Cochrane review on gabapentin for neuropathic pain
This Cochrane review is abstracted in the February 1 issue of American Family Physician. Gabapentin is effective with a number needed to treat (NNT) of 4. Adverse effects including dizziness, somnolence and headache occur with a number needed to harm (NNH) of 4. This is a significant trade off which must be gauged by patient preference. Tricyclics and carbamazepine have lower NNTs and are less expensive.
