"taking it for shingles pain. seems to work well, but makes me tired and a bit dizzy. doctor also prescribed an anti-seizure medicine, gabapentin, so not sure which helped more. the combination seems to work really well for the nerve pain from shingles. i would ask my dr. for these if i ever get shingles again. i went from pretty bad pain to it feeling like someone is tickling me, and it&#039;s slightly unpleasant."
