Cold and runny noses that suddenly start are commonly caused by viral infection, weather changes, allergy or exposure to dust and pollution. Symptoms such as sneezing, watery nose, mild throat irritation, and pressure in the head often improve within a few days with supportive care and rest. Doctors commonly use antihistamine medicines such as cetirizine or levocetirizine to reduce sneezing and a runny nose. Some people also use a combination of cold tablets for nasal blockage, headache, or body pain, depending on symptoms. Warm fluids, steam inhalation, proper sleep, and avoiding cold irritants may also help reduce discomfort naturally. Antibiotics are usually not needed for a simple cold, because most cases are viral. Drowsiness can occur with some cold tablets, so caution is needed while driving or working.
