Treatment. In many instances, walking pneumonia resolves on its own within a week or two. However, there are specific steps stricken persons can take to alleviate or potentially expedite their disease process. This includes actions such as receiving adequate rest, remaining hydrated and using over-the-counter medications to reduce fever, pain and coughing. In more severe cases, a doctor might prescribe antibiotics. Though rare, hospitalization might be needed in the most serious manifestations of walking pneumonia.
