Downsides and risks
  • Can cause skin irritation after using it the first time, but for most people it's mild and goes away in a few minutes or hours.
  • Used patches contain enough medicine to be dangerous to children and pets, so store and dispose of the patches in a safe place out of their reach.
  • Might not be the best choice if you've had allergic reactions to numbing medications (local anesthetics) in the past.
  • Even though only small amounts of Lidoderm (Lidocaine) are absorbed into the body through the skin, if you're taking medications that treat arrhythmias, Lidoderm (Lidocaine) can affect how they work.
  • Patches shouldn't be left on for more than 12 hours, used on very large areas of skin, or covered with a heating pad.
Coming soon.
