Hi Gretchen, I’ve heard the same. But although I’ve lived in Latin America for more than 12 years, I’ve only done this parasite preventative thing one time. That was in Mexico. I have no idea why I did it… wasn’t sick, etc. I think it was because it was something others said should be done. I’m of the mind that it is unnecessary, especially if you are careful about what you eat. I had an executive check-up in Quito a few months ago and they tested for parasites and my husband and I were both clean.
If you are ever concerned, you can go to a lab with a stool sample and they can check it for you for a few bucks. Id go that route rather than doing the preventative stuff twice a year…
