The best medicine for dysentery depends on whether the cause is bacterial (like Shigella) or parasitic (amoebic). For bacterial dysentery, antibiotics like Ciprofloxacin or Azithromycin are commonly prescribed. For amoebic dysentery, antiparasitic drugs like Metronidazole are used. Because taking the wrong medication can make your symptoms worse, it is crucial to get a stool test first to identify the exact cause. While you seek medical attention, prioritize staying hydrated with Oral Rehydration Salts (ORS) and water. Please consult a doctor for a proper diagnosis and the correct prescription.
