As cough and cold season bears down, you should stock up on cough syrups and liquids now, before you develop a cold. The Online Drugstore is your source for low-priced cough syrups from brands including Advil, Alka-Seltzer and Mucinex. Persistent coughing can be a miserable experience, particularly if you are at work, school or in public. Cough syrups are designed to provide temporary relief from coughing by thinning and loosening mucus in the airways and clearing congestion. Before taking cough syrup, you should review the directions on the packaging. You should limit cough syrup intake to four, five or six times over a 24-hour period and only take does in quantities as mandated on the label. Taking cough syrup each time you have a cough is counterproductive as taking more cough syrup than recommended can do more harm than good. If you have questions about any cough syrups or if your cough persists after taking the recommended dosages, you should contact your physician.
