Summarize:

If your doctor diagnoses you with amoebicidal dysentery, only a prescription can treat your condition. Ask your doctor to prescribe an amoebicidal medication, and take the full course, following your doctor's instructions as precisely as possible. Even if you stop experiencing symptoms before you finish your prescription, continue to take your medication. Just because your symptoms stop doesn't mean the disease is fully treated yet. The risk of dehydration can be even more critical for amoebic dysentery. Your doctor may prescribe IV fluids depending upon your condition. If you are not hospitalized, you will need a commercial rehydration drink to replenish your water, sugar, and electrolytes. These can be purchased from most pharmacies. Some drinks come pre-made, while others come as a powder you can mix into water. Follow the package instructions carefully if you buy the powdered variety. Use bottled water when possible. Amoebic dysentery can be severe and potentially life-threatening. If you feel severely dehydrated, you have blood in your stool, you are running a high fever, or you have cramps and pains that prevent you from moving or functioning, seek treatment at a hospital immediately.
Ask your doctor for an amoebicidal medication. Rehydrate often. Go to the emergency room for severe symptoms.
