Q. Early this summer, I got poison oak and couldn’t find the anti-itch cream. I was desperate so I used my rosacea medicine, MetroGel (metronidazole gel 0.75%), hoping for any relief.
Not only did the itch stop within minutes, but by morning the redness and blisters were gone. Several other people have tried it with the same results.
My family doctor and my dermatologist are astonished. It works for me even though they say there is no reason it should.
A. Thanks for a fascinating report. We could find no mention of this use for metronidazole in the medical literature.
