Lidocaine/Prilocaine Cream

What is Lidocaine/Prilocaine Cream?

Lidocaine/Prilocaine cream is a local anaesthetic.  This means that you apply it to the skin and it will numb the area. This makes it an effective treatment for premature ejaculation. The reduced sensation into the skin of the penis, should help to reduce sexual stimulation and therefore delay ejaculation. 

How does Lidocaine/Prilocaine Cream work?

Lidocaine/Prilocaine (EMLA) cream works by numbing the local area to which it is applied, by affecting the flow of sodium into the neurons. It works within 5-10 minutes of application and lasts 15-20 minutes.

Active ingredients

Lidocaine/Prilocaine Cream (EMLA) contains the following active ingredients:

• 25mg lidocaine
• 25mg prilocaine

Both lidocaine and prilocaine are anaesthetics that help to numb the skin. 

Inactive ingredients

Lidocaine/Prilocaine Cream also contains the following inactive ingredients: polyoxyethylene fatty acid esters (as emulsifiers), carboxypolymethylene (as a thickening agent), sodium hydroxide to adjust to a pH approximating 9, and purified water to 1 gram. 

Please note that the inactive ingredients may vary between manufacturers. The ingredients listed above are found in the EMLA brand of Lidocaine/Prilocaine Cream.

Dosage

A small amount of EMLA cream may be applied to the penis 5 minutes before intercourse. For external use only. Do not apply to open wounds, near the eyes or ears. Squeeze a narrow strip from the tube. A small amount will be systemically absorbed, but in studies this was not enough to be significant.

How should I use Lidocaine/Prilocaine Cream?
