Sudafed Decongestant Tablets (Non-Drowsy) keep you alert and awake while treating some of the most irritating and disruptive symptoms of cold and flu: runny nose and blocked airways . The soothing tablets are also an effective treatment for catarrh which is a build-up of thick and runny mucus as a result of airway inflammation. They also help to break up other stubborn collections of mucus in the chest and throat resulting in less violent coughing and the clearing of airways. In fact Sudafed contains a decongestant which reduces nasal congestion and helps to unblock the sinuses for pain relief and better airflow. As well as this symptomatic relief the treatment is effective in the long term. Bacteria and microbes living in the pools of mucus and blocked airways can prolong or even worsen cold and flu infection. By helping to clear away these unhygienic bacterial habitats Sudafed gives your body a fighting chance of throwing off the disease more quickly and permanently.
