Over-the-counter nasal sprays could keep coughs, colds and flu at bay and reduce antibiotic use
Widely available over-the counter nasal sprays could keep upper respiratory tract infections - like colds, chest infections, flu, sore throat, and sinus infections - at bay, and prevent full-blown symptoms from developing, one of the largest trials to date to test their effectiveness finds. The research, which analysed data from nearly 14,000 adults, found overall they reduced the days of illness by around 20 per cent, and also reduced the number of days with severe symptoms, time off work or normal activities, and antibiotic use.
