Green Mucous -- What It Is and What It's SNOT
AddThis Social Bookmark Button

Editor's Note: This post, originally published on 12/1/05, has been updated to reflect today's withdrawal of all over-the-counter children's cold medications by the manufacturers.

Snot. noun. Middle English from gesnot. 1. Vulgar term for nasal mucous; phlegm. 2. A person regarded as annoying, arrogant, or impertinent (not your medical provider). Booger. Dried snot.

Yes, it's not easy to be green, especially if you are mucous in a kid. Why? Because a vast array of parents think that green mucous requires antibiotics. Green = Bad. Clear = Not bad yet.

Viral infections (colds) can cause a variety of mucous color changes in children...green, yellow, orange, brown, and of course, my favorite the multicolored. For the diligent mucous-watcher, these colors are very significant.

After sitting in a congested nasal passage all night, mucous becomes stagnant....just like a green pond. Bacteria love warm, dark, moist areas, so this is where they like to live. But, just because there is bacteria in the mucous, does not mean antibiotics are necessary. The purpose of mucous is to moisturize the air we breathe, and to trap those floating particles inhe air. It is suppose to drain...either out of our noses, or naturally, down the back of our throats.

"Green Nose in the Morning is No Cause for Warning". However, if a child has consistently green mucous from BOTH sides of the nose for over ten days, then your medical provider may take it more seriously. (Note: Green, smelly mucous from only ONE side of the nose of a child is likely to be a retained foreign body...usually food. And, you thought they ate those peas!)

Simple colds last a week if you treat them, and about seven days if you leave them alone; however, the nasal drainage can persists for weeks in children. This time of year, children tend to get exposed to "back to back" viral infections that run together and appear as one, prolonged cold. Children have a lower level of hygiene than other creatures on this planet, and germs are the most common thing they share. Day-care kids are like Velcro when it comes to viral infections. Since children get 6-9 viral infections per year, mostly in the fall/winter months, and colds can "run together"...then don't be surprised if your outgoing, day-care toddler has a runny nose from October to March.

Is there anything you can do about this? No. Well, actually yes.

1. Use saline nose sprays. They keep the mucous thin so it drains, and the nasal mucosa moist so it can do a better job in the dry, household air that we breathe. Cool mist humidifiers are also very helpful in the bedroom.

2. Encourage fluids. Hydrations helps to thin mucous.

3. Antibiotics do NOT work for viral infections. Ever. They don't prevent kids from getting sicker. Let your medical provider decide (without the begging, pleading, and coercion that often occurs). Antibiotics only work for secondary bacterial infections, like middle ear infections, sinus infection, Strep, etc.)

4. Be patient. Colds are inevitable. Cold are even considered biologically beneficial. What??? Cold are beneficial? You bet. Simple viral colds help jump start our immune system to make us more resistant to worse infections.

Hang in there, folks...

Thanks for the information I am a first time mom and my toddler just recently started daycare and I just started to notice the brightes green mucous I have ever seen, coming out my son's nose!!! With the information provided I took the time to calm down and realize my son had nothing more than just a good old fashion cold.

Thank you, I am a mom to a 27week preemie and it's so scary when my son seems to have any kind of infection, or sickness. He has been congested for a few weeks and now the drainage is somewhat green...I now realize with no other symptoms it's a cold.

Thank you for the information, I am a mother of a 7 year old daughter. she seems to have had a cold since the start of the winter. In the past i was eager to take her to the doctor, the last time i took her she saw a new pediatrician and when the doctor told me she did not need antibiotics i was a little shocked. Doctors are a little to eager to stuff medicine down their throats. sure enough the cold did clear up for a short time, before the next one.

Thanks, my son keeps picking up colds from our gym daycare. Though we have a great Pediatrician who only gives meds when needed and in a soft, easy way filled me in long ago on what to expect with colds and kids, your information was a little more varification for my husband who seems to think our son is dieing from all the sneezing and coughing that comes with colds. Though I feel bad for my baby we just have to push our way through this. Thanks

Sorry to say but Echinacea, Vitamin C and Zinc does help get rid of colds, even in Toddlers.

Thanks for the information!! Excellent article. My 4yo just started preschool, brought home a nasty nasal thing and passed it onto his younger twin brothers. Lots of green mucous around, and 'everyone' says he should be on antibiotics (as a microbiologist, I know better).

Echinacea does NOT seem to work in children....according to a well-designed, scientific study published in the medical journals, even if you personally feel that it helps. There are nothing wrong with using it, since it also appears to be harmless.

