off-label drug use

The mad rush to rid this country of demonic prescription analgesic drugs (mainly Vicodin and Percocet) has put pain patients and their doctors in an unprecedented dilemma. What can they do for pain when real drugs are unavailable? Many have turned (or been forced to turn) to the epilepsy drug Neurontin, which is used off-label for pain. But does it work? Please read this and find out.
Drugs submitted for FDA approval must have safety and efficacy data for the condition they're designed to treat. Sometimes, however, a drug is found to be effective for another condition, and doctors are within their rights to prescribe it for such "off-label" uses. Such may soon be the case for metformin.
