Benzocaine hydrochloride salt is the hydrochloride salt form of the
local anesthetic benzocaine, with the same pharmacological effects
of benzocaine and weaker effect of anesthesia than procaine. Local
absorption is slow with lasting effect. It cannot be used for
anesthesia as a result of not being dissolved in water. It can be
used for pain relief and anti-itch. Benzocaine hydrochloride is
usually made into powder or oil paste and used to heal wounds,
ulcers, burns, skin abrasions and hemorrhoids.
Benzocaine is used to relieve pain and itching caused by conditions
such as sunburn or other minor burns, insect bites or stings,
poison ivy, poison oak, poison sumac, minor cuts, or scratches.
Benzocaine belongs to a group of medicines known as topical local
anesthetics. It deadens the nerve endings in the skin. This
medicine does not cause unconsciousness like general anesthetics do
when used for surgery.
Benzocaine is a topical analgesic (meaning it is to be used on the
body surface or in the mouth but should not be swallowed) that has
a number of different uses in over-the-counter (OTC)
medicines.Depending on the dose and form, the active ingredient
benzocaine can be used to relieve throat and mouth pain;To
alleviate external vaginal itching and burning;To stop pain and
itching due to hemorrhoids;Or to relieve minor skin irritations,
pain, and itching.Because benzocaine is available in different
doses and forms, it is very important to read the Drug Facts label
carefully to determine whether the medicine is intended to be used
for the symptoms you are experiencing.
Benzocaine can be the only active ingredient in oral treatments
that relieve sore throat or address mouth pain caused by cold
sores, canker sores, teething, and other issues.It also can be
combined with other active ingredients in oral treatments that not
only relieve mouth and throat pain, but also protect irritated
areas, provide a soothing coating, or relieve dryness.
While oral discomfort treatments containing benzocaine are intended
to be used in and around the mouth, there are other topical
benzocaine medicines that should only be used externally, or on the
outer surface of the body (not near or in the mouth).For example,
benzocaine can be found in vaginal medicines that contain more than
one external analgesic ingredient or in single active ingredient
hemorrhoid treatments.Benzocaine also is available in topical pain
relievers that not only relieve skin irritations, pain, and
itching, but also contain other active ingredients that kill germs
and help prevent infection.
Benzocaine is approved by the U.S.Food and Drug Administration
(FDA) and is safe and effective when used according to label
directions.Some oral discomfort treatments can be used to
temporarily relieve pain due to toothaches;However, these medicines
are not intended for long-term treatment.If your toothache pain is
severe or lasts for more than seven days, you should talk to your
dentist.Benzocaine may not be contained in all products sold under
