Triprolidine, pseudoephedrine, and codeine combination is used to relieve cough, sneezing, itchy or runny nose, and nasal congestion (stuffy nose) caused by allergies or the common cold.

Triprolidine is an antihistamine that works by preventing the effects of a substance called histamine, which is produced by the body. Histamine can cause itching, sneezing, runny nose, and watery eyes. Pseudoephedrine is a decongestant, which decreases nasal congestion by narrowing the blood vessels and reducing blood flow to the nasal passage. Codeine is a narcotic antitussive (cough suppressant). It acts directly on the cough center in the brain to relieve cough.

When codeine is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing cough and nasal congestion should not let the fear of dependence keep them from using narcotics to relieve their cough. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.
