Common Cold Myths and Sniffs

The most common cause of the common cold is Rhinovirus, which accounts for nearly 75 per cent of confirmed cold cases. Most adults catch two to three colds per year, but kids can catch up to eight. Stress and poor sleep are factors that make you more likely to catch a cold, whereas infants and young children in daycare get sick more frequently because they are in close contact with each other.

The best approach to staying healthy is to wash your hands frequently, wear a mask, and stay home if you are sick. If you are considering some popular herbal and other cold remedies, ASEBP’s pharmacist offers the following information:

• Vitamin C: a daily adult dose is between 1-5 mg a day, taken orally. Research on vitamin C is limited and while it’s generally considered a no harm/no gain supplement, it may only prevent colds in specific populations (e.g., endurance athletes) and there is no effect once an individual is sick.   
• Ginseng (Cold-FX): inconsistent data and unclear benefits related to the prevention or treatment of the common cold. 
• Herbal products (echinacea, oregano): Always speak with your pharmacist as some herbal products can have adverse effects when used in combination with prescription medication for chronic conditions (e.g., blood thinners, blood pressure, diabetes).  
• Neti pot or saline (nasal) sprays: unclear benefits, although there is potential risk of harm if equipment is not washed and sterilized between uses.
