Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Lidocaine Transdermal?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Lidocaine Transdermal?”


  • Patients allergic to para-aminobenzoic acid (PABA) derivatives (e.g., procaine, tetracaine, benzocaine) have not shown cross-sensitivity to lidocaine; however, be aware of the potential for cross-sensitivity in patients allergic to PABA derivatives, especially if the etiologic agent is uncertain
  • If irritation or a burning sensation occurs during application, advise patients to remove the patch and do not reapply until the irritation subsides
  • When used concomitantly with other products containing local anesthetic agents, the amount of lidocaine absorbed from all formulations must be considered
  • Dispose of used lidocaine patches properly to avoid toxicity in small children or pets; used lidocaine patches contain a large amount of lidocaine
  • Application to broken or inflamed skin, although not tested, may result in higher blood concentrations of lidocaine from increased absorption; apply only to intact skin
  • External heat sources (e.g., heating pads, electric blanket), longer duration of application, application of more than recommended number of patches, smaller patients, impaired elimination may contribute to increasing systemic absorption from Transdermal patch; advise patients of proper application and duration
  • Severe hepatic impairment may decrease systemic elimination of lidocaine
  • If eye contact occurs, immediately wash out the eye with water or saline and protect the eye until sensation returns

Pregnancy and Lactation

  • Reproduction studies with lidocaine have been performed in rats at doses up to 30 mg/kg SC and have revealed no evidence of harm to the fetus due to lidocaine
  • There are, however, no adequate and well-controlled studies on pregnant women
  • Because animal reproduction studies are not always predictive of human response, should be used during pregnancy only if needed
