Epistaxis: Changes in the nasal mucosa resulting from cold, dry weather in the wintertime can cause nosebleeding, or epistaxis. Sleeping in a humidified environment is recommended for prevention of recurrences in patients with anterior bleeds. Recurrent nosebleeds may be averted by applying topical Mupirocin or Bacitracin with a cotton swab to the nasal mucosa, but this has not been proven to be effective.
