What is the Difference Between Lyrica (Pregabalin) and Gabapentin (Neurontin)?

🆚 Go to Comparative Table 🆚

Lyrica (pregabalin) and Gabapentin (Neurontin) are both anti-epileptic medications used to treat nerve pain and belong to the same class of medicine called gabapentinoids. However, there are several differences between them:

  1. Brand names: Lyrica is a brand name for pregabalin, while Gabapentin is a generic name with brand names such as Neurontin, Gralise, and Horizant.
  2. Absorption and effectiveness: Lyrica is absorbed much better and faster than Gabapentin, starting to work faster (in about an hour) than Gabapentin, which takes longer to start working.
  3. Uses: Both medications have similar uses, but Lyrica has more FDA-approved uses than Gabapentin.
  4. Potential for abuse: The Drug Enforcement Administration (DEA) classifies Lyrica as a controlled substance, while Gabapentin is not currently scheduled as a controlled substance. However, there are documented cases of Gabapentin abuse.
  5. Side effects: Both Lyrica and Gabapentin may cause serious side effects, such as seizures, and withdrawal symptoms if users suddenly stop taking them or reduce the dose.

It is essential not to switch between Lyrica and Gabapentin without consulting a doctor, as they are not interchangeable. Your doctor can help determine which medication is more suitable for your specific needs and condition.
