Antibiotics for pneumonia

A clinician chooses treatment after considering symptoms, examination findings, illness severity and personal health risks. Some people can recover at home, while others need hospital monitoring, oxygen or medicine given through a vein.

Pneumonia is an infection of lung tissue. Bacteria and viruses can produce overlapping symptoms, including cough, fever, breathlessness and chest discomfort, so symptoms alone may not reveal the cause. Examination, oxygen measurement and sometimes chest imaging or laboratory tests help guide care.

The prescription can differ according to where the infection developed, recent antibiotic use, allergies, pregnancy, kidney or liver function and other illnesses. A change of antibiotic may be considered if the clinical response is poor or test results identify a different organism.

Start a prescribed antibiotic as directed, space doses according to the label and finish the course unless a clinician advises otherwise. Check what to do about a missed dose rather than doubling it. Avoid taking leftover tablets because the drug, dose and course may be wrong.

Drink enough fluid, rest and avoid smoking. Fever may settle before cough and tiredness do, but the overall trend should be toward recovery. Arrange review if symptoms fail to improve as expected, return after improving, or side effects interfere with taking the medicine.

Get emergency help for severe difficulty breathing, blue or grey lips, new confusion, collapse, extreme drowsiness, or severe chest pain. A child who is struggling for breath, grunting, unusually floppy or hard to wake also needs immediate assessment.

Seek prompt medical advice for worsening breathlessness, inability to drink, repeated vomiting, reduced urination, coughing up blood or a persistent high fever. Older adults and people with significant heart, lung or immune conditions should have a low threshold for reassessment when their condition declines.

Ask whether the pneumonia is thought to be bacterial, what improvement to watch for, when follow-up is needed and which adverse effects require a call. Also confirm whether regular medicines should continue and whether any chest imaging needs to be repeated after recovery.
