Fungal infections of the lung, also known as aspergillosis because they are commonly caused by the fungus Aspergillus, require antifungal drugs to treat, according to the Merck Home Health Handbook. In some cases, the infection is so extensive that surgery is necessary to fully eradicate the fungus.
Fungal infections of the lung require antifungal drugs to heal, reports the Merck Home Health Handbook. Normally, doctors prescribe drugs such as amphotericin B or voriconazole, but these may be ineffective against some strains of fungi. In these cases, a doctor may prescribe a newer antifungal drug such as caspofungin. These drugs may be used alone or in combination for a synergistic effect against the infection. While most fungal infections of the lungs are not serious conditions, infections that are located near blood vessels require immediate surgical excision because they can invade the blood supply and cause bleeding in the lungs.
Before treatment, a medical professional attempts to identify the strain of fungus in the lungs by taking a sample of it with a bronchoscope and sending it to the lab, adds the Merck Home Health Handbook. Doctors also commonly use X-rays and CT scans to diagnose fungal infections. Symptoms of fungal infections in the lungs include a bloody cough, fever, chest pain and difficulty breathing.
