Lidocaine- A Hazardous Waste?

Lidocaine is a local anesthetic that is probably used in every healthcare facility in the country. It’s useful for minor procedures such as suturing of wounds. We all know that it’s a pharmaceutical product, but is it also a hazardous waste material?

  • Lidocaine is available in various forms such as creams, gels and injections. It works by temporarily blocking the pain signals from flowing along the nerves to the brain.
  • It’s useful because it doesn’t have the sedating effect of general anesthetics so the patient can remain conscious throughout the procedure.
  • Substances are classified as “hazardous” if the formulation has a pH of 2 or less. By definition then, a vial containing lidocaine and epinephrine is not characterized or listed as hazardous waste because it is not corrosive. The pH of lidocaine is between 5 and 7.
  • Lidocaine is considered chemically stable under standard use and storage conditions.
  • It does not cause dermal irritation or corrosion. It does, however, cause temporary numbing of the area it’s in contact with.
  • It also doesn’t cause any ocular irritation from normal handling. It may however cause temporary blurred vision.
  • Safe disposal is however recommended as with all pharmaceutical products.
