Antibiotics for Salmonella infection

Salmonella commonly causes diarrhoea, abdominal cramps, fever, nausea, or vomiting. For an otherwise well person with illness limited to the gut, hydration and monitoring may be more useful than an antibiotic. Unnecessary treatment can cause side effects and encourage antibiotic resistance.

A clinician may consider antibiotics when infection is severe, has entered the bloodstream, or could spread beyond the bowel. Age, immune function, pregnancy, major long-term conditions, and implanted or abnormal blood vessels can influence that decision. Stool or blood testing may help identify the organism and guide medicine choice.

Replace fluid losses with frequent drinks; an oral rehydration solution can also replace salts lost through diarrhoea. Continue light food as tolerated. Do not begin leftover antibiotics or anti-diarrhoeal medicine without advice, particularly when fever or blood in the stool is present.

Wash hands carefully after using the toilet and before handling food. Avoid preparing food for others while unwell, and follow local public-health or workplace instructions if you handle food, provide care, or work with young children. If an antibiotic is prescribed, take it as directed and report troublesome reactions.

Get urgent medical help for confusion, fainting, severe weakness, very little urine, inability to keep fluids down, severe abdominal pain, or blood in the stool. Prompt assessment is also sensible for worsening fever, symptoms in a baby, or illness in someone with a weakened immune system. New breathlessness, a rapidly worsening condition, or signs of severe dehydration should not wait for a routine appointment.

Ask whether testing is needed, what feature makes antibiotic treatment appropriate, and how to maintain hydration safely. Mention recent travel, possible food exposures, pregnancy, immune-suppressing treatment, allergies, and any medicines already taken. Confirm which changes mean you should return for reassessment.
