The FDA has issued a public health advisory on topical anesthetic creams, which are available as both over-the-counter (OTC) products and prescription medications. The advisory was issued based on two years of new reports of adverse events, including the death of two women. These adverse events were associated with using topical anesthetics before cosmetic procedures. The FDA is particularly concerned with their use before laser hair removal.

Lidocaine:

Lidocaine is a topical anesthetic that is applied to the skin. It is used for various purposes, including sore throat treatment and reducing gagging during X-rays. Another common use is to treat the nerve pain caused by herpes zoster and shingles. Currently, there are several topical anesthetics available on the market. Lidocaine is a member of the local anesthetics family. It works by blocking signals from nerve endings in the skin. Unlike traditional anesthetics, it does not induce unconsciousness.

Tetracaine:

Tetracaine is an amino-ester local anesthetic that is used for a variety of purposes. It is most commonly used as a topical ophthalmic anesthetic for procedures performed on the surface of the eye and ears. This agent has several indications and is relatively inexpensive compared to other local anesthetics.

When using this topical anesthetic, following the instructions for proper application is important. Avoid applying the medication to irritated, broken, or raw skin. It should also not be applied on areas that may come into contact with a baby’s mouth. Follow the label closely and seek medical advice if you experience any side effects.

Lidocaine hydrochloride ophthalmic gel:

Lidocaine hydrochloride ocular gel is a topical anesthetic used to numb the eyes during ocular surgery. This gel contains 35 mg of lidocaine per ml. It should be stored in the original carton away from light and disposed of after use. If left in the eyes for extended periods, lidocaine may result in corneal opacification and ulceration, which can cause vision loss. Also, lidocaine has been shown to have antibacterial and anti-fungal effects, which may play a supplementary role in treating surgical site infections.

Akten:

Akten is a prescription medicine approved by the Food and drug administration (FDA) on October 8, 2008. The medication works by stabilizing the neuronal membrane and inhibiting ionic fluxes necessary for nerve impulses. The treatment can last from five minutes to 30 minutes.
