PREPARATIONS: Lidocaine patch: 5%
STORAGE: Store lidocaine patches between temperatures of 15 C to 30 C (59 F to 86 F).
PRESCRIBED FOR: Lidocaine patches are prescribed for relief of pain associated with postherpetic neuralgia.
DOSING: The recommended dose for lidocaine patches is to apply up to three patches, for up to 12 hours within a 24-hour period. Apply patches to intact skin to cover the most painful area; apply to intact skin, not over blisters or other skin that is not intact.
DRUG INTERACTIONS: Lidocaine patches should be used with caution with anti-arrhythmia medications like amiodarone (Cordarone), propafenone (Rhythmol), sotalol (Betapace), tocainide (Tonocard) and mexiletine (Mexitil) because such combinations can affect heart rate and rhythm and cause other additive side effects.
