Why is Emla prescribed?

Prilocaine and Lidocaine (Emla) cream is prescribed to induce analgesia (inability to feel pain) before surgery or medical procedures. It can also be used to numb an area before administering a Lidocaine injection for stronger pain relief.

What does it do?

Emla cream is used on normal intact skin or mucous membranes of the genitals. Emla belongs to a drug class called local anesthetics and it works by inhibiting nerve signals and causing temporary numbness in the area being treated.

How should I apply it?

Emla and its generic equivalents are currently available as a 2.5/2.5% cream which is intended to be applied externally onto the skin.

Wash your hands thoroughly before and after handling the medication. Apply the smallest amount possible for numbing the skin to prevent absorbing too much of the medication. Do not apply Emla cream onto cuts or irritated skin. Do not use bandages or coverings to cover the area unless instructed by your doctor. Always follow your doctor’s instructions when using the medication.

The dosage strength depends on every patient’s condition and the doctor’s prescription. It is imperative that you do not self-medicate and only use this drug after consulting with your doctor or pharmacist to determine the best dosage and dosing schedule for the treatment of your condition.

What if I missed a dose?

The desired effects of prescribed medications will only be achieved if used properly. As much as possible, strictly follow your doctor’s prescribed dosing schedule. If you miss a dose, consult your doctor for instructions.

What are the special precautions before applying Emla?

Inform your doctor about all the medications you are taking, your current and previous medical history, and any allergic reactions to Emla or any other ingredients included in the manufacture of this medication.

Exercise caution when using Emla cream in elderly patients to prevent exacerbations of the effects of the medication, leading to symptoms such as dizziness.
