Alcohol abstinence is recommended during pneumonia. Alcohol consumption may aggravate the symptoms of pneumonia and may cause adverse drug reactions, so a light diet is recommended during pneumonia. Clinical symptoms of pneumonia include fever, cough and sputum, etc. Alcohol absorption into the bloodstream stimulates vasodilatation and accelerated blood flow, which may aggravate the above symptoms and slow down the recovery of pneumonia. In addition, pneumonia requires anti-infective treatment with medication. Drinking alcohol while taking medication will aggravate the burden on the liver and may cause adverse reactions such as skin rashes and headaches. At the same time, it should be noted that, if you take drugs such as cephalosporin and other cephalosporin antibiotics, absolutely prohibit the consumption of alcohol. Cephalosporins and alcohol can have a diazoxide reaction, and a severe diazoxide reaction can be life-threatening. During the cold, it is recommended to quit smoking and drinking, and eat a light diet. The above medications need to be used under the guidance of a clinician.
