Neuropathic pain

Gabapentin is recommended as a first-line treatment for chronic neuropathic pain by various medical managers.

In addition to these two neuropathies, a guide to the European Federation of Neurological Societies notes the efficacy of gabapentin for central pain. A combination of gabapentin-containing opioids or nortriptyline may work better than a single drug.

For example, the use of gabapentin before joint surgery or laparoscopic surgery increased the risk of respiratory depression by 30-60%.

Rebound symptoms usually occur 1-2 days after abrupt discontinuation of gabapentin. Anxiety confusion and confusion are the most frequently reported followed by intestinal complaints and sweating, unusual tremors, tachycardia, high blood pressure, and insomnia.
