Can i take 50 mg tramadol after taking my daily dose of 300 mg gabapentin? thanks?

A drug interaction chart will warn that this combination could augment the sedative properties of both, and you should not drive or otherwise engage in an activity requiring fine motor skills. With those precautions in mind, you can safely take both for the immediate short-term relief of acute pain. Tramadol is a synthetic opiate, and you will develop dependence with continued use.
