Clinical studies of Histinex® HC (phenylephrine, hydrocodone, cpm) syrup did not include sufficient numbers of subjects aged 65 and over to determine whetherthey respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Sedating drugs may cause confusion and over-sedation in the elderly; elderly patients generally should be started on low doses of Histinex® HC (phenylephrine, hydrocodone, cpm) syrup and observed closely.

Hypersensitivity to antihistamines of the same chemical class. Histinex® HC is contraindicated during pregnancy and in concurrent therapy with MAO inhibitors. Because of its drying effect on lower respiratory secretions, Histinex® HC is not recommended in the treatment of bronchial asthma.
Histinex® HC (phenylephrine, hydrocodone, cpm) reduces excessive nasal secretions, diminishes edema of the nasal mucosa and congestion of the upper respiratory tract and abolishes or diminishes cough. The antihistaminic action of chlorpheniramine maleate reduces or abolishes allergenic responses of nasal tissue. Its action is complemented by the mild vasoconstrictor action of phenylephrine hydrochloride which provides a nasal decongestant effect. Cough suppression is a result of the action of hydrocodone bitartrate.
