Uses For Rezira

Hydrocodone and pseudoephedrine combination is used in adults 18 years of age and older to relieve cough and nasal congestion (stuffy nose) caused by the common cold.

Hydrocodone is a narcotic antitussive (cough suppressant). It acts directly on the cough center in the brain to relieve cough. Pseudoephedrine is a decongestant, which decreases nasal congestion by narrowing the blood vessels and reducing blood flow to the nasal passage.

When hydrocodone 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.

This medicine is available only with your doctor's prescription.

Before Using Rezira

Geriatric
