We've been hit with yet another gastro bug and the doctor has given us Ondansetron. I actually had giardia last year after returning from Bali and was given the same thing. Wasn't sure if anyone knew if this was sold in Bali over the counter as we've found it to be a miracle with helping to get better. I usually get antibiotics whilst over there as they're not only cheaper but over the counter for us who suffer from infections and viruses throughout the year. Any help is appreciated.
