Palpitations or respiratory distress, as well as nasal obstruction, may occasionally occur, necessitating caution if these symptoms appear.

Patients with seasonal allergies should start taking the medication before the worsening of symptoms and continue during the symptomatic period. This medication does not seem to enhance sedation when used with other sedatives or alcohol, but caution is recommended due to limited coadministration experience.

The elderly are often at risk for adverse reactions due to decreased liver and kidney function, so symptoms should be closely monitored and dosages adjusted as necessary. In cases of overdose, arrhythmias and other cardiac abnormalities may occur, so if suspected, immediate EKG testing at a hospital and treatments such as gastric lavage or diuresis should be initiated.
