How does this medication work? What will it do for me?

This medication contains two medicinal ingredients: hydrocodone and phenyltoloxamine. Hydrocodone belongs to the class of medications called antitussives (cough suppressants). Phenyltoloxamine belongs to the class of medications called antihistamines.

These two ingredients work together for the treatment of exhausting or non-productive cough that is associated with cold or with upper respiratory allergic conditions. Relief from the symptoms of coughing usually lasts between 8 to 12 hours. Hydrocodone is a narcotic medication. This medication is normally prescribed only after non-narcotic medications have been found ineffective.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
