How long it takes to recover from a cough without medication depends mainly on the cause of the cough and the severity of the condition. Coughs can be caused by many factors, the most common being respiratory diseases such as cough variant asthma, where the symptoms are generally relatively mild and the allergen is clearly identified, and after leaving the allergen and avoiding re-exposure, the cough can completely subside in a few minutes or so until it disappears. If the infection is relatively mild, there is no need to take any medication. The patient’s own immunity can kill the pathogens and repair the airway by itself, and it takes about 5 days to recover. If the symptoms of the infection are more serious, it may be aggravated without medication and bronchopneumonia or even lung abscess may occur, and this time may require medically necessary anti-inflammatory involvement in the treatment to fully achieve a cure.
