The Dos and Don'ts of Flu Season

The flu season isn't quite done with us! What should you do if you feel it taking hold of you? Here's a list of things that could help and others that are just a waste of time.

Five things worth trying

1. Antivirals. Tamiflu and Relenza have been shown to cut a day or two off the time you spend suffering from the flu. 
2. Analgesics. Ibuprofen and acetaminophen can reduce fever and help ease muscle aches, but patients who have asthma, high blood pressure or other chronic conditions should check with a doctor to ensure it's safe to take them. 
3. Fluids. Clear liquids such as water, broth and sports drinks can help prevent dehydration. 
4. OTC remedies. Decongestants and antihistamines can help ease runny noses, congestion and coughing. 
5. Rest. The best thing to do for yourself and others if you have the flu or a bad cold is to stay home and rest. That way, you won't spread germs - and admit it, you probably wouldn't be that effective at work feeling the way that you do. 

Five things to forget 

1. Herbal supplements. There's very little evidence that any of them work and it's hard to get concrete evidence because they come in different formulations, sometimes even from different types of plants. 
2. Zinc: Again, the different formulations of zinc make it difficult to definitely say whether it boosts the immune system, as claimed. The FDA recommends against using it in the nasal gel form because it can lead to a permanent loss of smell. 
3. Cough syrup: The American Lung Association cautions that there is no evidence that guaifenesin, an expectorant, can help ease a cough. The American College of Chest Physicians recommends against using any cough syrup. 
4. Cold remedies for kids: The FDA says OTC cold, flu and cough remedies shouldn't be given to children under 2 and the Infectious Diseases Society of America says not to give them to kids under 4. 
5. Vitamins: Ultra-high doses of Vitamin C, the supposed cure-all, can lead to diarrhea. There are no major studies that prove Vitamin C can shorten the duration of a cold. Ditto for Vitamin E.
