Campylobacter treatment and antibiotics

Campylobacter often settles with rest and careful fluid replacement. Antibiotics may be considered when symptoms are severe, prolonged, involve invasive infection, or affect someone whose health makes complications more concerning. The choice depends on examination, local prescribing practice, allergies, other medicines, and sometimes stool testing. Do not use leftover antibiotics or share a prescription.

A medicine can have side effects and may not work against every strain. Antibiotic treatment for another condition, such as [Acute Bronchitis](/conditions/acute-bronchitis/) or [Cellulitis](/conditions/cellulitis/), should not be used as a substitute for assessment of diarrhoea.

If prescribed an antibiotic, take it exactly as directed and tell the prescriber about allergies, pregnancy, kidney problems, and regular medicines. Ask what to do if vomiting occurs after a dose or if diarrhoea worsens. Continue replacing fluids and follow food-safety advice. Stop and seek advice for a serious reaction such as facial swelling, breathing difficulty, or a widespread blistering rash.

A clinician may arrange a stool sample before treatment or if symptoms continue. Avoid self-treating with antibiotics obtained without a prescription.

Get urgent help for severe dehydration, fainting, confusion, blood in the stool, severe abdominal pain, inability to drink, or breathing difficulty. Arrange prompt review if fever is worsening, symptoms are persistent, or you have a weakened immune system. Seek immediate help for signs of a severe antibiotic allergy.

Ask whether your symptoms justify antibiotics, whether a stool test is useful, how to take the prescribed medicine, and which side effects should prompt a call.
