My Son Was Diagnosed With Amoebiasis 2 Weeks Ago, He

my son was diagnosed with amoebiasis 2 weeks ago, he was confined for 6 days and was given metronidazole IV, his doctor prescribed him metronidazole oral so he can take his medicine at home,, wasv advised to take it 3x a day however, we were only able to give it to him twice as he didnt like the taste of his medicine. He just poops once a day. do you think his amoeba is healed?
