Pneumocystis pneumonia (PCP) is an infection of the lungs caused by a fungus called pneumocystis. People with healthy immune systems don't usually get infected with PCP. It becomes a problem only when you have a weak immune system that allows the fungus to cause infection. Your immune system can be weakened by such things as cancer, HIV or AIDS, or from the medicines you take after having a bone marrow or organ transplant.
Having PCP can make it hard for you to breathe and get enough oxygen into your blood. The infection can be serious, but many people can be treated at home with antibiotics.
You may also need oxygen therapy, which helps get more oxygen into your lungs and bloodstream.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
