The common cold is a ritual for most individuals, who usually get infected with it several times per year. Cough syrups, nasal decongestants and chicken soup are the typical remedies to ease symptoms. However, medications to prevent the common cold may be more helpful. These prevention potions are easily accessible over-the-counter and range from herbs to vitamins. Commonly used medications like Airborne and Zicam are used to reduce the duration of colds, and may help the body ward off infection.
Vitamin C
For most individuals, taking vitamin C for the prevention of colds is ineffective. Taking 200mg or more, however, can help prevent colds among those who are either extremely active or exposed to exceedingly cold temperatures, according to the Mayo Clinic. These individuals include marathon runners, soldiers and skiers. Excessive amounts of vitamin C supplements (more than 2,000mg daily) could have side effects such as diarrhea and nausea.
Echinacea
Echinacea is a traditional remedy thought to stimulate the immune system. Its uses include treatment and prevention of the common cold, flu and infections. It has also been used to treat wounds and skin conditions, including acne and boils, according to the National Center for Complimentary and Alternative Medicine. Echinacea is available in various forms such as teas, and is a significant ingredient in popular cold-prevention remedies like Airborne. Studies are mixed regarding the effectiveness of the remedy. According to the Mayo Clinic, some studies show a 10 to 30 percent reduction in the severity and reduction of colds when the herb is taken for seven to 10 days at the arrival of a cold.
Zinc
Zinc is another commonly used remedy that is a vital ingredient in over-the-counter cold prevention medications like Airborne and Zicam. It is an essential mineral with antioxidant effects, making it a vital component for fighting and resisting infection. Similar to echinacea, the research regarding effectiveness is mixed. However, the studies showing affirmative results indicate the remedy is most effective when taken in the form of a nasal spray or lozenge. Side effects can be harsh in some cases (when taken nasally), causing lasting damage to the sense of smell, according to the Mayo Clinic. Other Zicam products include RapidMelts with vitamin C and echinacea, cold and flu daytime and nighttime liquids, and sinus sprays and nasal gels.
