Are there effective over-the-counter medication to reduce a hemorrhoid outbreak?

Yes. First, make certain they are hemorrhoids, and have a doctor look. Second, get some tucks (witch hazel) pads - and follow instructions. Third, get some fiber supplements- like citrucelle - which is over the counter- and start taking it daily.
Depends. If you have a hemorrhoid problem and are helped by over the counter meds, you probably do not have a serious hemorrhoid problem. Prescription hemorrhoid meds help, but there is no substitute for proper dieet and fluid intake to treat or prevent hemorrhoid symptoms.
