Ameba And Giardia-Medicines For Treatment And Dosage.
Ameba causes diarrhea or dysentery. There are usually frequent stools with much mucus and sometimes blood. Often there are gut cramps but little or no fever.
Amebic dysentery is best treated with metronidazole together with diloxanide furoate or tetracycline. Chloroquine is sometimes used when metronidazole is not available or in cases of amebic abscess. Iodoquinol is another medicine used to treat amebic dysentery but it may have dangerous side effects.
In order to kill all the amebas in the gut, very long (2 to 3 weeks) and expensive treatment is necessary. It often makes more sense to stop giving medicines when the person has no more symptoms and then let the body defend itself against the fewer amebas that are left.
This is especially true in areas where the chance of getting a new infection is high.
In diarrhea caused by giardia, the stools are often yellow and frothy but without blood or mucus. Metronidazole is often used.
This medicine is also known as flagyl, it often comes in tablets of 200 or 250 mg. vaginal inserts 500 mg.
