Final answer:

EMLA cream is a local anesthetic used to numb the skin before medical procedures. It does not contain procaine and can cause rare side effects such as methemoglobinemia. It should not be used on cracked or broken skin.

Step-by-step explanation:

EMLA cream is a local anesthetic and contains two active ingredients, lidocaine and prilocaine, both of which work to numb the skin by blocking nerve signals. It is commonly used to numb the skin before medical procedures such as injections or minor surgeries.

The cream does not contain procaine, which is a different local anesthetic. Methemoglobinemia, a condition where the blood is unable to transport oxygen effectively, can be a potential side effect of EMLA cream, but it is rare. The cream should not be used on cracked or broken skin, as it can be absorbed more readily and lead to potential side effects.

The 5% formulation of EMLA cream is used for specific indications, such as pediatric patients undergoing certain procedures. The cream works by causing local vasodilation, which helps to improve the absorption and effectiveness of the anesthetic agents.
