was told by friends in Bali NOT to take these tablets as there is a problem with the compounds. Apparently there was an article in one of the Bali Newspapers 6 monhts ago with regards to adverse effects and a couple of deaths that may be linked to these tablets. I have used them in Bali previously and found them to be fantastic for colds, even brought them back to Oz. Had 3 boxes ready to bring back this time until I was told to get rid of them. Try green cold and flu panadol.These are just as good and come in daytime and night time.
