Many people have reported that using ranitidine (a generic form of Zantac) and other anti ulcer drugs like Tagamet have been effective in shrinking warts to the point where they are almost not noticeable at all. In fact even doctors are now prescribing liquid zantac for topical application as wart treatments. However the science behind this effect and the research to back up the use of Zantac, is lacking to say the least.
Several trials have been carried out with mixed results. Some earlier trials seemed to show good evidence that anti ulcer drugs did have a profound effect on shrinking warts, however later trials showed no effect whatsoever. It is also worth noting that no information exists on the safety of using anti ulcer drugs on the skin as this is not the usage they were designed for.
Make your moles, warts, and skin tags disappear(sometimes in as little as 3 days) and
spend more time doing the things that you want to do without fear of pain, infection, or embarrasment.
At present then, the main evidence for the effectiveness of Zantac and other anti ulcer treatments seems to be mostly anecdotal and it certainly seems to have produced results for many if the posts seen on many online forums are anything to go by.
