Which antibiotic is used to treat typhoid?

There is no single antibiotic that is suitable in every case. The clinician may adjust treatment when culture and susceptibility results identify which medicines can act against the infecting Salmonella strain.

Resistance differs between regions and can change over time. Recent travel, the place where infection was probably acquired, prior antibiotics, allergies, pregnancy, age, and whether the person can take tablets all influence the prescription.

Blood cultures are particularly useful when collected before antibiotics, provided this does not delay urgent treatment. Severe illness may require hospital care and medicine given into a vein; an uncomplicated case may sometimes be treated by mouth under supervision.

Take the selected antibiotic at the prescribed times and finish it unless the treating team changes the plan. Do not substitute a medicine bought for another infection, and tell the clinician about vomiting or diarrhea that prevents reliable dosing.

Drink safe fluids, follow food and hand-hygiene advice, and attend requested follow-up. Symptoms can take time to settle after effective treatment starts, but deterioration or failure to improve needs reassessment rather than an unsupervised switch of antibiotics.

Typhoid is a potentially serious infection, so suspected illness should be assessed promptly, especially after travel to a place where it occurs. Seek urgent help for severe or increasing abdominal pain, a swollen abdomen, repeated vomiting, blood in stool, fainting, confusion, breathing difficulty, or inability to drink.

Return for review if fever or weakness worsens during therapy, doses cannot be retained, or symptoms recur after the course. Sudden facial swelling, wheeze, or throat tightness after medicine requires emergency help.

Ask whether cultures were taken, what resistance information guided the choice, when results may change treatment, which side effects need attention, and whether follow-up testing or public-health precautions apply.
