Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Lidoderm (lidocaine 5% patch) and Norpramin (desipramine) are both prescription medications that treat nerve pain, but they belong to different classes and treat different conditions. Lidoderm is used to relieve nerve pain from shingles, known as postherpetic neuralgia, by numbing the skin. Norpramin, on the other hand, is a tricyclic antidepressant (TCA) used to treat depression by increasing serotonin and norepinephrine levels in the brain. It's also used off-label for certain types of nerve pain. Lidoderm is applied topically as a patch and can be worn for up to 12 hours, while Norpramin is taken orally, usually once a day. Common side effects of Lidoderm include skin irritation and redness, while Norpramin can cause sleepiness, confusion, and weight gain. Additionally, Norpramin has more serious risks, such as suicidal thoughts and heart problems, and it interacts with a wider range of medications compared to Lidoderm.

Summary of Lidoderm vs. Desipramine
Summary for Local anesthetic
Prescription only
Lidocaine 5% patch (Lidoderm) is a prescription medication used to relieve nerve pain caused by a shingles infection, also called postherpetic neuralgia (PHN). It's a local anesthetic that works by numbing your nerves to help reduce pain. You apply the patch directly to the painful area of your skin once a day, and it can be worn for up to 12 hours in a 24-hour period. Common side effects include temporary skin irritation, redness, and a mild burning sensation where the patch is applied.
Summary for Tricyclic antidepressant (TCA)
Prescription only
Desipramine (Norpramin) is an tricyclic antidepressant (TCA). It's FDA-approved to treat depression in adults, but it's not a first-choice medication for this condition. Desipramine (Norpramin) is taken by mouth, typically once per day. Side effects of this medication include sleepiness, confusion, and weight gain. It's best to avoid drinking alcohol while taking desipramine (Norpramin) because doing so can worsen side effects.
