Tussionex is an antihistamine used to provide relief from symptoms of the common cold or flu, including runny or stuffy noses, sneezing and coughing.
Histamine is a naturally occurring chemical in the body, and when too much is produced, it can cause sneezing, runny nose, and itchy, watery eyes.
Tussionex works to reduce these symptoms. The two active ingredients are chlorpheniramine and hydrocodone. Chlorpheniramine reduces the amount of histamine in the body, providing relief from cold and allergy symptoms, and hydrocodone is a cough suppressant.
The generic brand for Tussionex is chlorpheniramine and hydrocodone. It is also found under the brand names: Tussionex PennKinetic, TussiCaps, S-T Forte 2, Novasus, and HyTan.
Tussionex is a prescription antihistamine and should be taken exactly as prescribed by your doctor. Hydrocodone, an active ingredient, can be addicting, so it is important to take this medicine only as long as it is prescribed and at the correct dosage.
If you have overdosed on this medication, it is imperative to seek emergency help immediately. Overdosing on Tussionex can be fatal, especially for children.
