What is in tussionex syrup?

Tussionex syrup is a prescription medication that is used to treat coughs. It contains two main ingredients: hydrocodone and chlorpheniramine.

Hydrocodone is an opioid cough suppressant that works by blocking the cough reflex in the brain. It can also cause drowsiness, dizziness, and nausea.

Chlorpheniramine is an antihistamine that helps to relieve allergy symptoms, such as sneezing, runny nose, and itchy eyes. It can also cause drowsiness and dizziness.

Tussionex syrup is available in two strengths: 10 mg/5 ml and 15 mg/5 ml. The usual dosage for adults and children over 12 years old is 5 to 10 ml every 4 to 6 hours, not to exceed 60 ml in 24 hours. The usual dosage for children 6 to 12 years old is 2.5 to 5 ml every 4 to 6 hours, not to exceed 30 ml in 24 hours.

Tussionex syrup should not be used by people who are allergic to hydrocodone or chlorpheniramine, or who have certain medical conditions, such as asthma, emphysema, or severe liver disease. It should also not be used by pregnant women or nursing mothers.

Tussionex syrup is a controlled substance, and it can be habit-forming. It should be used only as directed by a doctor.
