Suggest Treatment For Presence Of Entamoeba Coli In Stools

hello. Since christmas, i started to feel some itching especially on my legs. The thing got worse day by day. Later on i saw my doctor who said it must be an allergic reaction for antibiotics. Unfortunately it was not. I did later other tests and exams (ecography for the abdomen, radiology for the thorax, allergy tests) which did not show any problem. Last week my doctor asked me to make a stool test. The result was that i have a parasite called: entamoeba Coli. My question how can i get rid of it knowing that it is not a pathogenic parasite? I still have the itching problem especially on my butt and legs. thanks very much sam from italy
