the area numb to pain.
It takes approximately 60 minutes for EMLA cream to achieve maximum effect after application when used for topical anesthesia. The cream can be applied on various parts of the skin, including the genitals in male and female patients, and the perianal region in both genders.
The cream is used in many medical procedures, such as needle insertion, minor superficial surgical procedures, and superficial lesions removal. It is also used in cosmetic procedures like laser hair removal, dermal fillers injection, and tattoo removal.
| Application or Procedure | EMLA Cream Application Time |
|---|---|
| Needle Insertion | 60 minutes |
| Minor Superficial Surgical Procedures | 60 minutes |
| Superficial Lesions Removal | 60-120 minutes |
| Laser Hair Removal | 60-90 minutes |
| Dermal Fillers Injection | 30-60 minutes |
| Tattoo Removal | 60-120 minutes |
It is essential to follow the instructions given by the healthcare professional when using EMLA cream. Overuse of the cream can lead to systemic absorption of the cream, leading to side effects like methemoglobinemia, a rare but serious condition that affects the oxygen-carrying capacity of the blood.
EMLA cream has proven to be a safe and effective method for local anesthesia, providing pain relief during various procedures. When used appropriately, it allows patients to undergo procedures with minimal discomfort.

- Laser treatments: Dermatologists use lidocaine and prilocaine cream to numb the skin before performing laser treatments for hair removal or skin resurfacing.
- Minor surgical procedures: Lidocaine and prilocaine cream is commonly used to numb the skin before performing minor surgical procedures such as skin biopsies or freezing warts.
Proper application of the cream and dosage must be adhered to in order to prevent any possible complications.
