A Sydney gastroenterology clinic, with 5 years experience treating this parasite, prescribe:
Nitazoxinide 500mg 2x daily
Secnidazole 400mg 3 x daily
Furazolidone 100mg 3 x daily
all combined for 10 days
Because Blasto. can be difficult to treat they trialled different combinations of drugs over three years before settling on the above. Their treatment is around 87% effective.
Because Secnidazole and Furaz. can be difficult to source the clinic suggest the following as an alternative:
Septrin DS (dosage is standardised)
Tetracycline hydrochloride 500mg 3xdaily
Nitazoxanide 500mg twice daily
all combined for 10 days.
