What can you do for a cold? continued...

You may decide to try a cough, cold, or allergy medicine for your symptoms. Be safe with medicines. Read and follow all instructions on the label slideshow.gif. Don't take cold medicine that uses several drugs to treat different symptoms. For example, don't take medicine that contains both a decongestant for a stuffy nose and a cough medicine. Treat each symptom on its own.

Be careful with cold medicines. They may not be safe for young children, so check the label first. If you do give these medicines to a child, always follow the directions about how much to give based on the child's age and weight. For more information, see Quick Tips: Giving Over-the-Counter Medicines to Children.

Alternative medicines or supplements

Some people try complementary or alternative medicines to prevent colds or to shorten their cold symptoms. Before using any treatment for your cold symptoms, it is important to consider the risks and benefits of the treatment. For more information, see the topic Complementary Medicine. Some of the medicines being studied are:

  • Echinacea. Study results differ about whether echinacea can keep you from getting a cold or can help you get better faster. Echinacea can cause severe allergic reactions in some people with a history of asthma, allergies, hay fever, or eczema.
  • Vitamin C. Long-term daily use of vitamin C in large doses does not appear to keep you from getting a cold or help you get better faster. There may be a slight reduction in the length of time cold symptoms last when high doses are taken. Additional studies must be done to determine how much vitamin C is needed to reduce the length of time cold symptoms are present.
  • Zinc. Using a product containing zinc may help shorten the length of your cold by up to a day.1 But you have to take the zinc as soon as you have any cold symptoms. In some cases, zinc products that you spray or place into your nose can cause permanent loss of the sense of smell.2

If you decide to use an alternative medicine or supplement, follow these precautions:

  • As with all conventional medicines and supplements, it is important to follow the directions on the label.
  • Do not exceed the maximum recommended dose.
  • If you are or could be pregnant, talk with your doctor before taking any medicine or supplement.
  • If you have another health problem or take prescription medicines, talk with your doctor before taking an alternative medicine or supplement.
