Nosebleeds may develop in people who have colds or
chronic hay fever symptoms (postnasal drip, sneezing, or a runny, stuffy, or
itchy nose) because nasal tissues become inflamed and irritated. Using
medicines may relieve the symptoms, leading to less inflammation and irritation
and fewer nosebleeds. But overuse of allergy medicines may lead to nosebleeds
because of their overdrying side effects. If you have a lot of nosebleeds, talk
to your doctor about the proper use of cold and allergy medicines.
If you are helping someone else stop a nosebleed, avoid touching the
other person's blood. Use gloves, if available, or layers of fabric or a
plastic bag to protect yourself.
