What causes dry nose?
Many medications produce side effects including dry nose. Common drugs that result in dry nose are antibiotics, antihistamines and decongestants. Overuse or abuse of drugs used to relieve congestion, especially nasal sprays, will dry the nose.
Environmental conditions with low humidity also result in dry nose. Extreme heat or arid conditions do not provide adequate relative humidity for the nasal passages, and they become dry. Dryness in the nasal passages is unhealthy for the entire respiratory system, as the nose is the main humidifier of inhaled air that travels to the lungs. The mucous membranes that line the respiratory system require humidity to work properly, as does saliva in its role as a mouth cleanser.
Sjogren’s syndrome is an autoimmune disorder that attacks the mucus and moisture-producing glands of the body. It is characterized by dry eyes and mouth, but individuals who have this syndrome may also experience dry nose.
Common causes of dry nose

Serious or life-threatening causes of dry nose
In some cases, dry nose may be a symptom of a serious or life-threatening condition that should be immediately evaluated in an emergency setting. These conditions include severe infections of the respiratory system.
