Lidocaine HCl Inj

Lidocaine HCl Inj Side Effects

See also Overdose section.

The side effects of lidocaine injection depend on how it is used. Injecting lidocaine into the skin will cause temporary stinging/burning. Injection around the spinal cord (e.g., spinal, epidural anesthesia) may also cause temporary loss of muscle control. Less common side effects may include headaches, backache, and shivering. If any of these effects persist or worsen, tell your doctor promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

The following uncommon side effects usually only occur with higher doses of lidocaine injected around the spinal cord but may occur with numbing of smaller areas of skin if you have severe liver problems. Tell your doctor immediately if any of these unlikely but serious side effects occur:

• lightheadedness
• nervousness
• ringing in the ears
• unusual pleasurable feelings/mood
• confusion
• dizziness
• drowsiness
• nausea
• decreased breathing
• double vision

Tell your doctor immediately if any of these rare but very serious side effects occur with injection around the spinal cord:

• persistent loss of bowel/bladder control
• persistent numbness in the groin or anal areas
• persistent loss of sexual ability

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including:

• rash
• itching
• swelling
• severe dizziness
• trouble breathing

This is not a complete list of possible side effects. If you notice other effects not listed above, tell your doctor immediately.
