Welcome to healthcare Magic!
How were you able to know that it is Amebioasis. If proven by stool examination then you must get a proper treatment under the supervision of a qualified physician.
There are many drugs apart from tinidazole/metronidazole
which are effective against amebiasis
like Quiniodochlor, Diloxanide Furoate etc. to name a few.
The dose and regimen your clinician would know.
I do not agree with your choice of taking ciprofloxacin
for amebiasis, you are harming yourself by self medication
I hope the advise would be informative and useful for you.
