The U.S. Food and Drug Administration (FDA) has approved a new drug application (NDA) for Rezira (hydrocodone bitartrate and pseudoephedrine hydrochloride) Oral Solution (CIII) for the relief of cough and symptoms associated with the common cold.
What is Rezira used for?
Rezira is used for:
- Relieving congestion and cough due to colds, flu, or hay fever. It may also be used for other conditions as determined by your doctor.
What is Rezira?
Rezira is a decongestant and cough suppressant combination. It works by constricting blood vessels and reducing swelling in the nasal passages. This allows you to breathe more easily. The cough suppressant works in the brain to decrease the cough reflex to help decrease a dry cough.
Do NOT use Rezira if:
- you are allergic to any ingredient in Rezira or any other codeine or morphine related medicine (eg, codeine, oxycodone).
- you have severe high blood pressure, rapid heartbeat, or other severe heart problems (eg, heart blood vessel disease)
- you take sodium oxybate (GHB) or if you have taken furazolidone or a monoamine oxidase (MAO) inhibitor (eg, phenelzine) within the last 14 days
Contact your doctor or health care provider right away if any of these apply to you.
