Antibiotics in cholera treatment

Cholera can cause sudden, profuse watery diarrhoea and vomiting. The immediate danger comes from losing water and electrolytes faster than they can be replaced. An appropriate oral rehydration solution helps restore both; severely unwell people may need intravenous fluids. An antibiotic can shorten the illness in selected patients, but it cannot correct established dehydration on its own.

Begin properly prepared oral rehydration solution promptly and arrange medical assessment. Follow packet directions exactly because adding too much or too little water creates the wrong salt concentration. Continue small, frequent sips if vomiting occurs. Take an antibiotic only when prescribed, using the named dose and schedule; choice depends on clinical circumstances and local resistance patterns. Do not use leftover medicine or share a prescription.

Go for emergency treatment if watery diarrhoea is heavy or frequent, the person cannot drink, vomiting prevents fluid replacement, urine becomes very scant, or there is marked thirst, weakness, drowsiness, confusion, dizziness or fainting. A child who is unusually sleepy or unable to feed also needs urgent assessment. Do not delay care while waiting to see whether an antibiotic works.

Confirm which rehydration fluid to use, how to replace ongoing losses and whether intravenous treatment is needed. Ask why a particular antibiotic was selected, how to take it, and what to do if a dose is vomited. Tell the clinician about pregnancy, allergies, kidney problems and every medicine already being taken.
