The researchers surveyed almost 500 patients by phone. They found that people expected their cough to clear up in about 7-9 days if they had a 100.5 degree fever and a cough with mucous. The researchers then reviewed 17 published studies that showed the average cough actually took 18 days to subside. That is almost three weeks!
Most coughs are caused by viruses, even though over 50% of patients with acute cough are prescribed antibiotics. We are uncovering more and more about the way antibiotics affect normal gut flora and also create resistant organisms so overuse is a real public health hazard. As patients understand that coughs can go on and on and do not signal the need for more antibiotics, the better off we will be.
What can you do if you have a lingering cough after a viral infection? Taking a cough suppressant, especially at night so you can get good sleep is critical. Cough lozenges can also help through-out the day. If there is a wheezing, asthma component, a bronchodilator inhaler will help with the cough. Natural cough suppressants can also help. Theobromine, a substance found in chocolate, was found to suppress cough so hot cocoa may help.
Here is another concoction that has been found to suppress cough:
1/4 tsp cayenne pepper
1/2 tsp ginger
1/4 tsp cloves
2 T. honey (or to taste)
2 T. water
1 T. apple cider vinegar
Take 3 tsp. when needed
