Use of extended release in children < 6 years
Cautions
Ingredients and dosage could change; ALWAYS check labeL
Use with caution in acute pancreatitis, Addison disease, cardiac arrhythmias, drug abuse/dependence, emotional lability, gallbladder disease, pseudomembranous colitis, GI surgery, head injury, myxedema, intracranial HTN, toxic psychosis, urethral stricture, seizures, acute alcoholism, emphysema, narrow angle glaucoma, asthma, prostatic hypertrophy, hypercapnia, renal/hepatic impairment, elderly debilitated patients
Respiratory depressant effects of narcotics and capacity to elevate cerebrospinal fluid pressure may be markedly exaggerated in presence of head injury, other intracranial lesions, or a pre-existing increase in intracranial pressure; narcotics produce adverse reactions, which may obscure clinical course of patients with head injuries
Administration of narcotics may obscure the diagnosis or clinical course of patients with acute abdominal conditions
Use with caution extended-release suspension in elderly or debilitated patients and those with severe impairment of hepatic or renal function, hypothyroidism, Addison's disease, prostatic hypertrophy, or urethral stricture for possibility of respiratory depression
MAO inhibitors or tricyclic antidepressants with hydrocodone preparations may increase the effect of either the antidepressant or hydrocodone
May cause dose-related respiratory depression (risk increased in children)
May impair ability to operate heavy machinery
Pregnancy and lactation
Pregnancy category: C; D if used for a prolonged period of time or in large doses near term; withdrawal symptoms or respiratory depression may be seen in babies born to mothers taking opioids
Lactation: Excretion in milk unknown/not recommended
Pregnancy categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA: Information not available.
