Pneumonia (Adult)

Pneumonia is an infection deep within the lung, in the small air sacs (alveoli). It may be due to a virus or bacteria and is usually treated with an antibiotic. Severe cases require treatment in the hospital. Milder cases can be treated at home. Symptoms usually start to improve during the first 2 days of treatment.

Home Care:

  • Rest at home for the first 2–3 days or until you feel stronger. When resuming activity, don’t let yourself become overly tired.

  • Avoid exposure to cigarette smoke (yours or others).

  • You may use acetaminophen (Tylenol) or ibuprofen (Motrin, Advil) to control fever or pain, unless another medicine was prescribed. [NOTE: If you have chronic liver or kidney disease or ever had a stomach ulcer or GI bleeding, talk with your doctor before using these medicines.] (Aspirin should never be used in anyone under 18 years of age who is ill with a fever. It may cause severe liver damage.)

  • Your appetite may be poor so a light diet is fine.

  • Keep well hydrated by drinking 6–8 glasses of fluids per day (water, sport drinks such as Gatorade, sodas without caffeine, juices, tea, soup, etc.). This will help loosen secretions in the lung, making it easier for you to cough up the phlegm (sputum). If you also have heart or kidney disease, check with your doctor before you drink extra amounts of fluids.

  • Finish all antibiotic medicine prescribed, even if you are feeling better after a few days.

Follow Up

with your doctor in the next 2–3 days (or as advised) to be sure you are responding properly to the medicine.

[NOTE: If you are age 65 or older, or if you have chronic lung disease (asthma, emphysema or COPD), we recommend the pneumococcal vaccination and a yearly influenza vaccination (flu-shot) every autumn. Ask your doctor about this.]
