Rezira (hydrocodone bitartrate and pseudoephedrine hydrochloride is indicated for relief of cough and nasal congestion associated with common cold. Common side effects with Rezira use can include respiratory depression, drug abuse and dependence, increased intracranial pressure, decreased mental alertness with impaired mental and/or physical abilities, as well as nausea and vomiting and constipation. Rezira should be used with caution in patients with diabetes, thyroid disease, Addison's disease, prostatic hypertrophy or urethral stricture, and asthma.
Rezira is for oral use only. Rezira should be dosed at 5 mL every 4 to 6 hours as needed, not to exceed 4 doses (20 mL) in 24 hours. Measure Rezira with an accurate milliliter measuring device. Do not use a household teaspoon to measure the dose. No specific drug interaction studies have been conducted with Rezira.
There are no adequate and well controlled studies of Rezira in pregnant women. Rezira should be used during pregnancy only if the benefit justifies the potential risk to the fetus. Caution should be exercised when Rezira is administered to nursing mothers. Hydrocodone and pseudoephedrine are excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Rezira Oral Solution, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
