Mild signs and symptoms may improve on their own within a few days.Potential medications for treating blastocystosis include the antibiotic metronidazole (Flagyl), the combination medication sulfamethoxazole and trimethoprim (Bactrim, Septra, others) and the antiprotozoal medication iodoquinol (Yodoxin, others).
