Overview

Pneumonia is an infection of the lungs. Most cases are caused by infections from bacteria or viruses.

Pneumonia may be mild or very severe. If it is caused by bacteria, you will be treated with antibiotics. It may take a few weeks to a few months to recover fully from pneumonia, depending on how sick you were and whether your overall health is good.

How can you care for yourself at home?

• Take your antibiotics exactly as directed. Do not stop taking the medicine just because you are feeling better. You need to take the full course of antibiotics.
• Take your medicines exactly as prescribed. Call your doctor or nurse advice line if you think you are having a problem with your medicine.
• Get plenty of rest and sleep. You may feel weak and tired for a while, but your energy level will improve with time.
• To prevent dehydration, drink plenty of fluids. Choose water and other clear liquids. If you have kidney, heart, or liver disease and have to limit fluids, talk with your doctor before you increase the amount of fluids you drink.
• Take care of your cough so you can rest. A cough that brings up mucus from your lungs is common with pneumonia. It is one way your body gets rid of the infection. But if coughing keeps you from resting or causes severe fatigue and chest-wall pain, talk to your doctor. Your doctor may suggest that you take a medicine to reduce the cough.
• Use a vaporizer or humidifier to add moisture to your bedroom. Follow the directions for cleaning the machine.
• Do not smoke or allow others to smoke around you. Smoke will make your cough last longer. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
• Take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Read and follow all instructions on the label.
• Do not take two or more pain medicines at the same time unless the doctor told you to. Many pain medicines have acetaminophen, which is Tylenol. Too much acetaminophen (Tylenol) can be harmful.
• If you were given a spirometer to measure how well your lungs are working, use it as instructed. This can help your doctor tell how your recovery is going.
