 Most of us have had the experience -- walking outside on a cold, winter day, and your nose turns into a faucet. You're not sick, and your nose wasn't running when you were indoors. But the cold (or windy) weather does it every time -- you need Kleenex around just so your nose doesn't drip all over your face and clothes. What's the deal? It's not an allergy, but a non-allergic phenomenon known as vasomotor rhinitis. Most allergy medicines won't help these symptoms -- but if symptoms are severe, or you're planning on spending lots of time outdoors in cold weather -- there is a prescription nasal spray called ipratropium bromide that can dry up that drip.


Runny Noses in Cold Weather
It could be allergies caused by pollen or mold in the air, but when you only have a runny nose when outdoors, it is most likely because of vasomotor rhinitis, which is a type of nonallergic rhinitis caused by changes in temperature, humidity and exposure to strong odors and perfumes. Usually, a person with vasomotor rhinitis will have production of clear nasal discharge that may drain out of the front of the nose, down the back of the throat or result in nasal congestion.

Non-Allergic Rhinitis
Non-allergic rhinitis is a medical condition of unknown cause, leading to symptoms very similar to allergic rhinitis, or hay-fever. Approximately half of people suffering from allergies also have a non-allergic component to their symptoms. Unlike allergies, which can be a seasonal problem, symptoms of non-allergic rhinitis are typically year-round. Non-allergic rhinitis also tends to be more common as people age, whereas allergic rhinitis tends to affect children and young adults. Non-allergic rhinitis has many different forms...

Symptom-Based Approach to Treatment of Allergies
For the person with nasal allergy symptoms, the choices of available medicines can be daunting. From pills to nasal sprays, it can be quite difficult to decide which medication is best for your symptoms. While there is no one-size-fits-all allergy medicine, there may be better choices based on the kind of symptoms you're experiencing.
