Antiprotozoal medicine is medication that helps to kill tiny little creatures called protozoa that can make people feel sick. Protozoa are very small living things that can live in the water or in other organisms, including people. They can cause infections and diseases that can make people feel really bad. But antiprotozoal can help fight against these infections and help people feel better. Think of antiprotozoal medicine like a superhero that comes in to save the day and beat up the bad guys (protozoa) so you can feel better.
