Opioids, Antihistamines, Antipsychotics, Anti-anxiety Agents, or Other CNS Depressants (Including Alcohol)
The use of opioids, antihistamines, antipsychotics, anti-anxiety agents, or other CNS depressants concomitantly with REZIRA Oral Solution may cause an additive CNS depressant effect and should be avoided.
Monoamine Oxidase Inhibitors and Tricyclic Antidepressants
Do not prescribe REZIRA Oral Solution if the patient is taking a prescription MAOI (i.e., certain drugs used for depression, psychiatric or emotional conditions, or Parkinson's disease), or for 2 weeks after stopping an MAOI drug. The use of MAOIs or tricyclic antidepressants with hydrocodone preparations may increase the effect of either the antidepressant or hydrocodone.

Drug Abuse And Dependence
REZIRA Oral Solution is a Schedule III controlled prescription containing hydrocodone bitartrate and should be prescribed and administered with caution.
Hydrocodone can produce drug dependence of the morphine type and therefore, has the potential for being abused. Psychic dependence, physical dependence, and tolerance may develop upon repeated administration of REZIRA Oral Solution, and it should be prescribed and administered with the same degree of caution appropriate to the use of other opioid drugs.
Psychic dependence, physical dependence, and tolerance may develop upon repeated administration of opioids; therefore, REZIRA Oral Solution should be prescribed and administered with caution.
Physical dependence, the condition in which continued administration of the drug is required to prevent the appearance of a withdrawal syndrome, assumes clinically significant proportions only after several weeks of continued oral opioid use, although some mild degree of physical dependence may develop after a few days of opioid therapy.
