With treatment, the symptoms of walking pneumonia are alleviated within two weeks, according to Nemours. It also may take up to six weeks for walking pneumonia to resolve.

According to WebMD, mild infections typically do not require treatment and resolve on their own. If treated, a doctor may prescribe antibiotics. Although the symptoms of walking pneumonia are similar to cold and flu symptoms, over-the-counter cold and flu medicines do not relieve walking pneumonia symptoms. If symptoms worsen, the individual should seek medical attention. In pregnant women, children and the elderly, walking pneumonia can progress to more severe forms of pneumonia, according to MedicineNet.
