Upsides
  • Lidoderm (Lidocaine) can treat pain better for people who can't take oral pain medications due to allergies or bad side effects.
  • Has been shown to relieve nerve pain due to shingles for up to 12 hours at a time.
  • Patches can be cut into smaller pieces to best fit the areas of skin they need to be used on.
  • Lowers the frequency of seizures, especially for people with tonic-clonic and partial seizures.
  • First-line option for trigeminal neuralgia (nerve pain involving the face, head, and neck), and can relieve other types of nerve pain.
  • May be helpful in stabilizing mood for people with bipolar disorder.
Downsides
  • 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.
  • Interacts with many other medicines and supplements.
  • Higher risk of skin reactions compared to other antiepileptic medicines, ranging from mild to life-threatening rash.
  • Can cause blurry vision, dizziness, and upset stomach.
  • Not safe to use if you're pregnant.
  • Requires routine blood tests to see how the medicine is affecting your body.
