My wife got a Rx for Gabapentin yesterday to deal with chronic pain affecting her lower right leg below the knee. They couldn’t find anything obviously wrong and I guess that in those situations they fall back on Gabapentin. The instructions simply said take as needed and I am somewhat sceptical of this as it’s my understanding that Gabapentin is not like an analgesic which you do take on an as needed basis. I thought that for Gabapentin, once you start the meds, you continue at least until the meds is finished. She was given a one month supply.
