Antibiotics for pertussis treatment

They may lessen symptoms when given near the beginning of the illness. Once repeated coughing fits are established, an antibiotic may not stop the cough promptly because airway irritation can persist after the bacteria have been controlled.

Pertussis, also called whooping cough, is a bacterial respiratory infection. A clinician may treat a suspected case before a test result is available when the symptoms and exposure history fit. Treatment also helps limit transmission to other people.

Household members or other close contacts may need preventive antibiotics after an exposure, particularly when someone at higher risk of severe illness could be affected. The clinician considers age, pregnancy, medical history, medicines and the timing of contact before choosing a plan.

Take the prescribed antibiotic exactly as directed and complete the course unless the prescriber changes it. Do not use leftover medicine or share a prescription. Tell the clinician about allergies, pregnancy, liver problems and all regular medicines because these details can affect antibiotic choice.

Rest, drink enough fluid and avoid smoke or strong fumes that provoke coughing. Follow the clinician's advice about staying away from work, school or vulnerable contacts; contagiousness depends on whether effective treatment has begun and how long symptoms have been present.

Seek emergency care for severe breathing difficulty, blue or grey lips, pauses in breathing, collapse, confusion or a seizure. Babies with suspected pertussis need prompt medical assessment because they may have breathing pauses without a typical whoop.

Contact a clinician promptly if coughing fits prevent drinking, cause repeated vomiting, are worsening, or occur after known exposure to pertussis. Get advice if an antibiotic causes facial swelling, wheezing, a widespread blistering rash or severe persistent diarrhoea.

Ask whether testing is needed, when you may return to school or work, which close contacts should be assessed, and what to do if a dose is missed or vomited. Parents can also ask how to recognise breathing pauses and maintain hydration during coughing spells.
