Chericof Syrup is primarily used to treat dry coughChericof Syrup is a combination of three drugs: Chlorpheniramine (antihistamine), Phenylephrine (decongestant) and Dextromethorphan (cough suppressant). Chlorpheniramine works by blocking the action of histamine, a substance responsible for causing allergic reactions. Phenylephrine helps shrink the blood vessels in the nasal passage, reducing a stuffy nose. Dextromethorphan works by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Collectively, it helps to provide relief from dry cough. Chericof Syrup should be taken as prescribed by the doctor. Chericof Syrup is a combination drug belonging to a medication class called 'cough and cold preparations' primarily used to treat dry cough. Chlorpheniramine works by blocking the action of histamine, a substance responsible for causing allergic reactions. It helps relieve allergy symptoms such as sneezing, running nose, watery eyes, itching, swelling, congestion or stiffness. Phenylephrine is a 'decongestant' that helps shrink the blood vessels located in the nasal passage, thereby reducing stuffy nose. Dextromethorphan works by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Thus, Chericof Syrup helps to relieve overall cough, cold and allergic symptoms.
