Does green nasal drainage mean I need an antibiotic?

No. It is likely at some point you have heard someone state they need an antibiotic because they have green nasal discharge. Evidence has demonstrated that is not accurate. Often times green nasal drainage is caused by viruses. Antibiotics are not effective at treating viruses. When these infections first begin, the nose begins to produce clear mucus. This is the body’s way of getting rid of the virus from the nose and sinuses. After a few days, the immune system kicks in resulting in the mucus turning white or even yellow. Throughout our body we have protective bacteria called “normal flora” which helps keep us healthy. When the body starts to recover from the viral infection, the bacteria (normal flora) in the nose begins to grow back resulting in green colored mucus.

If antibiotics are prescribed in instances when they are not needed, this can result in resistant bacteria, which means the bacteria is no longer susceptible to the antibiotic. Additionally, there are the risks of side effects from the medication including but not limited to rash, dizziness, stomach problems, yeast infections, etc.

To help with the symptoms of a runny nose during a cold you can:

• Drink plenty of fluids
• Use a cool mist humidifier
• Use saline nasal spray or drops
• For younger children, you can use a rubber suction bulb to clear mucus
• Older children can breathe in steam from a bowl or hot shower
• Be sure to ask your provider or pharmacist about over-the-counter medications to help with your symptoms.
