Always consult a medical doctor or patient care specialist before using lidocaine injections.
Indications and Usage
Lidocaine injections are used to numb an area of your body to help reduce pain or discomfort caused by invasive medical procedures such as surgery, needle punctures, or insertion of a catheter or breathing tube.
Lidocaine injections are also given in an epidural (spinal block) to reduce the discomfort of contractions during labor. It is sometimes used to treat irregular heart rhythms that may lead to heart attack.
Do not take lidocaine injections if:
- You are allergic to lidocaine or other containing ingredients;
- You are allergic to other local anesthetics;
- You are receiving treatment concurrently with class I antiarrhythmic agents (quinine, flecainide, disopyramide, or procainamide);
- You have Stokes-Adams syndrome, Wolff-Parkinson-White syndrome, or cardiac block without a pacemaker;
- You have prior use of amiodarone hydrochloride.
Lidocaine injections for pregnant and nursing mothers are not expected to be harmful to the unborn baby or infant. Consult your doctor or health care professional before using this medication.
The FDA warns that lidocaine should not be used to relieve tooth pain in teething babies, because lidocaine is easily absorbed into the bloodstream and may cause death.

Refer to your doctor or pharmacist for guidelines on dosage. Do not exceed what they advise. The usual dose for adults is 200mg IV slowly over 2 minutes and can be repeated every 4 to 6 hours.
Lidocaine injections can have many possible interactions with other drugs, such as phenothiazines, depressants, or blood pressure medications. Let your doctor know if you have heart, thyroid, circulation, or blood disorders.
Consult your doctor about medications you are taking or existing medical conditions you have before you begin treatment with lidocaine.