This is a great article. For nasal rinsing your toddler always remember to use a SNUB-NOSED BULB. Not the super-pointy bulb sent home with newborns! Many stores don't care snub-nosed bulbs, but Walgreen's is a good bet.

I got a question for anyone who might know what this is... I'm a 21yr old male and I have had broncitis before but not anymore, but since then i don't know if its that or something else: When I blow my nose my mucus is yellow/brown which looks like infection but its not thick or runny. I wipe my nose with a tissue and its yellow/brown and I don't know why, i don't feel ill or have anything like sinus headaches from an infection, I'm not even stuffed up!! I am curious if i need to see the doctor or what?! Any help would be great! Thanks.

coughing up nasty phlem for almost 2 months now. It started with my tonsils swelling constantly. I went to the doctor and he told me take an allergy medicine for a couple of weeks. I took claritin for a couple of weeks. The swelling went away in my tonsils and at the same time I developed what i thought was a cold. I've been couging up nasty phlem every since. i used to cough it up all day, now i cough in the morning, when it comes out i'm okay. Am i worried about nothing?

Hi, my 11 month old son has had a cold for the past month or so and we've taken him to see many doctors and even a specialist 3 times because his ear has been leaking green mucous usually found in the nose! we were told that his ear drum was pierced(and that its harmless) and that's why his mucus is coming through his ear instead of his nose.

he was antibiotics for 2 weeks, it went away for 3 days and now its back with a cough.

he's in the daycare, but even they are saying they've never heard of a runny nose via the ear.

i dont know what to do, as I have to take the specialist word that he doesnt have a major problem, just the cold, but are there any mothers out there who've had something similar happen to thier child?

thanks WorriedYoungMom

This was very helpful! I was just getting ready to call the doctor and take my two sons in. I'd rather save my money since he most likely would tell me they have a simple cold. No worries!

i am a first time mom of a toddler...he had a runny nose for acouple of weeks so i took him to the doctor and she gave him an antibiotic for 10 days...its been a week and he still has a runny nose! my home daycare provided was blaming my son for giving the other kids runny noses after he had been on the antibiotic for a week (and the kids are just getting sick, he still has 3 more days on the antibiotic) so i called my doc and also checked this website and everything my doc said is matching up with this. so i am printing and sending it to my daycare provider... kids are kids and will have runny noses... see how much she really nose(knows). lol

ok i've been feeling pretty crappy lately... i'm all stuffed up, i've got very thick almost hard brownish slightly bloody mucous coming out of both my nose and hanking it up. It's pretty gross... I have moments where I feel slightly drunk (i dont drink), my throat is very red, but it's not really that sore, it's the part where my nasal cavity meets my throat that hurts, well stings. Not to mention the sudden very painful tear jerking headaches... Should I go to the doctor? This came on quite suddenly.

I've had stuffed up sinuses for 3-4 weeks now. I went on vacation to the northeast, COLD TERRITORY. My nose got even worse. I'm don't think I'm sick because it's strictly my sinuses acting up. Usually I start with a sore throat if I'm getting sick. My sister gave me this generic nasal spray that works WONDERS, but you're not supposed to use it for more than 3 days apparently. It made my inner left nostril irritated or something because I get blood when I clean it out with a tissue or something. It was slightly brownish mucous all day, not a whole lot but it's annoying. Nasal spray works people, but it doesn't get rid of it. Now I have to lay off of it and let my inner nose heal while I suffer from not being able to freaking breathe.

I've been sick for five days now(fatique, mucus, cough, ear ache, sinus headache), and been a faucet turned on for snot. A couple of days ago I had a soccer game in the snow. (not smart but my team needed me) Today I woke up coughing and blowing green thick, and abundant mucus. Should I go to the doc or what?

I am 48 yrs old and in the morning my nose is stopped up. When I blow my nose, there is green mucus. After that is seems to clear things up. I can't remember having allergies, but it is spring time in Atlanta.

Ah, thanks for your comments, i'm going through a nasty cold right now that's mostly makes my throat sore, but with a runny nose. I'm trying different things at once to ease the pain, like throat spray, benadolyne(i probably didn't spell that right) and others..

I just wish it didn't drive me so crazy! Going to sleep is the worse, the worse :( I don't even wanna go to bed because it makes me feel so much more bad so quickly.. blah! I hope this goes away in a week!

Thanks for the good advice. Well written in lay terms. I'm 48 and you never really outgrow the wondering if and when you should go to the doctor!Our area has mutiple cases of H1N1 diagnosed so it's particularly concerning. I guess green mucous is not too concerning w/o fever, etc.

When doctors say it will last a week they mean usual a old week of 7 days. Sometimes they may mean the new wk also known as a business wk of 5 days.
