Anticholinergic nasal sprays

Ipratropium bromide (Atrovent) is used to reduce runny nose.

• How anticholinergic nasal sprays work: When sprayed into each nostril, anticholinergic nasal sprays decrease secretions from the glands lining the nasal passage. This diminishes the symptom of runny nose.

• Who should not use these medications: Individuals who are allergic to any components of the nasal spray should not take this drug.

• Use: The usual dosage is 1-2 sprays in each nostril 2-3 times per day.

• Drug or food interactions: Since this spray has little or no effect beyond the area applied, it is unlikely to interact with other drugs.

• Side effects: Anticholinergic nasal sprays may cause an excessively dry nose, thereby causing nosebleeds or irritation.
