What is Lidocaine? How does Lidocaine Work?

Lidocaine is a type of anesthetic, and can temporarily limit sensations or pain. Topical lidocaine products can be bought over the counter at various strengths or concentrations. 

Lidocaine works by temporarily blocking the skin’s nerve endings to limit sensations. Therefore, individuals can use lidocaine to relieve burning or itching, such as the sensations caused by nerve pain, sore muscles, sunburn, insect bites, and other minor ailments. However, lidocaine will not treat the underlying condition that causes the unwanted pain or itchiness.

What are the Differences Between Lidocaine Cream vs Lidocaine Ointment vs Lidocaine Patch vs Lidocaine Spray vs Lidocaine Roll On?

Lidocaine is available in a variety of dosage forms (applicator types). These products contain lidocaine for application to the affected skin (topical). These products all relieve pain or itching directly at the application site; however, each product has some critical differences. 


Before using any of these products, it is essential to have clean and dry hands and skin. Do not apply any lidocaine product on an open wound, severe burn, and cracked or inflamed skin without a physician's order. 

Lidocaine Cream

Lidocaine cream is applied by rubbing the cream onto the treatment site. Lidocaine cream is a water-based formulation; therefore, it has a semi-thick consistency and is easy to apply and massage into the skin. Its effects can be felt within 30 minutes and last up to approximately 3 hours.

Lidocaine Ointment

Similarly, lidocaine ointment is applied by rubbing the ointment onto the treatment site. However, ointments are oil-based; therefore, lidocaine ointment has a thick, greasy consistency. Lidocaine ointments will stay on the skin for an extended period and can provide added barrier protection for sensitive sites.


Lidocaine Patches

Lidocaine patches are applied to the site of the pain or itching. The lidocaine patch has an adhesive that helps it stick and it will slowly deliver the medicine over an extended period. Lidocaine patches should not be used on open wounds or along with a heating pad, as the heat will cause more medicine to absorb into the skin. Additionally, patches should stay dry before and during use. Patches are an excellent alternative for areas that are hard to reach with  creams or ointments, such as an area usually covered with clothing. They can be used for 8 to 12 hours per application (depending on the specific product) or up to 3 times daily. 


Lidocaine Spray

Lidocaine spray is sprayed onto the skin at the treatment site. A lidocaine spray may be preferred if the site is painful to the touch, because a spray is a gentle mist. Lidocaine will begin working quickly. 


Lidocaine Roll On

Lidocaine roll on is applied directly onto the treatment area using the rolling applicator. The roll on formulation is a no-mess alternative to some of the other formulations.

Which Topical Formulation of Lidocaine is the Strongest: Lidocaine Patch, Lidocaine Ointment, Lidocaine Cream, Lidocaine Roll On, or Lidocaine Spray?

All lidocaine formulations have similar strengths, and offer similar relief of pain or itchiness. Most over-the-counter lidocaine products will have a strength of 4% to 5%. This indicates the amount of the active ingredient in the product, or in this case, the amount of analgesic causing relief. Lidocaine creams, lidocaine ointments, lidocaine roll ons, and lidocaine sprays can all be purchased without a prescription up to 5% strength. Lidocaine patches can be purchased up to 4% strength without a prescription. It should be noted that lidocaine patches typically have longer-lasting effects of up to 12 hours due to the lidocaine’s slower (sustained or extended) release through the patch.

Can I Use Lidocaine Products Together?

No, using any two lidocaine products together - whether a lidocaine patch, lidocaine cream, lidocaine ointment, lidocaine spray, or lidocaine roll on - is not recommended. Although each product is safe to use, the combination of lidocaine products together may increase the risk of too much active ingredient (lidocaine) at one time which could have adverse side effects.
