The reason for sweating after taking cold medicine is that most cold medicines contain acetaminophen, which is an antipyretic and analgesic drug that can be used to reduce heat treatment when a fever is present and can cause sweating, which can take away the body’s heat and thus play a role in cooling down the body. And cold medicines also contain other ingredients, such as pseudoephedrine or chlorpheniramine maleate, which may also be used to cause sweating, shaking hands or palpitations. Patients with colds who have a low fever and a body temperature below 38°C can generally take cold medicine and drink more warm water without taking antipyretic drugs such as ibuprofen, acetaminophen and nimesulide, so as not to repeat the medication to aggravate sweating and possibly cause deficiency. If the body temperature is above 38.5℃, after taking cold medicine and rechecking the body temperature, the body temperature still does not drop or increases instead after an hour, you can add antipyretic and analgesic drugs to help reduce the fever at this time.
