Tussionex is a prescription cough suppressant used to relieve coughs caused by allergies, the common cold, or the flu. It contains the active ingredient hydrocodone, which is an opioid that works by decreasing the activity of the cough center in the brain.
Tussionex is available in both liquid and tablet form. The liquid form is typically used for children, while the tablet form is used for adults and children over the age of 12. Tussionex should be taken as directed by a doctor. The usual dose for adults and children over the age of 12 is 5 to 10 mL of the liquid or 1 to 2 tablets every 4 to 6 hours as needed.
