About pain and medicines to cure it

Before learning more about benzocaine, it’s important to go through a couple of details about what pain is and how to deal with it properly.

Pain is the body’s way of indicating that something is not working as it should. That is why it appears in case of illness, blows, cuts and other health problems.

For pain relief there are two groups of drugs: analgesics and anesthetics.

  • painkillers They are responsible for preventing nerve impulse transmission, numbing the area and preventing the perception of pain.
  • anesthetics they completely block the pain, both in a state of consciousness and asleep.

It is important to note that there is no anesthetic that can be used interchangeably, therefore, self-medication is not recommended. It must always be the doctor who prescribes the drugs to his patients and the type of treatment they must follow.

Use of benzocaine

What is benzocaine
Benzocaine has several presentations: sprays, suppositories, solutions and even in the form of a gel for the gums or drops for optical application.

Benzocaine works by blocking the transmission of nerve impulses. The mechanism by which they achieve this effect is by blocking sodium channels.

Adverse effects of benzocaine

Most local anesthetics are highly effective and are used in routine practice. However, they must be used very carefully, according to the doctor’s instructions, otherwise adverse reactions may occur in some cases.

It must be taken into account that most of local anesthetics have both stimulating and depressant effects on the central nervous system. In low concentrations, sedatives predominate, but when increased, stimulants increase, which can cause restlessness or trembling.

In general, hypersensitivity reactions are less frequent, which can lead to the appearance of allergic dermatitis.

Benzocaine should be used very carefully in children as it can cause methemoglobinemia, an adverse reaction which in some cases can be fatal. It is in fact totally contraindicated in children under the age of two, given the risk it poses to their health.
