Medical disclaimer

What is lidocaine 1% with adrenaline (epinephrine)?
Lidocaine 1% with adrenaline (epinephrine) is a combination injection used as a local anesthetic. It is designed to block pain signals in a specific area of the body during medical or dental procedures.
The adrenaline component helps narrow blood vessels at the injection site. This can help the anesthetic last longer and may reduce bleeding in the treated area.
How does it work?
Lidocaine works by blocking sodium channels in nerve cells. This prevents pain signals from traveling to the brain.
Adrenaline adds a vasoconstrictive effect, which reduces blood flow in the area. In practice, this can help keep lidocaine concentrated where it is needed for longer.
Common uses
This medicine is used in a range of clinical settings, including:
- Dental procedures to numb a tooth or surrounding tissue
- Minor surgical procedures such as skin biopsies or excisions
- Regional anesthesia for selected nerve blocks
- Procedures where limiting bleeding may be helpful
The exact use depends on the procedure, the area being treated, and the clinician’s judgment.
Possible side effects
Like all medicines, lidocaine with adrenaline can cause side effects. The original content highlights the following possible effects:
- Allergic reactions such as rash, itching, or swelling
- Dizziness, drowsiness, or confusion
- Changes in heart rhythm, especially in people with existing heart conditions
- Methemoglobinemia, a rare condition that can reduce oxygen delivery in the body
Any severe or unexpected reaction should be assessed urgently by a healthcare professional.

Pregnancy and breastfeeding
