Topical Local Anaesthetic for Numbing the Skin Before Procedures

EMLA Cream 5% Overview

EMLA Cream 5% is a topical local anaesthetic used to numb the skin before certain medical or cosmetic procedures. It contains a combination of lidocaine and prilocaine, which work together to temporarily block nerve signals in the skin, reducing pain and discomfort.

In the UK, EMLA is a pharmacy medicine (P) commonly used prior to injections, blood tests, cannulation, minor skin procedures and some cosmetic treatments.

Understanding Local Anaesthesia

Why topical anaesthetics are used

Many medical procedures involve needle insertion or superficial skin intervention, which can be uncomfortable or anxiety-provoking. Topical anaesthetics allow the skin to be numbed without injections, making procedures more tolerable.

By acting only at the site of application, topical anaesthetics provide targeted pain relief without affecting the rest of the body.

How numbing creams differ from painkillers

Oral painkillers reduce pain perception centrally, whereas local anaesthetics work by blocking nerve conduction at the skin level, preventing pain signals from reaching the brain in the first place.

What Is EMLA Cream?

EMLA Cream contains:

• Lidocaine
• Prilocaine

Both are amide-type local anaesthetics. When applied under an occlusive dressing, they penetrate the upper layers of the skin to provide effective surface anaesthesia.

The 5% concentration refers to the combined total of the two active ingredients.

How Does EMLA Cream Work?

Nerve signal blockade

Lidocaine and prilocaine block sodium channels in nerve membranes. This prevents nerve impulses from being transmitted, resulting in temporary numbness of the treated area.

Depth and duration of anaesthesia

EMLA provides surface anaesthesia that develops gradually. The depth and duration depend on:

• application time
• thickness of skin
• use of occlusion

Numbness typically lasts long enough for short procedures once the cream is removed.

What EMLA Helps With — and What It Does Not

What it helps with

EMLA Cream is used to numb the skin before:

• injections or vaccinations
• blood tests or cannula insertion
• minor dermatological procedures
• laser or cosmetic treatments
• superficial skin interventions

It is commonly used in both adults and children (age guidance applies).

What it does not treat

EMLA does not:

• provide long-term pain relief
• treat deep pain or inflammation
• work instantly
• replace injectable anaesthesia for major procedures

It is intended for temporary surface numbing only.

Who Is EMLA Cream For?

EMLA Cream may be suitable for:

• adults and children (as per product guidance)
• individuals undergoing minor procedures
• people with needle anxiety
• those requiring short-term local anaesthesia

A pharmacist can advise on appropriate use and suitability.

Who Should Avoid EMLA

EMLA Cream should not be used:

• on broken, inflamed or infected skin
• on mucous membranes unless directed
• in people with known allergy to local anaesthetics of the amide type
• in certain blood disorders such as methaemoglobinaemia, unless advised

Medical advice should be sought if unsure.

How to Use EMLA Cream

Apply a thick layer of cream to intact skin and cover with an occlusive dressing. The cream is usually left in place for at least 60 minutes before the procedure, depending on the area and purpose.

The cream should be removed completely before the procedure begins.

Safety, Warnings and Side Effects

EMLA is generally well tolerated when used correctly. Temporary skin reactions such as redness, paleness or mild swelling may occur at the application site.

Systemic side effects are rare when used as directed. Do not exceed recommended application time or amount.

When to Seek Medical Advice

Speak to a healthcare professional if:

• numbness lasts longer than expected
• skin irritation is severe or persistent
• the cream is accidentally swallowed
• symptoms of allergic reaction occur

Prompt assessment ensures safe use.

Use in Pregnancy and Breastfeeding

EMLA may be used during pregnancy or breastfeeding only on professional advice, as local anaesthetic exposure should be assessed individually.

How EMLA Compares to Other Anaesthetic Products

EMLA vs lidocaine sprays or gels

Sprays and gels act quickly but provide shallow numbing. EMLA penetrates deeper into the skin, making it more suitable for needle-related procedures.

EMLA vs injectable anaesthetics

Injectable anaesthetics provide deeper and longer-lasting anaesthesia but involve needles. EMLA offers a needle-free alternative for minor procedures.

EMLA Cream 5% Summary

EMLA Cream 5% (30 g) provides effective, temporary skin numbing using a combination of lidocaine and prilocaine. When applied correctly, it helps reduce pain and anxiety associated with minor medical and cosmetic procedures.

For safe and effective use, EMLA should always be used according to instructions or professional guidance.
