LMX4 Lidocaine 4% Cream is a local anesthetic that eases pain when inserting a needle into a vein or having a cannula. It is ideal for those who struggle to have blood tests where a needle is used to take blood or those who need to have painful topical skin treatments and need reliable pain relief. LMX4 contains lidocaine, a local anesthetic. This means that LMX4 works by numbing the area of the body to which it is applied, easing pain caused by inserting a needle into a vein or pain caused by topical treatments applied to the skin.
