How Long Does Novocaine Last

What is novocaine?

Novocaine, a brand of procaine, is a local drug. Local anesthesia is a medicine or technique used to numb a particular part of the body. Unlike General anesthesia, local anesthetics do not make you lose consciousness.

Local anesthetic can be used during the following minor procedures:

• filling the tooth cavity
• the removal of wisdom teeth
• minor skin procedure, such as removing a mole or wart
• biopsy (when a tissue sample is removed from a part of your body for examination under a microscope)

Developed in 1905, Novocaine became the first synthetic local anesthetic to be widely used in the United States. Before novocaine, cocaine was often used as a local anesthetic. While many new local anesthetics have since been developed, Novocaine is still sometimes used during certain procedures.

How it works

Novocaine works by obstruction the nerves in your body from causation pain signals to your brain. The doctor or dentist can use it to stun the part of the body they are working on, so you don’t feel any pain during the procedure.

How long does Novocaine last?

The effect of novocaine usually does not last very long in the body. In fact, Novocaine is an injectable anesthetic with the fastest action. After the introduction of Novocaine, you will begin to feel numb after 5-10 minutes. Numbness usually lasts 30 to 60 minutes.

Because novocaine itself has a very short duration, it is often used in combination with adrenaline (adrenaline) to make the effect even longer. If novocaine is administered with adrenaline, the effect lasts about 90 minutes.

Factors that affect how long novocaine lasts

How long the effects of the last novocaine also depend on the dose administered by your doctor or dentist. The dose depends on the type of procedure you have, the size of the area that should be numb, and the number of nerves that need to be blocked.

Your doctor may also give you a higher dose if they want to stun the area for a longer period of time to complete the procedure. The effects of novocaine also vary slightly from person to person.

In the body, Novocain is processed (metabolized) by associate accelerator called pseudocholinesterase. About 1 in every 5,000 people have a genetic condition that makes them unable to destroy (hydrolyze) novocaine and similar drugs.

This condition is called deficit pseudocholinesterase. This is more common in some populations, including the Persian Jewish community and Alaska natives. People with this deficiency are more sensitive to novocaine, and its effects can last much longer.

Risks and side effects

Risks of using Novocaine

Novocaine is considered to be very safe. Novocaine can overdose, but your doctor and dentist will use careful calculations to prevent this from happening. The use of Novocaine along with adrenaline can also help to reduce the risk of overdose, as there is less of novocaine necessary to maintain a constant numbness.

Novocaine is injected into the body, which can be uncomfortable or painful for some people. You may feel a burning sensation for a few seconds when you administer the drug. As the effects of Novocaine wear out, you may feel tingling in the area where it was introduced. The area may also feel pain.

The side effects of novocaine are usually very mild and tend to disappear quickly. They may include:

• numbness or tingling sensations (e.g. pins and needles)
• a headache
• dizziness
• drowsiness
• muscle twitching
• minor pain at the injection site

allergic reaction to novocaine, but it’s extremely rare. Symptoms of an allergic reaction to novocaine include:

• itch
• hives
• difficulty breathing
• swelling of face or hands
• loss of consciousness

The duration of action of procaine

Novocaine is a short-acting local anesthetic. Its effect usually lasts from 30 to 60 minutes. If novocaine is used together with adrenaline, the action can last up to 90 minutes.

The duration of novocaine is influenced by several factors, including:


The dose of novocaine administered will depend on the procedure performed. The higher the dose of novocaine, the longer the numbness will continue.

The dose depends on:

• type of procedure performed;
• the number of pain nerves;
• the size of the treated area.

Presence of infection

Anesthesia is less effective when used on an infected tooth. The infection causes the tissue surrounding the tooth to become acidic and local anesthesia to be sensitive to pH levels. Inflammation also reduces the effectiveness of local anesthesia, especially during dental procedures. Because of this, the dentist may need to use more novocaine on an infected tooth than on a healthy tooth.

The use of adrenaline

The use of epinephrine with novocaine is an important factor in determining the length of time the area will remain numb. Adrenaline causes constriction of blood vessels. This reduces blood flow around the injection site and keeps the anesthetic longer than usual. Adrenaline also reduces bleeding.

People with some medical conditions, such as heart disease or high blood pressure, anesthesia is best done without adrenaline.

Why do I need novocaine?

Novocaine is commonly used during dental procedures. It was developed in 1905 and became a widely used local anesthetic in the United States. Local anesthesia does not cause a loss of consciousness before a medical procedure, in contrast to the General anesthesia. People who receive a local anesthetic are awake during the procedure but feel no pain.

Novocaine and similar drugs block the pain signals that nerves send to the brain. Local anesthetics are commonly used during dental procedures such as tooth extraction or treatment.

They are also used during other minor procedures, including:

• wart removal;
• cataract removal;
• a biopsy that involves taking a tissue sample for examination;
• insert the pacemaker.

In recent years, novocaine has been replaced by new local anesthetics, as their effect lasts longer.

The dentist inserts novocaine into the gum tissue around the affected tooth. Most people get a burning sensation. This feeling is not caused by a needle, and anesthesia, entering the tissue. Novocaine acts quickly, and numbness occurs within 5 minutes. At this point, people no longer feel pain, although they may feel pressure or movement around the treated area.

As soon as the anesthesia passes, the person begins to feel the gums and then the lips and tongue. People may have difficulty eating, drinking, can’t speak clearly until the numbness has passed.
Novocaine-side effects

Novocaine is considered a safe remedy. The most common side effects are:

• tingling and slight pain at the injection site;
• dizziness;
• a headache;
• drowsiness;
• twitching of the muscles.

These effects are usually mild and go away within a few hours.

Allergy to novocaine

More serious side effects are associated with allergies to novocaine, but they are rare. Symptoms of Allergy to novocaine include:

• difficulty breathing;
• urticaria;
• itch;
• loss of consciousness;
• edema.

Other rare side effects that require emergency medical care include:

• chest pain;
• arrhythmia;
• nausea;
• vomiting;
• shiver;
• convulsion.

It is very important that the person tells the dentist about the drugs he is taking, as some drugs can interact with novocaine.

It is also important that people inform the dentist about the state of health to choose the best anesthesia and the right dose.

When is the effect of novocaine

Usually, the effects of novocaine pass when blood circulation increases and transfers the drug into the bloodstream.

Local anesthesia can be faster if a person goes for a walk or is engaged in activity after treatment. Physical activity increases blood flow in the body. However, you must obtain permission from your doctor before exercising after the procedure.

In recent years, new local anesthetics, including lidocaine (Xylocaine) and articaine, have been used instead of novocaine. These drugs are also safe to use, and their effect lasts longer than novocaine.
