Treatments and drugs
By Mayo Clinic staffIf you have blastocystosis without signs or symptoms, then you don't need treatment. 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). However, keep in mind that response to medication for blastocystis varies greatly from person to person. And, because the symptoms you're having might be unrelated to blastocystis, it's also possible that any improvement may be due to the medication's effect on another organism.
