What should you know about antibiotics for enteritis?

Enteritis means inflammation of the small intestine. It may follow an infection, contaminated food, another illness, or an inflammatory condition. Antibiotics act on selected bacteria, not viruses, and an unnecessary course can cause side effects or make future infections harder to treat. A clinician may use the history, examination, stool testing, and signs of dehydration to decide what is appropriate.

Drink frequent small amounts of fluid and follow the treatment plan provided. If antibiotics are prescribed, take them exactly as directed and do not share leftover tablets. Tell the clinician about allergies, pregnancy, kidney problems, and other medicines. Diarrhoeal illness can resemble conditions such as [Giardiasis](/conditions/giardiasis/) or [Helicobacter Pylori Infection](/conditions/helicobacter-pylori-infection/), which need different approaches.

Arrange medical assessment for ongoing diarrhoea, fever, significant abdominal pain, blood in stool, or symptoms after unsafe food or travel. Seek urgent care for fainting, confusion, severe weakness, very little urine, repeated vomiting, or inability to keep fluids down. Do not delay care while waiting to see whether leftover antibiotics help.

Ask what cause is suspected, whether testing is needed, what improvement should look like, and which side effects require stopping the medicine or contacting the clinic.
