An In-Depth Look at the Topical Anesthetic Lignocaine

Lignocaine is a popular topical medication used to numb the skin and relieve pain. This post takes a closer look at everything you need to know about using lignocaine cream or gel.

What is Lignocaine?

Lignocaine contains the active ingredient lidocaine, which provides localized numbness when applied to the skin. It comes in the form of a cream or gel for topical use.

Common Uses

Some of the most common uses for lignocaine include:

  • Relieving pain from minor burns, insect bites, hemorrhoids
  • Numbing the skin during waxing procedures
  • Providing localized anesthesia for minor exams or surface-level procedures

How to Use

  • Apply a small amount directly to the affected area
  • Dosage: Use no more than 1-2 mL, once or twice daily
  • For cracked nipples, apply after each feeding

Side Effects

Side effects are rare but may include:

  • Skin irritation
  • Localized allergic reaction

Key Tips for Safe Usage

  • Avoid contact with eyes as this can cause temporary irritation
  • Talk to your doctor to see if lignocaine is appropriate for your specific condition and medical history

How Lignocaine Works

The lidocaine in lignocaine penetrates into the top layers of skin, temporarily numbing nerve endings and blocking pain signals. The duration of numbness depends on factors like:

  • Dose amount
  • Contact time with skin
  • Use of occlusive dressings
  • Area of application

Is Lignocaine Safe During Pregnancy?

While there is limited evidence showing harm to a fetus or newborn, it’s best to exercise caution and consult your doctor before using lignocaine while pregnant or breastfeeding.

Studies in animals have not shown any direct adverse effects, but human data is lacking. The low amount of absorption into the bloodstream is generally not enough to cause toxic effects.

The Takeaway on Lignocaine:

  • Provides temporary numbness and pain relief when applied topically
  • Available as a cream or gel
  • Safe for most people when label directions are followed
  • Pregnant or breastfeeding women should ask their doctor before using
