Concerns related to adverse effects:
• CNS depression: May cause drowsiness in some patients; instruct patient to use caution when driving or operating machinery. Effects may be additive with CNS depressants and/or ethanol.
• Nasal ulcerations: Periodically examine nasal mucosa for ulceration and consider discontinuing if ulceration occurs.
Observe patients periodically for adverse nasal effects (eg, ulceration, perforation).
Pregnancy Risk Factor
Adverse effects were observed in animal reproduction studies. Until additional information is available, other agents may be preferred for the treatment of rhinitis in pregnant women (Scadding 2008).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience headache, pharyngitis, or bad taste. Have patient report immediately to prescriber nasal sores, severe nasal irritation, noisy breathing, or severe nosebleeds (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
