Severe systemic toxicity from local anesthetics like lidocaine occurs in up to 1 in every 2,000 peripheral nerve blocks. So, **what happens if lidocaine is absorbed into the bloodstream**? It can lead to a dangerous condition called Local Anesthetic Systemic Toxicity (LAST).

While lidocaine is a widely used local anesthetic, medical sources confirm that vomiting can be a side effect, particularly in instances of systemic absorption or toxicity. This adverse reaction is often a symptom of the body reacting to higher-than-normal levels of the drug in the bloodstream.

The incidence of severe systemic toxicity from local anesthetics is estimated to be as high as 1 in 2,000 for certain peripheral nerve blocks [1.4.1]. Understanding where should lidocaine not be injected is crucial for patient safety and preventing adverse outcomes.

While commonly known as a topical anesthetic, intravenous (IV) lidocaine has distinct systemic uses, including treating specific heart conditions and managing chronic pain. However, the systemic administration raises critical questions, including, **what happens if you give lidocaine IV**, and what are the associated risks and potential for toxicity.

According to the FDA, misuse of high-concentration, over-the-counter topical lidocaine products can lead to serious adverse health effects, including seizures and cardiac issues. To ensure safety, it is critical to know **where should you not apply lidocaine** and to follow all usage instructions precisely.

Inadvertent intravascular injection is a primary cause of local anesthetic systemic toxicity (LAST). The effects of this can range from mild neurological symptoms to severe cardiovascular collapse. Understanding **what happens if lidocaine gets into your bloodstream** is critical for recognizing the signs and acting quickly in an emergency.

Approximately 75% of local anesthetic systemic toxicity (LAST) cases manifest within the first five minutes of administration, particularly following an intravascular injection. The speed of onset depends heavily on the route of administration, making the question of how quickly does lidocaine toxicity happen a critical consideration in clinical practice.

While primarily used as a topical medication, topical medicine can be absorbed through the skin and cause systemic side effects throughout the body. As a powerful cytotoxic agent, understanding what are the side effects of podophyllum is crucial for patient safety. It is important for anyone using this medication to be aware of the risks, from local skin irritation to severe systemic complications caused by excessive absorption.

The U.S. Food and Drug Administration (FDA) has issued strong warnings against using topical anesthetics with excessively high concentrations, like the hypothetical 70% numbing cream, due to the risk of life-threatening side effects. Such products are unregulated, and their purported potency is a marketing gimmick that can lead to severe health complications, including seizures and irregular heartbeats.

The FDA has reviewed at least 22 cases of serious adverse reactions in children from oral viscous lidocaine, including six deaths [1.10.4]. So, **what happens when lidocaine is ingested?** Ingestion leads to rapid absorption and can cause severe systemic toxicity affecting the brain and heart [1.2.3, 1.2.1].
