How to Prevent Nosebleeds
You can’t always prevent nosebleeds from happening, but there are certain things you can do to help lower your chances of getting them:
Keep the inside of your nose moist. Dryness can cause nosebleeds. Use a cotton swab to gently smear a thin layer petroleum jelly in your nostrils three times a day, including before you go to sleep. You can also use an antibiotic ointment like Bacitracin or Polysporin.
Use a saline nasal product. Spraying it in your nostrils helps keep the inside of your nose moist.
Use a humidifier. Your nostrils might be dry because the air in your house is dry.
Don’t smoke.Smoking can irritate the inside of your nose and dry it out.
Don’t pick your nose. Also, don’t blow or rub it too hard. If your child is getting nosebleeds, keep their fingernails short and discourage them from picking their nose.
Don’t use cold and allergy medications too often. These can dry out your nose. In some cases, certain medications can cause nosebleeds or make them worse. You may need to discuss your medications with your doctor. But keep taking them unless your doctor tells you to stop.
