Wouldnt it be nice to avoid those intolerable pains and getting what should be done,
done without that hassle sensation? Luckily, Dr. Numb (Numbing Cream/ Topical
Anesthetic Cream) offers that comfort youve been looking for. Think about it, why
fell pain when you can go for the painless way? Think Smart! Choose the smarter
way.
Dr. Numb contains lidocaine, a substance that has been used for many years as
anesthetics in medical and dental offices. Dr. Numb contains more of a pure form of
lidocaine which acts as the numbing anesthetic cream or topical anesthetics for the
skin. The purity is very important, because not all lidocaine is manufactured and
refined as Dr. Numb has been. Pain is caused by the stimulation of pain receptors at
the ends of the nerves. The stimulation causes sodium to enter the nerve ending,
which causes an electrical signal to build up in the nerve. When this electrical signal
is big enough, it passes along the nerve to the brain, where the signal is interpreted as
pain. Dr. Numb works by temporarily blocking this pathway of pain signals along
nerves. Dr. Numb numbing anesthetic cream does this by stopping the sodium
entering the nerve ending at the site of the pain. This prevents an electrical signal
building up and passing along the nerve fibers to the brain.
A lot of options to deliver anesthesia have developed over the previous several
decades. Administration of topical anesthetics to administer pain associated with
procedures such as laceration repair may avoid the need for infiltrative local
anesthesia injections and associated pain from the injections. Topical anesthesia also
prevents the risk of wound margin distortion that exists with infiltrative injection
administration. Many dosage forms available (eg, gels, sprays, creams, ointments,
patches) and provide the clinician with precise options for application under various
circumstances.
How to Apply the Numbing Cream
1. Purchase a topical numbing cream.
2. Wash the area receiving laser treatment with soap and water. Dry area
completely.
3. Apply a thick amount of numbing cream to the area and rub in thoroughly.
4. Now that the cream has been rubbed into the tattoo, place an additional, thin
layer of cream over the area.
5. Cover the cream with plastic wrap (saran wrap). The heat under the plastic
wrap helps activate the cream. And keeps the cream form drying off.
6. Leave the plastic wrap on until it is removed by the professional before the
procedure.
Tips & Warnings
Leave the cream on the skin longer for better results. Dont remove the saran
wrap until you feel the numbing effect.
How does it work?
Topical anesthetics reversibly obstruct nerve conduction close to their site of
administration, thereby producing temporary loss of sensation in a limited area. Nerve
impulse conduction is blocked by diminishing nerve cell membrane permeability to
sodium ions, possibly by competing with calcium-binding sites that control sodium
permeability. This change in permeability results in reduced depolarization and an
increased excitability threshold that, ultimately, prevents the nerve action potential
from forming.
Skin Absorption
Skin absorption is highly variable. Most painkiller agents exist as solids and are only
superficially absorbed through intact skin. Eutectic mixtures result in liquids that
liquefy at lower temperatures than their single components. This permits elevated
concentrations of anesthetics, which results in superior dermal anesthesia for intact
skin. Other methods of increasing skin penetration incorporate liposomal preparations,
iontophoresis, and transdermal patches.
A fresh double-blind, paired study of 82 adult volunteers compared a
lidocaine/tetracaine transdermal patch (Synera) with lidocaine/prilocaine cream prior
to vascular access at the antecubital site. The lidocaine/tetracaine patch provided
helpful anesthesia in as little as 10 minutes and results showed superior anesthesia at
all application times less than 60 minutes.
Indications
Topical anesthetics are used for a variety of skin and mucous membrane conditions,
including (but not limited to) pruritus and pain due to minor burns, skin eruptions (eg,
varicella, sunburn, poison ivy, insect bites), and local analgesia on intact skin. With
the exemption of lidocaine-prilocaine as a eutectic mixture, topical anesthetics are
poorly absorbed through intact skin. Because of differences in systemic absorption
and toxicity, the ideal choice of topical anesthetic and particular concentration
depends on the intended use. It has also been applied to children to reduce discomfort
prior to injections or to starting an intravenous line.
